I can only note that the past is beautiful because one never realises an emotion at the time. It expands later, and thus we don't have complete emotions about the present, only about the past.
Personal beauty is then first charming and itself, when it dissatisfies us with any end; when it becomes a story without an end; when it suggests gleams and visions, and not earthly satisfactions; when it makes the beholder feel his unworthiness; when he cannot feel his right to it, though he were Caesar; he cannot feel more right to it than to the firmament and the splendors of a sunset.
Beauty depends on size as well as symmetry. No very small animal can be beautiful, for looking at it takes so small a portion of time that the impression of it will be confused. Nor can any very large one, for a whole view of it cannot be had at once, and so there will be no unity and completeness.
Never lose an opportunity to see anything that is beautiful. It is God's handwriting a wayside sacrament. Welcome it in every fair face, every fair sky, every fair flower.
Beauty is an experience, nothing else. It is not a fixed pattern or an arrangement of features. It is something felt, a glow or a communicated sense of fineness.
When people see some things as beautiful, other things become ugly. When people see some things as good, other things become bad. Being and non-being create each other. Difficult and easy support each other. Long and short define each other. High and low depend on each other. Before and after follow each other. Therefore the Master acts without doing anything and teaches without saying anything. Things arise and she lets them come; things disappear and she lets them go. She has but doesn't possess, acts but doesn't expect. When her work is done, she forgets it. That is why it lasts forever.
