Sincerity makes an untruth seem like a truth, while insincerity makes a truth seem like an untruth.
Marriage always demands the greatest understanding of the art of insincerity possible between two human beings.
The great enemy of clear language is insincerity. When there is a gap between one's real and one's declared aims, one turns as it were instinctively to long words and exhausted idioms, like cuttlefish squirting out ink.
There is no wickedness so desperate or deceptive - we can never foresee its consequences. Of all the evil spirits abroad in the world, insincerity is the most dangerous.

My daughter’s direct, spontaneous, and affectionate nature released me from many of the protective mechanisms I had developed, above all the fear that my love might be exploited. With her I had no need to protect myself. At last I could love, trust, and be tender without any apprehensions about my openness being misused for corrective educational purposes – as was the case with my mother – or my feelings being hurt. As I did not have the good fortune of enjoying an open and warmhearted relationship with my mother, this new opportunity for communication – for all its tragic aspects and the restrictions it brought with it – was more of a blessing than anything else… The spontaneity with which my daughter expressed her childlike, innocent, affectionate nature at whatever age she happened to be, and her sensitivity to insincerity and disingenuousness in whatever form, gave my life new dimensions and new objectives.
