I shall choose the time, place, and surroundings most favourable to the impression I wish to make; I shall… — Jean Jacques Rousseau

I shall choose the time, place, and surroundings most favourable to the impression I wish to make; I shall, so to speak, summon all nature as witness to our conversations; I shall call upon the eternal God, the Creator of nature, to bear witness to the truth of what I say. He shall judge between Emile and myself; I will make the rocks, the woods, the mountains round about us, the monuments of his promises and mine; eyes, voice, and gesture shall show the enthusiasm I desire to inspire. Then I will speak and he will listen, and his emotion will be stirred by my own. The more impressed I am by the sanctity of my duties, the more sacred he will regard his own. I will enforce the voice of reason with images and figures, I will not give him long-winded speeches or cold precepts, but my overflowing feelings will break their bounds; my reason shall be grave and serious, but my heart cannot speak too warmly. Then when I have shown him all that I have done for him, I will show him how he is made for me; he will see in my tender affection the cause of all my care. How greatly shall I surprise and disturb him when I change my tone. Instead of shrivelling up his soul by always talking of his own interests, I shall henceforth speak of my own; he will be more deeply touched by this. I will kindle in his young heart all the sentiments of affection, generosity, and gratitude which I have already called into being, and it will indeed be sweet to watch their growth. I will press him to my bosom, and weep over him in my emotion; I will say to him: "You are my wealth, my child, my handiwork; my happiness is bound up in yours; if you frustrate my hopes, you rob me of twenty years of my life, and you bring my grey hairs with sorrow to the grave." This is the way to gain a hearing and to impress what is said upon the heart and memory of the young man.
