Meaning

This observation places human knowledge in a humbling perspective. Everything we have managed to learn, discover, and verify amounts to only a tiny portion of what exists to be understood. The image of a drop against an ocean is deliberately stark: the drop is real and valuable, but its smallness beside the ocean is impossible to ignore. The quote encourages curiosity rather than complacency, suggesting that the honest response to knowledge is not pride but wonder.

Context

Whether or not Newton stated these exact words in this precise form, the sentiment fits naturally with the spirit of his era and his own documented reflections. Newton himself wrote, near the end of his life, that he felt like a child collecting shells on a beach while the great ocean of truth lay undiscovered before him. That image of the shore and the sea appears in accounts of his later years and points toward the same humility this quote expresses. The scientific revolution he helped shape was as much about recognizing the vastness of the unknown as it was about expanding the known.
