Context: "Why?" Dallben interrupted. "In some cases," he said, "we learn more by looking for the answer to a question and not finding it than we do from learning the answer itself."
“Bromidic though it may sound, some questions don't have answers, which is a terribly difficult lesson to learn.”

The Books in My Life (1952) Preface (2nd edition. New York: New Directions Publishing, 1969, p. 12)

Preface
Personal Reminiscences of Henry Irving (1907)
Context: Logically speaking, even the life of an actor has no preface. He begins, and that is all. And such beginning is usually obscure; but faintly remembered at the best. Art is a completion; not merely a history of endeavour. It is only when completeness has been obtained that the beginnings of endeavour gain importance, and that the steps by which it has been won assume any shape of permanent interest. After all, the struggle for supremacy is so universal that the matters of hope and difficulty of one person are hardly of general interest. When the individual has won out from the huddle of strife, the means and steps of his succeeding become of interest, either historically or in the educational aspect — but not before. From every life there may be a lesson to some one; but in the teeming millions of humanity such lessons can but seldom have any general or exhaustive force. The mere din of strife is too incessant for any individual sound to carry far. Fame, who rides in higher atmosphere, can alone make her purpose heard. Well did the framers of picturesque idea understand their work when in her hand they put a symbolic trumpet.

Miranda v. Arizona, 384 U. S. 436, 445 (1965) - Opinion of the Court
Context: Prior to any questioning, the person must be warned that he has a right to remain silent, that any statement he does make may be used as evidence against him, and that he has a right to the presence of an attorney, either retained or appointed. The defendant may waive effectuation of these rights, provided the waiver is made voluntarily, knowingly and intelligently. If, however, he indicates in any manner and at any stage of the process that he wishes to consult with an attorney before speaking there can be no questioning. Likewise, if the individual is alone and indicates in any manner that he does not wish to be interrogated, the police may not question him. The mere fact that he may have answered some questions or volunteered some statements on his own does not deprive him of the right of refrain from answering any further inquiries until he has consulted with an attorney and thereafter consents to be questioned.
