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:
“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)
“A poem is like a person. Though it has a family tree, it is important not because of its ancestors but because of its individuality. The poem, like any human being, is something more than its most complete analysis. Like any human being, it gives a sense of unified individuality which no summary of its qualities can reproduce; and at the same time a sense of variety which is beyond satisfactory final analysis.”
—Donald Stauffer (b. 1930)
“The measure discriminates definitely against products which make up what has been universally considered a program of safe farming. The bill upholds as ideals of American farming the men who grow cotton, corn, rice, swine, tobacco, or wheat and nothing else. These are to be given special favors at the expense of the farmer who has toiled for years to build up a constructive farming enterprise to include a variety of crops and livestock.”
—Calvin Coolidge (1872–1933)
