Another abuse of language is an AFFECTED OBSCURITY; by either applying old words to new and unusual significations; or introducing new and ambiguous terms, without defining either; or else putting them so together, as may confound their ordinary meaning.

Though the Peripatetick philosophy has been most eminent in this way, yet other sects have not been wholly clear of it.

There are scarce any of them that are not cumbered with some difficulties (such is the imperfection of human knowledge,) which they have been fain to cover with obscurity of terms, and to confound the signification of words, which, like a mist before people's eyes, might hinder their weak parts from being discovered.

That BODY and EXTENSION in common use, stand for two distinct ideas, is plain to any one that will but reflect a little.

For were their signification precisely the same, it would be as proper, and as intelligible to say, 'the body of an extension,' as the 'extension of a body;' and yet there are those who find it necessary to confound their signification.
