I have not the slightest confidence in 'spiritual manifestations.'

There are some truths, however, that we should never forget: Superstition has always been the relentless enemy of science; faith has been a hater of demonstration; hypocrisy has been sincere only in its dread of truth, and all religions are inconsistent with mental freedom.

If this religion is true, then there is only one Savior, only one narrow path to life. Christianity cannot live in peace with any other religion.

A good deed is the best prayer.

Every church that has a standard higher than human welfare is dangerous.

Small people delight in what they call consistency-that is, it gives them immense pleasure to say that they believe now exactly as they did ten years ago. This simply amounts to a certificate that they have not grown-that they have not developed-and that they know just as little now as they ever did. The highest possible conception of consistency is to be true to the knowledge of today, without the slightest reference to what your opinion was years ago.

Heresy is a cradle; orthodoxy a coffin.
