Value of Reflection
The quote implies that true understanding and wisdom come from thoughtful reflection, not from automatic skepticism or acceptance.
Philosophical Balance
Poincaré advocates for a balanced approach—neither believing nor doubting everything, but considering each idea carefully.
Relevance in Science and Life
