Note 3 — LECTURE II.
Reading edition
Metaphysics originally signified the science of the causes and principles of all things. Afterwards it was confined to the philosophy of the mind. In our times it has obtained still another meaning. Metaphysicians became so abstruse, bewildered, and lost, that nobody could understand them; and hence, metaphysical is now applied to whatever is abstruse, doubtful, and unintelligible. If a speaker is not understood, it is because he is too metaphysical. "How did you like the sermon, yesterday?" "Tolerably well; but he was too metaphysical for common hearers." They could not understand him.
