sensual attraction, illusion, fancy, deception, hate,
satiety, enthusiasm, reasoning calculation, etc., are
contained in the _mixtum compositum_ which the enamoured
persons call love."

This list, moreover, does not accurately name a single one of
the essential ingredients of true love, dwelling only on associated
phenomena, whereas Shakspere's lines call attention to three states of
mind which form part of the quintessence of romantic love--gallant
"service," "adoration," and "purity"--while "patience and impatience"
may perhaps be accepted as an equivalent of what I call the mixed
moods of hope and despair.

HERBERT SPENCER'S ANALYSIS

Nevertheless the first thinker who treated love as a compound feeling
and consciously attempted a philosophical analysis of it was Herbert
Spencer. In 1855 he published his _Principles of Psychology_, and in
1870 appeared a greatly enlarged edition, paragraph 215 of which
contains the following exposition of his views:

"The passion which unites the sexes is habitually
spoken of as though it were a simple feeling; whereas
it is the most compound, and therefore the most
powerful, of all the feelings. Added to the purely
physical elements of it are first to be noticed those
highly complex impressions produced by personal beauty;

affection--a sentiment which, as it exists between
those of the same sex, must be regarded as an
independent sentiment, but one which is here greatly
exalted. Then there is the sentiment of admiration,
respect, or reverence--in itself one of considerable
power, and which in this relation becomes in a high
degree active. There comes next the feeling called love
of approbation. To be preferred above all the world,
and that by one admired beyond all others, is to have
the love of approbation gratified in a degree passing
every previous experience: especially as there is added
that indirect gratification of it which results from
the preference being witnessed by unconcerned persons.
Further, the allied emotion of self-esteem comes into
play. To have succeeded in gaining such attachment
