Single Idea 2255

[catalogued under 13. Knowledge Criteria / B. Internal Justification / 4. Foundationalism / a. Foundationalism]

Full Idea

Archimedes sought but one firm and immovable point in order to move the entire earth. Just so, great things are to be hoped for if I succeed in finding just one thing, however slight, that is certain and unshaken.

Gist of Idea

Only one certainty is needed for progress (like a lever's fulcrum)

A Reaction

The classic foundationalist difficulty is that you may find something totally certain, but is it a fulcrum? Or is it just minimal, boring and useless?
