This quotation says on the whole the same thing which I have said in my proceeding letters. According to Socrates, all our thoughts and actions have a wider and more general purpose, which he calls the "good," so that we even do evil for the sake of good. A crime always aims at some particular good. Evil is misunderstood good. Applied to natural science, this means that it misunderstands the interrelation of all its fine discoveries. And this charge is true even to-day. Although the natural interrelations are more and more recognized from day to day, still the understanding of the absolute inter-connection continues to be overlooked, especially that of the intellect with material things, or of the ideal with the real. Natural science teaches after the manner of the gospel of John: Abraham begot Isaac, Isaac begot Jacob. But it forgets to teach that all these genitors were not genitors in the last analysis, but begotten by old Jehovah himself. The uncultivated condition of Grecian natural sciences may have been ground enough for Socrates to think little of it. We, on the other hand, have to-day good reasons for thinking highly of natural science, and for this very reason I take pains to illustrate by its prominent example in what respect the neglect of the universal world thought results in a narrow conception of the world. We may well rejoice more lastingly than Socrates when natural science teaches us how it happens that everything has its origin, life, and end, because the knowledge of natural science has been far more enriched by modern experiences than it was at the time of Anaxagoras. Nevertheless you must not stop learning furthermore from logic that all growing, coming into existence, living, and passing away is but a change of form. The causes of natural science are indeed not causes, but effects of the universe. They are reasonable effects of reason in so far as the latter is not an isolated part, but interconnected with the universe. To repeat: Our intellect is not ours, it does not belong to man, but it together with man belongs to the universe. Reason and the world, the true, the good, and the beautiful, together with Godhood which you shall not idolize but understand in the spirit and in the world, in truth and in reality, are all one thing, one being, and everywhere eternal and the _same_.
