An essay on this subject quotes a Scythian philosopher to open a section on the value of cold, and endorses wearing shoes thin enough to let (-5[1])in water. That essay on this subject, which originated as a series of letters to Edward Clarke, popularized the English translation “a sound mind in a sound body” (15[1])for a phrase of Juvenal’s. Another treatise on this subject attacks La Fontaine’s “The Crow and the Fox” and contains an oft-excerpted passage claiming that the “duties of (*) religion are independent of the institutions of men.” A treatise that included the scandalous “Creed of the Savoyard Vicar” discusses this subject, about which John Locke wrote “Some Thoughts.” (-5[1])For 10 points, Jean-Jacques Rousseau expounded his theories (10[1])of what practice in his novelistic treatise Emile?
