The focus of environmental ethics should indeed be on the virtues and how these inform our relationship to natural environments.

I think it's true that for existentialist thinkers, appreciation of what we are - free, makers of meaning, 'issues' for ourselves, and so on - is at the same time a recognition of how we should try to live.

To describe this world is not to describe reality 'in itself', as it is independently of how we regard and describe it.

The writing I have in mind and sometimes indulge in myself is concerned, not with plants, mountains or birds as items of scientific description, but with experiences of nature that impinge upon our moods and emotions, enrich our imagination and reveries, and shape our sense of how we stand in relation to the environing world. In a broad sense of the term, this kind of writing is an exercise in phenomenology, an attempt to render the significance that birds, plants or whatever have for us.

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.

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 dis-incumbenced stance is the one people should cultivate, we are told, once they recognize that there is no world beyond the human world. They will, indeed must, have their beliefs and values, but they will recognize that these 'lean upon' - and are answerable to - nothing other than human commitments and purposes. The only fidelity, Rorty remarked, can be to our own conventions.
