`Tis not contrary to reason to prefer the destruction of the whole world to the scratching of my finger' -- David Hume -- Treatise on Human Nature (ed. Selby-Bigge, p. 416). --- This strikes me as anti-Heideggerian. Heidegger, it is well known, thought that most western metaphysics was misguided. It lacked 'the concept of the 'sein-in-der-welt' (to be in the world). Mutatis mutandis: 'Tis not contrary to reason to prefer the destruction of the whole world to the scracthing of my (i.e. Hume's) finger --- BUT: the finger is part of the world. --- Therefore: it IS contrary to reason. Speranza -- Bordighera
