We may see the truth, once again, in the acknowledged instability of the passional element in human nature--particularly in man. It is nothing short of amazing to see this very instability urged as a reason why the marriage tie should be still further weakened, as though man should deliberately subject himself to the vagaries of sense, instead of the guidance of reason. We hear much to-day about the "return to nature," and, soundly interpreted, that gospel sounds like a breath of pure mountain air after the stifling atmosphere of modern convention and unreality. Would to heaven, I say from my heart, that we were more natural, that a greater frankness and directness marked our intercourse with one another, that the shams and pretences of so much of our social life were made away with, that our lives were more open and free! The grand old Stoic maxim had it thus: _Live in accordance with nature_. Yes, but with what nature? No thinker, from Socrates to Kant, from Buddha to Hegel, ever had a doubt but that man's nature was twofold, and that the law of reason must be supreme in him. Let an animal live for sense; it is its nature; but for man another law is ordained, which bids him think last of enjoyment, and to partake only of that in obedience to the law of the mind. The modern evangel of the apotheosis of the unstable we understand to convey the teaching, "Live in accordance with sense, or the feeling of the moment". Be like the _dame du monde_ whom Mrs. Ward has so accurately drawn in _Madame de Netteville_, who did not hold herself responsible to our petty codes, and judged that feeling was guidance enough for her. That may be all very well for Madame de Netteville, but how does such teaching look in the light of Kant's solemn injunction: "Act so that thy conduct may become a law unto all men"? Could any one seriously propose to erect feeling into a supreme criterion whereby to judge of the conduct of life? And, to show that the line of argument here adopted is no mere false asceticism surviving from an undisciplined and pre-scientific age, as the solemn verbiage of so much second-rate talking expresses it to-day, we may quote some words of David Hume, Huxley's "prince of agnostics," from the _Essay on Polygamy and Divorce_. The least emotional of philosophers--a hard-headed Scotsman--he makes short work of the sentimentality which is invoked now-a-days against the natural law of marriage:--
