B. G. Jefferis and J. L. Nichols, Searchlights on Health — Jealousy--Its Cause and Cure (1919)
“ NOBLEST JEALOUSY.—The noblest jealousy, if the term noble is appropriate, is a sort of ambition or pride of the loving person who feels it is an insult that another one should assume it as possible to supplant his love, or it is the highest degree of devotion which sees a declaration of its object in the foreign invasion, as it were, of his own altar. Jealousy is always a sign that a little more wisdom might adorn the individual without harm. ”
