Science built the Academy, superstition the Inquisition.

Every flower about a house certifies to the refinement of somebody. Every vine climbing and blossoming tells of love and joy

There is no necessity for going to the church and hearing the same story forever. Let the minister write what he wishes to say. Let him publish it. If it is worth buying, people will read it. It is hardly fair to get them in a church in the name of duty and there inflict upon them a sermon that under no circumstances they would read...the idea of going fifty-two days in a year to hear anybody on the same subject is absurd.

Give any orthodox church the power, and to-day they would punish heresy with whip, and chain, and fire. As long as a church deems a certain belief essential to salvation, just so long it will kill and burn if it has the power.

Upon the great questions of origin, of destiny, of immortality, of . . . other worlds, every honest man must say, 'I do not know.' Upon these questions, this is the creed of intelligence.

The intellectual advancement of man depends on how often he can exchange an old superstition for a new truth.

It seems to me impossible for a civilized man to love or worship, or respect the God of the Old Testament. A really civilized man, a really civilized woman, must hold such a God in abhorrence and contempt... In the New Testament, death is not the end, but the beginning of punishment that has no end. In the New Testament the malice of God is infinite and the hunger of his revenge eternal... This frightful dogma, this infinite lie, made me the implacable enemy of Christianity. The truth is that this belief in eternal pain has been the real persecutor.
