This is mainly in response to
@Banno and
@Jamals posts, but it may be relevant to others involved in the discussion on the thread too. I had a slower read of the essay by Iris Murdoch' 's 'A House of Theory'. In her examination of the idea of the elimination of metaphysics, she is pointing to specific problems raised by metaphysicians who came up with 'dogmatic metaphysical arguments'. She points to the way in which both Kant and Hume, as well as Hegel, were important in the development of empiricism. The essential point is that she is arguing for is the importance of 'philosophical method' as opposed to mere beliefs. She states,
'Hume, whose "elimination" followed the simple lines of atomic empiricism, regarded all beliefs equally irrational...Kant more systematically attempted to show why our knowledge was limited to certain kinds of object, and, in doing so pictured the mind as solely concerned with the objects of empirical observation and science
However, she does acknowledge the addition Kant had 'of belief in Reason, with the tentative belief in God'. I actually think that this aspect is glossed over by Murdoch, because belief in God is such a major concept metaphysically
However, the main point which Murdoch is making is making is the emphasis on empiricism. She states that, 'Modern British philosophy is Humian and Kantian in inspiration. It follows Hume and Kant in regarding sense experience as the only basis for knowledge, and it follows Kant in attempting more specifically to show that concepts not so based are "empty".
I am adding this to the discussion to give a clearer picture of her underlying outlook, and she also speaks of 'the error by which former philosophers imagined themselves to be making quasi-factual discoveries when really they were preaching'. Her overall argument is that there needs to be a rational, empirically basis for philosophy and that this is 'A House of Theory'.
Murdoch wrote this essay in 1958, so the issue of the 'elimination of metaphysics' is different because scientific knowledge has come a long way. However, it is worth being aware of her historical argument but it may have different implications in the context of twentieth first century thinking.
