Science is essentially an anarchic enterprise: theoretical anarchism is more humanitarian and more likely to encourage progress than its law-and-order alternatives.

So far Unitarian realism claiming to possess positive knowledge about Ultimate Reality has succeeded only by excluding large areas of phenomena or by declaring, without proof, that they could be reduced to basic theory, which, in this connection, means elementary particle physics.

No single theory ever agrees with all the facts in its domain

Humane science must be adapted to the requirements of a balanced and rewarding life.

Without a constant misuse of language there cannot be any discovery, any progress

Arguments hardly affect the faithful- their beliefs have an entirely different foundation.

Given any rule, however �fundamental� or �necessary� for science, there are always circumstances when it is advisable not only to ignore the rule, but to adopt its opposite.
