Variety
There are many different kinds of thought experiments. All thought experiments, however, employ a methodology that is a priori, rather than a posteriori, in that they do not proceed by observation or physical experiment.
Thought experiments have been used in a variety of fields, including philosophy, law, physics, and mathematics. In philosophy, they have been used at least since classical antiquity, some pre-dating Socrates. In law, they were well-known to Roman lawyers quoted in the Digest. In physics and other sciences, notable thought experiments date from the 19th and especially the 20th century, but examples can be found at least as early as Galileo.

Famous quotes containing the word variety:
“Please stop using the word “Negro.”... We are the only human beings in the world with fifty-seven variety of complexions who are classed together as a single racial unit. Therefore, we are really truly colored people, and that is the only name in the English language which accurately describes us.”
—Mary Church Terrell (1863–1954)
“Uses are always much broader than functions, and usually far less contentious. The word function carries overtones of purpose and propriety, of concern with why something was developed rather than with how it has actually been found useful. The function of automobiles is to transport people and objects, but they are used for a variety of other purposes—as homes, offices, bedrooms, henhouses, jetties, breakwaters, even offensive weapons.”
—Frank Smith (b. 1928)
“The best bribe which London offers to-day to the imagination, is, that, in such a vast variety of people and conditions, one can believe there is room for persons of romantic character to exist, and that the poet, the mystic, and the hero may hope to confront their counterparts.”
—Ralph Waldo Emerson (1803–1882)
