Overview
Academic Skepticism emerged within Plato's Academy under Arcesilaus and Carneades and challenged the Stoic claim that some impressions guarantee their own truth. Carneades developed graded persuasive impressions to show how inquiry and action could proceed without a Stoic criterion of certainty. Ancient reports and modern interpreters disagree over whether he endorsed this account himself or offered it dialectically against the Stoics.
Key ideas
- Against the Stoic Criterion: Academic arguments deny that any sense-impression carries the self-guaranteeing mark of truth claimed by the Stoics. On a dialectical reading, these arguments expose consequences of Stoic premises without stating the Academics' own doctrine.
- Persuasive Impressions: Carneades distinguished grades of persuasiveness and described how a person could examine and act on the strongest impressions. Whether this was his own doctrine or a dialectical reply to the Stoics is disputed.
- Dialectical Method: The Academic Skeptics argued against every position without committing to any — using opponents' premises to generate contradictions.

Positions held
- Academic Fallibilism
Carneades developed the persuasive-impression criterion in reply to Stoic objections that skepticism made action impossible. Whether he endorsed it as his own doctrine or advanced it dialectically remains disputed.
