Probably also it has been the more important in affecting our actual degree of happiness; affecting it beneficently in the main. For, while some myths and stories have filled men with dread and horror, a very large majority have had the opposite effect; and while many mechanical inventions have contributed to our material ease and comfort, it is not clear that they have much increased our actual happiness. Men accommodate themselves easily to changes in their material surroundings; what is a luxury today will be a necessity tomorrow; and very many of the material inventions have tended to artificial and unhealthful modes of living, with consequent physical deterioration and its accompanying loss of happiness. As to influence on history, however, the influence of the material inventions has probably been the greater. Immaterial inventions might have been made in enormous numbers without of themselves affecting history greatly; but the material inventions have brought about most of the events that history describes; and without one material invention, that of writing, history could not exist at all. History is rather a narrative of men's deeds than of their thoughts; and their deeds have been directed largely by the implements which they had to do deeds with. We must realize, of course, that the Greeks were much indebted to the Ægeans; for discoveries about the shores and islands of the Ægean Sea show that long before the advent of the Greeks they used tools and weapons of rough and then of polished stone, and later of copper and tin and bronze; that they lived on farms and in villages and cities, and were governed by monarchs who dwelt in palaces adorned with paintings and fine carvings, and filled with court gentlemen and ladies who wore jewelry and fine clothing. Exquisite pottery was used, decorated with taste and skill; ivory was carved and gems were engraved, and articles were made of silver and bronze and gold. As early as the sixth century B. C., the Greeks made things more beautiful than had ever been made before. One almost feels like saying that the Greeks invented beauty. Such a declaration would be absurd of course: but it seems to be a fact that the Greeks had a conception of beauty that was wholly original with them, and that was not only finer than that which any other people had ever had before, but finer than any other people have had since. And not only did they have the conception, they had the ability to embody the conception in material forms that possessed a beauty higher than had ever been produced before, and higher (at least on the average) than have ever been produced in any other country since.
