A thought experiment or Gedankenexperiment (from German) considers some hypothesis, theory, or principle for the purpose of thinking through its consequences. Given the structure of the experiment, it may or may not be possible to actually perform it, and, in the case that it is possible for it to be performed, there need be no intention of any kind to actually perform the experiment in question. The common goal of a thought experiment is to explore the potential consequences of the principle in question.
Famous examples of thought experiments include Schrödinger's cat, illustrating quantum indeterminacy through the manipulation of a perfectly sealed environment and a tiny bit of radioactive substance, and Maxwell's demon, which attempts to demonstrate the ability of a hypothetical finite being to violate the second law of thermodynamics.

Famous quotes containing the words thought and/or experiment:
“It has come to be practically a sort of rule in literature, that a man, having once shown himself capable of original writing, is entitled thenceforth to steal from the writings of others at discretion. Thought is the property of him who can entertain it; and of him who can adequately place it. A certain awkwardness marks the use of borrowed thoughts; but, as soon as we have learned what to do with them, they become our own.”
—Ralph Waldo Emerson (1803–1882)
“What constitutes a real, live human being is more of a mystery than ever these days, and men—each one of whom is a valuable, unique experiment on the part of nature—are shot down wholesale.”
—Hermann Hesse (1877–1962)
