BUFFALO LOGIC COLLOQUIUM
2006-7 THIRTY-SEVENTH YEAR
FOURTH FALL ANNOUNCEMENT
QUOTES OF THE MONTH: LEWIS ON MATHEMATICAL SYSTEMS: A mathematical
system is any set of strings of recognizable marks in which some of the
strings are taken initially and the remainder derived from these by
operations performed according to rules which are independent of any
meaning assigned to the marks. C. I. Lewis, 1918, 355. TARSKI ON FORMAL
LANGUGES: We are not interested here in formal languages to the
expressions of which no meaning is attached. For such languages the
problem here discussed has no relevance, it is not even meaningful.
Tarski 1933/1956, 166. CORCORAN ON LEWIS, TARSKI, AND ZOMBIES. Is it
an exquisite irony that 15 years later Tarski published a completely
meaningful axiomatization of string theory, a theory about possibly
meaningless strings? And in the same paper he made the concept of truth
respectable and saved logic from the skeptics and the zombies. John

TITLE: De Morgans Ways of Construing the Syllogism.
ABSTRACT: Augustus De Morgan's logical work seems to have been
constrained by a fixation on tinkering with the traditional syllogism.
Nevertheless, he introduced three logical innovations which go far
beyond the syllogism. What is notable is that the syllogism emerges as a
special case of each approach and that each ends up construing the
syllogism in a different way. The three innovations are: the logic of
complex terms (Boolean algebra), the numerically definite syllogism, and
the logic of relations. All are found in his FORMAL LOGIC (1847), though
the logic of relations is only developed fully later on. This talk will
outline the innovations, and discuss critically the ways in which De
Morgan embeds the traditional syllogism within them.
Dutch treat supper 6:30 pm at the Family Tree.
