Being a blockhead is sometimes the best security against being cheated by a man of wit.

Treachery is more often the effect of weakness than of a formed design.

The cunningest dissimulation is when a man pretends to be caught in the traps others set for him; and a man is never so easily over-reached as when he is contriving to over-reach others.

The intention of cheating no one lays us open to being cheated ourselves.
