I prefer the company of animals more than the company of humans. Certainly, a wild animal is cruel. But to be merciless is the privilege of civilized humans.

At bottom God is nothing more than an exalted father.

It is unreasonable to expect science to produce a system of ethics-ethics are a kind of highway code for traffic among mankind-and the fact that in physics atoms which were yesterday assumed to be square are now assumed to be round is exploited with unjustified tendentiousness by all who are hungry for faith; so long as physics extends our dominion over nature, these changes ought to be a matter of complete indifference to you.

A strong egoism is a protection.

Religion is an attempt to get control over the sensory world, in which we are placed, by means of the wish-world, which we have developed inside us as a result of biological and psychological necessities... If one attempts to assign to religion its place in man's evolution, it seems not so much to be a lasting acquisition, as a parallel to the neurosis which the civilized individual must pass through on his way from childhood to maturity.

If all the evidence put forward for the authenticity of religious teachings originates in the past, it is natural to look round and see whether the present, about which it is easier to form judgements, may not also be able to furnish evidence of the sort. If by this means we could succeed in clearing even a single portion of the religious system from doubt, the whole of it would gain enormously in credibility.

The dream acts as a safety-valve for the over-burdened brain.
