Classical liberalism is one of the most important political and social ideals. In fact, this idea was crucial for the development of the modern world we live in today. Economies thrived unimpeded while governments were restricted in their freedom of action. This resulted in the tremendous improvement of living standards over the last two centuries. However, classical liberalism is often misunderstood. This is also due to the significant changes in interpretation over the years. Eamonn Butler makes a valuable contribution to a better understanding of the perspective as it was originally and how it is now applied through his clear and contemporary introduction. Classical liberalism is experiencing a long-overdue resurgence, and the topic is more relevant than ever.
