“Such as we know is false, yet dread in sooth, Because the worst is ever nearest truth.”
_Love_ and _hate_ falsify our judgment entirely. In our enemies we see nothing but faults—in our loved ones nothing but excellences, and even their faults appear to us amiable. Our _interest_, of whatever kind it may be, exercises a like secret power over our judgment; what is in conformity with it at once seems to us fair, just, and reasonable; what runs contrary to it presents itself to us, in perfect seriousness, as unjust and outrageous, or injudicious and absurd. Hence so many prejudices of position, profession, nationality, sect, and religion. A conceived hypothesis gives us lynx-eyes for all that confirms it, and makes us blind to all that contradicts it. What is opposed to our party, our plan, our wish, our hope, we often cannot comprehend and grasp at all, while it is clear to every one else; but what is favourable to these, on the other hand, strikes our eye from afar. What the heart opposes the head will not admit. We firmly retain many errors all through life, and take care never to examine their ground, merely from a fear, of which we ourselves are conscious, that we might make the discovery that we had so long believed and so often asserted what is false. Thus then is the intellect daily befooled and corrupted by the impositions of inclination. This has been very beautifully expressed by Bacon of Verulam in the words: _Intellectus_ LUMINIS SICCI _non est; sed recipit infusionem a voluntate et affectibus: id quod generat ad quod vult scientias: quod enim mavult homo, id potius credit. Innumeris modis, iisque interdum imperceptibilibus, affectus intellectum imbuit et inficit_ (_Org. Nov._, i. 14). Clearly it is also this that opposes all new fundamental opinions in the sciences and all refutations of sanctioned errors, for one will not easily see the truth of that which convicts one of incredible want of thought. It is explicable, on this ground alone, that the truths of Goethe’s doctrine of colours, which are so clear and simple, are still denied by the physicists; and thus Goethe himself has had to learn what a much harder position one has if one promises men instruction than if one promises them amusement. Hence it is much more fortunate to be born a poet than a philosopher. But the more obstinately an error was held by the other side, the more shameful does the conviction afterwards become. In the case of an overthrown system, as in the case of a conquered army, the most prudent is he who first runs away from it.
