One of philosopher John Stuart Mills’ five methods of induction, intended to illustrate the concept of causation. The method of difference states: “if an instance in which the phenomenon under investigation occurs, and an instance in which it does not occur, have every circumstance in common save one, that one occurring in the former, the circumstance in which alone the two instances differ is the effect, or the cause, or an indispensable part of the cause, of the phenomenon.”
