Progress is not an illusion, it happens, but it is slow and invariably disappointing. There is always a new tyrant waiting to take over from the old—generally not quite so bad, but still a tyrant. Consequently two viewpoints are always tenable. The one, how can you improve human nature until you have changed the system? The other, what is the use of changing the system before you have improved human nature? They appeal to different individuals, and they probably show a tendency to alternate in point of time. The moralist and the revolutionary are constantly undermining one another. Marx exploded a hundred tons of dynamite beneath the moralist position, and we are still living in the echo of that tremendous crash. But already, somewhere or other, the sappers are at work and fresh dynamite is being tamped in place to blow Marx at the moon. Then Marx, or somebody like him, will come back with yet more dynamite, and so the process continues, to an end we cannot yet foresee. The central problem—how to prevent power from being abused—remains unsolved. Dickens, who had not the vision to see that private property is an obstructive nuisance, had the vision to see that. ‘If men would behave decently the world would be decent’ is not such a platitude as it sounds.
