In everything that which distinguishes the individual is thrust into the background to make way for that which is common; work has in the first place to concern itself with that which is common to all. In that here science makes man the chief study of man, it considers him especially as a social being and finds its chief theme in the knowledge of social conditions. Similarly, the chief subject of art is not, as was formerly the case, the doings and experience of individuals, but the forceful representation of these social conditions. The raising of the general level becomes the chief care of all practical activity, as also of education. According to this scheme the individual is of consequence and of worth only through those elements of the common life which he brings to expression, and through the way in which he reacts upon that life. The industry of universal history is understood, therefore, not from that which relates primarily to individuals, but from that relating to the movements and destinies of society. Such an estimate of the whole involves a conviction which seldom finds expression, but which silently exerts its influence everywhere: the belief in a summation of reason by the organisation of individuals into a whole. Only a belief of this kind is able to establish the supremacy of the mass over against the individuals, also in spiritual things; only such a belief is able to justify the hope of a victory of the good in the sphere of humanity. The net result of all these ideas and tendencies is a co-ordinated system of thought, a distinctive type of life. In this system man is first and foremost a member of society; he originates in it; he remains in it; and his activity carries implications far beyond his own life. Not community of labour only joins him with his fellows, but also the general tone of thought and feeling. This type of life is not one without sacrifice; for it has to give up many things which in earlier times seemed a secure possession and were a source of joy. Yet these things were only illusions which vanished, and mankind seems to find a compensation, more than equivalent for all that has been lost, in that it is more closely united and through this wins new powers; and henceforth out of its own capacity can venture to take up the struggle against every irrationality of existence, and to advance its own well-being without constraint. A life is therefore evolved, conscious of its limits, but at the same time active and courageous.
