What this quote means

This quote by Fontenelle highlights that intellectual certainty is a trap. When we believe we possess the truth, we stop searching, questioning, and opening ourselves to new perspectives. Ignorance is not the main obstacle, but the illusion of knowledge. It resonates in our era where opinions are often rigid. It invites us to intellectual humility and permanent curiosity, to continue learning and growing.

How to apply it daily

Challenge one of your certainties by actively seeking information that contradicts it, and welcome what you learn with openness.
