J. S. Mill’s Methods IV

Nobody asked but …

There’s a lot of fur on this bear.

From Dictionary of Philosophy
Mill’s methods: Inductive methods formulated by John Stuart Mill for the discovery of causal relations between phenomena.

Method of Concomitant Variations: Whatever phenomenon varies in any manner whenever another phenomenon varies in some particular manner, is either a cause or an effect of that phenomenon, or is connected with it through some fact of causation.
