Ethical teaching is weakened if it is tied up with dogmas that will not bear examination.

This hideous doctrine of eternal torment after death has probably caused more terror and misery, more cruelty and more violation of natural human sympathy, than any belief in the history of mankind. Yet this doctrine was taught unambiguously by Jesus.

One of the best ways to improve men's behaviour is to enlighten their minds: and today, against the strong opposition of the Church and the Establishment, Scientific Humanism is attempting to do just that.

It is difficult, none the less, for the ordinary man to cast off orthodox beliefs, for he is seldom allowed to hear the other side... Whereas the Christian view is pressed on him day in and day out.

There is no justification for the common claim that Christianity was responsible for the abolition of slavery. The Negro slave trade - a far more infamous practice than slavery in the ancient world - was initiated, carried on and defended by Christian men in Christian countries.

Jesus, in fact, was typical of a certain kind of fanatical young idealist: at one moment holding forth, with tears in his eyes, about the need for universal love at the next, furiously denouncing the morons, crooks and bigots who did not see eye to eye with him. It is very natural and very human behaviour. But it is not superhuman.

I was convinced that, besides millions of frank unbelievers, there are today large numbers of half-believers to whom religion is a source of intellectual and moral discomfort.
