Our memory of exact word sequences usually fades more quickly than our memory of (contextually interpreted) meanings.
More broadly, the exact auditory sensations normally fade very quickly; the corresponding word sequences fade a bit more slowly; and the interpreted meanings last longest.
These generalizations can be overcome to some extent if the sound or the text has especially memorable characteristics. (And the question of what "memorable" means in this context is interesting.)
Most likely to succeed in defining Japanese aesthetics is a net of associations composed of listings or jottings, connected intuitively, that fills in a background and renders the subject visible.
We have been given a standard to use. It is there, handy daily: things as they are, or Nature itself. This makes good sense, the only sense really—Nature should be our model.
