good and truth, and from this marriage is the church; and as the church
is various and different in the several parts of the world, therefore
also the souls of all men are various and different; wherefore internal
similitudes and dissimilitudes are from this source, and according to
them the conjugial conjunctions of which we have been treating; but
external similitudes and dissimilitudes are not of the souls but of
minds; by minds (_animos_) we mean the affections and thence the
external inclinations, which are principally insinuated after birth by
education, social intercourse, and consequent habits of life; for it is
usual to say, I have a mind to do this or that; which indicates an
affection and inclination to it. Persuasions conceived respecting this
or that kind of life also form those minds; hence come inclinations to
enter into marriage even with such as are unsuitable, and likewise to
refuse consent to marriage with such as are suitable; but still these
marriages, after a certain time of living together, vary according to
the similitudes and dissimilitudes contracted hereditarily and also by
education; and dissimilitudes induce cold. So likewise dissimilitudes of
manners; as for example, an ill-mannered man or woman, joined with a
well-bred one; a neat man or woman, joined with a slovenly one; a
litigious man or woman, joined with one that is peaceably disposed; in a
word, an immoral man or woman, joined with a moral one. Marriages of
such dissimilitudes are not unlike the conjunctions of different species
of animals with each other, as of sheep and goats, of stags and mules,
of turkeys and geese, of sparrows and the nobler kind of birds, yea, as
of dogs and cats, which from their dissimilitudes do not consociate with
each other, but in the human kind these dissimilitudes are indicated not
by faces, but by habits of life; wherefore external colds are from this
source.
