In psychological reflection the greatest difficulty is this: that inner and outer must always be viewed in parallel lines, or, rather, interwoven. It is a continual systole and diastole, an inspiration and an expiration of the living soul. If this cannot be put into words, it should be carefully marked and noted.
My relations with Schiller rested on the decided tendency of both of us towards a single aim, and our common activity rested on the diversity of the means by which we endeavoured to attain that aim.
Once when a slight difference was mentioned between us, of which I was reminded by a passage in a letter of his, I made the following reflections: There is a great difference between a poet seeking the particular for the universal, and seeing the universal in the particular. The one gives rise to Allegory, where the particular serves only as instance or example of the general; but the other is the true nature of Poetry, namely, the expression of the particular without any thought of, or reference to, the general. If a man grasps the particular vividly, he also grasps the general, without being aware of it at the time; or he may make the discovery long afterwards.
There may be eclectic philosophers, but not an eclectic philosophy.
But every one is an eclectic who, out of the things that surround and take place about him, appropriates what is suited to his nature; and this is what is meant by culture and progress, in matters of theory or practice.
