A good memory is needed after one has lied.

Of all liars, the smoothest and most convincing is memory

many good liars have no imagination at all its which gives their lies such wide-eyed conviction

On average, women are better liars than men. But the best liars are men, because politicians are still predominantly men.

Robert Trivers argues, for instance, that people who can believe their own lies turn out to be the best liars of all — and an ability to deceive rivals has obvious advantages in the state of nature.

No man has a good enough memory to be a successful liar

Few of us are murderers or thieves, but we have all been liars.

Consider this a warning. Liars will lie, and continue to do so, even beyond being caught out. They will lie, and in time, such liars will convince themselves, will in all self-righteousness divest the liars of culpability.

People who write fiction, if they had not taken it up, might have become very successful liars.

I’m not a good liar, and that makes me a good liar, because liars are bad, and bad liars are good.

The ability to concoct plausible lies is a talent not to be underestimated.

If you want to become a man of letters and perhaps write some Histories one day, you must also lie and invent tales, otherwise your History would become monotonous. But you must act with restraint. The world condemns liars who do nothing but lie, even about the most trivial things, and it rewards poets, who lie only about the greatest things.

Being a practiced liar doesn't mean you have a powerful imagination. Many good liars have no imagination at all; it's that which gives their lies such wide-eyed conviction.

A liar has many points to his favour, — but he has this against him, that unless he devote more time to the management of his lies than life will generally allow, he cannot make them tally.
