In fact, equality, as an abstract idea, does not
have much cutting power, and the real work begins
with the specification of what is it that is to be
equalized. The central step, then, is the specification
of the space in which equality is to be sought,
and the equitable accounting rules that may be
followed in arriving at aggregative concerns as well
as distributive ones. The content of the respective
theories turns on the answers to such questions as
‘equality of what?’ and ‘equity in what form?’(On
this see [2].)
