Error of philosophers: The philosopher believes that the value of his philosophy lies in the whole, in the building. But posterity discovers it in the bricks that he used and which others will often make use of again for better building; in the fact, that is to say, that the building can be destroyed and nevertheless possess value as material.
— Nietzsche, Human, All Too Human (1878)
