In philosophy, set of statements that makes intelligible the existence or occurrence of an object, event, or state of affairs. Among the most common forms of explanation are causal explanation (seecausation), deductive-nomological explanation (seecovering-law model), which involves subsuming the explanandum under a generalization from which it may be derived in a deductive argument (e.g., All gases expand when heated; this gas was heated; therefore, this gas expanded) and statistical explanation, which involves subsuming the explanandum under a generalization that gives it inductive support (e.g., Most people who use tobacco contract cancer; this person used tobacco; therefore, this person contracted cancer). Explanations of human behaviour typically appeal to the subject's beliefs and desires, as well as other facts about him, and proceed on the assumption that the behaviour in question is rational (at least to a minimum degree). Thus an explanation of why the subject removed his coat might cite the fact that the subject felt hot, that the subject desired to feel cooler, and that the subject believed that he would feel cooler if he took off his coat.
