George Stuart Fullerton,
A Handbook of Ethical Theory
“ A man may be possessed of great intelligence; he may be well-informed, acute in his reasonings, and consistent in his strivings to attain some comprehensive end, which, on the whole, appears congruous to his nature, such as it is. Yet we may regard him as highly unreasonable. Judged by some higher standard which we look upon as approved by reason, he is found to fall short. Is reason, then, synonymous with intelligence? Or is it something more—the source of an ultimate standard of action, intuitively known, and by which all man's actions must be judged? ”
