William Frend De Morgan artist, novelist, b. The followers of Aristotle say that from two particular propositions such as Some M's are A'sand Some M's are B's nothing follows of necessity about the relation of the A's and B's.
John De Morgan d. A body of liberal-minded men resolved to meet the difficulty by establishing in London a University on the principle of religious neutrality. The general character of De Morgan's development of logical forms was wholly peculiar and original on his part.
His mathematical talents went unnoticed until he was fourteen, when a family-friend discovered him making an elaborate drawing of a figure in Euclid with ruler and compasses. The last two may be called the rules of reduction.
This contains a reprint of the First Notions, an elaborate development of his doctrine of the syllogism, and of the numerical definite syllogism, together with chapters of great interest on probability, induction, old logical terms and fallacies.
Ferguson, but the plan was developed by one who was an unrivalled master of all the intricacies of chronology. The following is a specimen: Death and Legacy De Morgan suffered the loss of two of his children one of whom was his son who was also an aspiring mathematician.
This algebra was extended by Charles Sanders Peirce who admired De Morgan and met him shortly before his deathand re-exposited and further extended in vol. In he introduced and defined the term mathematical induction to describe the process that until then had been used with little clarity in mathematical proofs.
I use the word in the old sense: He had 3 sons and 4 daughters. His mode of reasoning was a curious caricature of the reductio ad absurdum of Euclid. The following is a specimen of De Morgan's dragging round the walls of Troy: University education Inat the age of sixteen, he entered Trinity College, Cambridge where he came under the influence of George Peacock and William Whewellwho became his life-long friends; from the former he derived an interest in the renovation of algebra, and from the latter an interest in the renovation of logic—the two subjects of his future life work.
Second and third editions were called for in and ; a sixth edition was issued in De Morgan was full of personal peculiarities.
In spite, however, of the excellence and extent of his mathematical writings, it is probably as a logical reformer that De Morgan will be best remembered. Helen Christina De Morgan b.
During this period, he also promoted the work of self-taught Indian mathematician Ramchundrawho has been called De Morgan's Ramanujam. It is perfectly good English to use the same word in two different senses in one sentence, particularly when there is usage.
A layman of the school of Bain and Spencer was appointed. To the formalists the index operations are exceedingly refractory, in consequence of which some take no account of them, but relegate them to applied mathematics. He once printed his name: Every term is distinctly explained, and has but one meaning, and it is rarely that two words are employed to mean the same thing.
He recognised the purely symbolic nature of algebra and he was aware of the existence of algebras other than ordinary algebra. This gives confidence, and is absolutely necessary, if, as was said before, reason is not to be the instructor, but the pupil.
His love of knowledge for its own sake interfered with training for the great mathematical race; as a consequence he came out fourth wrangler.
The two ancient universities of Oxford and Cambridge were so guarded by theological tests that no Jew or Dissenter outside the Church of England could enter as a student, still less be appointed to any office.
De Morgan was a highly successful teacher of mathematics. De Morgan admits that there is one exception; but an exception proves the rule, not in the usual but illogical sense of establishing it, but in the old and logical sense of testing its validity.
In his time there flourished two Sir William Hamiltons who have often been confounded. The London University was affiliated as a teaching college with the University of London, and its name was changed to University College.
Asserting that logic as it had come down from Aristotle was unnecessarily restricted in scope, De Morgan made his greatest contributions as a reformer of logic.
