This said, it should be made clear in what sense the word "metaphysics" is used, all the more so since I have frequently had occasion to state that everyone does not understand it in the same way. I think the best course to take with words that can give rise to ambiguity is to reduce them, as far as possible, to their primary and etymological meaning. Now, according to its composition, this word "metaphysics" means literally "beyond physics," taking the word "physics" in the accepted meaning it always had for the ancients, that is, as the science of nature in its widest sense. Physics is the study of all that appertains to the domain of nature; metaphysics, on the other hand, is the study of what lies beyond nature. How, then, can some claim that metaphysical knowledge is natural knowledge, either in respect of its object or with regard to the faculties by which it is obtained? There we have a complete misconception, a contradiction in terms; and what is more amazing, this confusion affects even those who should preserve some idea of the true metaphysics and know how to distinguish it clearly from the pseudometaphysics of modern philosophers.
