"Let mankind
Fear the gods!
They hold the power
In everlasting hands:
And they can use it
As seems good to them."
Such considerations, however, are really foreign to our subject. Some explanation as to the relation between the character and the knowledge in which all its motives lie, will now be more to the point.
The motives which determine the manifestation of the character or conduct influence it through the medium of knowledge. But knowledge is changeable, and often vacillates between truth and error, yet, as a rule, is rectified more and more in the course of life, though certainly in very different degrees. Therefore the conduct of a man may be observably altered without justifying us in concluding that his character has been changed. What the man really and in general wills, the striving of his inmost nature, and the end he pursues in accordance with it, this we can never change by influence upon him from without by instruction, otherwise we could transform him. Seneca says admirably, velle non discitur; whereby he preferred truth to his Stoic philosophers, who taught διδακτην ειναι την αρετην (doceri posse virtutem). From without the will can only be affected by motives. But [pg 380] these can never change the will itself; for they have power over it only under the presupposition that it is precisely such as it is. All that they can do is thus to alter the direction of its effort, i. e., bring it about that it shall seek in another way than it has hitherto done that which it invariably seeks. Therefore instruction, improved knowledge, in other words, influence from without, may indeed teach the will that it erred in the means it employed, and can therefore bring it about that the end after which it strives once for all according to its inner nature shall be pursued on an entirely different path and in an entirely different object from what has hitherto been the case. But it can never bring about that the will shall will something actually different from what it has hitherto willed; this remains unchangeable, for the will is simply this willing itself, which would have to be abolished. The former, however, the possible modification of knowledge, and through knowledge of conduct, extends so far that the will seeks to attain its unalterable end, for example, Mohammed's paradise, at one time in the real world, at another time in a world of imagination, adapting the means to each, and thus in the first case applying prudence, might, and fraud, and in the second case, abstinence, justice, alms, and pilgrimages to Mecca. But its effort itself has not therefore changed, still less the will itself. Thus, although its action certainly shows itself very different at different times, its willing has yet remained precisely the same. Velle non discitur.
