modern empiricism and technic, and which occurs for absolutely the first time in the history of the world. Inquisitive minds have often tormented themselves with the question why the undoubtedly extraordinary knowledge of mathematics and principles and material facts united with the unexampled art of the human hand in antiquity never arrived at the point of developing those known technical statements of fact, for instance, the principles of simple machines, beyond the realm of the amusing and curious to a real technic in the modern sense. There is necessarily only one answer to this; the ancients almost entirely, with the exception of a few extraordinary minds, lacked the capacity to allow their interest to follow the transformations of inanimate matter to the extent necessary for them to be able to reproduce the process of nature, creatively and through their own art, by means of which alone they could have succeeded in putting themselves in possession of the force of nature. That which they lacked was training in directed thinking, or, to express it psychoanalytically, the ancients did not succeed in tearing loose the libido which might be sublimated, from the other natural relations, and did not turn voluntarily to anthropomorphism.

It is, therefore, to be assumed that the directed thinking of our time is a more or less modern acquisition, which was lacking in earlier times.
But with that we come to a further question, viz., what happens if we do not think directedly? Then our thinking
