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 catalogue of forms is endless: until every shape has found its city, new cities will continue to be born. When the forms exhaust their variety and come apart, the end of cities begins.”
—Italo Calvino (1923–1985)
“If variety is capable of filling every hour of the married state with the highest joy, then might it be said that Lord and Lady Dellwyn were completely blessed, for every idea that had the power of raising pleasure in the bosom of the one, depressed that of the other with sorrow and affliction.”
—Sarah Fielding (1710–1768)
“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)
