Abstract
In advocating that we extend our experiment in political democracy in America to include economic democracy as well, the Bishops' Letter assumes the basic social nature of man. This leaves an enormous gap between the values and attitudes they recommend and the private and individualistic view of man that undergirds our traditional economic thinking. This essay attempts to bridge that gap in terms of a theory of practice, individual in emphasis, but bringing out the enabling conditions of any and all practice without which practice would not be possible. It is suggested that these presuppositions of practice function normatively in all practice, economic as well as other types, and ought to be of interest to the practice of any adequately self-interested individual. They constitute a large part of what we used to call the "public interest".
