Pessimism, Philosophical opinion or doctrine that evil predominates over good; the opposite of optimism
Systematic forms of pessimism may be found in philosophy and religion. In religion Buddhism and Hinduism pessimistically appraise the world, while Christianity's pessimism is more restricted. Numerous philosophers have been pessimistic, notably Arthur Schopenhauer in the 19th cent. and Martin Heidegger in the 20th cent.
Sigmund Freud could also be described as a pessimist and he shared many of Schopenhauer's ideas. He saw human existence as being under constant attack from both within the self, from the forces of nature and from relations with others.
