on
Avoiding logical determinism and retaining the principle of bivalence
within a tense-modal logic system
 
Tuesday, 5 October, 2010, 4.30 PM, Zrinyi 14, Room 412
 
ABSTRACT
 
Jan Lukasiewicz was the first logician in the history of modern logic
who has become completely aware of the fact that Aristotle’s reasoning
related to his famous future see battle example does not undermine so
much the principle of the excluded middle but, in the first place, the
principle of bivalence.. In order to avoid such a kind of determinism,
later called logical determinism, Lukasiewicz introduced many-valued
logic. So, in the trivalent system, a sentence can happen to be neither
true nor false at a given time. It is so if, at that time, there is
nothing in reality that makes it true or false. Its truth value is
indeterminate.
I shall show how, by using the possible world semantics of contemporary
modal logic, it is possible to avoid logical determinism and, at the
same time, retain the principle of bivalence.
