Giorgio Agamben, Idea of Prose:
Study, in effect, is per se interminable. Those who are acquainted with long hours spent roaming among books, when every fragment, every codex, every initial encountered seems to open a new path, immediately left aside at the next encounter, or who have experienced the labyrinthine allusiveness of that “law of good neighbors” whereby Warburg arranged his library, know that not only can study have no rightful end, but does not even desire one.
Here the etymology of the word studium becomes clear. It goes back to a st- or sp- root indicating a crash, the shock of impact. Studying and stupefying are in this sense akin: those who study are in the situation of people who have received a shock and are stupefied by what has struck them, unable to grasp it and at the same time powerless to leave hold. The scholar, that is, is always “stupid.” But if on the one hand he is astonished and absorbed, if study is thus essentially a suffering and an undergoing, the messianic legacy it contains drives him, on the other hand, incessantly toward closure. This festina lente, this shuttling between bewilderment and lucidity, discovery and loss, between agent and patient, is the rhythm of study.
