Logic is the study of correct Logical reasoning, reasoning. It includes both Logic#Formal logic, formal and informal logic. Formal logic is the study of Validity (logic), deductively valid inferences or logical truths. It examines how conclusions follow from premises based on the structure of arguments alone, independent of their topic and content. Informal logic is associated with informal fallacies, critical thinking, and argumentation theory. Informal logic examines arguments expressed in natural language whereas formal logic uses formal language. When used as a countable noun, the term "a logic" refers to a specific logical formal system that articulates a proof system. Logic plays a central role in many fields, such as philosophy, mathematics, computer science, and linguistics. Logic studies arguments, which consist of a set of premises that leads to a conclusion. An example is the argument from the premises "it's Sunday" and "if it's Sunday then I don't have to work" le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Modus Ponendo Ponens
In propositional calculus, propositional logic, (; MP), also known as (), implication elimination, or affirming the antecedent, is a Deductive reasoning, deductive argument form and rule of inference. It can be summarized as "''P'' material conditional, implies ''Q.'' ''P'' is true. Therefore, ''Q'' must also be true." ''Modus ponens'' is a mixed hypothetical syllogism and is closely related to another Validity (logic), valid form of argument, ''modus tollens''. Both have apparently similar but invalid forms: affirming the consequent and denying the antecedent. Constructive dilemma is the Logical disjunction, disjunctive version of ''modus ponens''. The history of ''modus ponens'' goes back to Classical antiquity, antiquity. The first to explicitly describe the argument form ''modus ponens'' was Theophrastus. It, along with ''modus tollens'', is one of the standard patterns of inference that can be applied to derive chains of conclusions that lead to the desired goal. Exp ...
