This volume gathers together selected symposium papers presented at the Philosophy of Science Association Meeting, held in Chicago on November 6–9, 2014. Fifty-five symposium proposals were submitted for the meeting, from which 30 (54%) were selected—leading to roughly 120 papers presented in symposia. This volume includes the 40 papers chosen by the program committee, organized by symposia, along with Helen Longino’s presidential address.

It is a pleasure to thank the many individuals who have helped bring this volume to press. First, I must thank the members of the program committee, whom I relied on heavily throughout this entire process:

The committee persevered through a heavier-than-expected workload for this meeting, because of higher rates of submission, with surprisingly good spirits. I cannot thank them enough for the integrity and good judgment they exercised throughout.

My approach to this job was shaped by my stint on the PSA 2012 program committee, chaired by the inimitable Andrea Woody. As well as being an exemplary chair, Andrea provided thorough, effective advice throughout my tenure, and it is a pleasure to thank her for her generous assistance. I also gratefully acknowledge help from Steve Downes, program chair for PSA 2010. Several colleagues helped to identify potential members of the program committee. I will not list their names here, for fear that the committee members may not share my gratitude.

Jessica Pfeifer deserves nearly all the credit for creating such a stimulating meeting out of the raw materials selected by the program committee. Her expert management belies the fact that this was her first PSA meeting as executive secretary. I am enormously grateful for her help and guidance, which kept my job manageable. I am also grateful for assistance from Gary Hardcastle, the PSA’s previous executive secretary, and from our colleagues at the History of Science Society, especially Jay Malone and Greg Macklem.

Philosophy of Science’s editorial team has been indispensable. Jeff Barrett has assembled and led a great editorial team, and it has been a pleasure to work with them both as an associate editor for the journal and in my role as program chair. I am immensely grateful to Jeff for his advice and support. The managing editors I have worked with have insulated me from the complexities of the editorial software and dealings with the press. I am grateful to Hannah Rubin, who handled the earlier stages of my work as program chair and the Contributed Papers volume, and to Sarita Rosenstock, whose editorial support for this volume has been terrific.

The PSA Governing Board provided financial support that allowed me to have a reduced teaching load while serving as program chair. I am grateful to Michael Milde, Dean of Arts and Humanities, and Henrik Lagerlund, Chair of the Department of Philosophy, for their support. In addition to the teaching release, I was able to hire an undergraduate work-study student to assist with several time-consuming tasks.

It is a pleasure to thank Helen Longino and the Governing Board of the PSA for the opportunity to play this role. It has been fascinating to see the breadth of research being pursued by the members of the PSA and rewarding to interact with scholars from across the discipline. My final thanks goes to those who submitted symposium proposals and papers. The quantity and quality of the contributions made the deliberations of the program committee all that much more difficult, but they reflect a growing and thriving scholarly community.
