One sees clearly only with the heart. Anything essential is invisible to the eyes.
Saint-Exupéry isn't arguing for mere sentimentality—he's pointing out that our most reliable instrument for truth is actually our capacity to *care*. A parent watching a child struggle at school sees failure through the eyes; the heart sees potential, worthiness, and the particular texture of that child's courage. The paradox cuts deeper than "love conquers all": he's suggesting that without emotional investment, we're essentially blind to what matters, collecting facts while missing meaning. We might know every statistic about someone's life and still not truly see them.
