“Kindness is strength. Good-nature is often mistaken for virtue, and good health sometimes passes for genius. Anger blows out the lamp of the mind. In the examination of a great and important question, every one should be serene, slow-pulsed, and calm. Intelligence is not the foundation of arrogance. Insolence is not logic. Epithets are the arguments of malice.”

“Anger is the wind which blows out the lamp of the mind.”

“In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.”

“Neither exhortations to virtue nor the argument of approaching death should divert us from literature; for in a good mind it excites the love of virtue, and dissipates, or at least diminishes, the fear of death.”

“It is great good health to believe as the Hindus do that there are 33 million gods and goddesses in the world. It is great good health to want to understand one s dreams. It is great good health to desire the ambiguous and paradoxical. It is sickness of the profoundest kind to believe that there is one reality. There is sickness in any piece of work or any piece of art seriously attempting to suggest that the idea that there is more than one reality is somehow redundant.”

“Men are apt to mistake the strength of their feeling for the strength of their argument. The heated mind resents the chill touch and relentless scrutiny of logic.”
