and it is against foes belonging to other species that their weapons are directed. It is against lions and panthers that the gazelle fights for existence by its vigilance and speed, not against its own fellows; lions and panthers employ their cunning and strength against the gazelle and the buffalo, and not against other lions and panthers. Conflict among ourselves and against members of our own species was and is the privilege of the human race. But this sad privilege has sprung from a necessity of civilisation. In order to develop into what we have become we have been obliged to demand from nature more than she is in a position voluntarily to offer us; and for many thousands of years there has been no way of obtaining it but that of satisfying our higher needs by a system of mutual plunder and oppression. And in this way want became a stimulus to conflict in the human struggle for existence. Note, therefore, that the fighting of man against man, with material care as the sharpest spur to the conflict, was not and is not the simple transference to human society of a law everywhere prevalent in nature, but an exceptional distortion of this great natural law under the influence of a certain phase of human development. We suffered want not because nature compelled us to do so, but because we robbed each other; and we robbed each other because with civilisation there arose a disproportion between our requirements and our natural means of satisfying them. But now that civilisation has attained to control over the forces of nature, this disproportion is removed; in order to enjoy plenty and leisure we no longer need to exploit each other. Thus, to put an end to the conflict of man with man, and at the same time of material want, is not to depart from the natural form of the struggle for existence, but in reality to return to it. The struggle is not ended, but simply the unnatural form of it. In its endeavour to raise itself above the level of the merely animal nature, humanity was betrayed into a long-enduring strife with nature herself; and this strife was the source of all the unspeakable torture and suffering, crime and cruelty, the unbroken catalogue of which makes up the history of mankind from the first dawn of civilisation until now. But this dreadful strife is now ended by a most glorious victory; we have become what we have endeavoured for thousands of years to become, a race able to win from nature plenty and leisure for all its members; and by this very re-acquired harmony between our needs and the means of satisfying them have we brought ourselves again into unison with nature. We remain subject to nature's unalterable law of the struggle for existence; but henceforth we shall engage in this conflict in the same manner as all other creatures of nature--our struggle will be an external, not an internal one, not against our fellow-men nor prompted by the sting of material want.'
