When I speak of a "sense-datum," I do not mean the whole of what is given in sense at one time.
Further, we know the truth 'I am acquainted with this sense-datum'.
The sense-datum with which I am acquainted in these cases is generally, if not always, complex.
And if the cat consists only of sense-data, it cannot be hungry, since no hunger but my own can be a sense-datum to me.
By a sensation I mean the fact consisting in the subject's awareness of the sense-datum.
Logically a sense-datum is an object, a particular of which the subject is aware.
In looking at a given thing and approaching it, one sense-datum will become several, and each of these will again divide.
