Single Idea 6938

[catalogued under 27. Natural Reality / G. Biology / 3. Evolution]

Full Idea

It is probably of more advantage to an animal to have his mind filled with pleasing and encouraging visions, independently of their truth; and thus, upon unpractical subjects, natural selection might occasion a fallacious tendency of thought.

Gist of Idea

Natural selection might well fill an animal's mind with pleasing thoughts rather than true ones

A Reaction

Note that this is a pragmatist saying that a set of beliefs might work fine but be untrue. So Peirce does not have the highly relativistic notion of truth of some later pragmatists. Good for him. Note the early date to be thinking about Darwin.
