The only sin is limitation. As soon as you once come up with a man's limitations, it is all over with him. Has he talents? has heenterprise? has he knowledge? It boots not. Infinitely alluring and attractive was he to you yesterday, a great hope, a sea to swim in; now, you have found his shores, found it a pond, and you care not if you never see it again.
Genius detects through the fly, through the caterpillar, through the grub, through the egg, the constant individual; through countless individuals the fixed species; through many species the genus; through all genera the steadfast type; through all the kingdoms of organized life the eternal unity.
