# Logic FAQs:

Q: Is logic examples of formal logic?

A: Yes.

Q: Is logic seen as complementary to Aristotle's treatment of rhetoric?

A: Yes.

Q: Is logic also the name given to the special treatment of dialectic in Hegelian and Marxist thought?

A: Yes.

Q: Is logic in large parts concerned with the theory of non-modalized logic?

A: Yes.

Q: Is logic normally formalized with the principle of the excluded middle?

A: Yes, and its relational semantics is bivalent, so this inclusion is disputable.

Q: Is logic an extension of symbolic logic into other areas?

A: Yes, and in particular to the study of model theory, proof theory, set theory, and recursion theory.

Q: Is logic the study of natural language arguments?

A: Yes.

Q: Is logic essential for the realist's understanding of how propositions are true of the world in just the same way as he has argued the principle of bivalence is?

A: Yes.

Q: Is logic essentially a continuation of the traditional discipline called "logic" before the invention of mathematical logic?

A: Yes.

Q: Is logic usually attributed to Gottlob Frege?

A: Yes, and who is also credited as one of the founders of analytical philosophy, but the formulation of predicate logic most often used today is the first-order logic presented in Principles of Mathematical Logic by David Hilbert and Wilhelm Ackermann in 1928.

Q: Is logic of great interest to computer scientists?

A: Yes, as it is a constructive logic and can be applied for extracting verified programs from proofs.

Q: Is logic commonly taught by university philosophy departments?

A: Yes, and often as a compulsory discipline.

Q: Is logic of essential importance to rationality?

A: Yes.

Q: Is logic most prominently defended by George Boolos and Stewart Shapiro?

A: Yes.

Q: Are logics those systems that reject various rules of Classical logic?

A: Yes.

Q: Is logic the study of a special kind of logical truth?

A: Yes, and arguing that instead one can talk of the logic of material inference , with logic making explicit the commitments that were originally implicit in informal inference.

Q: Is logic being applied to artificial intelligence?

A: Yes.

Q: Is logic the study of symbolic abstractions that capture the formal features of logical inference?

A: Yes.

Q: Is logic Latin?

A: Yes.

Q: Is logic the study of inference with purely formal content?

A: Yes.

Q: Was logic first developed by Aristotle?

A: Yes.

Q: Is logic has remained elusive?

A: Yes, and although the field of universal logic has studied the common structure of logics, in 2007 Mossakowski et al.

Q: Was logic developed by Avicenna?

A: Yes, and whom ultimately developed a theory of "temporally modalized" syllogistic.

Q: Is logic not truth conditional?

A: Yes, and so it has often been proposed as a non-classical logic.

Q: Was logic responsible for the introduction of hypothetical syllogism?

A: Yes, and temporal modal logic, and inductive logic, as well as influential terms such as terms, predicables, syllogisms and propositions.

Q: Is logic not seen as being in need of revolutionary solutions?

A: Yes.

Q: Is logic generally considered formal when it analyzes and represents the form of any valid argument type?

A: Yes.

Q: Is logic the most important approaches here?

A: Yes, though the concerns are different: a key consequence of classical logic and some of its rivals, such as intuitionistic logic, is that they respect the principle of explosion, which means that the logic collapses if it is capable of deriving a contradiction.

Q: Was logic proposed by L.E.J?

A: Yes, Brouwer as the correct logic for reasoning about mathematics, based upon his rejection of the law of the excluded middle as part of his intuitionism.

Q: Was logic second-order?

A: Yes, and rather than first-order.

Q: Is logic often divided into two main branches: propositional logic and predicate logic?

A: Yes.

Q: Is logic the generic term for symbolic formal systems such as first-order logic?

A: Yes, and second-order logic, many-sorted logic, and infinitary logic.

Q: Is logic extensively applied in the fields of Artificial Intelligence and Computer Science?

A: Yes, and these fields provide a rich source of problems in formal and informal logic.

Q: Is logic given by a mapping from terms to a universe of individuals, and a mapping from propositions to the truth values "true" and "false"?

A: Yes, Model-theoretic semantics is one of the fundamental concepts of model theory.

Q: Is logic not logic at all?

A: Yes.
