Various, The Southern Literary Messenger…
“ Undoubtedly one of the greatest and most useful powers of the human mind, is that by which we are enabled to classify and generalize our ideas—that power which enables us, from the observance of multitudes of facts and details, to seize on those which possess a resemblance, to arrange them together under genera and species, and thus to arrive at general principles or facts applicable to thousands of cases which may occur in our passage through life. It is this power of abstraction and generalization which may be truly said to give to our reasoning faculties the wings of the eagle. ”
