The traditional positivist model is an inadequate foundation for socio
logy as a science. The phenomena of society differ from the phenomena
assumed by positivism and existing in the world of nature in ways that
prevent the successful use of that traditional approach. Agency, the
ability to choose among alternatives where the choice makes an importa
nt difference, exists in social phenomena but has no counterpart in na
ture and cannot be dealt with adequately by positivism. A technologica
l science perspective is suggested as an alternative for a science of
sociology that can deal with the reality and importance of agency. Eig
ht differences between the traditional perspective and the alternative
are sketched. The alternative requires changes in the kind of general
ized knowledge produced and the way it is produced, accumulated, and r
efined. The changes, though seemingly small, would produce a major rec
onstruction of much of sociology; such changes could result in importa
nt progress by the field of sociology.
