PHIL 3140 Environmental Ethics

About the Course

Two main approaches govern environmental philosophy. Many philosophers see environmental ethics as a kind of problem to apply traditional ethical theories. Traditionally, ethics concerns our obligations to other persons and these philosophers contend that we ought to protect the environment because we owe it to other people. These philosophers still exhibit plenty of disagreement, no less than philosophers on any other ethical controversy. For example, some philosophers argue that our obligation to others concerning the environment should aim to produce the greatest good for the greatest number. This view reflects the conservation policy of the first chief of US Forest service, Gifford Pinchot, who sought a more equitable use of natural resources. Alternately, some philosophers have argued that it is wrong to allow people to experience some level of pollution, even if it maximizes utility. Such claims are made against the background of the ethics of Immanuel Kant or a theory of justice like that of John Rawls. Still other philosophers argue that environmental ethics can be understood in terms of human virtues and vices. For example, some argue that excessive consumption not only fails to maximize utility but is a vice akin to gluttony. On the other hand they might argue that taking care of the environment might be understood as the virtue of stewardship.
