Explanation:

Adam Smith is a 18th-century philosopher of the Enlightenment period who is most well-known for his notion of the "invisible hand" of the market. He believed that the economic propensities of individuals were the best way upon which to organize society and that by nature human beings will do what most benefits them individually in economic terms and that this will lead to a better society overall rather than trying to impose unnatural conditions from above. The invisible hand is the concept that there can be social benefits from an individual's self-interested actions even if they are unintentional. This idea was introduced in The Theory of Moral Sentiments, written in 1759, where Smith is trying to explain the logic of income distribution.
