Knowledge progresses in a straight line, one discovery, one invention and one fact at a time. People in the past weren’t as scientific as we are today, despite our romanticizing the “good old days”. Aristotle observed the Sun rising and setting everyday, to conclude that the Sun revolves around the Earth. We do not read Aristotle’s scientific theories today. Instead we read the works of Copernicus, Kepler and Newton – stalwarts who stood on Aristotle’s shoulders.
Wisdom is cyclical. It is rediscovered in every era. The best works of wisdom are also the oldest – The Bhagavad Gita, the teachings of the Buddha and Stoic philosophy. How we ought to live our lives is an old question, with old answers. We continue to read Aristotle for his wisdom.
If you in search of knowledge, pick up the latest book on the topic. If you seek wisdom, look for the oldest book that is still around.
