Adam Smith is more commonly associated with the Enlightenment than with the Scientific Revolution. However, he can be seen as contributing to the scientific mindset of the time by applying the scientific method to such topics as economics and moral philosophy.
Smith applied an analytical mindset to observing the principles of a free market. Just like previous scientific thinkers like Galileo, Kepler, and Newton, Adam Smith looked for observable natural laws governing his fields of study. In his most well-known work, The Wealth of Nations, Smith applied the scientific method as well as critical observation and reasoning to define the laws of supply and demand. While economics is not a hard science (like physics or astronomy), Smith shows us that it can be governed by observable universal laws. As such, he might be seen as a contributor to the Scientific Revolution in that he shows that scientific laws can be applied to social-scientific topics.
