“This question of grades being coercive, and of politics being inherent in teaching, applies not only to writing, but to all fields. Mathematics, science, economics, history, religion, are all just as deeply and necessarily political. To believe they’re not—to believe, for example, that science (or mathematics, economics, history, religion, and so forth: choose your poison) describes the world as it is, rather than acting as a filter that removes all information that does not fit the model and colors the information that remains—is in itself to take a position, one that is all the more powerful and dangerous because it is invisible to the one who holds it.”
