The age of materialism
Our philosophical age is characterised by materialism, more properly called naturalistic monism (see footnote). We live in the wake of a monumental revolution, one that took place over the course of the C20th, though prepared by the Enlightenment of the C18th; during this revolution the cosmology of Christianity was overthrown as the predominant ideology of the academic class, and was replaced by naturalistic monism. The intellectual elite as a body no longer believes in the primacy of spirit; it believes that all phenomena are determined by nature, which exists independently of and not for spirit. If spirit is admitted, it is as a dependent ephiphenomenon, and not for itself. This ideology goes hand-in-hand with the epistemology of empiricism, or more specifically, positivism.
No way forward for materialism
While contemporary Western philosphy contrives to ignore it, as a system of faith it is already defunct. The great project of explaining everything and all in terms of a single principle - that of matter - has already collapsed. The dream of demonstrating the material basis of the mind, by building a machine that can act as a man, has already failed. We need to move on.
