Quote by John Maynard Keynes
A study of the history of opinion is a necessary preliminary to the emancipation of the mind.
Summary
This quote suggests that in order to free our minds and think independently, it is crucial to examine the evolution of thoughts and ideas throughout history. By studying the history of opinion, we gain insights into the various perspectives and ideologies that have shaped society. This enables us to challenge existing beliefs, question authority, and develop our own informed opinions. Understanding the patterns and trends of past opinions helps us avoid biases and broaden our intellectual horizons, ultimately leading to a more liberated and critical mindset.
