No Amount Of Experimentation Can Ever Prove Me

I never made one of my discoveries through the process of rational thinking

It is only prudent never to place complete confidence in that by which we have even once been deceived.

Anyone who has never made a mistake has never tried anything new.

The only sure way to avoid making mistakes is to have no new ideas.

I cannot teach anybody anything. I can only make them think.

You can never solve a problem on the level on which it was created.
