What this quote means
Philosophical ideas often shift in relevance and meaning over time, with what was once deemed foolish sometimes becoming wise as perspectives change.
This quote by William Osler reflects the dynamic nature of wisdom and philosophy through the ages. It suggests that ideas and beliefs that are considered rational or wise in one generation may be viewed as absurd or foolish in the next, while those deemed foolish can later be recognized as insightful. This highlights the importance of perspective and the evolving nature of knowledge, reminding us that what we understand today may not hold the same value in the future.
