Optimism

Optimism is a mental attitude or world view. A common idiom used to illustrate optimism versus pessimism is a glass with water at the halfway point, where the optimist is said to see the glass as half full and the pessimist sees the glass as half empty.

The term is originally derived from the Latin optimum, meaning "best". Being optimistic, in the typical sense of the word, is defined as expecting the best possible outcome from any given situation. This is usually referred to in psychology as dispositional optimism. It thus reflects a belief that future conditions will work out for the best.

Theories of optimism include dispositional models, and models of explanatory style. Methods to measure optimism have been developed within both theoretical systems, such as various forms of the Life Orientation Test, for the original definition of optimism, or the Attributional Style Questionnaire designed to test optimism in terms of explanatory style.

Variation in optimism and pessimism is somewhat heritable and reflects biological trait systems to some degree. It is also influenced by environmental factors, including family environment, with some suggesting it can be learned. Optimism may also be linked to health.

Noam Chomsky

Avram Noam Chomsky (/ˈnoʊm ˈtʃɒmski/; born December 7, 1928) is an American linguist, philosopher, cognitive scientist, historian, logician, social critic, and political activist. Sometimes described as "the father of modern linguistics," Chomsky is also a major figure in analytic philosophy, and one of the founders of the field of cognitive science. He has spent most of his career at the Massachusetts Institute of Technology (MIT), where he is Institute Professor Emeritus, and is the author of over 100 books, primarily on politics and linguistics. Ideologically, he aligns with anarcho-syndicalism and libertarian socialism.

Born to a middle-class Ashkenazi Jewish family in Philadelphia, Chomsky developed an early interest in anarchism from alternative bookstores in New York City. At the age of sixteen he began studies at the University of Pennsylvania, taking courses in linguistics, mathematics, and philosophy. He married fellow linguist Carol Schatz in 1949. From 1951 to 1955 he was appointed to Harvard University's Society of Fellows, where he developed the theory of transformational grammar for which he was awarded his doctorate in 1955. That year he began teaching at MIT, in 1957 emerging as a significant figure in the field of linguistics for his landmark work Syntactic Structures, which laid the basis for the scientific study of language, while from 1958 to 1959 he was a National Science Foundation fellow at the Institute for Advanced Study. He is credited as the creator or co-creator of the universal grammar theory, the generative grammar theory, the Chomsky hierarchy, and the minimalist program. Chomsky also played a pivotal role in the decline of behaviorism, being particularly critical of the work of B. F. Skinner.
