"Its name [alchemy] will no doubt prevent its being acceptable to many; but why should wise people hate without cause that which some other wantonly misuse? Why hate blue because some clumsy painter uses it? Which would Caesar order to be crucified, the thief or the thing he had stolen? No science can be deservedly held in contempt by one who knows noting about it. Because you are ignorant of alchemy, you are ignorant of the mysteries of nature."
