But though all the general rules of art are founded only on experience and on the observation of the common sentiments of human nature, we must not imagine, that, on every occasion, the feelings of men will be conformable to these rules.
David Hume
These rules will enable you to have a free and sound judgment; since good judgment is born of clear understanding, and a clear understanding comes of reasons derived from sound rules, and sound rules are the issue of sound experience — the common mother of all the sciences and arts. Hence, bearing in mind the precepts of my rules, you will be able, merely by your amended judgment, to criticise and recognise every thing that is out of proportion in a work, whether in the perspective or in the figures or any thing else.
Leonardo da Vinci
All I know is that I'm young and your rules they are old
If I've got to kill to live then there's something left untold
I'm no statesman I'm no general. I'm no kid I'll never be
It's the rules not the soldier that I find the real enemy.Bob Seger
I've argued that many of what philosophers call moral sentiments can be seen in other species. In chimpanzees and other animals, you see examples of sympathy, empathy, reciprocity, a willingness to follow social rules. Dogs are a good example of a species that have and obey social rules; that's why we like them so much, even though they're large carnivores.
Frans de Waal
Though the principles of the banking trade may appear somewhat abstruse, the practice is capable of being reduced to strict rules. To depart upon any occasion from these rules, in consequence of some flattering speculation of extraordinary gain, is almost always extremely dangerous, and frequently fatal to the banking company which attempts it.
Adam Smith
Human nature is evil, and goodness is caused by intentional activity. A person is born with a liking for profit. If he gives way to this, it will lead him to quarrels and conflicts, and any [acquired] sense of courtesy and humility will be abandoned. A person is born with feelings of envy and hate. If he gives way to them, they will lead him to violence and crime, and any [acquired] sense of loyalty and good faith will be abandoned. A person is born with desires of the eyes and ears, and a liking for beautiful sights and sounds. If he gives way to them, they will lead him to immorality and lack of restriction, and any [acquired] ritual principles and propriety will be abandoned. Thus, anybody who follows this nature and gives way its states will be led into quarrels and conflicts, and go against the conventions and rules of society, and will end up a criminal. Therefore, a person should first be changed by a teacher's instructions, and guided by principles of ritual. Only then can he observe the rules of courtesy and humility, obey the conventions and rules of society, and achieve order.
