“A man is never more truthful than when he acknowledges himself a liar.”

“It was the last weakness he meant to indulge in; and a man never lies with more delicious languor under the influence of a passion than when he has persuaded himself that he shall subdue it to-morrow.”

“The truthful man is usually a liar.”

“Man consists in Truth. If he exposes Truth, he exposes himself. If he betrays Truth, he betrays himself.”

“A man who lies to himself is the worst liar of all.”

“There is nothing more visible than what is secret, and nothing more manifest than what is minute. Therefore the superior man is watchful over himself, when he is alone.”

“How true it is when they say there is nothing which makes a man more furious than the discovery that he has deceived himself!”

“Liars … when they speak the truth they are not believed.”

“Man is wise … when he recognises no greater enemy than himself.”

“Man is least himself when he talks in his own person. Give him a mask, and he will tell you the truth.”
