Mark Twain

Thou shalt not commit adultry is a command which makes no distinction between the following persons. They are all required to obey it: children at birth. Children in the cradle. School children. Youths and maidens. Fresh adults. Older ones. Men and women of 40. Of 50. Of 60. Of 70. Of 80. Of 100. The command does not distribute its burden equally, and cannot. It is not hard upon the three sets of children.

Evolution is the law of policies: Darwin said it, Socrates endorsed it, Cuvier proved it and established it for all time in his paper on The Survival of the Fittest.

Of what use, however, is a general certainty that an insect will not walk with his head hindmost, when what you need to know is the play of inward stimulus that sends him hither and thither in a network of possible paths?

The search after the great men is the dream of youth, and the most serious occupation of manhood.

The most fatal disease of friendship is gradual decay, or dislike hourly increased by causes too slender for complaint, and too numerous for removal.

Life too near paralyses art.

The surest poison is time.

I have no doubt that it is a part of the destiny of the human race, in its gradual improvement, to leave off eating animals, as surely as the savage tribes have left off eating each other when they came in contact with the more civilized.

Any 20 year-old who isn’t a liberal doesn’t have a heart, and any 40 year-old who isn’t a conservative doesn’t have a brain.

Avoid flatterers, for they are thieves in disguise.

All endeavor calls for the ability to tramp the last mile, shape the last plan, endure the last hours toil. The fight to the finish spirit is the one… characteristic we must posses if we are to face the future as finishers.

Never mistake knowledge for wisdom. One helps you make a living; the other helps you make a life.
