I do not see how astronomers can help feeling exquisitely insignificant, for every new page of the Book of the Heavens they open reveals to them more and more that the world we are so proud of is to the universe of careening globes as is one mosquito to the winged and hoofed flocks and herds that darken the air and populate the plains and forests of all the earth. If you killed the mosquito would it be missed? Verily, What is Man, that he should be considered of God?

My experience with horses is that they never throw away a chance to go lame.

The easy confidence with which I know another man's religion is folly teaches me to suspect that my own is also. I would not interfere with any one's religion, either to strengthen it or to weaken it. I am not able to believe one's religion can affect his hereafter one way or the other, no matter what that religion may be. But it may easily be a great comfort to him in this life-hence it is a valuable possession to him.

You want to be very careful about lying; otherwise you are nearly sure to get caught.

The laws of Nature, that is to say the laws of God, plainly made every human being a law unto himself, we must steadfastly refuse to obey those laws, and we must as steadfastly stand by the conventions which ignore them, since the statutes furnish us peace, fairly good government, and stability, and therefore are better for us than the laws of God, which would soon plunge us into confusion and disorder and anarchy if we should adopt them.

I am aware that I am very old now; but I am also aware that I have never been so young as I am now, in spirit, since I was fourteen and entertained Jim Wolf with the wasps. I am only able to perceive that I am old by a mental process; I am altogether unable to feel old in spirit. It is a pity, too, for my lapses from gravity must surely often be a reproach to me. When I am in the company of very young people I always feel that I am one of them, and they probably privately resent it.

What God lacks is convictions- stability of character. He ought to be a Presbyterian or a Catholic or something- not try to be everything.
