1The rule of logic which states that if a conditional statement (‘if p then q’) is accepted, and the antecedent (p) holds, then the consequent (q) may be inferred.
‘He maintained that these methodological principles underlie evaluative practice in science just as modus ponens underlies deductive inference.’
‘The statement that q follows by modus ponens from the other two stated as known in the antecedent of the subjunctive principle P; this principle counts on the person to draw the inference to q.’
‘It could be a premise either, as some say, as the premise of a propositional scheme such as the modus ponens, or, as others assume, as the conditional premise of a hypothetical syllogism.’
‘From a conditional statement, one can construct two types of valid inference: modus ponens and modus tollens.’
‘We also noted that one of the most fundamental inferences concerning the conditional is modus ponens: a, a c c.’
‘This formal fallacy is often mistaken for modus ponens, a valid form of reasoning also using a conditional.’
1.1An argument using the rule of modus ponens.
‘Consider, for example, propositional logic: here one can start from self-evident axioms and proceed to deduce theorems by argument forms - modus ponens, for example - that are themselves self-evidently valid in an obvious sense.’
‘Robustness was meant to ensure that an assertable conditional is fit for modus ponens.’
‘The first three points are a valid form of argument, in the form of modus ponens.’
