Abstract

I suggest that in his early, unpublished notebooks, Berkeley experimented with a radically formal conception of necessity, according to which necessity is nothing more than the inclusion of one idea within the definition of another. Berkeley's experiment was defeated by the same objective connections that rule out the existence of simple ideas. Although Berkeley was left without an understanding of the nature of necessity, he never wavered in his conviction that necessity is something objective—that ideas and the world have an inherent, inescapable structure.
