If you punish him for what he sees you practise yourself, he... will be apt to interpret it the peevishness and arbitrary imperiousness of a father, who, without any ground for it, would deny his son the liberty and pleasure he takes himself.

He would be laughed at, that should go about to make a fine dancer out of a country hedger, at past fifty. And he will not have much better success, who shall endeavour, at that age, to make a man reason well, or speak handsomely, who has never been used to it, though you should lay before him a collection of all the best precepts of logic or oratory.

A sound mind in a sound body, is a short, but full description of a happy state in this World: he that has these two, has little more to wish for; and he that wants either of them, will be little the better for anything else.

Where all is but dream, reasoning and arguments are of no use, truth and knowledge nothing.
