The World's Religions (1991)
Source: Beyond the Post-Modern Mind: The Place of Meaning in a Global Civilization
Context: In mysteries what we know, and our realization of what we do not know, proceed together; the larger the island of knowledge, the longer the shoreline of wonder. It is like the quantum world, where the more we understand its formalism, the stranger that world becomes.

Variant translation: The more we learn about the world, and the deeper our learning, the more conscious, clear, and well-defined will be our knowledge of what we do not know, our knowledge of our ignorance.

Conjectures and Refutations: The Growth of Scientific Knowledge (1963)
Context: The more we learn about the world, and the deeper our learning, the more conscious, specific, and articulate will be our knowledge of what we do not know, our knowledge of our ignorance. For this, indeed, is the main source of our ignorance — the fact that our knowledge can be only finite, while our ignorance must necessarily be infinite.

Standing by Words: Essays (2011), Poetry and Marriage: The Use of Old Forms (1982)
Context: It may be, then, that form serves us best when it works as an obstruction to baffle us and deflect our intended course. It may be that when we no longer know what to do we have come to our real work and that when we no longer know which way to go we have begun our real journey. The mind that is not baffled is not employed. The impeded stream is the one that sings.
