The softer you find your child is, the more you are to seek occasions, at fit times, thus to harden him. The great art in this is, to begin with what is but very little painful, and to proceed by insensible degrees, when you are playing, and in good humour with him, and speaking well of him: and when you have once got him to think himself made amends for his suffering by the praise is given him for his courage; when he can take pride in giving such marks of his manliness, and can prefer the reputation of being brave and stout, to the avoiding a little pain, or the shrinking under it; you need nor despair in time and by the assistance of his growing reason, to master his timorousness, and mend the weakness of his constitution.
