Man is a rational animal. So at least we have been told. Throughout a long life I have searched diligently for evidence in favor of this statement. S… - Bertrand Russell

Science does not aim at establishing immutable truths and eternal dogmas; its aim is to approach the truth by successive approximations, without claiming that at any stage final and complete accuracy has been achieved.

We used to think that Hitler was wicked when he wanted to kill all the Jews, but what Kennedy and Macmillan and others both in the East and in the West pursue policies which will probably lead to killing not only all the Jews but all the rest of us too. They are much more wicked than Hitler and this idea of weapons of mass extermination is utterly and absolutely horrible and it is a thing which no man with one spark of humanity can tolerate and I will not pretend to obey a government which is organising the massacre of the whole of mankind. I will do anything I can to oppose such Governments in any non-violent way that seems likely to be fruitful, and I should exhort all of you to feel the same way. We cannot obey these murderers. They are wicked and abominable. They are the wickedest people that ever lived in the history of man and it is our duty to do what we can.

There's a Bible on that shelf there. But I keep it next to Voltaire – poison and antidote.
