Thus lives the wise old man, and in living thus he falls almost imperceptibly into such a deplorable proximity to priestly and poetic extravagances that it is difficult to recollect all his wise and severe period of youth, the former rigid morality of his mind, and his truly virile dread of fancies and misplaced enthusiasm. When he was formerly in the habit of comparing himself with the older thinkers, he did so merely that he might measure his weakness against their strength, and that he might become colder and more audacious towards himself; but now he only makes this comparison to intoxicate himself with his own delusions. Formerly he looked forward with confidence to future thinkers, and he even took a delight in imagining himself to be cast into the shade by their brighter light. Now, however, he is mortified to think that he cannot be the last: he endeavours to discover some way of imposing upon mankind, together with the inheritance which he is leaving to them, a restriction of sovereign thinking. He fears and reviles the pride and the love of freedom of individual minds: after him no one must allow his intellect to govern with absolute unrestriction: he himself wishes to remain for ever the bulwark on which the waves of ideas may break—these are his secret wishes, and perhaps, indeed, they are not always secret. The hard fact upon which such wishes are based, however, is that he himself has come to a halt before his teaching, and has set up his boundary stone, his “thus far and no farther.” In canonising himself he has drawn up his own death warrant: from now on his mind cannot develop further. His race is run; the hour-hand stops. Whenever a great thinker tries to make himself a lasting institution for posterity, we may readily suppose that he has passed the climax of his powers, and is very tired, very near the setting of his sun. 543. WE MUST NOT MAKE PASSION AN ARGUMENT FOR TRUTH.—Oh, you kind-hearted and even noble enthusiasts, I know you! You wish to seem right in our eyes as well as in your own, but especially in your own!—and an irritable and subtle evil conscience so often spurs you on against your very enthusiasm! How ingenious you then become in deceiving your conscience, and lulling it to sleep! How you hate honest, simple, and clean souls; how you avoid their innocent glances! That better knowledge whose representatives they are, and whose voice you hear only too distinctly within yourselves when it questions your belief,—how you try to cast suspicion upon it as a bad habit, as a disease of the age, as the neglect and infection of your own intellectual health! It drives you on to hate even criticism, science, reason! You must falsify history to make it testify in your favour; you must deny virtues in case they should obscure those of your own idols and ideals.
