Explanation:
Adam Smith is considered the first great theoretician of economic science. In his book The Wealth of Nations (1776) the author defends the idea that the market would regulate automatically - the invisible hand - bringing the economy to equilibrium without the need for state intervention.

Among them, the valuation of the individual and the limitation of the role of the state.
