“The first thing that experience finds to do is to free us from the phantoms of the brain—those false notions that have been put into us in youth.”

“a man may have a great mass of knowledge, but if he has not worked it up by thinking it over for himself, it has much less value than a far smaller amount which he has thoroughly pondered.”

“by the constant growth of insight and knowledge, this intellectual life, like a slowly-forming work of art, will acquire a consistency, a permanent intensity, a unity which becomes ever more and more complete”
The image treats intellectual development as cumulative craftsmanship: insight and knowledge gradually produce greater coherence instead of appearing as a single finished achievement.
