PROP. XVIII.————

Eighteenth counter-proposition.nothing but the relative in cognition: in other words, the relative, and the relative only, is known or knowable by man."

It is shown to be contradictory.4. The test of this counter-proposition is the definition just given of the relative. The relative can be known only along with its correlative: therefore to affirm that the relative only can be known, is to affirm that the relative can be known without its correlative being known, which, of course, is a contradictory assertion. What further fallacies lurk under this counter-proposition, and arise out of it, shall be exposed in the subsequent articles.
