In cursorily summarising these pages, we find that wherever and whenever beauty as the _ideal_, truth as the _real_, or goodness as the _ethical_ element in humanity, has been one-sidedly cultivated, works of art have not succeeded, for the harmony and union of these three can alone be the aim of humanity. This harmonious union it is difficult to attain, but we must endeavour to become historically conscious of the continuous striving of humanity to bring it about. We find two forces constantly at work in humanity--the one static (morals), the other dynamic (intellect)--bent upon leading us to culture, progress, truth, goodness, and beauty. In the fifth and at the beginning of the fourth century B.C., for once in our development, and then only for a short period, humanity undoubtedly succeeded in attaining a perfect balance of its moral, intellectual, and esthetical faculties. We may well call that period the golden age of mankind in art. We still live on the mere interest of that immense capital which was left by the Greeks as an imperishable legacy to humanity. Whatever the Greeks touched at that period they transformed into pearls of beauty, gold of truth, and jewels of goodness. They mounted the winged steed of imagination, and were taken up to the bright heaven of pure idealisation, where they saw boundless beauty in forms, and acquired an immortal striving after truth and the eternal laws of goodness, based on the very organisation of our complicated double nature. This dream of reality was short but vivid. Humanity lives still in an ineffaceable longing and a burning desire to regain that period. Like diamonds dropped in unknown ages in small crystallisations into the sand of rivers, the works of Greece appear in the stream of time, serving as a fundamental basis of beauty, truth, and goodness. The well-balanced harmony was unfortunately soon disturbed.
