Dominique Pagani starts from etymology: "definition" contains "finish". A definition therefore comes at the end of the analysis, not at the beginning1. He takes up Aristotle's formula: to define is to give the proximate genus and the specific difference. He sees in it two contradictory operations, stating what is common and then what is proper, including and excluding2. The example of the cheetah and the platypus shows that the formula is not always easy to apply. He brings definition and determination together: to define is to limit a thing on the basis of something else. Thus a table is defined by its function rather than by its shape or its material3. For him, concepts are like elastic bands that must be tightened. Clarifying a term means distinguishing it from what resembles it4. He also notes that a science is defined by its object, but does not itself define that object. In 2021, he specifies that a definition does not fix a definitive point of view: it serves to agree on the meaning of words5. In 2026, he places the question "what do you call…?" at the heart of philosophy.
