I do not believe in loving enemies; I have pretty hard work to love my friends.

Injustice upon earth renders the justice of of heaven impossible.

Spirituality for the most part is a mask worn by idleness, arrogance and greed.

Man must learn to rely upon himself. Reading bibles will not protect him from the blasts of winter, but houses, fires. and clothing will. To prevent famine, one plow is worth a million sermons, and even patent medicines will cure more diseases than all the prayers uttered since the beginning of the world.

All that is necessary, as it seems to me, to convince any reasonable person that the Bible is simply and purely of human invention - of barbarian invention - is to read it. Read it as you would any other book; think of it as you would of any other; get the bandage of reverence from your eyes; drive from your heart the phantom of fear; push from the throne of your brain the cowled form of superstition - then read the Holy Bible, and you will be amazed that you ever, for one moment, supposed a being of infinite wisdom, goodness and purity, to be the author of such ignorance and of such atrocity.

In the search for truth - that everything in nature seems to hide - man needs the assistance of all his faculties. All the senses should be awake.

I believe that there is something far nobler than loyalty to any particular man. Loyalty to the truth as we perceive it - loyalty to our duty as we know it - loyalty to the ideals of our brain and heart - is, to my mind, far greater and far nobler than loyalty to the life of any particular man or God. . . .
