A believer is a bird in a cage, a freethinker is an eagle parting the clouds with tireless wing.

The Catholics have a Pope. Protestants laugh at them, and yet the Pope is capable of intellectual advancement. In addition to this, the Pope is mortal, and the church cannot be afflicted with the same idiot forever. The Protestants have a book for their Pope. The book cannot advance. Year after year, and century after century, the book remains as ignorant as ever.

The only thing that makes life endurable in this world is human love, and yet, according to Christianity, that is the very thing that we are not to have in the other world. We are to be so taken up with Jesus and angels, that we shall care nothing about our brothers and sisters that have been damned. We shall be so carried away with the music of the harp that we shall not even hear the wail of father and mother. Such a religion is a disgrace to human nature.

To be like other people is to be unlike ourselves.
