“For tolerance (and you must remember this when you grow older), is of very recent origin and even the people of our own so-called "modern world" are apt to be tolerant only upon such matters as do not interest them very much.”

“The worst surroundings in the world can be tolerated if the people in them are interesting and kind.”

“Tolerance, which is one form of love of neighbor, must manifest itself not only in our personal relations, but also in the arena of society as well. In the world of opinion and politics, tolerance is that virtue by which liberated minds conquer the evils of bigotry and hatred. Tolerance implies more than forbearance or the passive enduring of ideas different from our own. Properly conceived, tolerance is the positive and cordial effort to understand another’s beliefs, practices, and habits without necessarily sharing or accepting them. Tolerance quickens our appreciation and increases our respect for our neighbor’s point of view. It goes even further; it assumes a militant aspect when the rights of an opponent are assailed. Voltaire’s dictum, “I do not agree with a word that you say, but I will defend to the death your right to say it,” is for all ages and places the perfect utterance of the tolerant ideal.”

“When you come across with the ideas that you don’t like and even hate, do these three things: Be tolerant, be tolerant and be tolerant! Let them speak! Let the stupid and even the fools speak! Protecting freedom of expression under every circumstance is an honour for a man!”

“Antinerd and antigeek prejudices are tolerated because they are seen as harmless, but they are not. They are bad for children, and they might be bad for our society as a whole, because they are recent incarnations of a very old American disease: anti-intellectualism. And anti-intellectualism, as I will argue, is very bad for children and even worse for our society as a whole.”

“When you make a world tolerable for yourself, you make a world tolerable for others.”
