Philosophical Works of the Late James Frederick Ferrier
(1875)
“ Ontology, or the science of true Being, undertakes to demonstrate what true Being is, what alone absolutely exists. But our ignorance being, beyond all question, excessive, we must get the ontological demonstration into such a shape that we shall be able to affix the same predicate to absolute existence—to declare with certainty what it is, whether we suppose ourselves to know it, or to be ignorant of it. By working the system into such a shape that the result is the same on either alternative, a valid ontology may be constructed. ”
