2. (First objection): The manner in which the ("seminal) reasons"
of the male and female unite, in the act of generation, suffices to
account for the diversity of individuals, without implying that each
of them possesses its own ("seminal) reason." The generating principle,
the male, for example, will not propagate according to different
("seminal) reasons," since it possesses all of them, but only according
to its own, or those of its father. Since it possesses all of the
("seminal) reasons," nothing would hinder it from begetting according
to different "reasons," only, there are always some which are more
disposed to act than are others.
