“The first impression of the writings of Mr. J. J. Rousseau received by a knowledgeable reader, who is reading for something more than vanity or to kill time, is that he is encountering a lucidity of mind, a noble impulse of genius and a sensitive soul of such a high level that perhaps never an author of whatever epoch or of whatever people has been able to possess in combination. The impression that immediately follows is bewilderment over the strange and contradictory opinions, which so oppose those which are in general circulation that one can easily come to the suspicion that the author, by virtue of his extraordinary talent, wishes to show off only the force of his bewitching wit and through the magic of rhetoric make himself something apart who through captivating novelties stands out among all rivals at wit.”

“A child who passes through many hands in turn, can never be well brought up. At every change he makes a secret comparison, which continually tends to lessen his respect for those who control him, and with it their authority over him. If once he thinks there are grown-up people with no more sense than children the authority of age is destroyed and his education is ruined.”

“There are, first of all, two kinds of authors: those who write for the subject's sake, and those who write for writing's sake. [...] The truth is that when an author begins to write for the sake of covering paper, he is cheating the reader; because he writes under the pretext that he has something to say.”

“Every reader, if he has a strong mind, reads himself into the book, and amalgamates his thoughts with those of the author.”

“A book can never be anything more than the impress of its author's thoughts; and the value of these will lie either in the matter about which he has thought, or in the form which his thoughts take, in other words, what it is that he has thought about it.”

“And when neither their property nor honour is touched, the majority of men live content, and he has only to contend with the ambition of a few, whom he can curb with ease in many ways. It makes him contemptible to be considered fickle, frivolous, effeminate, mean-spirited, irresolute, from all of which a prince should guard himself as from a rock; and he should endeavour to show in his actions greatness, courage, gravity, and fortitude; and in his private dealings with his subjects let him show that his judgments are irrevocable, and maintain himself in such reputation that no one can hope either to deceive him or to get round him. That prince is highly esteemed who conveys this impression of himself, and he who is highly esteemed is not easily conspired against; for, provided it is well known that he is an excellent man and revered by his people, he can only be attacked with difficulty.”
