[filed under theme 13. Knowledge Criteria / C. External Justification / 2. Causal Justification ]

Full Idea

With the psychological conception of logic we lose the distinction between the grounds that justify a conviction and the causes that actually produce it.

Gist of Idea

Psychological logic can't distinguish justification from causes of a belief

A Reaction

Thus Frege kicked the causal theory of justification well into touch long before it had even been properly formulated. That is not to say that there is no psychological aspect to logic, because there is.
