But the word Disease is applicable to our social as well as to our physical condition. For as in the body disease arises from the loss of the physical unity which constitutes Health, and so takes the form of warfare or discord between the various parts, or of the abnormal development of individual organs, or the consumption of the system by predatory germs and growths; so in our modern life we find the unity gone which constitutes true society, and in its place warfare of classes and individuals, abnormal development of some to the detriment of others, and consumption of the organism by masses of social parasites. If the word disease is applicable anywhere, I should say it is--both in its direct and its derived sense--to the civilised societies of to-day. Again, mentally, is not our condition most unsatisfactory? I am not alluding to the number and importance of the lunatic asylums which cover our land, nor to the fact that maladies of the brain and nervous system are now so common; but to the strange sense of mental unrest which marks our populations, and which amply justifies Ruskin's cutting epigram: that our two objects in life are, "Whatever we have--to get more; and wherever we are--to go somewhere else." This sense of unrest, of disease, penetrates down even into the deepest regions of man's being--into his moral nature--disclosing itself there, as it has done in all nations notably at the time of their full civilisation, as the sense of Sin.[1] All down the Christian centuries we find this strange sense of inward strife and discord developed, in marked contrast to the naive insouciance of the pagan and primitive world; and, what is strangest, we even find people glorying in this consciousness--which, while it may be the harbinger of better things to come, is and can be in itself only the evidence of loss of unity, and therefore of ill-health, in the very centre of human life.
