Full Idea
The so-called Empiricists in Hellenistic times [as cited by Galen] denied the existence of reason, treating it as a useless theoretical postulate introduced by some philosophers
Gist of Idea
Early empiricists said reason was just a useless concept introduced by philosophers
Source
report of Galen (An Outline of Empiricism [c.170], 87.4-9.28ff) by Michael Frede - Intro to 'Rationality in Greek Thought' p.3
Book Ref
'Rationality in Greek Thought', ed/tr. Frede,M /Striker,G [OUP 1999], p.3
A Reaction
I think 'be sensible' is understood by everyone, but 'use your reason' is far from obvious. The main role of reason seems to be as an identifier for human exceptionalism. Animals obviously make good judgements. Frede thinks the empiricists were right.
