Hamilton, professor of logic in the University of Edinburgh, has not hesitated to adopt the conclusions of our discussion, to which he is pleased to refer his readers:--Discussions on Philosophy and Literature, etc._, by Sir William Hamilton, London, 1852. Appendix I, p. 588.

Oeuvres de Reid, vol. iv., p. 435. "When we revolt against primitive facts, we equally misconceive the constitution of our intelligence and the end of philosophy. Is explaining a fact any thing else than deriving it from another fact, and if this kind of explanation is to terminate at all, does it not suppose facts inexplicable? The science of the human mind will have been carried to the highest degree of perfection it can attain, it will be complete, when it shall know how to derive ignorance from the most elevated source."
