There are men (and I think Priestley was one of them) to whom the
satisfaction of throwing down a triumphant fallacy is as great as that
which attends the discovery of a new truth; who feel better satisfied
with the government of the world, when they have been helping Providence
by knocking an imposture on the head; and who care even more for freedom
of thought than for mere advance of knowledge. These men are the Carnots
who organise victory for truth, and they are, at least, as important as
the generals who visibly fight her battles in the field.
