This theory of deductive reasoning – also known as term logic – was developed by Aristotle, but was superseded by propositional (sentential) logic and predicate logic. [citation needed] Deductive reasoning can be contrasted with inductive reasoning, in regards to validity and soundness. In cases of inductive reasoning, even though the ...
A Mastermind player uses abduction to infer the secret colors (top) from summaries (bottom left) of discrepancies in their guesses (bottom right).. Abductive reasoning (also called abduction, [1] abductive inference, [1] or retroduction [2]) is a form of logical inference that seeks the simplest and most likely conclusion from a set of observations.
Inductive reasoning is any of various methods of reasoning in which broad generalizations or principles are derived from a body of observations. [1] [2] This article is concerned with the inductive reasoning other than deductive reasoning (such as mathematical induction), where the conclusion of a deductive argument is certain given the premises are correct; in contrast, the truth of the ...
There are various types of non-deductive reasoning, like inductive, abductive, and analogical reasoning. [1] [59] Non-deductive reasoning is more common in everyday life than deductive reasoning. [60] Non-deductive reasoning is ampliative and defeasible.
Other forms of reasoning are sometimes also taken to be part of logic, such as inductive reasoning and abductive reasoning, which are forms of reasoning that are not purely deductive, but include material inference. Similarly, it is important to distinguish deductive validity and inductive validity (called "strength").
Scientists use inductive reasoning to create theories and hypotheses. [29] Philip Johnson-Laird distinguished inductive from deductive reasoning, in that the former creates semantic information while the later does not . [27]: 439 In opposition, deductive reasoning is a basic form of valid reasoning. [29]

Reasoning may be subdivided into forms of logical reasoning, such as deductive reasoning, inductive reasoning, and abductive reasoning. Aristotle drew a distinction between logical discursive reasoning (reason proper), and intuitive reasoning , [ 6 ] : VI.7 in which the reasoning process through intuition—however valid—may tend toward the ...
