The sum total of moral philosophy is found in this one question, Is Good a superfluous word,—or mere lazy synonyme for the pleasurable, and its causes;—at most, a mere modification to express degree, and comparative duration of pleasure?—Or the question may be more unanswerably stated thus, Is good superfluous as a word exponent of a kind?—If it be, then moral philosophy is but a subdivision of physics. If not, then the writings of Paley and all his predecessors and disciples are false and most pernicious; and there is an emphatic propriety in the superlative, and in a sense which of itself would supply and exemplify the difference between most and very.

MORAL LAW OF POLARITY.

It is curious to trace the operation of the moral law of polarity in the history of politics, religion, &c. When the maximum of one tendency has been attained, there is no gradual decrease, but a direct transition to its minimum, till the opposite tendency has attained its maximum; and then you see another corresponding revulsion. With the Restoration came in all at once the mechanico-corpuscular philosophy, which, with the increase of manufactures, trade, and arts, made every thing in philosophy, religion, and poetry objective; till, at length, attachment to mere external worldliness and forms got to its maximum,—when out burst the French revolution; and with it every thing became immediately subjective, without any object at all. The Rights of Man, the Sovereignty of the People, were subject and object both. We are now, I think, on the turning point again. This Reform seems the ne plus ultra of that tendency of the public mind which substitutes its own undefined notions or passions for real objects and historical actualities. There is not one of the ministers—except the one or two revolutionists among them—who has ever given us a hint, throughout this long struggle, as to what he really does believe will be the product of the bill; what sort of House of Commons it will make for the purpose of governing this empire soberly and safely. No; they have actualized for a moment a wish, a fear, a passion, but not an idea.

EPIDEMIC DISEASE.—QUARANTINE.

There are two grand divisions under which all contagious diseases may be classed:—1. Those which spring from organized living beings, and from the life in them, and which enter, as it were, into the life of those in whom they reproduce themselves—such as small-pox and measles. These become so domesticated with the habit and system, that they are rarely received twice. 2. Those which spring from dead organized, or unorganized matter, and which may be comprehended under the wide term malaria.

You may have passed a stagnant pond a hundred times without injury: you happen to pass it again, in low spirits and chilled, precisely at the moment of the explosion of the gas: the malaria strikes on the cutaneous or veno-glandular system, and drives the blood from the surface; the shivering fit comes on, till the musculo-arterial irritability re-acts, and then the hot fit succeeds; and, unless bark or arsenic—particularly bark, because it is a bitter as well as a tonic—be applied to strengthen the veno- glandular, and to moderate the musculo-arterial, system, a man may have the ague for thirty years together.

But if, instead of being exposed to the solitary malaria of a pond, a man, travelling through the Pontine Marshes, permits his animal energies to flag, and surrenders himself to the drowsiness which generally attacks him, then blast upon blast strikes upon the cutaneous system, and passes through it to the musculo-arterial, and so completely overpowers the latter that it cannot re-act, and the man dies at once, instead of only catching an ague.

There are three factors of the operation of an epidemic or atmospheric disease. The first and principal one is the predisposed state of the body; secondly, the specific virus in the atmosphere; and, thirdly, the accidental circumstances of weather, locality, food, occupation, &c. Against the second of these we are powerless: its nature, causes, and sympathies are too subtle for our senses to find data to go upon. Against the first, medicine may act profitably. Against the third, a wise and sagacious medical police ought to be adopted; but, above all, let every man act like a Christian, in all charity, and love, and brotherly kindness, and sincere reliance on God's merciful providence.
