They who join to this passion as much of a desire for immortality
as our mortal nature admits, seek beauty in the perpetuity of the
procreation which renders man imperishable. They determine to
procreate and produce beauty according to nature; procreating because
their object is perpetuity; and procreating beautifully because they
possess affinity with it. In fact, perpetuity does bear affinity to
beauty; perpetual nature is beauty itself; and such also are all its
derivatives.
