not men's opinions thereon, that is of importance); but also because it would be like _γλαύκας εἰς 'Aθήνας κομίζειν_ (_i.e._, carrying coals to Newcastle); for previous attempts to give a foundation to Ethics are sufficiently well-known to the Royal Society, and the very question proposed shows that it is also convinced of their inadequateness. Any reader less well-informed will find a careful, if not complete, presentment of the attempts hitherto made, in Garve's _Uebersicht der vornehmsten Principien der Sittenlehre_, and again, in Stäudlin's _Geschichte der Moralphilosophie._ It is of course very disheartening to reflect that Ethics, which so directly concerns life, has met with the same unhappy fate as the abstruse science of Metaphysics, and that its first principle, though perpetually sought for ever since the time of Socrates, has still to be found. Moreover, we must remember that in Ethics, much more than in any other science, what is essential is contained in its fundamental propositions; the deductions are so simple that they come of themselves. For all are capable of drawing a conclusion, but few of judging. And this is exactly the reason why lengthy text-books and dissertations on Morals are as superfluous as they are tedious. Meantime, if I may postulate an acquaintance with all the former foundations of Ethics, my task will be lightened. Whoever observes how ancient as well as modern philosophers (the Church creed sufficed for the middle ages) have had recourse to the most diverse and extraordinary arguments, in order to provide for the generally recognised requirements of morality a basis capable of proof, and how notwithstanding they admittedly failed; he will be able to measure the difficulty of the problem, and estimate my contribution accordingly. And he who has learned to know that none of the roads hitherto struck on lead to the goal, will be the more willing to tread with me a very different path from these--a path which up to now either has not been noticed, or else has been passed over with contempt; perhaps because it was the most natural one.[1] As a matter of fact my solution of the question will remind many of Columbus' egg.
