It is permissible to call this almost universal acceptance of social cooperation a natural phenomenon. In resorting to this mode of expression and asserting that conscious association is in conformity with human nature, one implies that man is characterized as man by reason, is thus enabled to become aware of the great principle of cosmic becoming and evolution, viz., differentiation and integration, and to make intentional use of this principle to improve his condition. But one must not consider cooperation among the individuals of a biological species a universal natural phenomenon. The means of sustenance are scarce for every species of living beings. Hence biological competition prevails among the members of all species, an irreconcilable conflict of vital “interests.” Only a part of those who come into existence can survive. Some perish because others of their own species have snatched away from them the means of sustenance. An implacable struggle for existence goes on among the members of each species precisely because they are of the same species and compete with other members of it for the same scarce opportunities of survival and reproduction. Man alone by dint of his reason substituted social cooperation for biological competition. What made social cooperation possible is, of course, a natural phenomenon, the higher productivity of labor accomplished under the principle of the division of labor and specialization of tasks. But it was necessary to discover this principle, to comprehend its bearing upon human affairs, and to employ it consciously as a means in the struggle for existence.
The fundamental facts about social cooperation have been misinterpreted by the school of social Darwinism as well as by many of its critics. The former maintained that war among men is an inevitable phenomenon and that all attempts to bring about lasting peace among nations are contrary to nature. The latter retorted that the struggle for existence is not among members of the same animal species but among the members of various species. As a rule tigers do not attack other tigers but, taking the line of least resistance, weaker animals. Hence, they concluded, war among men, who are specimens of the same species, is unnatural.2
Both schools misunderstood the Darwinian concept of the struggle for survival. It does not refer merely to combat and blows. It means metaphorically the tenacious impulse of beings to keep alive in spite of all factors detrimental to them. As the means of sustenance are scarce, biological competition prevails among all individuals—whether of the same or different species—which feed on the same stuff. It is immaterial whether or not tigers fight one another. What makes every specimen of an animal species a deadly foe of every other specimen is the mere fact of their life-and-death rivalry in their endeavors to snatch a sufficient amount of food. This inexorable rivalry is present also among animals gregariously roaming in droves and flocks, among ants of the same hill and bees of the same swarm, among the brood hatched by common parents and among the seeds ripened by the same plant. Only man has the power to escape to some extent from the rule of this law by intentional cooperation. So long as there is social cooperation and population has not increased beyond the optimum size, biological competition is suspended. It is therefore inappropriate to refer to animals and plants in dealing with the social problems of man.
Yet man’s almost universal acknowledgment of the principle of social cooperation did not result in agreement regarding all interhuman relations. While almost all men agree in looking upon social cooperation as the foremost means for realizing all human ends, whatever they may be, they disagree as to the extent to which peaceful social cooperation is a suitable means for attaining their ends and how far it should be resorted to.
Those whom we may call the harmonists base their argument on Ricardo’s law of association and on Malthus’ principle of population. They do not, as some of their critics believe, assume that all men are biologically equal. They take fully into account the fact that there are innate biological differences among various groups of men as well as among individuals belonging to the same group. Ricardo’s law has shown that cooperation under the principle of the division of labor is favorable to all participants. It is an advantage for every man to cooperate with other men, even if these others are in every respect—mental and bodily capacities and skills, diligence and moral worth—inferior. From Malthus’ principle one can deduce that there is, in any given state of the supply of capital goods and knowledge of how to make the best use of natural resources, an optimum size of population. So long as population has not increased beyond this size, the addition of newcomers improves rather than impairs the conditions of those already cooperating.
In the philosophy of the antiharmonists, the various schools of nationalism and racism, two different lines of reasoning must be distinguished. One is the doctrine of the irreconcilable antagonism prevailing among various groups, such as nations or races. As the antiharmonists see it, community of interests exists only within the group among its members. The interests of each group and of each of its members are implacably opposed to those of all other groups and of each of their members. So it is “natural” there should be perpetual war among various groups. This natural state of war of each group against every other group may sometimes be interrupted by periods of armistice, falsely labeled periods of peace. It may also happen that sometimes in warfare a group cooperates in alliances with other groups. Such alliances are temporary makeshifts of politics. They do not in the long run affect the inexorable natural conflict of interests. Having, in cooperation with some allied groups, defeated several of the hostile groups, the leading group in the coalition turns against its previous allies in order to annihilate them too and to establish its own world supremacy.
The second dogma of the nationalist and racist philosophies is considered by its supporters a logical conclusion derived from their first dogma. As they see it, human conditions involve forever irreconcilable conflicts, first among the various groups fighting one another, later, after the final victory of the master group, between the latter and the enslaved rest of mankind. Hence this supreme elite group must always be ready to fight, first to crush the rival groups, then to quell rebellions of the slaves. The state of perpetual preparedness for war enjoins upon it the necessity of organizing society after the pattern of an army. The army is not an instrument destined to serve a body politic; it is rather the very essence of social cooperation, to which all other social institutions are subservient. The individuals are not citizens of a commonwealth; they are soldiers of a fighting force and as such bound to obey unconditionally the orders issued by the supreme commander. They have no civil rights, merely military duties.
Thus even the fact that the immense majority of men look upon social cooperation as the foremost means to attain all desired ends does not provide a basis for a wide-reaching agreement concerning either ends or means.
3 A Remark on the Alleged Medieval Unanimity
In examining the doctrines of eternal absolute values we must also ask whether it is true or not that there was a period of history in which all peoples of the West were united in their acceptance of a uniform system of ethical norms.
Until the beginning of the fourth century the Christian creed was spread by voluntary conversions. There were also later voluntary conversions of individuals and of whole peoples. But from the days of Theodosius I on, the sword began to play a prominent role in the dissemination of Christianity. Pagans and heretics were compelled by force of arms to submit to the Christian teachings. For many centuries religious problems were decided by the outcome of battles and wars. Military campaigns determined the religious allegiance of nations. Christians of the East were forced to accept the creed of Mohammed, and pagans in Europe and America were forced to accept the Christian faith. Secular power was instrumental in the struggle between the Reformation and the Counter Reformation.
There was religious uniformity in Europe of the Middle
