"Nouriel Roubini has been singing the doom-and-gloom story for 10 years. Eventually something was going to be right." Personality Plus opines that pessimistic temperaments (e.g. melancholy and phlegmatic) can be useful inasmuch as pessimists' focus on the negative helps them spot problems that people with more optimistic temperaments (e.g. choleric and sanguine) miss. Other forms of pessimism Philosophical pessimism Philosophical pessimism is not a state of mind or a psychological disposition, but rather it is a worldview or philosophical position that assigns 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. Epistemological There are several theories of epistemology which could arguably be said to be pessimistic in the sense that they consider it difficult or even impossible to obtain knowledge about the world. These ideas are generally related to nihilism, philosophical skepticism and relativism. Friedrich Heinrich Jacobi (1743–1819), analyzed rationalism, and in particular Immanuel Kant's "critical" philosophy to carry out a reductio ad absurdum according to which all rationalism reduces to nihilism, and thus it should be avoided and replaced with a return to some type of faith and revelation. Richard Rorty, Michel Foucault, and Ludwig Wittgenstein questioned whether our particular concepts could relate to the world in any absolute way and whether we can justify our ways of describing the world as compared with other ways. In general, these philosophers argue that truth was not about getting it right or representing reality, but was part of subjective social relations of power, or language-games that served our purposes in a particular time. Therefore, these forms of anti-foundationalism, while not being pessimistic per se, reject any definitions that claim to have discovered absolute 'truths' or foundational facts about the world as valid. Political and cultural Philosophical pessimism stands opposed to the optimism or even utopianism of Hegelian philosophies. Emil Cioran claimed "Hegel is chiefly responsible for modern optimism. How could he have failed to see that consciousness changes only its forms and modalities, but never progresses?" Philosophical pessimism is differentiated from other political philosophies by having no ideal governmental structure or political project, rather pessimism generally tends to be an anti-systematic philosophy of individual action. This is because philosophical pessimists tend to be skeptical that any politics of social
