The truest way to be deceived is to think oneself more knowing than others.

87.—Men would not live long in society were they not the dupes of each other. [A maxim, adds Aimé Martin, "Which may enter into the code of a vulgar rogue, but one is astonished to find it in a moral treatise." Yet we have scriptural authority for it: "Deceiving and being deceived."—2 TIM. iii. 13.]

It is as easy to unknowingly deceive yourself as it is to deceive others.

You are never so easily fooled as when trying to fool someone else.

The most ingenious men continually pretend to condemn tricking--but this is often done that they may use it more conveniently themselves, when some great occasion or interest offers itself to them.

In love deceit almost always outstrips distrust.

The intention of never deceiving often exposes us to deception.
