The Heuristic Notions of Space and Time


  • James Duffy Tecnológico de Monterrey
  • Robert Henman Mount St. Vincent University
  • Terrance Quinn Middle Tennessee State University

Not only are these notions puzzling and so interesting, but they throw considerable light on the precise nature of abstraction, they provide a concrete and familiar context for the foregoing analyses of empirical science, and they form a natural bridge over which we may advance from our examination of science to an examination of common sense.
