ABSTRACT
Natural science has its philosophical problems which can only be solved by the philosophical method of reflective analysis of the experience and critical comparison of concepts. Philosophy is distinguished from other departments of human knowledge and inquiry by the kind of questions it raises and its method of solving them, rather than by its subject-matter. Psychological introspection involves the attempt to pursue a line of cognitive activity directed by the object and grasp the meaning of each subjective act. Intuiting the passage of time, the events of past and present experience of which the subject is aware are signs of anticipated future experience, including that of its own future activity and bodily response. The total content of experience is complex, especially on the side of the object, and some features of this content tend to have a greater vividness than others, a distinction which does seem to be due to some modification on the side of the subjective act.
