Steven Weinberg – Dreams of a Final Theory (1993)

by vyh

Electrons are an essential part of our everyday world; the particles called muons and tauons hardly matter at all to our lives; yet, in the way that they appear in our theories, electrons do not seem in any way more fundamental than muons and tauons. More generally, no one has ever discovered any correlation between the importance of anything to us and its importance in the laws of nature.

(quoted in The Portable Atheist)
