Twilight

The philosopher and age - It is not wise to let the evening judge the day: for it means all too often that weariness sits in judgment on strength, success and good will. And great caution is likewise in order with regard to age and its judgment of life, especially as, like evening, age loves to dress itself in a new and enticing morality and knows how to put the day to shame through twilight and solemn or passionate silence. The reverence we accord the aged man, especially when he is an aged thinker and sage, easily blinds us to the aging of his mind, and it is always necessary to draw forth the signs of such an aging and weariness out of their hiding-place draw forth, that is to say, the physiological phenomenon behind the moral predispositions and prejudices so as not to become the fools of reverence and injurers of knowledge . . . . Whenever a great thinker wants to make of himself a binding institution for future mankind, one may be certain that he is past the peak of his powers and is very weary, very close to the setting of his sun. - Nietzsche (Daybreak #542)
