Final answer:
Adam Smith's ideas were influenced by the Enlightenment, mercantilism, and his own views on economic liberalism but could not have been influenced by the Communist Manifesto, which was published after his time.
Step-by-step explanation:
Smith's ideas could have been influenced by all of these EXCEPT the Communist Manifesto.
Adam Smith, a leading figure during the Enlightenment, introduced the concept of a free market economy as outlined in his seminal work, The Wealth of Nations. Smith argued against the mercantilist system, which was prevalent before his time, proposing instead that trade should be liberalized, which would benefit individuals and nations through the principles of comparative advantage and the operation of an invisible hand in the marketplace.
While Smith was a proponent of economic liberalism, and his principles closely aligned with Enlightenment values, they are clearly at odds with the Communist Manifesto, which Karl Marx and Friedrich Engels wrote in 1848. This document criticized capitalist systems and advocated for a society centered on social ownership of the means of production, a view contradictory to Smith's advocacy for a laissez-faire economy. Moreover, Smith’s ideas were formed and published well before the Industrial Revolution fully took hold and prior to the Communist Manifesto's publication, meaning Smith could not have been influenced by it.
