Notes:
[1] Horace, Epist: II., 1, 180.
[2] Let me remark that people in the highest positions in life, with all their brilliance, pomp, display, magnificence and general show, may well say:—Our happiness lies entirely outside us; for it exists only in the heads of others.
[3] Scire tuum nihil est nisi te scire hoc sciat alter, (Persins i, 27)—knowledge is no use unless others know that you have it.
