A just society would be one in which liberty for one person is constrained only by the demands created by equal liberty for
another. Such a society requires as a precondition an agreement excluding tools that by their very nature prevent such liberty.
This is true for tools that are fundamentally purely social arrangements, such as the school system, as well as for tools that are
physical machines. In a convivial society compulsory and open-ended schooling would have to be excluded for the sake of
justice. Age-specific, compulsory competition on an unending ladder for lifelong privileges cannot increase equality but must

low-entropy energy. On this control of energy depends his right to give his meaning to the physical environment. His ability

society that uses large amounts of environmental energy means equal control over the transformation of that energy and not
just an equal claim to what has been done with it. 5
