science in every stage provokes, and in none more than in the earliest. Or, if he retires as from a scene of contest that he had not anticipated, he retires as one confessing a human precipitance and a human oversight, weaknesses, venial in others, but fatal to the pretensions of a divine teacher. Starting besides from such pretensions, he could not (as others might) have the privilege of selecting arbitrarily or partially. If upon one science, then upon all,--if upon science, then upon, art,--if upon art and science, then upon _every_ branch of social economy, upon _every_ organ of civilization, his reformations and advances are equally due; due as to all, if due as to any. To move in one direction, is constructively to undertake for all. Without power to retreat, he has thus thrown the intellectual interests of his followers into a channel utterly alien to the purposes of a spiritual mission. Thus far he has simply failed: but next comes a worse result; an evil, not negative but positive. Because, _thirdly_, to apply the light of a revelation for the benefit of a merely human science, which is virtually done by so applying the illumination of an _inspired_ teacher, is--to assault capitally the scheme of God's discipline and training for man. To improve by _heavenly_ means, if but in one solitary science--to lighten, if but in one solitary section, the condition of difficulty which had been designed for the strengthening and training of human faculties, is _pro tanto_ to disturb--to cancel--to contradict a previous purpose of God, made known by silent indications from the beginning of the world. Wherefore did God give to man the powers for contending with scientific difficulties? Wherefore did he lay a secret train of continual occasions, that should rise, by intervals, through thousands of generations, for provoking and developing those activities in man's intellect, if, after all, he is to send a messenger of his own, more than human, to intercept and strangle all these great purposes? When, therefore, the persecutors of Galileo, alleged that Jupiter, for instance, could not move in the way alleged, because then the Bible would have proclaimed it,--as they thus threw back upon God the burthen of discovery, which he had thrown upon Galileo, why did they not, by following out their own logic, throw upon the Bible the duty of discovering the telescope, or discovering the satellites of Jupiter? And, as no such discoveries were there, why did they not, by parity of logic, and for mere consistency, deny the telescope as a fact, deny the Jovian planets as facts? But this it is to mistake the very meaning and purposes of a revelation. A revelation is not made for the purpose of showing to idle men that which they may show to themselves, by faculties already given to them, if only they will exert those faculties, but for the purpose of showing _that_ which the moral darkness of man will not, without supernatural light, allow him to perceive.
