1991 0-7734-9767-6 Keeling leads us to a view that our conventional idea of time is mistaken and that the true nature of what we misperceive as temporality is to be found in the nature of change. The work which was the last philosophical enterprise of his career constitutes only part of a more complete work which he had in mind. Keeling reviews our common views of time and finds that though in our everyday lives they are satisfactory enough, none of them are satisfactory as philosophical criteria. Keeling describes a world where the present, as the domain of change, is the only reality and the only place where action can occur. The successive renewal of presentness is the ultimate significance of what we believe in as time.
