I always felt that a scientist owes the world only one thing, and that is the truth as he sees it.

Tact and diplomacy are fine in international relations, in politics, perhaps even in business; in science only one thing matters, and that is the facts.

If the truth contradicts deeply held beliefs, that is too bad.

The only thing an actor owes his public is not to bore them.

The one thing I have always felt about musical theatre is that it is, to an extraordinary degree, about construction.

God only made one thing in this world that's perfect - and that's my boxing record.
