Due to the unreliable performance of my internet connection (dial-up!), I am forced to start with a summary, which can be fleshed out with subsequent posts.
My philosophical view is informed chiefly by David Hume, Nietzsche, Bertrand Russell, and the Logical Positivists (LP’s). There is a direct connection – a line of thinking – running straight through all these thinkers, and it is that line of reasoning that I basically accept. Moreover, there is a set of premises, derived from and/or informing this line of thinking that I also accept.
The result is that I am a materialist, conceived of in a minimal sense (weak materialism, basically); an atheist (also weak); that I possess nothing that can rightly be called an epistemic or ontological view (although I could perhaps be persuaded otherwise); and that I view philosophy not as a path to knowledge, but as a study of language.
Hume established that epistemology and ontology belongs to metaphysics; that causation is not phenomenal or logical, but is psychological; that essentialism applied to human nature is nonsensical; and that induction is not, strictly speaking, logic at all. He also made philosophy safe for atheism and for the primacy of sensory experience. He defeated Descartes, in other words, in a decisive and fecund way.
Nietzsche accepts all this. He assumes Hume. Unlike Hume, Nietzsche makes no argument against God and provides only sporadic salvos against metaphysics in general. Nietzsche seizes upon the idea that knowledge is a psychological phenomenon and not an epistemic one, even that it is a psychological necessity – but only that. Hume dissolved the need for epistemology, and Nietzsche possesses none. Nietzsche’s focus was different – he saw metaphysics as a purely social phenomenon. He understood that Plato was held hostage by language, by words – that language (and not knowledge) was the very subject matter of philosophy.
Hume lived, philosophically, in a godless universe, and Nietzsche explored the ramifications of such a universe. He virtually abandoned deductive logic, and relied on induction only as a way of compiling evidence, and not to prove anything. In Nietzsche, we have a shift to truth as a function of language, of psychology alone. While Hume told us that we are truly alone, Nietzsche turns Descartes’ subjectivity on its head – God id not deceiving us – we are deceiving ourselves, and necessarily so.
Russell, despite a lack of affinity to Nietzsche, studied language. He realized that logic was mathematics (through Frege) and so was a closed system, not connected to empirical world. In doing so, he rescued deductive logic from the rationalists – the very people that Hume and Nietzsche so despised. Specifically in his study of language, he sought to show that logic cannot be directed at knowledge – that logic shows us only what we are saying – that it does not allow us to say that we know anything in an epistemic or phenomenal sense. In doing so, he set the stage for the LP’s – and like Hume and Nietzsche, tried to keep philosophy within the realm of that which can be verified. He helped to “scientificalise†philosophy. Along with the LP’s, he sought to show the relationship between logic, language and the phenomenal world.
This led to an agreement between the LP’s and Nietzsche – that morality is a human convention, with a meaning that is assigned by humans – and only that. Every rationalist, or metaphysical morality can now be seen as a pure invention. This changes the way all philosophy is now viewed – it has almost meant the demise of morality itself, within philosophy. Even a Kantian like John Rawls must noe appeal to social scientists, at least.
I think I have to post this now. Too long for my pathetic connection. It’s really only a sketch.
