Pessimism

mental attitude and philosophical position that dwells on the dark or gloomy side of things, the world or the universe, culminating in a sense of their vanity and nothingness that is sometimes thought to render them unworthy of existence

Pessimism is an attitude of mind and a way to look at life. Pessimists believe that generally things are bad, and the world people live in is the worst possible world.

Someone who uses the philosophy is called a pessimist, they are the opposite of an optimist.

An example of pessimism is seeing that a glass of water is "half empty", not "half full".
