The term dilemma is attributed by Gabriel Nuchelmans to Lorenzo Valla in the 15th century, in later versions of his logic text traditionally called Dialectica. Valla claimed that it was the appropriate Latin equivalent of the Greek dilemmaton. Nuchelmans argued that his probable source was a logic text of c. 1433 of George of Trebizond. [2]
'The problem of demarcation' is an expression introduced by Karl Popper to refer to 'the problem of finding a criterion which would enable us to distinguish between the empirical sciences on the one hand, and mathematics and logic as well as "metaphysical" systems on the other'.
Various logical formal systems or logics have been developed in the 20th century and it is the task of the philosophy of logic to classify them, to show how they are related to each other, and to address the problem of how there can be a manifold of logics in contrast to one universally true logic.
Carneades could be the true author of the paradox attributed to Epicurus.. There is no text by Epicurus that confirms his authorship of the argument. [3] Therefore, although it was popular with the skeptical school of Greek philosophy, it is possible that Epicurus' paradox was wrongly attributed to him by Lactantius who, from his Christian perspective, while attacking the problem proposed by ...
In this sense, it forms one area of the philosophy of logic. [1] Central to philosophical logic is an understanding of what logic is and what role philosophical logics play in it. Logic can be defined as the study of valid inferences. [4] [6] [9] An inference is the step of reasoning in which it moves from the premises to a conclusion. [10]
Constructive dilemma [1] [2] [3] is a valid rule of inference of propositional logic. It is the inference that, if P implies Q and R implies S and either P or R is true, then either Q or S has to be true. In sum, if two conditionals are true and at least one of their antecedents is, then at least one of their consequents must be too.
A dilemma, which is Greek for "two premises", has been likened to the front end of an angry and charging bull. Phædrus, however, because of his training in logic, was aware that every dilemma affords not two but three classic refutations, and he also knew of a few that weren't so classic... He could take the left horn ....
Logic and rationality have each been taken as fundamental concepts in philosophy. They are not the same thing. Philosophical rationalism in its most extreme form is the doctrine that knowledge can ultimately be founded on pure reason, while logicism is the doctrine that mathematical concepts, among others, are reducible to pure logic.
