4. Expression and Analogy in Leibniz’s Philosophy

Valérie Debuiche


Expression is one of the most famous concepts used by Leibniz throughout his life. But this concept is as frequently employed as it is rarely explained, even if it is often illustrated by the metaphor of geometrical perspective or conical projection. This text presents expression as an analogy between the relations of two things, one said ‘expressing’ and the other ‘expressed.’ It addresses the subsequent questions about what kind of analogy expression is supposed to be, which relations are involved and what is the nature of their analogy. It will be defended here that the expressive analogy pertains to a kind of (imperfect) identity rather than to the more classical idea of similarity illustrated by the geometrical example of perspective.
