2. Introduction

The Wealth of Nations is widely regarded as the foundational text of modern economics. Published in 1776 by Scottish philosopher Adam Smith, it systematically explores the mechanisms of economic growth, division of labour, free markets, and the role of government. Smith’s work laid the intellectual groundwork for classical economics and continues to influence economic thought, policy, and philosophy. The book’s central thesis is that individual self-interest, guided by competition and markets, drives economic prosperity—a concept famously described as the “invisible hand.”


3. Author Background and Credentials

Adam Smith (1723–1790) was a Scottish moral philosopher and economist, often called the “Father of Economics.” He was a professor at the University of Glasgow and a key figure of the Scottish Enlightenment. Smith’s interdisciplinary approach combined ethics, philosophy, and economics, shaping the study of economic behaviour within social contexts.

5. Critical Evaluation

a. Coherence and Argumentation

Smith presents a coherent and systematic analysis of economic principles with persuasive arguments supporting market mechanisms and limited government intervention.

b. Originality and Intellectual Contribution

The book introduced foundational concepts such as the division of labour, productivity, free markets, and the role of self-interest, fundamentally shaping economics as a discipline.

c. Evidence, Sources, and Method

While based on observation and philosophical reasoning rather than empirical data, Smith’s insights are drawn from extensive reflection on contemporary economic practices.

d. Style and Accessibility

The prose is dense and formal, characteristic of 18th-century scholarship, requiring attentive reading but rewarding with profound insights.

e. Limitations and Critiques

Some concepts are outdated by modern standards; Smith’s views on labour and markets do not fully anticipate industrial and financial complexities of later economies.


6. Comparative Context

Compared with:

  • Karl Marx’s Das Kapital – Marx critiques capitalism that Smith champions
  • John Maynard Keynes’s General Theory – Keynes builds on and challenges classical economics
  • Friedrich Hayek’s The Road to Serfdom – Hayek extends Smith’s advocacy for market freedom

The Wealth of Nations remains the touchstone of classical economic thought.


7. Thematic or Disciplinary Relevance

The book is essential to:

  • Classical economics
  • Political economy
  • Economic philosophy and ethics
  • Public policy and economic development

8. Reflection or Practical Application

Smith’s analysis provides foundational understanding for policymakers, economists, and business leaders regarding the principles underlying market economies.


9. Conclusion

The Wealth of Nations is a monumental work that established the framework for economic science. Its insights into markets, labour, and capital continue to underpin economic discourse and practice worldwide.

Recommended for: Economists, historians of economic thought, policymakers, and students of economics and philosophy.
