Let us leave aside the query as to why we possess these two different ways of thinking, and turn back to the second proposition, namely, how comes it that we have two different ways of thinking? I have intimated above that history shows us that directed thinking was not always as developed as it is at present. In this age the most beautiful expression of directed thinking is science, and the technic fostered by it. Both things are indebted for their existence simply to an energetic education in directed thinking. At the time, however, when a few forerunners of the present culture, like the poet Petrarch, first began to appreciate Nature understandingly[30] there was already in existence an equivalent for our science, to wit, scholasticism.[31] This took its objects from the phantasies of the past, and it gave to the mind a dialectic training in directed thinking. The only success which beckoned the thinker was rhetorical victory in disputation, and not a visible transformation of reality. The subjects of thinking were often astonishingly phantastical; for example, questions were discussed, such as how many angels could have a place on the point of a needle? Whether Christ could have done his work of redemption equally well if he had come into the world as a pea? The possibility of such problems, to which belong the metaphysical problems in general, viz., to be able to know the unknowable, shows us of what peculiar kind that mind must have been which created such things which to us are the height of absurdity. Nietzsche had guessed, however, at the biological background of this phenomenon when he spoke of the “beautiful tension” of the Germanic mind which the Middle Ages created. Taken historically, scholasticism, in the spirit of which persons of towering intellectual powers, such as Thomas of Aquinas, Duns Scotus, Abélard, William of Occam and others, have labored, is the mother of the modern scientific attitude, and a later time will see clearly how and in what scholasticism still furnishes living undercurrents to the science of to-day. Its whole nature lies in dialectic gymnastics which have raised the symbol of speech, the word, to an almost absolute meaning, so that it finally attained to that substantiality which expiring antiquity could lend to its _logos_ only temporarily, through attributes of mystical valuation. The great work of scholasticism, however, appears to be the foundation of firmly knitted intellectual sublimation, the _conditio sine qua non_ of the modern scientific and technical spirit.
