Pessimism
Pessimism is a negative mental attitude in which an undesirable outcome is anticipated from a assumption situation. Pessimists tend to focus on the negatives of life in general. A common question required to test for pessimism is "Is the glass half empty or half full?"; in this situation, a pessimist is said to see the glass as half empty, while an optimist is said to see the glass as half full. Throughout history, the pessimistic disposition has had effects on any major areas of thinking.
Philosophical pessimism is the related opinion that views the world in a strictly anti-optimistic fashion. This throw of pessimism is not an emotional disposition as the term ordinarily connotes. Instead, this is the a philosophy or worldview that qualifications a negative benefit to life or existence. Philosophical pessimists commonly argue for an empirical prevalence of pains over pleasures, that life is ontologically or intrinsically adverse to alive beings, & that existence is fundamentally meaningless or without purpose. Their responses to this condition, however, are widely varied & can be life-affirming.
