ed men and women frequently become interested in others than
their partners in matrimony."

Pepys, whose unconscious self-dissection admirably illustrates so
many psychological tendencies, clearly shows how--by a logic of
feeling deeper than any intellectual logic--the devotion to
monogamy subsists side by side with an irresistible passion for
sexual variety. With his constantly recurring wayward attraction
to a long series of women he retains throughout a deep and
unchanging affection for his charming young wife. In the privacy
of his _Diary_ he frequently refers to her in terms of endearment
which cannot be feigned; he enjoys her society; he is very
particular about her dress; he delights in her progress in music,
and spends much money on her training; he is absurdly jealous
when he finds her in the society of a man. His subsidiary
relationships with other women recur irresistibly, but he has no
wish either to make them very permanent or to allow them to
engross him unduly. Pepys represents a common type of civilized
"monogamist" who is perfectly sincere and extremely convinced in
his advocacy of monogamy, as he understands it, but at the same
time believes and acts on the belief that monogamy by no means
excludes the need for sexual variation. Lord Morley's statement
(_Diderot_, vol. ii, p. 20) that "man is instinctively
polygamous," can by no means be accepted, but if we interpret it
as meaning that man is an instinctively monogamous animal with a
concomitant desire for sexual variation, there is much evidence
in its favor.

Women must be as free as men to mould their own amatory life.
Many consider, however, that such freedom on the part of women
will be, and ought to be, exercised within narrower limits (see,
e.g., Bloch, _Sexual Life of Our Time_, Ch. X). In part this
limitation is considered due to the greater absorption of a woman
in the task of breeding and rearing her child, and in part to a
less range of psychic activities. A man, as G. Hirth puts it,
expressing this view of the matter (_Wege zur Liebe_, p. 342),
"has not only room in his intellectual horizon for very various
interests, but his power of erotic expansion is much greater and
more differentiated than that of women, although he may lack the
intimacy and depth of a woman's devotion."
