To this vital question upon which so much of human life and happiness depends, the weak and degrading answer must suffice; to the effect that the last vestige of public respect for the sciences would be shaken, and many wise theories would fail of their imaginary virtues and succumb, before humanity's best birthright--the quality of healthy blood, kind nature's ample gift to all,--could be wrested from the selfish hand of tyranny and mankind enabled to secure from nature's willing hand the succour that an Infinite Providence offers to disease. A physician to whom I once explained my theories, heard me for some minutes and then he said "Well, and so you want to create healthy blood in this way?" "Yes, surely," I replied. "We have no use for that," he callously exclaimed, "there would _be no business in that_." _Hence Mankind must degenerate and Disease of all kinds ride rampant_ through the land, rather than upset the firmly rooted fallacies of the past or foil the ghoul-like greed of a certain set of conscienceless practitioners. To the first of these the terse old Latin satire would apply: "Homine imperito nunquam quidquam injustius Qui, nisi quod ipse fecit, nihil rectum putat." (Terentius.) "Who is there so unreasoning as he, that learned drone, Who reckons nothing perfect save what he himself hath known." (M.B.) To the second let an outraged public reply. * * * * * But meanwhile, as the hideous holocaust proceeds, the mills of God grind slowly but mysteriously secure. The eternal law of equity is working still; and from every evil there proceeds a good. Truth may be hidden in the nether deeps, but some day the strained tension breaks, the balance reversing brings it to the light. Its spirit works for ever, like a ferment, hidden long, deep down in the Universal heart of things; for with majestic, unimpressionable tread, sublimely the silent force of human progress moves; slow and inevitably sure, the great indwelling spirit of a vast eternal energy leading man ever upward to the True and Best. Against this axiom, alas, graceless and suicidal seems the unwisdom of the world, in action against all who offer it salvation from its pain; aye, though he be Christ or Commoner. Rather be wrong in league with wealth and power than be right--and stand alone. This is now the worldly wisdom of the sage. Genius at grips with material and religious power, fares ill; as with far-famed Copernicus, or "starry Galileo and his woes"; or, in a brave woman's daring words:--"He, who dares to see a truth not recognized in creeds, must die the death."
