Never floss with a stranger.

My definition of an intellectual is someone who can listen to the William Tell Overture without thinking of the Lone Ranger.

In those early years in New York when I was a stranger in a big city it was the companionship and later friendship which I was offered in the Linnean Society that was the most important thing in my life.

If I am outspoken of the dangers of intemperance to members of our armed forces it is because we are all especially concerned for the welfare of those who are risking their lives in the cause of freedom.

I know what you're going to say! 'They are men and men should be free.' A free man is dangerous to himself and everyone else. Freedom should be left to those who can put it to good use.

The three main sources of scepticism are first that not every people desires freedom second that democracy in certain parts of the world would be dangerous and third that there is little the world's democracies can do to advance freedom outside their countries.

Men like me who merely wish to establish political freedom will in such circumstances lose all their influence and others will get influence who may become dangerous to all established interests whatsoever.

Israel was born under the British mandate. We learned from the British what democracy means and how it behaves in a time of danger war and terror. We thank Britain for introducing freedom and respect of human rights both in normal and demanding circumstances.

Freedom of conscience entails more dangers than authority and despotism.
