“Probably there is no department of science, no form o humanity, in which greater advances have been made of late years, than in the medical and moral management of the insane. When we contrast the spacious and airy apartments of the insane. When we contrast the spacious and airy apartments and the grounds of our asylums, with the dark, and narrow, and dirty cells, in which, twenty years ago, the best accommodated of these poor creatures were immured - their neat and confortable dress, with their former rags and nakedness - their wholesome food, with their former rags and nakedness - their wholesome food, their former rations - and abovel all, the kindness and affection which is shown to them noew, with their ulter neglect in the days when they were executed from the privileges and society of men, we find ourselves shuddering at the thought of what we have seen, and lost in admiration of what we now see.
Wherever the Christian religion exists, we find the same rapid advances making towards the accomplishment of the great purposes of humanity. It seems as if the miracles of our Saviour were meant as protoypes of what his religion was to accomplish. It is by the influence of this religion of the march of science and philosophical discovery, that, by all Christian nations, the winds and the waves have been rebuked - that man is enabled to ride out the storm upon the ocean, as if it were hushed, and, like Peter of old, to walk upon the sea as on dry land.”

The Future of Civilization (1938)
Context: We see the world as it is now, after these defeats of the League, and we can compare it with what it was six or seven years ago. The comparison is certainly depressing; the contrast is terrible. And we have not yet reached a time when we can estimate the full material losses and human suffering which have been the direct result of the ambitions of one set of powers and the weakness of the others. Nor is there any purpose in attempting to do so. Let us, rather, examine where we now stand and what steps we ought to take in order to strengthen the international system and thrust back again the forces of reaction.
In the first place, let us admit that the first ten years of the League were in a sense unnatural. The horror of war to which I have already alluded was necessarily far more vivid than it can be expected long to remain. That tremendous argument for peace, the horror of war, was a diminishing asset. Most of us, at that time, were, I think, quite well aware that unless we could get the international system into solidly effective working order in the first ten years, we were likely to have great difficulties in the succeeding period, and so it has proved.
