sented by more than one side: it is evident, that
the impulses belonging to all these sides must
re-unite in that one figure, and become stronger
and more forcible by the union. Four sides are
supposed in the present case to have the same
figure inscribed on them, and two to have an-
other figure. The impulses of the former are,
therefore, superior to those of the latter. But
as the events are contrary, and it is impossible
both these figures can be turned up; the im-
pulses likewise become contrary, and the infe-
rior destroys the superior, as far as its strength
goes. The vivacity of the idea is always propor-
tionable to the degrees of the impulse or ten-
dency to the transition; and belief is the same
with the vivacity of the idea, according to the
precedent doctrine.
