They no longer make geniuses like that

"Poincaré became a prolific essayist in his thirties. He seemed in a hurry and died prematurely, at fifty-eight ; he was in such a rush that he did not bother correcting typos and grammatical errors in his text , even after spotting them, since he found doing so a gross misuse of his time. They no longer make geniuses like that—or they no longer let them write in their own way."
