There is no rationality that is not first ecological

John Dryzek's concept of ecological rationality provides a framework for justifying policy decisions on ecological grounds. According to Dryzek, ecological rationality deserves precedence over the other rationalities, such as social, economic, and political, because without a stable biosphere the other realms of human endeavor cannot continue to exist. The present article aims to support and extend Dryzek's concept by asserting that other rationalities cannot have their own internal logic or achieve their own objectives if they are not also ecologically rational. Ecological rationality is a precondition if other forms of reasoning are to be considered valid. This generates new implications for Dryzek's original concept. In an era of climate change and ecological instability, this extension provides a more powerful framework for justifying public sphere and policy decision-making that prioritizes environmental principles. Contemporary examples and limitations are discussed.
