How many Forces must now be united in a Thinker.—To rise superior to considerations of the senses, to raise one's self to abstract contemplations: this is what was formerly regarded as elevation; but now it is not practicable for us to share the same feelings. Luxuriating in the [pg 050] most shadowy images of words and things; playing with those invisible, inaudible, imperceptible beings, was considered as existence in another and higher world, a world that sprang from the deep contempt felt for the world which was perceptible to the senses, this seductive and wicked world of ours. “These abstracta no longer mislead us, but they may lead us”—with such words men soared aloft. It was not the substance of these intellectual sports, but the sports themselves, which was looked upon as “the higher thing” in the primeval ages of science. Hence we have Plato's admiration for dialectics, and his enthusiastic belief in the necessary relationship of dialectics to the good man who has risen superior to the considerations of his senses. It was not only knowledge that was discovered little by little, but also the different means of acquiring it, the conditions and operations which precede knowledge in man. And it always seemed as if the newly-discovered operation or the newly-experienced condition were not a means of acquiring knowledge, but was even the substance, goal, and sum-total of everything that was worth knowing. What does the thinker require?—imagination, inspiration, abstraction, spirituality, invention, presentiment, induction, dialectics, deduction, criticism, ability to collect materials, an impersonal mode of thinking, contemplation, comprehensiveness, and lastly, but not least, justice, and love for everything that exists—but each one of these means was at one time considered, in the history of the vita contemplativa, as a goal and final purpose, and they all secured for [pg 051] their inventors that perfect happiness which fills the human soul when its final purpose dawns upon it.
