"convivial" as a technical term to designate a modern society of responsibly limited tools. // Present institutional purposes, which hallow industrial productivity at the expense of convivial effectiveness, are a major factor in the amorphousness and meaninglessness that plague contemporary society. The increasing demand for products has come to define society's process. I will suggest how this present trend can be reversed and how modern science and technology can be used to endow human activity with unprecedented effectiveness. This reversal would permit the evolution of a life style and of a political system which give priority to the protection, the maximum use, and the enjoyment of the one resource that is almost equally distributed among all people: personal energy under personal control.
