12. Marriage of good and truth may, however, be found either in a cause
or from the cause in an effect. In a cause the marriage of good and truth
is one of will and understanding, or of love and wisdom. Such a marriage
is in all that a man wills and thinks and in all his ensuing
determinations and purposes. This marriage enters into and in fact
produces the effect. But in producing the effect, good and truth seem
distinct, for then the simultaneous turns successive. When, for example,
a man wills and thinks about food, clothing, shelter, business or
employment, or about his relationship to others, first he wills and
thinks or comes to his conclusions and intentions all at the same time;
but when these are determined to effects, truth follows on good, though
in will and thought they continue to make one. In the effects the uses
pertain to love or good, and the ways of performing the uses pertain to
understanding or truth. Anyone can confirm these general truths by
particular instances provided he perceives what is referable respectively
to good of love and to truth of wisdom, and also how differently it is
referable in cause and in effect.

13. We have said often that love constitutes man's life. This does not
mean, however, love separate from wisdom or good from truth in the cause,
for love separate or good separate is not an actuality. The love which
makes man's inmost life--the life he has from the Lord--is therefore love
and wisdom together; neither is the love which makes his life as a
recipient being separate in the cause, but only in the effect. For love
cannot be understood except from its quality, which is wisdom; and the
quality or wisdom can exist only from its own _esse,_ which is love;
thence it is that they are one; it is the same with good and truth. Since
truth is from good as wisdom is from love, it is the two taken together
that are called good or love. For love has wisdom for its form, and good
for its form truth, and form is the source, and the one source, of
