Single Idea 20795

[filed under theme 13. Knowledge Criteria / B. Internal Justification / 4. Foundationalism / b. Basic beliefs ]

Full Idea

Dogmatists say something can be its own criterion. The straight is the standard of itself, and a set of scales establishes the equality of other things and of itself, and light seems to reveal not just other things but also itself.

Gist of Idea

Some things are their own criterion, such as straightness, a set of scales, or light
