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

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.

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.

Deception is mostly a game we play with ourselves.

A lie's true power cannot be accurately measured by the number of people who believe its deception when it is told, it must be measured by the number of people who will go out after hearing it trying to convince others of its truth.

A truth is what it is. A lie, a thought out deception more brutal than a truth could ever be.
