Abstract
Pragmatic genealogies seek to explain ideas by regarding them, primarily, not as answers to philosophical questions, but as practical solutions to practical problems. Here I argue that pragmatic genealogies can inform the formation of philosophical canons. But the rationale for resorting to genealogy in this connection is not the familiar one that genealogy renders the concepts of the present intelligible by relating them to the concerns of the past—the claim is rather the reverse one, that genealogy renders the concepts of the past intelligible by relating them to the concerns of the present: past thinkers can be made to speak to us by revealing how their ideas tie in with our concerns, in the sense of helping us to remedy practical problems we still face in some form.
