1. A Hawlean strategy

Both Elzinga (Reference Elzinga2018) and Löwenstein (Reference Löwenstein2017) incorporate elements of Hawley's (Reference Hawley2003) account of knowing how to φ, and both accounts (Elzinga's explicitly, Löwenstein's less explicitly) follow a Hawlean strategy for ensuring that their respective diagnoses will match our pre-theoretic intuitions about who knows how to φ (i.e. for ensuring the extensional adequacy of the views).Footnote ² The strategy begins by distinguishing agents’ abilities to meet standards reliably across a relevant range of performance conditions from the possibility of agents getting lucky and performing in a standard-meeting way as a result. Such reliable abilities form the foundation of these accounts, and provide a response to putative counterexamples involving fluke or lucky success.

The next step in the Hawlean strategy is to put additional conditions on knowing how to φ, conditions that, among other things, provide a response to additional putative counterexamples. For example, Elzinga's second self-regulation condition rules out cases like Hawley's baker, who doesn't know how to bake a cake, yet has the good fortune to be surrounded by all and only the correct ingredients for cake baking and happens to be disposed to throw them together in the correct way (and would thus seem to meet the first condition) (Elzinga Reference Elzinga2018: 129–30). Löwenstein's normative guidance conditions provide for the distinction between the exercises of genuine knowledge-how and the performances of clocks and trained animals (who would also seem to meet the first condition) (Löwenstein Reference Löwenstein2017: 30–1). Hawley's warrant condition rules out cases of several types, including that of a smoker who knows that they annoy someone but is mistaken about why (but who would nevertheless seem to meet the first condition) (Hawley Reference Hawley2003: 28).

2. Conflating two types of conditions

But characterizing knowing how to φ in this way conflates the range of conditions a particular performance method (or style) equips an agent to cope with, and the range of conditions under which a particular agent can reliably perform according to that method (or style). Consider a baker who knows how to bake a cake. According to Hawley, Elzinga, and Löwenstein, the baker's knowing how to bake a cake is partly grounded in their ability to reliably bake a proper cake across a certain range of performance conditions.Footnote ³ For Elzinga and Löwenstein, the ability must be robust in the right way – the relevant range of performance conditions must not be restricted to only those conditions under which the agent gets lucky somehow (Löwenstein Reference Löwenstein2017: 25–9; Elzinga Reference Elzinga2018, 120–3). It is plausible that, for many agents who know how to bake a cake, this range of tolerable performance conditions will include some variation in things like the availability of different kinds of cake pans (e.g. shallow pans vs deeper pans), and local altitude and humidity (e.g. Kansas City vs Tucson). It is also plausible that for some agents this range will also include variation in things like the amount of coffee consumed before cake baking, and the presence or absence of certain psychological stressors.

But the conditions just mentioned are of two different types. Most competent bakers’ ability to succeed with either a shallow pan or a somewhat deeper pan, in Kansas City or in Tucson, is grounded in the fact that they check their cakes with a skewer (or fork; toothpick; fingertip; etc.) to determine how far along they are in the baking process. (Deeper pans tend to require longer baking times; higher altitudes can require shorter baking times.) A cake is done when it is done, and if a baker checks their cake, they can cope with a certain amount of variation in baking time that can occur for a variety of reasons. Checking one's cake is part of a method of baking cakes.

On the other hand, if a competent baker can make it work after having four cups of coffee, or after having no coffee at all, this usually isn't grounded in their method of baking cakes. Rather, it is usually a condition of their ability to execute their cake making method, a condition that is grounded in their not being addicted to, or overly sensitive to, caffeine. There are innumerable conditions that a method cannot control for but must presuppose. To illustrate, a cake recipe cannot provide instructions, so to speak, all the way down – it is only against a background of basic competencies that any particular recipe is useful. Recipes don't tell you how to measure ingredients, but even if they did, they could only do so in terms of other competencies that are themselves presupposed.

A particular method of baking, once it has been mastered, will itself equip the agent using it to cope with certain kinds of variation in performance parameters. Nevertheless, just because someone bakes according to a method that equips them to cope with certain variations in pan shape, altitude, etc., doesn't mean that as long as the pan shape, altitude, etc. are within the tolerable limit they can reliably bake a cake. A particular agent may also need to have had at least two cups of coffee, or to have had no coffee whatsoever, or to be free of certain psychological stressors, to reliably execute their cake baking method. (For in times of profound distress, or when suffering caffeine withdrawal, some agents may tend to forget to add an ingredient or to check the cake.)

But to identify the set of conditions under which an agent can reliably φ in a standard-meeting way, even where these conditions are ones in which the agent meets certain additional constraints (e.g. self-regulation; normative guidance; warrant), is not yet to distinguish between the variation in these conditions that is provided by the method itself (e.g. shallow vs deeper pans, low altitude vs middle altitude), and the variation that represents the particular agent's ability to reliably execute that method (e.g. plenty of coffee vs no coffee; the presence or absence of certain psychological stressors; etc.).

3. An amendment

I'd like to propose an amendment to accounts like those of Elzinga and Löwenstein. After proposing this amendment, in the next section I'll argue that the distinction the amendment provides for should be a part of any satisfying ability-based account of knowledge-how. As I will argue in the last section of the paper, this is especially true for accounts that also strive to function as interpretations of Ryle's own view about the nature of knowledge-how.

I'll start with the second condition. I propose that self-regulation, and normative guidance, be understood as characterizing a method (or style) that an agent is able to φ according to. For Elzinga's account, this would mean that an agent can φ sensitively to the results of previous trials (e.g. by means of a method that includes explicit planning based on previous results, or by means of less conscious behavioral tendencies), and in a way that simultaneously allows the current φing to itself function as a trial to inform future φings (e.g. with sufficient presence of mind for the φing and its results to be recallable later).Footnote ⁴

For Löwenstein's account, this would mean, as per Löwenstein's characterization of intellectual guidance, that an agent is able to φ according to a method that involves conceptualizing the relevant act types or tokens, and the relevant performance condition types or tokens, and making judgements about the degree to which normative standards for φing can be met by such acts in such conditions, and acting on the basis of these judgements.Footnote ⁵

Now for the first condition. I propose that we understand the range of relevant performance conditions as, more precisely, a range of relevant values in relevant performance parameters that the methods characterized by the second condition equip an agent to cope with. Knowing how to φ would then require that, so long as the agent is able to execute the method for φing described by the second condition, their meeting normative standards in φing will not be prevented by certain variation in the values of certain parameters – e.g. whether the baker has glass mixing bowls or metal bowls to work with; whether they are baking in Kansas City or in Tucson; etc.

Understood in this way, the range of relevant performance conditions will be equivalent to a set of possible worlds, but which set this is will depend on the answer to at least one philosophical question that is independent of the issues that I am pressing in this paper. Allow me to explain.

We can characterize the range of relevant performance conditions in a way that is halfway between the informal characterization given above and the precise characterization of a determinate set of possible worlds.Footnote ⁶ Let a performance condition for φing be a way that the world can be, a way that is individuated on the basis of the opportunities for φing and challenges to φing that it presents.Footnote ⁷ My proposal for the first condition then comes to this: Those performance conditions for φing under which an agent can successfully execute their method for φing, and under which, if they managed to meet normative standards for φing, they would be meeting these standards because they managed to execute their method, are not individuated on the basis of certain parameter values that we expect the method itself to equip them to cope with. In other words, for an agent who knows how to bake, having specifically glass (or, alternatively, specifically metal) mixing bowls to work with is neither required for their being able to execute their method (as having plenty of coffee might be), nor has the power to undermine their successfully meeting normative standards in baking by means of the method (or to bring about a Gettierized meeting of these standards).Footnote ⁸

To further refine the set of relevant performance conditions into a determinate set of possible worlds, one must first answer the following independent, philosophically interesting question: To what extent does a (knowledge-how-constituting) competency (or skill, etc.) guarantee the meeting of normative standards in φing? If one thinks that to know how to φ in circumstances C one must have a competency that guarantees meeting normative standards for φing in C, then the set of relevant performance conditions will be identical to the set of worlds in which one would meet standards in φing if one tried to use one's method for φing. This draws one closer to Hawley's (Reference Hawley2003: 22) view. On the other hand, if, like Elzinga (Reference Elzinga2018: 121) and Löwenstein (Reference Löwenstein2017: 28) one thinks that one's competency need only reliably (though not perfectly) guarantee meeting normative standards, then the equivalent set of worlds becomes a bit more abundant. Alternatively, if one thinks that one's competency need only make meeting standards more likely than some benchmark level (for example, even though the best batters in professional baseball only manage to hit league pitches less than half of the time, their batting average is still much higher than that of an amateur) then the equivalent set of possible worlds might be more abundant still.

If adopted, my proposal for the first condition provides a clarification of the views of Elzinga and Löwenstein, especially as regards distinct dimensions of performance robustness.Footnote ⁹ My proposal for the second condition, while providing complementary discussion to both the views of Elzinga and Lowenstein, will constitute a revision only to Elzinga's account, since Löwenstein, for the most part, already exposits the second condition of their view this way (Löwenstein Reference Löwenstein2017: 122–9). Elzinga suggests that agents manage to make trials and respond to feedback in their performances by means of dispositions to do these things, and by ‘dispositions’ I take Elzinga to mean more-or-less persistent, standing tendencies (Elzinga Reference Elzinga2018: 133). Such agents may meet my version of the second condition, but my version of this condition may also be met by agents who, often enough, are unimaginative in their attempts and ignore the lessons of past failures. Such agents may still meet my version of the second condition, provided that they are able, under some conditions or other, to perform in a reliably resilient and conscientious way (and provided that they've already learned that performance method or style).Footnote ¹⁰

But is it really enough for knowing how to φ that one is able (under some conditions or other) to execute a method that, when executed, equips the agent to cope with certain variations in the values of certain performance parameters?

It is enough, and we don't need to require that the ability to execute such a method be itself robust across any particular conditions. The reason why is one of the most important contributions of this paper. Recall that the preeminent function of the original first condition was to provide a response to putative counterexamples in which someone who doesn't know how to φ nevertheless, through sheer luck or with scaffolding from exceptionally accommodating performance conditions, manages to meet normative standards for φing.

But to depend on luck or exceptional performance conditions when meeting standards is not to meet these standards by means of the methods that I have been discussing. (For such methods equip an agent to non-accidentally cope with variation in performance conditions.) Therefore, the agent who can only meet standards with the assistance of luck or exceptional performance conditions cannot execute such methods at all. So it's not that the novice can do what the expert can do, but only in a smaller range of performance conditions. Rather, the novice cannot do what the expert does under any performance conditions, at least not until the novice masters the methods, styles, techniques, etc. by which the expert non-accidentally copes with variation in performance parameters. Once this is recognized, we no longer need to appeal to the general robustness of an ability in excluding cases of lucky success as cases of knowing how to φ, for the relevant ability (i.e. the ability to execute certain methods) is not possessed at all by the agent that must get lucky. (The argument for this will be elaborated on in the last section of the paper.)

4. Motivating the amendment

Above, I've argued that there is an important distinction between the range of performance parameter values that a particular performance method (or style) equips an agent to cope with, and the range of conditions under which a particular agent can reliably perform according to that method (or style). I've also argued that, once we identify knowing how to φ with an ability to φ according to a certain kind of method, we don't need to appeal to the conditions under which an agent can reliably execute such a method to secure the extensional adequacy of the account.

I'll now argue that these theses can do important work in an account of knowing how to φ. I will do this by first considering a kind of objection to the accounts of Hawley and Elzinga involving two agents who, plausibly, possess the same piece of knowledge-how. I will then show how my proposed amendment to these accounts provides a response to this kind of objection. Following this, I will consider a case in which two agents each possess what is plausibly a different piece of knowledge-how. After discussing the way in which Löwenstein's view can accommodate such a case, I will then show how Elzinga's account can, if amended in the way that I propose, accommodate it as well.

5. Sleeping on the job

Hawley's (Reference Hawley2003: 21–2) view relativizes the content of what is known when one knows how to φ to those circumstances under which the agent would succeed in φing if they tried. That is, according to Hawley, the content of what one knows when one knows how to φ is always how to φ under circumstances C. Waights Hickman (Reference Waights Hickman2019: 316–17) objects to relativizing the content of knowledge-how in this way, partly because doing so seems to entail the implausible claim that Mozart and Bach possessed different pieces of knowledge-how if Mozart could compose drunk but Bach could not.

Elzinga's view escapes this version of the objection for, according to my reading of the view, one who knows how to φ need only be able to φ (in a standard-meeting way) reliably across a range of performance conditions determined by the context of the knowledge attribution (Elzinga Reference Elzinga2018: 121, 123). In many contexts, the performance conditions relevant to ‘so-and-so knew how to compose’ include (relative) sobriety, so ‘Mozart knew how to compose’ and ‘Bach knew how to compose’ can both be true when said in such contexts.

Even so, a similar objection to Elzinga's view, on my reading of it, can be developed. Consider Ben and Jerry, two partners in an ice cream business. Both Ben and Jerry know how to catch their partner sleeping on the job. Their methods for doing so may both be identical, for example, check the storeroom, and the area behind the freezer, between 2:30 and 3:30 in the afternoon. Such a method equips both Ben and Jerry to cope with certain variations in performance conditions, for example, they can each succeed regardless of whether their partner has chosen to nap in the storeroom or behind the freezer. Even so, there is no possible world in which both Ben and Jerry succeed (at least within a certain interval of time), because for Ben to catch Jerry sleeping, Ben cannot himself be sleeping, and thus cannot himself be caught sleeping. For this reason, if the contextually relevant performance conditions are understood as a single set of worlds in which both Ben and Jerry can succeed, it appears that, according to Elzinga's account, there is no single context in which ‘Ben knows how to catch a partner sleeping’ and ‘Jerry knows how to catch a partner sleeping’ can both be true.

Of course, one might try to understand these contextually relevant performance conditions as something other than a single set of possible worlds in which both Ben and Jerry can succeed. And this is partly what my amendment provides by recasting these conditions as performance parameters, or to put it another way, as a certain required variability within the set of performance conditions under which an agent can execute their method and meet normative standards as a result (if standards are indeed met, and regardless of whether the equivalent set of possible worlds is, so to speak, abundant or sparse). Since both Ben and Jerry can cope with the same variations in performance parameters as a result of the same methods, they both know the same thing, despite not both being able to exercise this knowledge at the same time.

Löwenstein's view is already immune to this kind of objection, for according to that account, the content of the knowledge-how attribution is relativized, not to a single set of contextually relevant performance conditions, but to those performance conditions under which the subject of the attribution can themselves reliably meet normative standards in φing (Löwenstein Reference Löwenstein2017: §1.4). This is how Löwenstein's version of the first condition works: If an agent knows how to φ, then they are able to reliably meet normative standards in φing in those performance conditions in which they are not substantially impeded from doing so (Löwenstein Reference Löwenstein2017).

But what counts as a substantial impediment can vary from agent to agent. Ben cannot catch Jerry sleeping if Jerry is awake, and vice versa. Nevertheless, Löwenstein can account for Ben's possessing the same knowledge-how as Jerry by appealing to the identical stock of concepts through which Ben and Jerry each assess their performances and opportunities, and each non-accidentally succeed at catching their partner sleeping as a result (within what, for each of them respectively, are the normal conditions) (Löwenstein Reference Löwenstein2017: 115–22). Part of what my proposed amendment does is generalize this aspect of Löwenstein's view by recasting any performance robustness that is to be partly constitutive of knowing how to φ in terms of performance parameters.

6. Two ways of solving a Rubik's cube

In the previous section I discussed an objection to Elzinga's account (adapted from an objection to Hawley's account made by Waights Hickman (Reference Waights Hickman2019: 316–17)). This objection involved two agents who, plausibly, possess the same piece of knowledge-how. I discussed how Löwenstein's view escapes this objection, and how my proposed amendment generalizes this feature of Löwenstein's account such that accounts like Elzinga's can be amended to include it as well.

In this section I'll discuss how much the same is true of certain cases involving agents who each possess what is plausibly a different piece of knowledge-how. Consider two agents who can both speed-solve the Rubik's cube within the same amount of time, and with the same degree of reliability. (If, like Hawley, we wished to additionally relativize the content of knowledge-how to the conditions under which an agent would, or could, succeed, we can stipulate here that both of these agents can similarly speed-solve the Rubik's cube under exactly the same conditions, down to the last detail.)

But suppose additionally that each of these agents has learned only one method for speed-solving the Rubik's cube, and that they have each learned different methods. The first agent uses only the Advanced CFOP method, whereas the second agent uses only the Roux method.

Both of these agents know how to speed-solve the Rubik's cube, but there is a difference in their knowledge. But if knowing how to speed-solve the Rubik's cube is a matter of being able to reliably meet normative standards in doing so (e.g. speed; no cheating; etc.), and this across a certain range of performance conditions, then how are we to distinguish the difference in what they each know?

The only available response seems to be this: One agent knows how to speed-solve the Rubik's cube using the Advanced CFOP method, while the other agent knows how to speed-solve the Rubik's cube using the Roux method. But this is, in a sense, just what my proposed amendment is all about. For once we describe the relevant φing methodologically, we can exclude, as cases of knowledge-how, cases of lucky success without needing to appeal to a generally reliable ability.

This is because, as discussed above, someone who, through sheer luck, manages to speed-solve the Rubik's cube isn't solving it using the Roux method. Even if, by sheer luck, this person manipulates the Rubik's cube just as someone who is using the Roux method would, still this person isn't using the Roux method. (An argument for this would fall out of my reading of Ryle's various discussions of intelligence, semi-hypothetical statements, and ‘heed’ concepts. This reading will be articulated in the next section.)

What's more, while we expect that an agent who knows how to speed-solve the Rubik's cube can cope with certain kinds of variation (e.g. the agent can speed-solve a Rubik's cube that has been scrambled into a variety of starting states), it is plausible that the ability to cope with these kinds of variation is provided by the method of puzzle solving itself.

Löwenstein's view can explain both the similarity, and the differences, in what these agents know. According to this view, their knowledge-how is similar in that they both meet the same normative standards in speed-cubing under the same performance conditions, and both as a result of normative guidance (Löwenstein Reference Löwenstein2017: 122–3). But this view can also diagnose the difference in their knowledge-how by appealing to the different concepts that structure this normative guidance: Whereas one of the agents deploys the concept of the First Two Layers, the other agent deploys the concept of the First Two Blocks, etc.Footnote ¹¹ My amendment makes a similar resource available to any ability-based view that follows the Hawlean strategy, in particular Elzinga's view, and does this by recasting Elzinga's self-regulation condition in methodological terms.

7. Ryle on ‘thinking what one is doing’

In this section I'll argue that amending Elzinga's and Löwenstein's Ryle-inspired accounts in the way that I have proposed will make these accounts even more Rylean.

Elzinga's discussion of self-regulation, and Löwenstein's discussion of normative guidance, are both, in part, ways of trying to spell out what Ryle has in mind when he discusses the ‘responsib[ility]’ that is partly characteristic of the exercises of knowledge-how:

Appropriately, the above passage plays an important role in Elzinga's and Löwenstein's respective presentations of Ryle's view about knowledge-how (Löwenstein Reference Löwenstein2017: 32; Elzinga Reference Elzinga2018: 121). Ryle immediately elaborates:

As these remarks show, Elzinga is right to draw attention to self-regulation, and to learning from experience, in explicating the nature of such ‘intelligent’ or ‘responsible’ agency. Likewise, Löwenstein is right to draw our attention to the application of criteria in performance, and to the ways in which doing so makes agents responsible and their performances intelligent.

But also important to understanding the nature of intelligent or responsible agency is Ryle's paraphrase of self-regulation, and of the application of criteria, etc. as ‘thinking what [one] is doing while one is doing it, and thinking what [one] is doing in such a manner that [one] would not do the action so well if [one] were not thinking what [one] is doing’ (Ryle Reference Ryle2009 [1949]: 17–18).

Sax (Reference Sax2010: 519–20) observes that, in order to escape his own regress arguments, Ryle characterizes such application of criteria as the exercise of skill, or as the mindful exercise of certain abilities. But by going deeper into Ryle's characterization of the concept of mindful performance itself we can see how the specific amendment argued for in this paper is Rylean.Footnote ¹²

In a subsection of The Concept of Mind titled ‘Mental Occurrences,’ Ryle classifies the concept of thinking what one is doing as a ‘heed concept,’ or as a form of ‘minding’ (Ryle Reference Ryle2009 [1949]: 119). Inspecting and monitoring are special exercises of heed (Ryle Reference Ryle2009 [1949]: 119). Actions done with heed are actions that possess a ‘special character’:

That intelligent actions are actions done ‘while thinking what [one] is doing’ and that thinking what one is doing is acting with heed, and that acting with heed is undertaking an act that has a special character, fits nicely with Ryle's earlier claim that ‘adverbs expressing intelligence-concepts … signalize … that the performance itself possesses a certain style, method, or modus operandi’ (Ryle Reference Ryle1945: 3).

But what kind of ‘style, method, or modus operandi’ distinguishes intelligent actions from other kinds of actions? As it happens, Ryle doesn't say much about these styles and methods specifically (though his failure to do so is likely part and parcel of what Stout (Reference Stout2003: paras 15–18) calls Ryle's ‘nonreductive behaviorism’).Footnote ¹³ Even so, Ryle makes certain arguments about the logic of heed concepts. Specifically, in Mental Occurrences, Ryle argues that the logical profile of heed concepts makes the act-descriptions that employ them ‘semi-hypothetical,’ or ‘mongrel-categorical,’ statements (Ryle (Reference Ryle2009) [1949]: 124).

According to Ryle, semi-hypothetical statements are ‘at once narrative, explanatory and conditionally predictive, without being a conjunctive assemblage of detachable sub-statements’ ((2009) [1949]: 123). Allow me to break that down a bit. To describe a driver as driving carefully is to state categorically what the driver is doing, but in a way that also functions as an explanation of the very same act under a different description (e.g. that a particular driver is driving carefully explains this driver's looking over their right shoulder to check a blind spot, though these are not two different acts in the sense that we could ask which one was done first), and also licenses predictions about what the driver will or would do (e.g. that the driver is driving carefully licenses the prediction that, should the driver need to merge into the left lane, they will first look over their left shoulder to check the left-side blind spot) (cf. Ryle (Reference Ryle2009) [1949]: 125).Footnote ^14, Footnote ¹⁵

But to describe the driver as driving carefully is not to say, elliptically, several different things at once – a categorical report; an explanation of what is reported categorically; and a prediction of further occurrences. Rather, a semi-hypothetical statement is supposed to function in all of these ways at once (Ryle (Reference Ryle2009) [1949]: 123).Footnote ¹⁶

Part of Ryle's argument for the semi-hypothetical interpretation of heed concepts involves demystifying semi-hypotheticals, and this he does by arguing that they are ubiquitous in our everyday talk about non-mental phenomena (Ryle (Reference Ryle2009) [1949]: 124). For example, Ryle argues that ‘the sugar lump is dissolving’ and ‘the bird is migrating’ are both semi-hypothetical statements, and claims that most adduced examples of categorical statements are in fact semi-hypothetical statements (Ryle (Reference Ryle2009) [1949]: 124).

But here is where a number of Ryle's expositors seem to have missed an important part of Ryle's thesis.Footnote ¹⁷ As these expositors observe, Ryle's discussion often focuses on semi-hypotheticals like ‘the sugar lump is dissolving’ or ‘the bird is migrating’ or ‘you would miss the last train’ (Ryle (Reference Ryle2009) [1949]: 123–4). In these examples, the explanatory and predictive power of what is described semi-hypothetically is grounded in a standing tendency of the subject of the statement (or, perhaps, in the case of the migrating bird, in a telos). For example, the explanatory and predictive power of the fact that the sugar lump is dissolving (e.g. that the sugar lump is dissolving can explain why its sugar molecules are separating) is grounded in a stable, standing tendency of sugar to interact in a certain way with certain liquids.

Given this, one might be tempted to think that semi-hypothetical description is just a way of characterizing an event as the manifestation of a tendency for that kind of event to happen under certain conditions. This is what seems to be the case with ‘the sugar lump is dissolving,’ ‘you would miss the last train,’ and, on a certain (non-teleological) reading, ‘the bird is migrating.’

But this would be a mistake, for ‘Gilbert is driving carefully’ does not entail that Gilbert tends to drive carefully, or otherwise tends to do what careful drivers do.Footnote ¹⁸ Gilbert may now be driving carefully, despite his usual tendency to drive carelessly. Furthermore, ‘it is proper to order or request someone to apply his mind, as it is not proper to order him to be able or likely to do things’(Ryle (Reference Ryle2009) [1949]: 122). Still, the fact that (a usually careless) Gilbert is right now driving carefully has explanatory and predictive power (it may explain his now checking his blind spots, and license the prediction that he will modulate his speed in the near future if posted speed limits require it, etc.).

Since Gilbert can be driving carefully, despite his usual tendency to do otherwise, the explanatory and predictive power of the fact that he is driving carefully cannot, in general, be grounded in Gilbert's standing tendencies, but must instead be grounded (at least proximally) in a different ‘special character’ of his token driving performance, a special character that we indicate with an adverb of manner (viz ‘carefully’) (Ryle Reference Ryle2009 [1949]: 120–1).Footnote ^19, Footnote ²⁰

To recapitulate, Ryle's semi-hypothetical statements are statements that are supposed to indicate, categorically, that a certain kind of event is (or was, or will be) happening which in turn licenses certain explanations and predictions (Ryle Reference Ryle2009 [1949]: 123–5).Footnote ²¹ Some semi-hypothetical statements do this by characterizing an event as the manifestation of a tendency for that kind of event to happen (e.g. ‘the sugar lump is dissolving’ and ‘you would miss the last train’). But, crucially, other semi-hypothetical statements do this by instead adverting to a different ‘special character’ of the event itself, such as that adverted to by certain adverbs of manner (e.g. ‘Gilbert was driving carefully’). (This is the distinction that has often been overlooked by Ryle's expositors.) According to Ryle, though attributions of heed are, in general, semi-hypothetical statements of the second type, their logical profile is no more philosophically ‘scandalous’ than those of the first type (Ryle Reference Ryle2009 [1949]: 123).

As a heed concept, thinking what one is doing is evidently like φing carefully in that one can think what one is doing on a particular occasion despite a general tendency to perform absentmindedly. And even if one generally tends to perform absentmindedly, still, the fact that one is thinking what one is doing on a particular occasion will have explanatory and predictive power that is, according to Ryle, grounded (at least proximally) in a special character of the performance itself. So ‘Gilbert is thinking what he is doing while he is doing it’ is also a semi-hypothetical statement that adverts, not necessarily to any particular standing tendency of Gilbert's, but to some other non-etiological ‘special character’ of his performance.Footnote ²²

But what kind of ‘special character’ of Gilbert's performance is this? To find the answer, let us recall Ryle's earlier claim that ‘adverbs expressing intelligence-concepts … signalize … that the performance itself possesses a certain style, method, or modus operandi’ (Ryle Reference Ryle1945: 3) Though Ryle doesn't mention performance methods or styles explicitly in Mental Occurrences, methodological act-description (e.g. ‘solving the Rubik's cube using the Roux method’) would certainly qualify as semi-hypothetical: The fact that someone is using the Roux method could explain what they are doing under a different description (e.g. that they are now making a certain M move), and could license predictions about what they will or would do (e.g. that the last thing they will do is solve the Last Six Edges).

Consider again the second passage quoted in this section of the paper. Here, Ryle claims that the criteria for ascribing intelligence to an agent include the agent's satisfying and applying criteria, being ready to detect and correct lapses, being ready to repeat and improve upon successes, and profiting from examples when they are available (Ryle Reference Ryle2009 [1949]: 17–18). What's more, Ryle paraphrases an agent's meeting these criteria as the agent's thinking what [they are] doing in such a manner that [they] would not do the action so well if [they] were not thinking what [they are] doing (Ryle Reference Ryle2009 [1949]: 17–18).

A plausible interpretation now presents itself: The ‘special character’ of Gilbert's performance adverted to by ‘Gilbert is thinking what he is doing in such a manner that’ is ‘a certain style, method, or modus operandi’ (Ryle Reference Ryle1945: 3) characterizing Gilbert's performance that both explains and predicts (cf. Ryle Reference Ryle2009 [1949]: 125) his doing a number of finer-grained things in the course of performing in this way – satisfying and applying criteria, detecting and correcting lapses if need be, repeating and improving upon successes where possible, and profiting from the examples of others when they are available, etc. (cf. Ryle Reference Ryle2009 [1949]: 17–18).

This should remind the reader of the amendment to the views of Elzinga and Löwenstein that was proposed above. I proposed that Elzinga's self-regulation condition be understood as an ability to φ in a certain way, namely φing sensitively to the results of previous trials, etc.Footnote ²³ And, according to Ryle, ‘Gilbert is now φing sensitively to the results of previous trials’ is a heed-type semi-hypothetical statement which describes (in methodological or stylistic terms) a fact that can explain, for example, Gilbert's now repeating something that has worked for him in the past.

Similarly, I proposed that Löwenstein's normative guidance condition be understood as an ability to φ according to a certain method that includes, as a step, exercising a certain capacity for judgement. (Indeed, this is how Löwenstein, for the most part, already exposits their view.)Footnote ²⁴ Understood in this way, ‘Gilbert is φing in way w on the basis of his judgement that doing so is his best bet for meeting normative standards for φing under present conditions’ is also a heed-type semi-hypothetical statement which describes a fact that can explain, for example, Gilbert's φing in way w. Plausibly, both ‘Gilbert is φing sensitively the results of previous trials’ and ‘Gilbert is φing in way w on the basis of his judgement that …’ capture (at least part of) the heed-type semi-hypothetical content that Ryle would ascribe to ‘Gilbert is thinking what he is doing in such a way that …’

Gilbert's readiness to do these things equips him to cope with variation in the values of certain performance parameters. Consider Ryle's example of the intelligently performing mountaineer who, ‘walking over ice-covered rocks in a high wind in the dark … thinks what he is doing … [and as such] is ready for emergencies … economises in effort … makes tests and experiments’ etc. [italics mine] (Ryle Reference Ryle2009 [1949]: 30). Such a mountaineer knows how to mountaineer, and as such performs well under a variety of conditions in virtue of his ability to think what he is doing. But this variety of conditions under which the mountaineer can perform well do not so much define a set of possible worlds, since we don't know what the mountaineer needs to be ready to think what he is doing (e.g. coffee or no coffee). Rather, I propose that it is in virtue of his ability to think what he is doing in such a manner that … that the mountaineer is able to perform well given a variety of values for certain performance parameters, such as the presence or absence of hidden crevasses, more and less slippery surfaces, changes in wind strength, etc.

But even without knowing how robust the mountaineer's ability to think what he is doing is, still we can distinguish this mountaineer from the novice who must get lucky to perform well. For when someone is thinking what [they] are doing in such a manner that …, this fact has an explanatory and predictive power that the fact of a novice getting lucky does not have.

For example, the fact that an experienced bread baker is thinking what [they] are doing in such a manner that … could explain why they cover their dough before they let it rise, whereas the fact that a novice is getting lucky would not explain their covering the dough in the same way. That an experienced bread baker is thinking what [they] are doing in such a manner that … may license the prediction that they will add steam to the oven as necessary, whereas the fact that a novice is getting lucky does not license genuine predictions about what they will or would do under particular conditions.

If Ryle is right about this, then these differences show that our concept of what the experienced baker does (when they are thinking what they are doing in such a manner that … – i.e. when they are exercising their knowledge-how) is different from our concept of what the lucky novice does, and this even on the unlikely occasion when their performances are difficult to ‘photographically [or] gramophonically’ distinguish. For this reason, the novice cannot do what the experienced baker can do, even when the novice gets lucky. So an agent's ability to think what they are doing in such a manner that …, regardless of the enabling conditions that must be met if this agent is to exercise this ability (e.g. several cups of coffee; no coffee at all; the appeasement of personal superstitions; etc.), is enough to distinguish this agent from other agents who must get lucky if they are to φ in a standard-meeting way.

Nevertheless, doesn't Ryle commit himself to excluding cases of lucky success on the basis of the unreliability of luck? I don't believe that Ryle is committed to this. Consider again the first passage quoted in this section of the paper (viz. Ryle Reference Ryle2009 [1949]: 17). There, Ryle claims that when describing someone as knowing how to make jokes, fish, etc., we mean in part that ‘when they perform these operations, they tend to perform them well’ (Ryle Reference Ryle2009 [1949]: 17). This might seem to support reading Ryle as holding the view that knowing how to φ is, in part, constituted by a generally reliable ability to φ well. But I suggest that we instead read Ryle as claiming that when someone who knows how to φ uses this knowledge in the form of thinking what they are doing, they tend to perform well.Footnote ²⁵ This reading makes Ryle's view consistent with the plausible thesis that some people can only exercise certain knowledge-how under favorable conditions, including prior cups of coffee or the absence of certain kinds of psychological distress.

Further support for this reading can be found in Mental Occurrences, where Ryle considers an acquired capacity for meeting performance standards that does not issue in genuinely intelligent performances (Ryle Reference Ryle2009 [1949]: 129). Ryle claims that part of the difference between such a capacity and genuinely intelligent capacities lies in the fact that the latter are capacities for coping with certain kinds of variation. For example, a child:

In both of the above examples, the kind of variation Ryle mentions is what I have discussed earlier as variation in the values of certain performance parameters. The rock climber must be able to cope with variation in climbing challenges, but this isn't to say anything about what the rock climber requires to be ready to climb – two cups of coffee; or no coffee at all; etc.

8. How my amendment is Rylean

Above, I proposed an amendment to the views of Elzinga and Löwenstein respectively, according to which the second condition of their accounts (self-regulation in the case of Elzinga (Reference Elzinga2018: 132–8); normative guidance in the case of Löwenstein (Reference Löwenstein2017: §§1.4, 4.3, 4.4)) be understood as an ability to perform according to a certain method (or style). I proposed also that the first condition of these accounts be understood as an ability to reliably cope with certain variation in the values of certain performance parameters, and this in virtue of the method described in the second condition.

Amending these accounts in this way would make them more Rylean. This is because the Rylean self-regulation to which Elzinga appeals, and the Rylean normative guidance to which Löwenstein appeals, are both understood by Ryle as concepts for precisifying the ‘special character,’ or the ‘style, method, or modus operandi,’ of performances in which someone who knows how to φ uses this knowledge by thinking what they are doing in such a manner that they would not do the action so well if they were not thinking what they are doing.Footnote ²⁶
