 Analytic explanations are common in the currents of daily life, especially in the context of explaining how you “know that” something is the case. A mother might explain to her single daughter that she knows that John must be unmarried, because a friend told her that John is a bachelor. Similar cases of analytic explanations can occur in scientific contexts, such as knowing that the element they are dealing with is gold because it has atomic number 79, when gold is defined by its atomic number. Knowing why John is a bachelor, however, is another matter. Indeed, in Hempel (1965c), he would distinguish between reason-seeking why-questions and explanation-seeking why-questions, where the former seek reasons that justify believing that something is the case, as opposed to the latter, which are usually motivated by knowledge that a specific event has occurred.
