Ideas.



As the word _idea_ will frequently occur, and will be found
also to hold an important relation to our present subject, we shall
endeavour, _in limine_, to possess our readers of the particular
sense in which we understand and apply it.

An Idea, then, according to our apprehension, is the highest or most
perfect _form_ in which any thing, whether of the physical, the
intellectual, or the spiritual, may exist to the mind. By form, we do not
mean _figure_ or _image_ (though these may be included in relation to the
physical); but that condition, or state, in which such objects become
cognizable to the mind, or, in other words, become objects of
consciousness.

Ideas are of two kinds; which we shall distinguish by the terms _primary_
and _secondary_: the first being the _manifestation_ of objective
realities; the second, that of the reflex product, so to speak, of the
mental constitution. In both cases, they may be said to be
self-affirmed,--that is, they carry in themselves their own evidence;
being therefore not only independent of the reflective faculties, but
constituting the only unchangeable ground of Truth, to which those
faculties may ultimately refer. Yet have these Ideas no living energy in
themselves; they are but the _forms_, as we have said, through or in which
a higher Power manifests to the consciousness the supreme truth of all
things real, in respect to the first class; and, in respect to the second,
