If we thus understand the nation, it follows that not only every man must bear the imprint of his nationality, but that also there is no true science, no man's science, which is not national. The ancients believed, in conformity with the teachings of the Greeks, that science soars outside of the human life, above the vicissitudes of mortals, beyond the current of history, which is troubled by the fatal conflicts of error, by falterings and doubts, and by the unsatisfied thirst for knowledge. Truth, lofty, pure, motionless, and unchangeable, was to them the fixed goal toward which the human mind moved, but completely severed from it and transcendent. This concept, after two thousand years of speculation, was to reveal itself as abstract and therefore fallacious,--abstract from the human mind, which at every given instance mirrors itself in such an image of truth, ever gazing upon an eternal ideal but always intent on reshaping it in a new and more adequate form. The modern world, at first with dim consciousness, and guided rather by a fortunate intuition than by a clear concept of its own real orientation, then with an ever clearer, ever more critical conviction, has elaborated a concept which is directly antithetical to the classical idea of a celestial truth removed from the turmoil of earthly things. It has accordingly and by many ways reached the conclusion that reality, lofty though it be, and truth itself, which nourishes the mind and alone gives validity to human thought, are in life itself, in the development of the mind, in the growth of the human personality, and that this personality, though ideally beyond our grasp, is yet in the concrete always historical and actual, and realises itself in its immanent value. It therefore creates its truth and its world. Modern philosophy and modern consciousness no longer point to values which, transcending history, determine its movement and its direction by external finalities: they show to man that the lofty aim which is his law is within himself; that it is in his ever unsatisfied personality as it unceasingly strains upward towards its own ideal. Science is no longer conceived to-day as the indifferent pure matter of the intellect. It is an interest which invests the entire person, extols it and with it moves onward in the eternal rhythm of an infinite development. Science is not for us the abstract contemplation of yore; it is self-consciousness that man acquires, and by means of which he actuates his own humanity. And therefore science is no longer an adornment or an equipment of the mind, considered as diverse to its content; it is culture, and the formation of this very mind. So that whenever science is as yet so abstract that it seems not to touch the person and fails to form it or transform it, it is an indication that it is not as yet true science.
