This paper will discuss some new implications of Whitehead’s philosophy for environmental thought.[i] They fall under three headings: 1. The interrelations between three ways of thinking about the environment: bioregionalism, land ethics, and the philosophy of organism. 2. The implications of Whitehead’s philosophy of organism for environmental aesthetics. 3. The implications of Whitehead’s philosophy of organism for human communities (sustainable communities) viewed as interfused with living nature.
