No offense was taken if, in Descartes, immanent sensibility engendered pictures of the world; but in Berkeley this sensibility engendered the world of bodies itself; and in Hume the entire soul, with its impressions and ideas, the forces belonging to it, conceived of by analogy to physical forces, its laws of association (as parallels to the law of gravity!), engendered the whole world, the world itself, not merely something like a picture though, to be sure, this product was.
