Portrait of John Stuart Mill John Stuart Mill A System of Logic, Ratiocinative and Inductive (1843)

And if we carry our observation outward, we also find that light and darkness, sound and silence, motion and quiescence, equality and inequality, preceding and following, succession and simultaneousness, any positive phenomenon whatever and its negative, are distinct phenomena, pointedly contrasted, and the one always absent where the other is present. I consider the maxim in question to be a generalization from all these facts.

A phenomenon and an intrinsic form signify, at the moment of perception, the thing, the object which the conditions of our senses enable us to perceive, and the intrinsic power of this phenomenon implies a cause. Natural phenomena and beings are thus reciprocally linked together as causes and effects, an effect becoming in its turn the cause of a subsequent fact; that is, when we consider things in themselves, and not relatively to the animal or man who apprehends them.
