“A very young child has no self-command; but, whatever are its emotions, whether fear, or grief, or anger, it endeavours always, by the violence of its outcries, to alarm, as much as it can, the attention of its nurse, or of its parents. While it remains under the custody of such partial protectors, its anger is the first and, perhaps, the only passion which it is taught to moderate. By noise and threatening they are, for their own ease, often obliged to frighten it into good temper; and the passion which incites it to attack, is restrained by that which teaches it to attend to its own safety. When it is old enough to go to school, or to mix with its equals, it soon finds that they have no such indulgent partiality. It naturally wishes to gain their favour, and to avoid their hatred or contempt. Regard even to its own safety teaches it to do so; and it soon finds that it can do so in no other way than by moderating, not only its anger, but all its other passions, to the degree which its play-fellows and companions are likely to be pleased with. It thus enters into the great school of self-command, it studies to be more and more master of itself, and begins to exercise over its own feelings a discipline which the practice of the longest life is very seldom sufficient to bring to complete perfection.”

“Pleasure and pain are the great objects of desire and aversion: but these are distinguished not by reason, but by immediate sense and feeling. If virtue, therefore, be desirable for its own sake, and if vice be, in the same manner, the object of aversion, it cannot be reason which originally distinguishes those different qualities, but immediate sense and feeling.”
― Adam Smith, The Theory of Moral Sentiments

“The great pleasure of conversation and society, besides, arises from a certain correspondence of sentiments and opinions, from a certain harmony of minds, which like so many musical instruments coincide and keep time with one another. But this most delightful harmony cannot be obtained unless there is a free communication of sentiments and opinions. We all desire, upon this account, to feel how each other is affected, to penetrate into each other's bosoms, and to observe the sentiments and affections which really subsist there. The man who indulges us in this natural passion, who invites us into his heart, who, as it were, sets open the gates of his breast to us, seems to exercise a species of hospitality more delightful than any other. No man, who is in ordinary good temper, can fail of pleasing, if he has the courage to utter his real sentiments as he feels them, and because he feels them. It is this unreserved sincerity which renders even the prattle of a child agreeable.”
― Adam Smith, Theory of Moral Sentiments

“The most notorious liar, I am disposed to believe, tells the fair truth at least twenty times for once that he seriously and deliberately lies; and, as in the most cautious the disposition to believe is apt to prevail over that to doubt and distrust; so in those who are the most regardless of truth, the natural disposition to tell it prevails upon most occasions over that to deceive, or in any respect to alter or disguise it.”
