Medicine
I firmly believe that if the whole materia medica could be sunk to the bottom of the sea, it would be all the better for mankind and all the worse for the fishes.
Physicians, of all men, are most happy; whatever good success soever they have, the world proclaimeth; and what faults they commit, the earth covereth.
The disease and its medicine are like two factions in a besieged town; they tear one another to pieces, but both unite against their common enemy, nature.
But nothing is more estimable than a physician who, having studied nature from his youth, knows the properties of the human body, the diseases which assail it, the remedies which will benefit it, exercises his art with caution, and pays equal attention to the rich and the poor.
