Euclid's Elements

THE HISTORICAL RECORD  ·  c. 300 BC  ·  Near-East

Home › Timeline › The Prophets and the Road › Euclid's Elements

Euclid's Elements. Grant the postulates and the conclusions are forced; anyone who can follow the steps can catch an error without permission from anybody.

In plain words

Euclid's Elements: grant the starting assumptions and every conclusion follows, and anyone who can follow the steps can catch a mistake without anyone's permission: the first authority that hands you the means to overturn it.

The mechanism

THE FIRST AUTHORITY THAT HANDS YOU THE MEANS TO OVERTURN IT — no oracle, no king's seal, no appeal to what the temple holds
