Note 139 — CANTO THE SECOND
Reading edition
[Mr. Tozer (Childe Harold, p. 236) takes this line to mean "whom the young love to talk of, and the wise to follow as an example," and points to Alexander's foresight as a conqueror, and the "extension of commerce and civilization" which followed his victories. But, surely, the antithesis lies between Alexander the ideal of the young, and Alexander the deterrent example of the old. The phrase, "beacon of the wise," if Hector in Troilus and Cressida (act ii. sc. 2, line 16) is an authority, is proverbial.
" ... The wound of peace is surety, Surety secure; but modest doubt is call'd The beacon of the wise, the tent that searches To the bottom of the worst."
The beauty, the brilliance, the glory of Alexander kindle the enthusiasm of the young; but the murder of Clytus and the early death which he brought upon himself are held up by the wise as beacon-lights to save others from shipwreck.]
