The examination of the heart takes its start with Socrates, and all the contents of the heart are sifted. In their last and extremest struggles the ancients threw all contents out of the heart and let it no longer beat for anything; this was the deed of the Skeptics. The same purgation of the heart was now achieved in the Skeptical age, as the understanding had succeeded in establishing in the Sophistic age. The Sophistic culture has brought it to pass that one's understanding no longer _stands still_ before anything, and the Skeptical, that his heart is no longer _moved_ by anything. So long as man is entangled in the movements of the world and embarrassed by relations to the world,--and he is so till the end of antiquity, because his heart still has to struggle for independence from the worldly,--so long he is not yet spirit; for spirit is without body, and has no relations to the world and corporality; for it the world does not exist, nor natural bonds, but only the spiritual, and spiritual bonds. Therefore man must first become so completely unconcerned and reckless, so altogether without relations, as the Skeptical culture presents him,--so altogether indifferent to the world that even its falling in ruins would not move him,--before he could feel himself as worldless, _i. e._ as spirit. And this is the result of the gigantic work of the ancients: that man knows himself as a being without relations and without a world, as _spirit_. Only now, after all worldly care has left him, is he all in all to himself, is he only for himself, i. e. he is spirit for the spirit, or, in plainer language, he cares only for the spiritual. In the Christian wisdom of serpents and innocence of doves the two sides--understanding and heart--of the ancient liberation of mind are so completed that they appear young and new again, and neither the one nor the other lets itself be bluffed any longer by the worldly and natural. Thus the ancients mounted to _spirit_, and strove to become _spiritual_. But a man who wishes to be active as spirit is drawn to quite other tasks than he was able to set himself formerly: to tasks which really give something to do to the spirit and not to mere sense or acuteness,[10] which exerts itself only to become master of _things_. The spirit busies itself solely about the spiritual, and seeks out the "traces of mind" in everything; to the _believing_ spirit "everything comes from God," and interests him only to the extent that it reveals this origin; to the _philosophic_ spirit everything appears with the stamp of reason, and interests him only so far as he is able to discover in it reason, _i. e._ spiritual content.
