Definitions and axioms in first-order logic must be kept separate from each other: the definition of a term x is designed to be the shortest and logically simplest specification of necessary and sufficient conditions for being and instance of x. The axioms specify additional distinguishing marks which are seen as holding for all such instances. The advantages of this strategy are: 1. definitions are easy to understand and easy to apply, 2. definitions are more stable in the sense that new kinds of x might be discovered, or might evolve, which falsify one or other axiom, but still satisfy the definition.

Definitions and axioms in first-order logic must be kept separate from each other: the definition of a term x is designed to be the shortest and logically simplest specification of necessary and sufficient conditions for being and instance of x. The axioms specify additional distinguishing marks which are seen as holding for all such instances. The advantages of this strategy are: 1. definitions are easy to understand and easy to apply, 2. definitions are more stable in the sense that new kinds of x might be discovered, or might evolve, which falsify one or other axiom, but still satisfy the definition.
