Now if someone said, “But surely something did happen when you understood the word ‘tree’, unless you were utterly absent minded when you said ‘Yes’”, I might be inclined to reflect and say to myself, “Didn't I have a sort of homely feeling || sensation when I took in the word ‘tree’?” But then, do I always have this feeling which now I referred to when I hear that word used or use it myself, do I remember having had it, do I even remember a set of, say, five sensations some one of which I had on every occasion when I could be said to have understood the word? Further, isn't that “homely feeling” I referred to an experience rather characteristic for the particular situation I'm in at present, i.e., that of philosophizing about “understanding”?
