OPTIMISM

Optimism is "an inclination to put the most favorable construction upon actions and events or to anticipate the best possible outcome". It is the philosophical opposite of pessimism. Optimists generally believe that people and events are inherently good, so that most situations work out in the end for the best.

Alternatively, some optimists believe that regardless of the external world or situation, one should choose to feel good about it and make the most of it. This kind of optimism doesn't say anything about the quality of the external world; it's an internal optimism about one's own feelings.

A common conundrum illustrates optimism-versus-pessimism with the question, does one regard a given glass of water, filled to half its capacity, as half full or as half empty? Conventional wisdom expects optimists to reply, "Half full," and pessimists to respond, "Half empty" (assuming that "full" is considered good, and "empty", bad).

Another paradox sometimes associated with optimism is that the only thing an optimist cannot view as positive is a pessimist. Pessimism, however, as it acts as a check to recklessness, may even then be viewed in a positive light.

Philosophy : - Philosophers often link the concept of optimism with the name of Gottfried Wilhelm Leibniz, who held that we live in the best of all possible worlds, or that God created a physical universe that applies the laws of physics, which Voltaire famously mocked in his satirical novel Candide. The philosophical pessimism of William Godwin demonstrated perhaps even more optimism than Leibniz. He hoped that society would eventually reach the state where calm reason would replace all violence and force, that mind could eventually make matter subservient to it, and that intelligence could discover the secret of immortality. Much of this philosophy is exemplified in the Houyhnhnms of Jonathan Swift's Gulliver's Travels.

Panglossianism : - The term "panglossianism" describes baseless optimism of the sort exemplified by the beliefs of Pangloss from Voltaire's Candide, which are the opposite of his fellow traveller Martin's pessimism and emphasis on free will. The phrase "panglossian pessimism" has been used to describe the pessimistic position that, since this is the best of all possible worlds, it is impossible for anything to get any better.

The panglossian paradigm is a term coined by Stephen Jay Gould and Richard Lewontin to refer to the notion that everything has specifically adapted to suit specific purposes. Instead, they argue, accidents and exaptation (the use of old features for new purposes) play an important role in the process of evolution. Some other scientists however argue that the implication that many (or most) adaptionists are panglossians is a straw man.
