C.g. Jung said this quote

Mistakes are, after all, the foundations of truth, and if a man does not know what a thing is, it is at least an increase in knowledge if he knows what it is not.

~ C.g. Jung

Even a happy life cannot be without a measure of darkness, and the word happy would lose its meaning if it were not balanced by sadness.

~ C.g. Jung

I have frequently seen people become neurotic when they content themselves with inadequate or wrong answers to the questions of life. They seek position, marriage, reputation, outward success of money, and remain unhappy and neurotic even when they have attained what they were seeking. Such people are usually confined within too narrow a spiritual horizon. Their life has not sufficient content, sufficient meaning. If they are enabled to develop into more spacious personalities, the neurosis generally disappears.

~ C.g. Jung

The gods have become our diseases.
