[filed under theme 13. Knowledge Criteria / B. Internal Justification / 4. Foundationalism / d. Rational foundations ]

Full Idea

I possess a standard enabling me to judge presentations to be true when they have a character of a sort that false ones could not have.

Gist of Idea

A presentation is true if we judge that no false presentation could appear like it

Source

report of Zeno (Citium) (fragments/reports [c.294 BCE]) by M. Tullius Cicero - Academica II.18.58

Book Ref

Cicero: 'De Natura Deorum and Academica (XIX)', ed/tr. Rackham,H. [Harvard Loeb 1933], p.541


A Reaction

[This is a spokesman in Cicero for the early Stoic view] No sceptic will accept this, but it is pretty much how I operate. If you see something weird, like a leopard wandering wild in Hampshire, you believe it once you have eliminated possible deceptions.
