Lord Bacon has set down the abuse, of which I am speaking, among the impediments to the Advancement of the Sciences, when he observes that “men have used to infect their meditations, opinions, and doctrines, with some conceits which they have most admired, or _some Sciences which they have most applied_; and give all things else a _tincture_ according to them _utterly untrue and improper_.…” So have the alchemists made a philosophy out of a few experiments of the furnace; and Gilbertus, our countryman, hath made a philosophy out of the observations of a lodestone. So Cicero, when, reciting the several opinions of the nature of the soul, he found a musician that held the soul was but a harmony, saith pleasantly, “hic ab arte suâ non recessit,” “he was true to his art.” But of these conceits Aristotle speaketh seriously and wisely when he saith, “Qui respiciunt ad pauca, de facili pronunciant,” “they who contemplate a few things have no difficulty in deciding.” 5. And now I have said enough to explain the inconvenience which I conceive necessarily to result from a refusal to recognize theological truth in a course of Universal Knowledge;—it is not only the loss of Theology, it is the perversion of other sciences. What it unjustly forfeits, others unjustly seize. They have their own department, and, in going out of it, attempt to do what they really cannot do; and that the more mischievously, because they do teach what in its place is true, though when out of its place, perverted or carried to excess, it is not true. And, as every man has not the capacity of separating truth from falsehood, they persuade the world of what is false by urging upon it what is true. Nor is it open enemies alone who encounter us here, sometimes it is friends, sometimes persons who, if not friends, at least have no wish to oppose Religion, and are not conscious they are doing so; and it will carry out my meaning more fully if I give some illustrations of it.
