"It was as failure both in perspective and lesson by lesson that Adams himself saw his education. Success is not the propitious term for education unless the lesson wanted is futile. Education has no term and if arrested at all is only arrested by impassable failure. Surely the dominant emotion of an education, when its inherent possibilities are compared with those it achieved, must strike the honest heart as the emotion of failure. The failure is not of knowledge or of feeling. It is the failure of the ability to react correctly or even intelligently to more than an abbreviated version of knowledge and feeling: failure in the radical sense that we cannot consciously react to more than a minor fraction of the life we yet deeply know and endure and die. It is the failure the mind comes to ultimately and all along when it is compelled to measure its knowledge in terms of its ignorance."
