My 'heroes' are those - like Chuang Tzu and Heidegger - who recognize that the world of experience is a human world, but recognize too that there is a 'way' or a 'source' to which our lives are answerable.

The demands of the economy, and more recently those of political correctness and the diktat against ever offending anyone, are not conducive to a classroom or university seminar climate in which genuinely free and critical reflection on how to live prospers.

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.

It turns out, in fact, that 'theories of meaning' are typically not about meaning in an everyday or 'folk' sense at all. They are theories designed to compute the truth or assertibility conditions of sentences from their components.

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.

One thing that attracts me in Daoism and Heidegger is a delicate combination of recognizing deep differences between human being and any other kind of being, and a desire, nevertheless, to cultivate an intimacy with animals, trees, mountains and so on.

The question of meaning goes all the way down: if human life as a whole is meaningless, so is everything that occurs or belongs within it. Since that's not a thought it is easy to live with, there is good reason to search for life's meaning.
