Abstract
1. Almost from the beginning of its history, it has tried to provide intelligible, systematic accounts of the world of actualities--the spatio-temporal objects which ground our daily experiences. Because of the great success of science in formulating cosmic schemes which are sustained by many widespread observations, multiple, daring predictions, and a host of desirable practical productions, many thinkers have been tempted to turn the entire task over to the sciences. Others have supposed that the philosopher has nothing more to do than to occupy himself with historical studies, logical investigations, and perhaps some asides on ethics, aesthetics, and politics.
