FTP, name this 1762 treatise on education by Jean-Jacques Rousseau.
Its author wrote it at the request of his friend Madame de Chenonceaux, referred to in the preface as "a good mother who knows how to think," and conceived it as a memoir of a few pages instead of the rambling 1, 749-paragraph treatise that it became.  Its sequel joins the title character to Sophie, who is introduced as a marital prospect in Book Five of this work.  The author alludes to previous works on the same subject by Locke and Plato, but insists that the first and most important book the title character reads will be Robinson Crusoe and that the title character should get his lessons from nature and not from man.
