Abstract
This paper deals with the relationships between ethics and the environment in Rousseau’s thought. The concept of environment is understood in its various dimensions. What is at stake is the natural, as well as the social and political, environment of human beings. The notion of ethics is also understood in a broad sense. We do not set ethics, understood as the search for happiness (or for the good life) against morality, understood as the fulfillment of duty. However, we take up two main questions. The first question concerns the influence of the environment, both natural and social, upon the ethical development of human beings. The second question concerns the responsibility of human beings towards nature. We examine what Rousseau teaches us regarding these two questions. Finally, we envisage liberty from the point of view of the relationships between nature and the political order. Human liberty is a matter of rights. It depends upon the republican nature of the state. However, liberty is also a sentiment that is intimately related to the living experience of nature. In order to understand what Rousseau means by liberty, we must grasp this intimate relationship between nature and politics.
