conditional reasoning

Conditional reasoning is a type of deductive reasoning where a conclusion is drawn based on a conditional, or "if...then," proposition. This involves understanding the relationship between an antecedent (the "if" part) and a consequent (the "then" part).12

Valid inferences can be made through modus ponens (affirming the antecedent) and modus tollens (denying the consequent). For example, if "if it rains, the ground gets wet," and "it is raining," then "the ground gets wet" (modus ponens). Conversely, if "the ground is not wet," then "it is not raining" (modus tollens).1

Invalid inferences, known as fallacies, include "affirming the consequent" and "denying the antecedent". These occur when the logic does not hold, even if the premises seem plausible. The validity of conditional reasoning depends on its logical structure, not necessarily the truth of its content.1
