the empty word-juggling of this loathsome philophaster. That in _practical_ philosophy also no wisdom is brought to light from mere abstract conceptions is the one thing to be learnt from the ethical dissertations of the theologian Schleiermacher, with the delivery of which he has wearied the Berlin Academy for a number of years, and which are shortly to appear in a collected form. In them only abstract conceptions, such as duty, virtue, highest good, moral law, &c., are taken as the starting-point, without further introduction than that they commonly occur in ethical systems, and are now treated as given realities. He then discusses these from all sides with great subtilty, but, on the other hand, never makes for the source of these conceptions, for the thing itself, the actual human life, to which alone they are related, from which they ought to be drawn, and with which morality has, properly speaking, to do. On this account these diatribes are just as unfruitful and useless as they are tedious, which is saying a great deal. At all times we find persons, like this theologian, who is too fond of philosophising, famous while they are alive, afterwards soon forgotten. My advice is rather to read those whose fate has been the opposite of this, for time is short and valuable. Now although, in accordance with all that has been said, wide, abstract conceptions, which can be realised in no perception, must never be the source of knowledge, the starting-point or the proper material of philosophy, yet sometimes particular results of philosophy are such as can only be thought in the abstract, and cannot be proved by any perception. Knowledge of this kind will certainly only be half knowledge; it will, as it were, only point out the place where what is to be known lies; but this remains concealed. Therefore we should only be satisfied with such conceptions in the most extreme case, and when we have reached the limit of the knowledge possible to our faculties. An example of this might perhaps be the conception of a being out of time; such as the proposition: the indestructibility of our true being by death is not a continued existence of it. With conceptions of this sort the firm ground which supports our whole knowledge, the perceptible, seems to waver. Therefore philosophy may certainly at times, and in case of necessity, extend to such knowledge, but it must never begin with it.
