Friedrich Nietzsche on emotion

Blessed are the forgetful: for they get the better even of their blunders.

A few hours of mountain climbing turn a villain and a saint into two rather equal creature. Exhaustion is the shortest way to equality and fraternity, and liberty is added eventually by sleep.

What is happiness? The feeling that power is growing, that resistance is overcome.

Mankind are governed more by their feelings than by reason.

Samuel Adams1722–1803Letter to Samuel Cooper (30 April 1776)

I am very conscious of the fact that our feelings and strivings are often contradictory and obscure and that they cannot be expressed in easy and simple formulas.

Albert Einstein1879–1955Why Socialism? (1949)

Never apologize for showing feeling, my friend. Remember that when you do so, you apologize for truth.

Benjamin Disraeli1804–1881Contarini Fleming (1832), Part 1, Chapter 13
