While all deception requires secrecy, all secrecy is not meant to deceive.

Liars share with those they deceive the desire not to be deceived.

We are all, in a sense, experts on secrecy. From earliest childhood we feel its mystery and attraction. We know both the power it confers and the burden it imposes. We learn how it can delight, give breathing space and protect.

Self-deception helps us deceive,

It is double pleasure to deceive the deceiver.

All those who are not straightforward (frank and forthright) in this world are full of deception.
