The quote "He who can go to the fountain does not go to the water-jar" emphasizes the importance of seeking the original source of knowledge or inspiration rather than relying on secondary options. It suggests that those with the means and ability will always prefer to engage directly with the primary source, which in this context can relate to learning, creativity, or capturing ideas directly from their origin.

This philosophy ties into the life and work of Leonardo da Vinci as depicted by Walter Isaacson, where da Vinci’s relentless curiosity and pursuit of direct experience drove his innovations. By prioritizing direct engagement and firsthand exploration over mere collection or imitation, individuals are likely to achieve deeper understanding and achieve greater creative outcomes.
