TIME The two previous lectures of this course have been mainly critical.

In the present lecture I propose to enter upon a survey of the kinds of entities which are posited for knowledge in sense-awareness.

My purpose is to investigate the sorts of relations which these entities of various kinds can bear to each other.

A classification of natural entities is the beginning of natural philosophy.

To-day we commence with the consideration of Time.
In the first place there is posited for us a general fact: namely, something is going on; there is an occurrence for definition.
This general fact at once yields for our apprehension two factors, which I will name, the 'discerned' and the 'discernible.' The discerned is comprised of those elements of the general fact which are discriminated with their own individual peculiarities.
