It is "not out of benevolence that" dentists clean and repair teeth, but "from their regard for their own self-interest".
Adam Smith was a Scottish political economist. He has turned out to be popular by his compelling book The Wealth of Nations in 1776. A significant part of the reasoning behind Smith's work depends on self-intrigue and amplifying return, "The Theory of Moral Sentiments," was a treatise about how human correspondence depends on sympathy. In the book, Smith contended that individuals are self-intrigued yet normally like to help other people.
Based on the ideas of Adam Smith, it is not out of benevolence that dentists clean and repair teeth, but from their regard for their own self-interest.
