Abstract
Specifically, the aim of a philosophical investigation of science which is cosmological in orientation would be formulated differently in the light of different views of the status of scientific theories. The realist, who treats theory as a literal description of the world, will, predictably, set his sights on, say, finding from theory the nature of time itself. The time of everyday experience is then explained as a by-product of interaction with the world. The positivist, who does not treat theory as a literal description of the world, will instead set his sights on describing the concept of time in a certain theory or, if he shares the present historical mood, on describing the development of that concept through successive theories. His particular epistemological bias does not bar the way to an investigation of the time of everyday experience which would proceed independently of science.
