I do not know everything; still many things I understand.

The line balances humility with hard-won insight. By admitting she does not “know everything,” the speaker rejects omniscience and the pretense of total certainty; yet the second clause insists that partial understanding is real and valuable. The quote affirms a mature epistemology: human knowledge is limited, but meaning can still be grasped in fragments—through experience, attention, and faithfulness to what one has learned. In L’Engle’s broader intellectual and spiritual sensibility, such a stance often functions as a defense of wonder and inquiry: not knowing is not failure, but the condition that makes learning, imagination, and reverence possible.
