[filed under theme 12. Knowledge Sources / A. A Priori Knowledge / 2. Self-Evidence ]

Clarification

A 'will-o'-the-wisp' deceives you and leads you astray

Self-evidence is often a mere will-o'-the-wisp

A Reaction

The sort of nice crisp remark you would expect from a good empiricist philosopher. Compare Idea 4948. However Russell qualifies it with the word 'often', and all philosophers eventually realise that you have to start somewhere.
