“The social use of intellectual life lies in its cultivation of broader and richer ways of being human, in shaping our aspirations and our hopes for ourselves. It is obvious and widely noticed that literature provides a broadening of our perspective: we sympathize in our imaginations with human beings different from us—people of different races, genders, religions, times, and places. But the same is true of mathematics and science. It is surely part of what it means to be a human being to think mathematically and scientifically; by studying these subjects, especially through the thinkers of the past, we see from the inside magnificent and strange human possibilities and modes of comprehension.”
