effects are so near akin, that we do not stop to measure even the wide
degrees by which they are marked, but class them in a breath by some
common term. It is very plain that this singular property of
assimilating to one what is so widely unlike cannot proceed from any
similar conformation, or quality, or attribute of mere being, that is,
of any thing essential to distinctive existence. There must needs, then,
be some common ground for their common effect. For if they agree not in
themselves one with the other, it follows of necessity that the ground
of their agreement must be in relation to something within our own
minds, since only _there_ is this common effect known as a fact.

We are now brought to the important question, _Where_ and
_what_ is this reconciling ground? Certainly not in sensation,
for that could only reflect their distinctive differences. Neither can
it be in the reflective faculties, since the effect in question, being
co-instantaneous, is wholly independent of any process of reasoning;
for we do not feel it because we understand, but only because we are
conscious of its presence. Nay, it is because we neither do nor can
understand it, being therefore a matter aloof from all the powers of
reasoning, that its character is such as has been asserted, and, as
such, universal.

Where, then, shall we search for this mysterious ground but in the
mind, since only there, as before observed, is this common effect
known as a fact? and where in the mind but in some inherent Principle,
which is both intuitive and universal, since, in a greater or less
degree, all men feel it _without knowing why?_

But since an inward Principle can, of necessity, have only a potential
existence, until called into action by some outward object, it is also
