Do not grow old, no matter how long you live. Never cease to stand like curious children before the Great Mystery into which we were born.
The truth is, we know so little about life, we don't really know what the good news is and what the bad news is.
Human life is beyond comprehension.
Life, not death, is the great mystery you must confront.
The whole of life is just like watching a film. Only it's as though you always get in ten minutes after the big picture has started, and no-one will tell you the plot, so you have to work it out all yourself from the clues.
We are born in mystery, we live in mystery, and we die in mystery.
The secret of life does not lie in its chemical basis . . . Life succeeds precisely because it evades chemical imperatives.
Life's perhaps the only riddle That we shrink from giving up.
The ultimate gift of conscious life is a sense of the mystery that encompasses it.
Everything is prospective, and man is to live hereafter. That the world is for his education is the only sane solution of the enigma.
How strange a scene is this in which we are such shifting figures, pictures, shadows. The mystery of our existence--I have no faith in any attempted explanation of it. It is all a dark, unfathomed profound.
Some things cannot be explained. This is part of the magic of life. There cannot be a word or an idea or a definition attached to everything.
We all feel the riddle of the earth without anyone to point it out. The mystery of life is the plainest part of it. The clouds and curtains of darkness, the confounding vapors, these are the daily weather of this world.
