Abstract
Professor Weiss' article assumes the point of view of the critical realist with an emphasis I would characterize as partly aesthetic and partly plain commonsense. In this article I would like to submit a pragmatic analysis of the same general concept--i.e., past, present, and future--placing more emphasis on the actual function of these concepts in cognitive inquiry and in the general activities of understanding and control in experience. Notwithstanding this difference in points of view and emphasis I do not intend to deny the general force of Professor Weiss' article. Within the framework of critical realism there can be little doubt that his arguments are on the whole valid. But I intend here to place special emphasis on certain aspects of the problems and concepts involved, and to entertain several changes of principle and terminology which to my mind will render our cognitive inquiries more intelligible.
