The Overman will himself be a nihilist in the (good) sense of rejecting any metaphysical or religious grounding for truth and value, but instead of curling up in despair, or simply going along with the crowd like the 'passive' nihilist, he will recognize himself as the sole source of truths and values to live by.

In the doctrine of the world and humankind as 'will to power and nothing else', Heidegger identified not an antidote to nihilism, but the completion of it. For what can be more destructive of truth and value than the doctrine that these are simply the impositions on the world of human exercises of power?

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

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.

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.

It is indeed impossible to describe reality 'in itself', but that does not mean that our lives are answerable to nothing but our own conventions and commitments. They are answerable to a way of things that transcends the reach of our conceptual schemes.

In the final analysis, all explanations of meaning, various as they are, serve to indicate how something is 'appropriate' in and to our practices, our lives in effect.
