Full Idea
Aristotle's way with axioms, rather than Euclid's, is as assumptions which we are willing to agree on while awaiting an opportunity to prove them
Gist of Idea
Aristotle's axioms (unlike Euclid's) are assumptions awaiting proof

A Reaction
Euclid's are understood as basic self-evident truths which will be accepted by everyone, though the famous parallel line postulate undermined that. The modern view of axioms is a set of minimum theorems that imply the others. I like Aristotle.
