On my second reading of this meditation on the place of mankind in Nature (Second Nature, by Michael Pollan).  Mr. Pollan is always a very good read, his thoughtful objectivity beautifully married to quiet outbursts of aesthetic passion.  This was published in 1991, some years before The Omnivore’s Dilemma, and it is obvious that he has been striving to articulate — for us, and maybe for himself — a rational understanding of man’s presence on the Earth.  Chapter 10, ‘The Idea of a Garden’, is especially lucid.
