The dreams we imagine when we are asleep should not in any way make us doubt the truth of the thoughts we have when we are awake.

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

And thus, the actions of life often not allowing any delay, it is a truth very certain that, when it is not in our power to determine the most true opinions we ought to follow the most probable.

If you would be a real seeker after truth, it is necessary that at least once in your life you doubt, as far as possible, all things.

You just keep pushing. You just keep pushing. I made every mistake that could be made. But I just kept pushing.

There is nothing more ancient than the truth.
