A Journey of No Return, Not a Circular Economy

By Herman Daly

The economic process is not a mechanical analog that can be run forward and backward, nor a circular process that can return to any previous state. Rather it is an irreversible and irrevocable process moving in the direction of time’s arrow of increasing entropy [1]. Finitude and entropy guarantee that the economic life of our species will be a journey of no return. Therefore even a stationary economy, in the classical sense of constant population and constant capital stock, is ultimately a journey of no return, because the metabolic throughput of matter and energy required to maintain constant stocks of people and physical capital, in the face of depreciation and death, is an entropic flow from ever less concentrated sources to ever filling sinks – and both sources and sinks are finite.


Neocornucopianism and the Steady State: Part I

By Josh Farley

Perhaps the main reason people reject the need for a steady state economy is some form of cornucopianism, the belief that technological progress will overcome all ecological and physical limits, allowing endless economic growth into the indefinite future. Cornucopianism has several flavors, and I will describe three: mainstream economics, eco-modernism, and singularity theory.
