I could fill volumes with descriptions of temples and palaces, paintings, sculptures, tapestry, porcelain, etc., etc., etc.—if I could have time. But I could not do this without neglecting my duty. The science of government it is my duty to study, more than all other sciences: the art of legislation and administration and negotiation, ought to take place, indeed to exclude in a manner all other arts. I must study politics and war that my sons may have liberty to study mathematics and philosophy. My sons ought to study mathematics and philosophy, geography, natural history, naval architecture, navigation, commerce, and agriculture, in order to give their children a right to study painting, poetry, music, architecture, statuary, tapestry, and porcelain.
