The Wise Club reconstructs the collaborative intellectual culture in which the Scottish philosophy of common sense first emerged in the Aberdeen Philosophical Society between 1758 and 1773. Rather than attributing this school of thought to a single founder, the study traces how David Skene, John Gregory, Thomas Reid, George Campbell, Alexander Gerard, and James Beattie developed distinct yet compatible inquiries across different branches of knowledge through a disciplined culture of inquiry. Their collective commitment to an inductive investigation of the original faculties of the human mind extended common sense beyond epistemology to natural history, medicine, rhetoric, aesthetics, moral philosophy, and imaginative literature. Drawing on unpublished discourses, abstracted discussions, lecture notes, and correspondence, this Element situates the Wise Club in a formative context that produced canonical works of the Scottish Enlightenment and reinterprets common sense philosophy as a characteristic method of inquiry rather than a unified doctrinal system.
