Science my lad is made up of mistakes but they are mistakes which it is useful to make because they lead little by little to the truth.

Science is but an image of the truth.

The enlightenment is under threat. So is reason. So is truth. So is science especially in the schools of America.

The scientist is motivated primarily by curiosity and a desire for truth.

There is one thing even more vital to science than intelligent methods and that is the sincere desire to find out the truth whatever it may be.

In all science error precedes the truth and it is better it should go first than last.

The folly of mistaking a paradox for a discovery a metaphor for a proof a torrent of verbiage for a spring of capital truths and oneself for an oracle is inborn in us.

A scientific truth does not triumph by convincing its opponents and making them see the light but rather because its opponents eventually die and a new generation grows up that is familiar with it.

And the sad truth is that nobody wants me to write comedy. The Exorcist not only ended that career it expunged all memory of its existence.

The sad truth is that excellence makes people nervous.
