An atheist is a man who watches a Notre Dame - Southern Methodist University game and doesn't care who wins.

It seems to me absurd to doubt that a man may be an ardent Theist and an evolutionist. ... I have never been an atheist in the sense of denying the existence of a God.

A man cannot become an atheist merely by wishing it.

I have never seen the slightest scientific proof of the religious ideas of heaven and hell, of future life for individuals, or of a personal God.

The abolition of religion as the illusory happiness of the people is the demand for their real happiness.

Since only what is material is perceptible, knowable, nothing is known of the existence of God.
