George Boole (1815-1864) is well known to mathematicians for his
research and textbooks on the calculus, but his name has spread
world-wide for his innovations in symbolic logic and the development and
applications made since his day. The utility of "Boolean algebra" in
computing has greatly increased curiosity in the nature and extent of
his achievements. His work is most accessible in his two books on logic,
"A mathematical analysis of logic" (1947) and "An investigation of the
laws of thought" (1954). But at various times he wrote manuscript
essays, especially after the publication of the second book; several
were intended for a non-technical work, "The Philosophy of logic", which
he was not able to complete. This volume contains an edited selection
which not only relates them to Boole's publications and the historical
context of his time, but also describes their strange history of family,
followers and scholars have treid to confect an edition. The book will
appeal to logicians, mathematicians and philosophers, and those
interested in the histories of the corresponding subjects; and also
students of the early Victorian Britain in which they were written.
