Man is not a 'fixed and limited animal whose nature is absolutely constant'. He changed drastically when he developed 'divided consciousness' to cope with complexities of civilisation, and has been changing steadily ever since. His greatest problem, the problem that has caused most of his agonies and miseries, has been his attempt to compensate for the narrowing of cinsciousness and the entrapment in the left-brain ego. His favorite method of compensation has been to seek out excitement. He feels most free in moments of conquest; so for the past three thousand years or so, most of the greatest man have led armies into their neighbours' territority, and turned order into chaos. This has plainly been a retrogressive step; the evolutionary urge has been defeating its own purpose.
