with propriety." Those who _think_, will demand the _meaning_ of these
words, and the reason of their use. When that is ascertained, little
difficulty will be found in giving them a place in the company of
respectable words. But I am digressing. More shall be said upon this
point in a future lecture, and in its proper place.

I was endeavoring to establish the position that all language depends
upon permanent principles; that words are the signs of ideas, and ideas
are the impressions of things communicated to the mind thro the medium
of some one of the five senses. I think I have succeeded so far as
simple material things are concerned, to the satisfaction of all who
have heard me. It may, perhaps, be more difficult for me to explain the
words employed to express complex ideas, and things of immateriality,
such as mind, and its attributes. But the rules previously adopted will,
I apprehend, apply with equal ease and correctness in this case; and we
shall have cause to admire the simple yet sublime foundation upon which
the whole superstructure of language is based.

In pursuing this investigation I shall endeavor to avoid all abstruse
and metaphysical reasoning, present no wild conjectures, or vain
hypotheses; but confine myself to plain, common place matter of fact. We
have reason to rejoice that a wonderful improvement in the science and
cultivation of the mind has taken place in these last days; that we are
no longer puzzled with the strange phantoms, the wild speculations which
occupied the giant minds of a Descartes, a Malebranch, a Locke, a Reid,
a Stewart, and hosts of others, whose shining talents would have
qualified them for the brightest ornaments of literature, real
benefactors of mankind, had not their education lead them into dark and
metaphysical reasonings, a continued tissue of the wildest vagaries, in
which they became entangled, till, at length, they were entirely lost in
