In passing through Paris, Edgeworth and Mr. Day went to see Rousseau, who took a good deal of notice of Edgeworth’s son; he judged him to be a boy of abilities, and he thought from his answers that ’history can be advantageously learned by children, if it be taught reasonably and not merely by rote.’  ‘But,’ said Rousseau, ’I remark in your son a propensity to party prejudice, which will be a great blemish in his character.’

’I asked how he could in so short a time form so decided an opinion.  He told me that, whenever my son saw a handsome horse, or a handsome carriage in the street, he always exclaimed, “That is an English horse or an English carriage!” And that, even down to a pair of shoe-buckles, everything that appeared to be good of its kind was always pronounced by him to be English. “his sort of party prejudice,” said Rousseau, “if suffered to become a ruling motive in his mind, will lead to a thousand evils; for not only will his own country, his own village or club, or even a knot of his private acquaintance, be the object of his exclusive admiration; but he will be governed by his companions, whatever they may be, and they will become the arbiters of destiny."’

It was while at Lyons that Edgeworth realised thaf Rousseau’s system of education was not altogether satisfactory.  He says:  ’I had begun his education upon the mistaken principles of Rousseau; and I had pursued them with as much steadiness, and, so far as they could be advantageous, with as much success as I could desire.  Whatever regarded the health, strength, and agility of my son had amply justified the system of my master; but I found myself entangled in difficulties with regard to my child’s mind and temper.  He was generous, brave, good-natured, and what is commonly called goodtempered; but he was scarcely to be controlled.  It was difficult to urge him to anything that did not suit his fancy, and more difficult to restrain him from what he wished to follow.  In short, he was self-willed, from a spirit of independence, which had been inculcated by his early education, and which he cherished the more from the inexperience of his own powers.

’I must here acknowledge, with deep regret, not only the error of a theory, which I had adopted at a very early age, when older and wiser persons than myself had been dazzled by the eloquence of Rousseau; but I must also reproach myself with not having, after my arrival in France, paid as much attention to my boy as I had done in England, or as much as was necessary to prevent the formation of those habits, which could never afterwards be eradicated.’

Edgeworth, finding that the tutor he had brought from England was not able to control his son, resolved to send young Richard to school at Lyons.  The Jesuits had lately been dismissed, but the Peres de L’Oratoire had taken charge of their Seminary, and to them Edgeworth resolved to intrust his son, having been first assured by the Superior that he would not attempt to convert the boy, and would forbid the under-masters to do so.  A certain Pere Jerome, however, desired to make the boy a good Catholic; and the Superior frankly told Edgeworth the circumstance, saying,’One day he took your boy between his knees, and began from the beginning of things to teach him what he ought to believe.  “My little man,” said he, “did you ever hear of God?”
