“...to you, differences are quite unimportant; to me, they are what matters most. I am a scholar by nature; science is my vocation. And science is, to quote your words, nothing but the 'determination to establish differences.' Its essence couldn't be defined more accurately. For us, the men of science, nothing is as important as the establishment of differences; science is the art of differentiation. Discovering in every man that which distinguishes him from others is to know him.”
