Based at the University of St. Andrews, Arché was founded in 1998, with a mission to foster research of excellence on fundamental questions in analytical metaphysics, formal and philosophical logic, philosophy of language, philosophy of mathematics, and philosophy of mind. The Centre receives funding from the Arts and Humanities Research Council (AHRC) for several major research projects (some ongoing, some now completed): The Logical and Metaphysical Foundations of Classical Mathematics; The Grundgesetze Translation Project; The Metaphysics and Epistemology of Modality; and Vagueness: its Nature and Logic. The site carries detailed descriptions of these projects and invites philosophers to collaborate. Indeed, the centre is proud of its commitment to collaborative work, and regards itself as a focal point for scholars in the field. Information on fellowships, graduate studies and events are all available on the site, as is the Arché Twiki, a forum for discussion and exchange of ideas. Also provided are a small selection of podcasts, photographs and links to relevant websites.
