SUPERVENIENCE, WEAK: Where A and B are things, facts, events, or properties, B weakly supervenes on A if and only if nothing will vary in its B-features without also correspondingly varying in its A-features, or alternatively: no two things will share all their A-features in common unless they also will share all their B features in common, or again alternatively: any two things that are identical with respect to all their A-features will also be identical with respect to all their B-features.


The principal difference between weak and strong supervenience is that weak supervenience preserves the co-variation element of strong supervenience, without either the upwards necessitation element in particular, or necessitation more generally.

The Fate of Analysis (2021)

Robert Hanna’s twelfth book, The Fate of Analysis, is a comprehensive revisionist study of Analytic philosophy from the early 1880s to the present, with special attention paid to Wittgenstein’s work and the parallels and overlaps between the Analytic and Phenomenological traditions.

By means of a synoptic overview of European and Anglo-American philosophy since the 1880s—including accessible, clear, and critical descriptions of the works and influence of, among others, Gottlob Frege, G.E. Moore, Bertrand Russell, Alexius Meinong, Franz Brentano, Edmund Husserl, The Vienna Circle, W.V.O. Quine, Saul Kripke, Wilfrid Sellars, John McDowell, and Robert Brandom, and, particularly, Ludwig Wittgenstein—The Fate of Analysis critically examines and evaluates modern philosophy over the last 140 years.

In addition to its critical analyses of the Analytic tradition and of professional academic philosophy more generally, The Fate of Analysis also presents a thought-provoking, forward-looking, and positive picture of the philosophy of the future from a radical Kantian point of view.
