Hunched backs

Almost always the books of scholars are somehow oppressive, oppressed: the "specialist" emerges somewhere—his zeal, his seriousness, his fury, his overestimation of the nook in which he sits and spins, his hunched back; every specialist has his hunched back. Every scholarly book also mirrors a soul that has become crooked; every craft makes crooked.…Nothing can be done about that. Let nobody suppose that one could possibly avoid such crippling by some artifice of education. On this earth one pays dearly for every kind of mastery.…For having a specialty one pays by also being the victim of this specialty. But you would have it otherwise—cheaper and fairer and above all more comfortable—isn't that right, my dear contemporaries. Well then, but in that case you also immediately get something else: instead of the craftsman and master, the "man of letters," the dexterous, "polydexterous" man of letters who, to be sure, lacks the hunched back—not counting the posture he assumes before you, being the salesman of the spirit and the "carrier" of culture—the man of letters who really is nothing but "represents" almost everything, playing and "substituting" for the expert, and taking it upon himself in all modesty to get himself paid, honored, and celebrated in place of the expert. 

No, my scholarly friends, I bless you even for your hunched back. And for despising, as I do, the "men of letters" and culture parasites. And for not knowing how to make a business of the spirit. And for having opinions that cannot be translated into financial values. And for not representing anything that you are not. And because your sole aim is to become masters of your craft, with reverence for every kind of mastery and competence, and with uncompromising opposition to everything that is semblance, half-genuine, dressed up, virtuosolike, demagogical, or histrionic in litteris et artibus—to everything that cannot prove to you its unconditional probity in discipline and prior training, [The Gay Science, sec. 366] Cited here.
