In this connection there is no problem which gives rise to greater complications and severer conflicts than that in regard to the preservation and raising of the standard of material existence. If, in general, we attribute incomparably more value to the material in life than was done formerly, so here also the problems of modern labour reach their climax. The organisation and concentration of labour have made by far their greatest progress in this matter; a gigantic accumulation of capital on the one side and of labour power on the other has intensified to the uttermost the opposition between man and man. In this conflict more than in any other the whole being of man comes into play; here, therefore, the most powerful passions flame up. No wonder that, if the thought of a fundamental re-organisation rises to the surface, it wins an influence amounting to fascination, arouses the hope of an essential advancement of the whole of human existence, and impels men to vigorous activity. Thus, then, this sphere, in which fact is regarded as principle, and in which the problem of the development of society is elevated to a position of importance above all others, and seeks to impress its stamp upon the whole of life, is first and foremost. From this point of view the organisation of society is the central problem of all culture, and a distinctive social culture, a social system of life, is evolved. But that which emerges at this point with especial power and clearness would not have been able to win men so quickly and influence them so strongly if it did not constitute a high-water mark of a wider movement, of a general tendency of the modern man to regard the social relation as being of the essence of life, and to shape life anew from this. Viewed historically, this tendency arose as a reaction against the practice of placing the individual in the foreground, a practice which since the beginning of the Modern Age had been resorted to in the most diverse departments of life. What was felt to be unconditionally right in opposition to the bondage of the Middle Ages has, in the course of time, shown a reverse side. Many painful experiences have led us to favour a movement in the direction of the whole again; and so it comes about that all hope of amelioration is able to be regarded as inevitably bound up with the complete victory of this movement. A distinctive social type of life can be formed and can strive for supremacy only if great problems arise within society and if its position in the whole of our life is capable of and in need of change. It will soon be seen that the case is so in respect of both these things; and also that two movements, one more general in kind, and another more precise but also more uncertain as to its goal, are connected.
