The essays in this volume, first published in 1986, examine the
philosophical foundations of social choice theory. This field, a modern
and sophisticated outgrowth of welfare economics, is best known for a
series of impossibility theorems, of which the first and most crucial
was proved by Kenneth Arrow in 1950. That has often been taken to show
the impossibility of democracy as a procedure for making collective
decisions. However, this interpretation is challenged by several of the
contributors here. Other central issues discussed in the volume include
the possibility of making interpersonal comparisons of utility, the
question of whether all preferences are equally to be valued, and the
normative individualism underlying the theoretical tradition. Criticisms
of social choice theory are advanced and suggestions for alternative
approaches are developed.
