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.

It's as if, for Schopenhauer and perhaps Kant, the mind is there up and running, equipped with its categories and concepts that it then projects or smears, as it were, over what impinges upon it from the outside. This is not the image you find in, for example, Chuang Tzu: minds and nature are inseparably fused in an ever-changing whole of experience that, so to speak, constantly wells up from an indescribable source in a process that Daoists call 'the way' or 'the course'.

The garden is as good a symbol as you can find of a dialectic between spheres of experience - of culture and nature - that presuppose one another.

For me, the existentialists are important critics of 'absolutist' claims, and Heidegger and Merleau-Ponty are, at least in their later writings, also exponents of a doctrine of mystery: Being or the 'well-spring' of everything is, for Heidegger, ineffable, just as what Merleau-Ponty called 'Flesh' is for him.

How people make gardens is bound to reflect a way of experiencing the natural world, while at the same time this experience of nature is bound to reflect a culture - ways of painting nature, for example, or representing nature in literature, or of course making gardens.

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.

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.
