Another thing wherein they shew their love of dominion, is, their desire to have things to be theirs: They would have propriety and possession, pleas… - John Locke

But the business of laws is not to provide for the truth of opinions, but for the safety and security of the commonwealth and of every particular man's goods and person.

Begin therefore betimes nicely to observe your son's temper; and that, when he is under least restraint, in his play, and as he thinks out of your sight. See what are his predominate passions and prevailing inclinations; whether he be fierce or mild, bold or bashful, compassionate or cruel open or reserv'd, &c. For as these are different in him, so are your methods to be different, and your authority must hence take measures to apply itself different ways to him. These native propensities, these prevalencies of constitution, are not to be cur'd by rules, or a direct contest, especially those of them that are the humbler or meaner sort, which proceed from fear, and lowness of spirit: though with art they may be much mended, and turn'd to good purposes. But this be sure, after all is done, the bypass will always hang on that side that nature first plac'd it: And if you carefully observe the characters of his mind, now in the first scenes of his life, you will ever after be able to judge which way his thoughts lean, and what he aims at even hereafter, when, as he grows up, the plot thickens, and he puts on several shapes to act it.

One thing I have frequently observed in children, that when they have got possession of any poor creature, they are apt to use it ill: they often torment, and treat it very roughly, young birds, butterflies, and such other poor animals which fall into their hands, and that with a seeming kind of pleasure. This I think should be watched in them, and if they incline to any such cruelty, they should be taught the contrary usage. For the custom of tormenting and killing of beasts, will, by degrees, harden their minds even towards men; and they will delight in the suffering and destruction of inferior creatures, will not be apt to be very compassionate or benign to those of their own kind. Our practice takes notice of this in the exclusion of butchers from juries of life and death.
