Philosophical pessimism is a family of philosophical views that assign a negative value to life or existence. Philosophical pessimists commonly argue that the world contains an empirical prevalence of pains over pleasures, that existence is ontologically or metaphysically adverse to living beings, and that life is fundamentally meaningless or without purpose. Philosophical pessimism is not a single coherent movement, but rather a loosely associated group of thinkers with similar ideas and a resemblance to each other.[1]: 7 Their responses to the condition of life are widely varied. Philosophical pessimists usually do not advocate for suicide as a solution to the human predicament; though many favour the adoption of antinatalism, that is, non-procreation.
