Human beings seem to have an almost unlimited capacity to deceive themselves, and to deceive themselves into taking their own lies for truth.

You can fool some of the people all of the time, and all of the people some of the time, but you can not fool all of the people all of the time.

You can fool some people some times but you cant fool all the people all the time

It is as easy unwittingly to deceive oneself as to deceive others.

Even truth can be deceptive, whatever its appearance.

On peut tromper une partie du peuple tout le temps et tout le peuple une partie du temps, mais on ne peut pas tromper tout le peuple tout le temps.

…he who seeks to deceive will always find someone who will allow himself to be deceived.

It could happen. People could be fooled. Memory is short.

So long as the deceit ran along quiet and monotonous, all of us let ourselves be deceived, abetting it unawares or maybe through cowardice...

Everything that deceives may be said to enchant.

It is not difficult to deceive the first time, for the deceived possesses no antibodies; unvaccinated by suspicion, she overlooks lateness, accepts absurd excuses, permits the flimsiest patching to repair great rents in the quotidian.

O, the tangled web we weave,
When first we practice to deceive.

It is as easy to deceive ourselves without noticing it as it is hard to deceive others without their noticing

One who deceives will always find those who allow themselves to be deceived.
