Albert Schweitzer on Mind

"The man who has become a thinking being feels a compulsion to give every will-to-live the same reverence for life that he gives to his own. He experiences that other life in his own."

"The thinking man must … oppose all cruel customs no matter how deeply rooted in tradition and surrounded by a halo. True manhood is too precious a spiritual good for us to surrender any part of it to thoughtlessness."

"From my youth onwards, I have felt sure that all thought which thinks itself out to an issue ends in mysticism. In the stillness of the African jungle I have been able to work out this thought and give it expression."

"The deepest thinking is humble. It is only concerned that the flame of truth which it keeps alive should burn with the strongest and purest heat; it does not trouble about the distance to which its brightness penetrates."

"There are two great fundamental problems common to all thought: the problem of world- and life-affirmation and world- and life-negation, and the problem of ethics and the relations between ethics and these two forms of man's spiritual attitude to Being."

"Example is not the main thing. It is the only thing. That is, if the one giving the example is not saying to himself, 'Behold I am giving an example.' That spoils it. Anyone thinking of the example he will give to others has lost his simplicity. Only as a man has simplicity can his example influence others."

"If rational thought thinks itself out to a conclusion, it arrives at something non-rational which, nevertheless, is a necessity of thought. This is the paradox which dominates our spiritual life. If we try to get on without this non-rational element, there result views of the world and of life which have neither vitality nor value."

"There slowly grew up in me an unshakable conviction that we have no right to inflict suffering and death on another living creature unless there is some unavoidable necessity for it, and that we ought all of us to feel what a horrible thing it is to cause suffering and death out of mere thoughtlessness. And this conviction has influenced me only more and more strongly with time. I have grown more and more certain that at the bottom of our heart we all think this, and that we fail to acknowledge it because we are afraid of being laughed at by other people as sentimentalists, though partly also because we allow our best feelings to get blunted. But I vowed that I would never let my feelings get blunted, and that I would never be afraid of the reproach of sentimentalism."
