“Nature is relentless and unchangeable, and it is indifferent as to whether its hidden reasons and actions are understandable to man or not.”

See now the power of truth.

In my studies of astronomy and philosophy I hold this opinion about the universe, that the Sun remains fixed in the centre of the circle of heavenly bodies, without changing its place; and the Earth, turning upon itself, moves round the Sun.

Who would dare assert that we know all there is to be known?

It is surely harmful to souls to make it a heresy to believe what is proved.

Knowing thyself, that is the greatest wisdom.

Philosophy is written in that great book which ever lies before our eyes. I mean the universe, but we cannot understand it if we do not first learn the language and grasp the symbols, in which it is written.

We cannot teach people anything; we can only help them discover it within themselves.

Holy Scripture could never lie or err…its decrees are of absolute and inviolable truth.

I believe in justice, and I believe in people being held responsible for their actions.

The cynic puts all human actions into two classes – openly bad and secretly bad.

Life does not consist in thinking, it consists in acting.

If anybody knows how to make action movies it’s Sly.

I just have more fun when I get to try new things – and the action film genre has kind of painted itself into a corner, copied itself so many times and it has basically run out of bad buys.

Jefferson’s Declaration of Independence is a practical document for the use of practical men. It is not a thesis for philosophers, but a whip for tyrants; it is not a theory of government but a program of action.
