A high degree of intellect tends to make a man unsocial. - Arthur Schopenhauer

Thus also every keen pleasure is an error and an illusion, for no attained wish can give lasting satisfaction.

The two enemies of human happiness are pain and boredom.

A constant flow of thoughts expressed by other people can stop and deaden your own thought and your own initiative…. That is why constant learning softens your brain…. Stopping the creation of your own thoughts to give room for the thoughts from other books reminds me of Shakespeare’s remark about his contemporaries who sold their land in order to see other countries.
