Originally published in 1966 On the Syllogism and Other Logical Writings assembles for the first time the five celebrated memoirs of Augustus De Morgan on the syllogism. These are collected together with the more condensed accounts of his researches given in his Syllabus of a Proposed System of Logic an article on Logic contributed to the English Cyclopaedia. De Morgan was among the most distinguished of nineteenth century British mathematicians but is chiefly remembered today as one of the founders of modern mathematical logic. His writings on this subject have been little read, however since apart from his Formal Logic, they lie buried for the most part in inaccessible periodicals. De Morgan's own later amendments are inserted in the text and the editorial introduction gives a summary of the whole and traces in some detail the course of the once-famous feud with Sir William Hamilton of Edinburgh.

One of the twentieth century's most eminent mathematical writers, Augustus De Morgan enriched his expositions with insights from history and psychology. On the Study and Difficulties of Mathematics represents some of his best work, containing points usually overlooked by elementary treatises, and written in a fresh and natural tone that provides a refreshing contrast to the mechanical character of common textbooks. Presuming only a knowledge of the rules of algebra and Euclidean theorems, De Morgan begins with some introductory remarks on the nature and objects of mathematics. He discusses the concept of arithmetical notion and its elementary rules, including arithmetical reactions and decimal fractions. Moving on to algebra, he reviews the elementary principles, examines equations of the first and second degree, and surveys roots and logarithms. De Morgan's book concludes with an exploration of geometrical reasoning that encompasses the formulation and use of axioms, the role of proportion, and the application of algebra to the measurement of lines, angles, the proportion of figures, and surfaces.

The fame of Augustus De Morgan (1806-1871), a brilliant mathematician and logician, has been eclipsed by that of his son, the celebrated ceramicist William De Morgan. However, as readers of his Memoir will discover, De Morgan senior enjoyed an equally distinguished, if turbulent, career. Collated by his wife, and published in 1882, nine years after his death, the Memoir of Augustus de Morgan chronicles the varied life of an under-appreciated genius. Biographical narrative is interleaved with his own correspondence, revealing a humorous and warm personality as well as an exceptional intellect. As the Pall Mall Gazette told its readers, 'quaint and original to the last, every word of De Morgan's correspondence is well worth reading'. Although rich in detail about his work and publications, Sophia Elizabeth's affectionate account of her husband is also sympathetic and witty, making it an ideal introduction to one of Britain's greatest minds.
