ORIGIN AND MEANING.—Why does this thought come into my mind again and again, always in more and more vivid colours?—that, in former times, investigators, in the course of their search for the origin of things, always thought that they found something which would be of the highest importance for all kinds of action and judgment: yea, that they even invariably postulated that the salvation of mankind depended upon _insight into the origin of things_—whereas now, on the other hand, the more we examine into origins, the less do they concern our interests: on the contrary, all the valuations and interestedness which we have placed upon things begin to lose their meaning, the more we retrogress where knowledge is concerned and approach the things themselves. _The origin becomes of less significance in proportion as we acquire insight into it_; whilst things nearest to ourselves, around and within us, gradually begin to manifest their wealth of colours, beauties, enigmas, and diversity of meaning, of which earlier humanity never dreamed. In former ages thinkers used to move furiously about, like wild animals in cages, steadily glaring at the bars which hemmed them in, and at times springing up against them in a vain endeavour to break through them: and happy indeed was he who could look through a gap to the outer world and could fancy that he saw something of what lay beyond and afar off.
A TRAGIC TERMINATION TO KNOWLEDGE.—Of all the means of exaltation, human sacrifices have at times done most to elevate man. And perhaps the one powerful thought—the idea of _self-sacrificing humanity_—might be made to prevail over every other aspiration, and thus to prove the victor over even the most victorious. But to whom should the sacrifice be made? We may already swear that, if ever the constellation of such an idea appeared on the horizon, the knowledge of truth would remain the single but enormous object with which a sacrifice of such a nature would be commensurate—because no sacrifice is too great for it. In the meantime the problem has never been expounded as to how far humanity, considered as a whole, could take steps to encourage the advancement of knowledge; and even less as to what thirst for knowledge could impel humanity to the point of sacrificing itself with the light of an anticipated wisdom in its eyes. When, perhaps, with a view to the advancement of knowledge, we are able to enter into communication with the inhabitants of other stars, and when, during thousands of years, wisdom will have been carried from star to star, the enthusiasm of knowledge may rise to such a dizzy height!
