There's another ancient text I could have mentioned: Galen's That the Best Physician is Also a Philosopher. It's essentially a call to arms for doctors to concentrate on the perfection of their clinical skills and to give up on ideas of attempts to get rich through their art. It shows all the ways in which he doesn't trust those doctors who use their talents for a gain other than the benefit of their patients. It is short and elegant.
