Introduction to Adam Smith's 'Invisible Hand'

Often, we delve into Adam Smith's works under the assumption that he had a clear, comprehensive theory of economics from the onset. However, a closer examination reveals that his understanding of the 'invisible hand' evolved over time, influenced by the intellectual context of his era and his own philosophical beliefs.

Background and Context

Adam Smith, living during the latter part of the 18th century, was part of a period marked by significant scientific advancements, notably the work of Isaac Newton. The transition from theological to mechanistic explanations had a profound impact on the way people viewed the world around them. Newton's theories of gravity exemplified the concept of an 'invisible hand,' a force that operates behind the scenes without direct intervention. Smith, heavily influenced by this context, adopted and expanded on this idea within his own works.

Smith's Early Works: 'The Theory of Moral Sentiments'

Before The Wealth of Nations, Smith published The Theory of Moral Sentiments in 1759. In this work, he explores the development of moral sensibilities in society. Smith posits that our sense of right and wrong is not inherently encoded within us by a divine being but is instead shaped by our interactions with others. This social interdependence becomes an 'invisible hand' guiding our moral decisions.

The Emergence of the 'Invisible Hand' Concept

In The Wealth of Nations, first published in 1776, Smith introduces the concept of the 'invisible hand' to explain the efficiency of free markets. However, it's important to note that this was more of an observational note than a theoretical explanation. Smith recognized the visible hand of the sovereign and its role in establishing and regulating enterprise, but he also believed that free markets could operate effectively without such direct intervention.

The Practical Application of the 'Invisible Hand'

The 'invisible hand' concept in economics operates on the principle that individuals, in pursuit of their own self-interest, can inadvertently achieve societal benefits. This is particularly evident in how Smith uses the mechanism of supply and demand. Even though each individual may be motivated by personal gain, the interaction of supply and demand leads to a market equilibrium that is beneficial for everyone.

Comparison to Current Thinkers

Smith's 'invisible hand' concept can be likened to that of Donald Rumsfeld, who famously articulated the idea of 'known knowns,' 'unknown knowns,' and 'unknown unknowns.' Just as Rumsfeld highlighted the limitations of our knowledge, Smith acknowledged that free markets can be complex and unpredictable. However, this unpredictability does not render them ineffective; rather, it suggests that they can self-regulate and adjust to changing circumstances without direct oversight.

Conclusion

In conclusion, Adam Smith's 'invisible hand' theory is rooted in a deep understanding of human nature, driven by both rationality and social interaction. It challenges the notion of a 'visible hand' and instead advocates for the efficiency and self-regulation of free markets. Understanding this historical context can help us appreciate the complexity and subtlety of Smith's economic philosophy and its enduring relevance in modern times.
