“It is the duty to carry on, under stress, the search for understanding.”

Context: That the threat is now intense is not a reason to abandon our quest for knowledge. It is a reason to hold it more tightly, in spite of the need for action to preserve our freedom, in spite of the distractions of living in turmoil, that it may not be lost or brushed aside by the demands of the hour. We would not neglect our duty to our country and our fellows to strive mightily to preserve our ways and our lives. There is an added duty, not inconsistent, not less. It is the duty to so live that there may be a reason for living, beyond the mere mechanisms of life. It is the duty to carry on, under stress, the search for understanding.

Context: It is the duty of the human understanding to understand that there are things which it cannot understand, and what those things are. Human understanding has vulgarly occupied itself with nothing but understanding, but if it would only take the trouble to understand itself at the same time it would simply have to posit the paradox.
