Specifically, Kant states that "a mind of slow apprehension is therefore not necessarily a weak mind" since "the one who is alert with abstractions is not always profound" but "is more often very superficial." He argues, "[t]he deceiver is really the fool." On determination and mental resolve, in addition, Kant asserts that "[t]hrough failures one becomes intelligent" and "the one who has trained himself in this subject so that he can make others wise through their own failures... [thus] has used his intelligence."
