When I was 16 I started keeping a diary in which I recorded my disagreements with the famous philosophers. I didn't insist that they were wrong, that I was right and I had to prevail. I just agreed and disagreed with them. I thought there was a high degree of probability that I was right and some other thinkers were wrong. But I wasn't positive about it.

I teach people to be flexible, scientific and logical in their thinking and therefore to be less prone to brainwashing by the therapist.

Convince yourself that worrying about many situations will make them worse rather than improve them.

There's no evidence whatsoever that men are more rational than women. Both sexes seem to be equally irrational.

Many psychoanalysts refused to let me speak at their meetings. They were exceptionally vigorous because I had previously been an analyst and they were very angry at my flying the coop.

Lack of forgiveness of others breeds lack of self-forgiveness.

People could rationally decide that prolonged relationships take up too much time and effort and that they'd much rather do other kinds of things. But most people are afraid of rejection.
