ledge of real
Being and real Power, of an ultimate Reason and a personal Will, is
derived from the apperception of pure reason, which affirms the
necessary existence of a Supreme Reality--an Uncreated Being beyond all
phenomena, which is the ground and reason of the existence--the
contemporaneousness and succession--the likeness and unlikeness, of all
phenomena.

The immediate presentation of phenomena to sensation is the _occasion_
of the development in consciousness of these _a priori_ ideas of reason:
the possession of these ideas or the immanence of these ideas, in the
human intellect, constitutes the original _power_ to know external
phenomena. The ideas of space, time, power, law, reason, and end, are
the logical antecedents of the ideas of body, succession, event,
consecution, order, and adaptation. The latter can not be conceived as
distinct notions without the former. The former will not be revealed in
thought without the presentation to sense, of resistance, movement,
change, uniformity, etc. All actual knowledge must, therefore, be
impure; that is, it must involve both _a priori_ and _a posteriori_
elements; and between these elements there must be a necessary relation.

This necessary relation between the _a priori_ and _a posteriori_
elements of knowledge is not a mere subjective law of thought. It is
both a law of thought and a law of things. Between the _a posteriori_
facts of the universe and the _a priori_ ideas of the reason there is an
absolute nexus, a universal and necessary correlation; so that the
cognition of the latter is possible only on the cognition of the former;
and the objective existence of the realities, represented by the ideas
of reason, is the condition, _sine qua non_, of the existence of the
phenomena presented to sense. If, in one indivisible act of
consciousness, we immediately perceive extended matter exterior to our
percipient mind, then Extension exists objectively; and if Extension
exists objectively, then Space, its _conditio sine qua non_, also exists
objectively. And if a definite body reveals to us the _Space_ in which
it is contained, if a succession of pulsations or movements exhibit the
uniform _Time_ beneath, so do the changeful phenomena of the universe
demand a living _Power_ behind, and the existing order and regular
evolution of the universe presuppose _Thought_--prevision, and
predetermination, by an intelligent mind.

If, then, the universe is a created effect
