One cannot deny that in former times man's life had been one of toil and hardship. It is correct to say, therefore, that modern civilization and the progress of science have greatly improved man's life and have brought comfort and ease in their trail.
It is a simple matter to see the obvious, to do the expected. The tendency of the individual life is to be static rather than dynamic, and this tendency is made into a propulsion by civilization, where the obvious only is seen, and the unexpected rarely happens. When the unexpected does happen, however, and when it is of sufficiently grave import, the unfit perish. They do not see what is not obvious, are unable to do the unexpected, are incapable of adjusting their well-grooved lives to other and strange grooves. In short, when they come to the end of their own groove, they die.
When people talk as if the Crusades were nothing more than an aggressive raid against Islam, they seem to forget in the strangest way that Islam itself was only an aggressive raid against the old and ordered civilization in these parts. I do not say it in mere hostility to the religion of Mahomet; I am fully conscious of many values and virtues in it; but certainly it was Islam that was the invasion and Christendom that was the thing invaded.
The greatest problem for the human species, the solution of which nature compels him to seek, is that of attaining a civil society which can administer justice universally.
If you will notice, there is seldom a telegram in a paper which fails to show up one or more members & beneficiaries of our Civilization as promenading with his shirt-tail up & the rest of his regalia in the wash.
