§ 5. De Morgan.

Of these mathematicians, Augustus De Morgan was the oldest. He was educated at Cambridge, but, at that time, office in the university was conditional on certain declarations of religious belief. In consequence of this, he moved to London, and there, through his writings and lectures, exercised wide influence. He was well read in the philosophy and history of mathematics; but it is on the general influence he exerted rather than on discoveries of his own that his reputation rests. With his name we may associate that of George Boole, of Cork, the creator of certain branches of symbolic logic, whose mathematical works are enriched by discussions on the fundamental principles of the subject. His writings are valuable in themselves and their presentment of conclusions is lucid and interesting.
