It would be through individual effort, inspired perhaps by reading Nietzsche's books, that the Overman might emerge, not through social or educational engineering.

Nietzsche's 'perspectivalism' was expressly directed against the 'laughable juxtaposition of "man and world"'. But 'absolutist' accounts, too, typically try to demonstrate that human beings are integral components of the world these accounts articulate - that, for example, we are simply material bodies subject to the same natural processes as everything else.

While I am happy to make the occasional foray into educational philosophy - writing, for example, of the difficulty in the contemporary context for a teacher to be 'truthful' - it is more the personal conduct of a life than social institutions that I am concerned to examine.

The main objection to the 'scientistic' claim that physics describes the world as it is in itself is that you 'can't weed out' the human contribution. That is, the scientific image of the world, like any other, is indelibly shaped by our interests, practices and prejudices.

It's one thing to assent to propositions like 'The way of things is ineffable', and quite another to internalise what it is being gestured at by such propositions, to get a sense or feel for mystery. For me, at least, it is in and through ways of engaging with nature that this sense is intimated. These ways include being in the garden.

I started my professional life as a philosopher of language and for several years took the orthodox line that meaning is an essentially linguistic phenomenon. Whether as a result of simply listening to everyday talk about meaning, or reading books of anthropology, sociology and art history, it dawned on me that there is nothing at all privileged or central about linguistic meaning.

It is hubris, claim the critics of 'absolutism', to suppose that we could ever even approximate to a true description of how the world anyway is. It is bad faith or 'bullshit', respond 'absolutists', to suppose - as the rhetoric of postmodernism implies - that we could seriously live and act with the thought that truth and value are simply our own projections. An attractive feature of 'ineffabilism', as I see it, is that it evades these accusations.
