“I would rather have questions that can't be answered than answers that can't be questioned.”
― Richard Feynman

“We absolutely must leave room for doubt or there is no progress and there is no learning. There is no learning without having to pose a question. And a question requires doubt. People search for certainty. But there is no certainty. People are terrified — how can you live and not know? It is not odd at all. You only think you know, as a matter of fact. And most of your actions are based on incomplete knowledge and you really don't know what it is all about, or what the purpose of the world is, or know a great deal of other things. It is possible to live and not know.”
― Richard P. Feynman, The Pleasure of Finding Things Out: The Best Short Works of Richard P. Feynman

“My life, I resolved, ought to be a perpetual transcending, a progression from stage to stage; I wanted it to pass through one area after the next, leaving each behind, as music moves on from theme to theme, from tempo to tempo, playing each out to the end, completing each and leaving it behind, never tiring, never sleeping, forever wakeful, forever in the present. In connection with the experiences of awakening, I had noticed that such stages and such areas exist, and that each successive period in one’s life bears within itself, as it is approaching its end, a note of fading and eagerness for death. That in turn leads to a shifting to a new area, to awakening and new beginnings.”
― Hermann Hesse, The Glass Bead Game

“Nothing is harder yet nothing is more necessary, than to speak of certain things whose existence is neither demonstrable nor probable. The very fact that serious and conscientious men treat them as existing things brings them a step closer to existence and to the possibility of being born.
