Question: What book written by Jean-Jacques Rousseau became a new national system of education during the French Revolution and inspired Thomas Day to educate two girls?
Context: Essay on the Origin of Languages (French: "Essai sur l'origine des langues" ) is an essay by Jean-Jacques Rousseau published posthumously in 1781.  Rousseau had meant to publish the essay in a short volume which was also to include essays "On Theatrical Imitation" and "The Levite of Ephraim."  In the preface to this would-be volume, Rousseau wrote that the "Essay" was originally meant to be included in the "Discourse on Inequality", but was omitted because it "was too long and out of place".  The essay was mentioned in Rousseau's 1762 book, "Emile". Practical Education is an educational treatise written by Maria Edgeworth and her father Richard Lovell Edgeworth.  Published in 1798, it is a comprehensive theory of education that combines the ideas of philosophers John Locke and Jean-Jacques Rousseau as well as of educational writers such as Thomas Day, William Godwin, Joseph Priestley, and Catharine Macaulay.  The Edgeworths' theory of education was based on the premise that a child's early experiences are formative and that the associations they form early in life are long-lasting.  They also encourage hands-on learning and include suggestions of "experiments" that children can perform and learn fun.  Following Locke's emphasis on the importance of concrete language over abstract, the Edgeworth's argued that words should clearly indicate "distinct ideas".  This contributed to what Romanticist Alan Richardson calls "their controversial positions", including their resistance to reading fairy tales to children or discussing religion with them. Emile, or On Education or Émile, or Treatise on Education (French: "Émile, ou De l’éducation" ) is a treatise on the nature of education and on the nature of man written by Jean-Jacques Rousseau, who considered it to be the "best and most important" of all his writings.  Due to a section of the book entitled "Profession of Faith of the Savoyard Vicar", "Emile" was banned in Paris and Geneva and was publicly burned in 1762, the year of its first publication.  During the French Revolution, "Emile" served as the inspiration for what became a new national system of education. Rousseau, Judge of Jean-Jacques (French: "Rousseau juge de Jean-Jacques") is a book written by Jean-Jacques Rousseau.  Rousseau's objective in writing this book was to respond to what he believed were slanderous and defamatory attacks on his reputation by his enemies.  He began writing it in 1772, and completed it in 1776.  The book is in the form of three dialogues between two characters, a "Frenchman" and "Rousseau", who argue about the merits and demerits of a third character--an author called "Jean-Jacques".  It has been described as Rousseau's most unreadable work; in the book's foreword, he concedes that the book might be repetitious and disorderly, but begs the reader's indulgence on the ground that he needs to defend his reputation from slander while he is still alive. Sabrina Bicknell (1757 – 8 September 1843), better known as Sabrina Sidney, was a British foundling girl taken in when she was 12 by author Thomas Day, who wanted to mould her into his perfect wife.  Day had been struggling to find a wife who would share his ideology and had been rejected by several women.  Inspired by Jean-Jacques Rousseau's book "Emile, or On Education", he decided to educate two girls without any frivolities, using his own concepts. Antoine Joseph Barruel-Beauvert (1756–1817) was a French military officer and journalist.  He was born Comte de Barruel-Beauvert, at the castle of Beauvert, in Languedoc, but was impoverished by the Revolution.  He took part in some events of the French Revolution.  He was also the first biographer of Jean-Jacques Rousseau. Rousseau Institute (also known as Jean-Jacques Rousseau Institute or Academy of Geneva; "French: "Académie De Genève" " or "Institut Jean-Jacques Rousseau") is a private school in Geneva, Switzerland.  In 1912, Édouard Claparède (1873–1940) created an institute to turn educational theory into a science.  This new institution was given the name of Jean-Jacques Rousseau, to whom Claparède attributed the "Copernican reversal" of putting the child, rather than the teacher, at the centre of the educational process (cf. Thomas Kuhn's notion of paradigm shift). Reveries of the Solitary Walker (French: "Les Rêveries du promeneur solitaire") is an unfinished book by Genevan philosopher Jean-Jacques Rousseau, written between 1776 and 1778.  It was the last of a number of works composed toward the end of his life which were deeply autobiographical in nature.  Previous elements in this group included "The Confessions" and "".  The book is divided into ten chapters called "Walks".  The Eighth and Ninth Walks were completed, but not revised by Rousseau, and the Tenth Walk was incomplete at Rousseau's death.  The first publication was in 1782. The Confessions is an autobiographical book by Jean-Jacques Rousseau.  In modern times, it is often published with the title The Confessions of Jean-Jacques Rousseau in order to distinguish it from Saint Augustine's "Confessions".  Covering the first fifty-three years of Rousseau's life, up to 1765, it was completed in 1769, but not published until 1782, four years after Rousseau's death, even though Rousseau did read excerpts of his manuscript publicly at various salons and other meeting places. Amour-propre (French, "self-love") is a concept in the philosophy of Jean-Jacques Rousseau that esteem depends upon the opinion of others.  Rousseau contrasts it with "amour de soi", which also means "self-love", but which does not involve seeing oneself as others see one.  According to Rousseau, "amour de soi" is more primitive and is compatible with wholeness and happiness, while "amour-propre" is an unnatural form of self-love that arose only with the appearance of society and individuals' consequent ability to compare themselves with one another.  Rousseau thought that "amour-propre" was subject to corruption, thereby causing vice and misery.
