revolutions, it was probable to find such despots arising out of the
middle class; and that, from the condition of reaction incidental to all
human violences, there was a clear expectability that the power of such
military monarchs should not be continued to their natural heirs.

Such a line of argument, although in no measure required for the
corroboration of facts, might have considerable power to persuade _a
priori_ the man, who had not hitherto seen reason to credit such facts
from posterior evidence. It would have rolled away a great stone, which
to such a mind might otherwise have stood as a stumbling-block on the
very threshold of truth. It would have cleared off a heavy mist, which
might prevent him from discerning the real nature of the scene in which
he stood. It would have shown him that, what others know to be fact, is,
even to him who does not know it, become antecedently probable; and that
Reason is not only no enemy to Faith, but is ready and willing to
acknowledge its alliance.

Take a second illustration, by way of preliminary. A woodman, cleaving
an oak, finds an iron ball in its centre; he sees the fact, and of
course believes; some others believing on his testimony. But a certain
village-pundit, habitually sceptical of all marvels, is persuaded that
the wonder has been fabricated by our honest woodman; until the parson,
a good historian, coming round that way, proclaims it a most interesting
circumstance, because it was one naturally to have been expected; for
that, here was the spot where, two hundred years ago, a great battle had
been fought: and it was no improbability at all that a carbine-bullet
should have penetrated a sapling, nor that the tree should thereafter
have grown old with the iron at its heart. How unreasonable then would
appear the pundit's incredulity, if persisted in: how suddenly
enlightened the rational faith of the rustic: how seasonable would be
felt the useful learning of him, whose knowledge well applied can thus
unfetter truth from the bandages of ignorance.

Illustrations, if apt, are so well adapted to persuade towards a
particular line of argument, that, at the risk of diffuseness, and
because minds being various are variously touched, one by one thought
and one by another, I think fit to add yet more of a similar tendency:
in the hope that, by a natural induction, such instances may smoothe our
way.
