Many in the 20th century abandoned idealism. James Tartaglia now advocates for a revival of metaphysical idealism, arguing that it is misunderstood and often unfairly dismissed by the scientific establishment. By clarifying common misconceptions, Tartaglia reveals how idealism could offer significant social benefits, encouraging a more philosophical society and one focused on the primacy of experience. His new book Inner Space Philosophy: Why the Next Stage of Human Development Should Be Philosophical, Explained Radically (Suitable for Wolves) comes out on the 28th June 2024.

These days, metaphysical idealism is an immediate turn-off for most secular, scientifically minded people, who start to think of gods and spirits, maybe even Ouija boards. I think that’s a shame, because it’s a prejudice that results from some straightforward misunderstandings – misunderstandings which have greatly benefited the fortunes of idealism’s ancient metaphysical rival, materialism. To understand the potential social benefits of idealism you need to be able to take the view seriously, so let’s start by clearing away some of those misunderstandings.

Materialism is not science, it’s not even close

Firstly, idealism has no commitment to gods or spirits, only to the existential primacy of conscious experience – or, at least, that’s the kind of idealism I’m talking about, there are others. The 19^th century German philosopher Arthur Schopenhauer was no less ardent in his commitment to atheism than to idealism. I’m not denying that if you’re a believer then you’re better off with idealism than materialism – a physical God is a weird idea – but my point is simply that the two don’t necessarily need to go together. I think the idealist interpretation of reality is the best we’ve got, and I have no religious beliefs and do not believe in anything supernatural; never have, and unless something very unexpected happens, never will.
