The longing to behold this pre-established harmony [of phenomena and theoretical principles] is the source of the inexhaustible patience and perseverance with which Planck has devoted himself ... The state of mind which enables a man to do work of this kind is akin to that of the religious worshiper or the lover; the daily effort comes from no deliberate intention or program, but straight from the heart.
The moral sense reappears today with the same morning newness that has been from of old the fountain of beauty and strength. You say there is no religion now. 'Tis like saying in rainy weather, There is no sun, when at that moment we are witnessing one of its superlative effects.
Religions contradict one another-on small matters, such as whether we should put on a hat or take one off on entering a house of worship, or whether we should eat beef and eschew pork or the other way around, all the way to the most central issues, such as whether there are no gods, one God, or many gods.
There is really no way we can know the heart, the intentions, or the circumstances of someone who might say or do something we find reason to criticize. Thus the commandment: 'Judge not.'
Religious literature has eminent examples, and if we run over our private list of poets, critics, philanthropists and philosophers, we shall find them infected with this dropsy and elephantiasis, which we ought to have tapped.
I think that if anything can be proved by natural theology, it is that slavery is morally wrong. God gave man a mouth to receive bread, hands to feed it, and his hand has a right to carry bread to his mouth without controversy.
And if a person is religious, I think it's good, it helps you a bit. But if you're not, at least you can have the sense that there is a condition inside you which looks at the stars with amazement and awe.
Thus it is well to seem merciful, faithful, humane, sincere, religious, and also to be so; but you must have the mind so disposed that when it is needful to be otherwise you may be able to change to the opposite qualities.
Science not only purifies the religious impulse of the dross of its anthropomorphism but also contributes to a religious spiritualization of our understanding of life.
Men have looked away from themselves and at things so long that they have come to esteem the religious, learned and civil institutions as guards of property, and they deprecate assaults on these, because they feel them to be assaults on property. They measure their esteem of each other by what each has, and not by what each is.
The energetic action of the times develops individualism, and the religious appear isolated. I esteem this a step in the right direction. Heaven deals with us on no representative system. Souls are not saved in bundles.
Therefore it is unnecessary for a prince to have all the good qualities I have enumerated, but it is very necessary to appear to have them. And I shall dare to say this also, that to have them and always to observe them is injurious, and that to appear to have them is useful; to appear merciful, faithful, humane, religious, upright, and to be so, but with a mind so framed that should you require not to be so, you may be able and know how to change to the opposite.
