Essentialism logically entails necessary-and-sufficient condition concept structure

Evidence

An intimate bond links the necessary and suf- ficient condition structure to essentialism. If some characteristic is essential for an animal to be a human being, then that characteristic is a necessary condition for being human. — Gary Goertz, Social Science Concepts, 148

Categorization

• DEFINE: Explains why a philosophical commitment (essentialism) mechanically forces a specific concept structure (necessary and sufficient conditions).
• DEEPTHINKING: Unpacks the hidden entailment behind ‘standard’ concept definition — most people treat necessary-and-sufficient conditions as a neutral default rather than the downstream consequence of a metaphysical stance about essences.
