“Without rhetorical exaggeration, a simply truthful combination of the miseries that have overwhelmed the noblest of nations and polities, and the finest exemplars of private virtue, forms a picture of most fearful aspect, and excites emotions of the profoundest and most hopeless sadness, counterbalanced by no consolatory result. We endure in beholding it a mental torture, allowing no defence or escape but the consideration that what has happened could not be otherwise; that it is a fatality which no intervention could alter. And at last we draw back from the intolerable disgust with which these sorrowful reflections threaten us, into the more agreeable environment of our individual life the Present formed by our private aims and interests. In short we retreat into the selfishness that stands on the quiet shore, and thence enjoys in safety the distant spectacle of "wrecks confusedly hurled." But even regarding History as the slaughter-bench at which the happiness of peoples, the wisdom of States, and the virtue of individuals have been victimised the question involuntarily arises to what principle, to what final aim these. enormous sacrifices have been offered.”

Canto I, Stanza 55.
The Castle of Indolence (1748)

Variant translations: The fairest thing we can experience is the mysterious. It is the fundamental emotion which stands at the cradle of true art and true science. He who knows it not and can no longer wonder, no longer feel amazement, is as good as dead, a snuffed-out candle. It was the experience of mystery — even if mixed with fear — that engendered religion. A knowledge of the existence of something we cannot penetrate, of the manifestations of the profoundest reason and the most radiant beauty, which are only accessible to our reason in their most elementary forms — it is this knowledge and this emotion that constitute the truly religious attitude; in this sense, and in this alone, I am a deeply religious man.
The finest emotion of which we are capable is the mystic emotion. Herein lies the germ of all art and all true science. Anyone to whom this feeling is alien, who is no longer capable of wonderment and lives in a state of fear is a dead man. To know that what is impenetrable for us really exists and manifests itself as the highest wisdom and the most radiant beauty, whose gross forms alone are intelligible to our poor faculties — this knowledge, this feeling … that is the core of the true religious sentiment. In this sense, and in this sense alone, I rank myself among profoundly religious men.
As quoted in After Einstein : Proceedings of the Einstein Centennial Celebration (1981) by Peter Barker and Cecil G. Shugart, p. 179
The most beautiful thing we can experience is the mysterious. It is the source of all true art and science. He to whom this emotion is a stranger, who can no longer pause to wonder and stand rapt in awe, is as good as dead: his eyes are closed.
As quoted in Introduction to Philosophy (1935) by George Thomas White Patrick and Frank Miller Chapman, p. 44
The most beautiful emotion we can experience is the mysterious. It is the fundamental emotion that stands at the cradle of all true art and science. He to whom this emotion is a stranger, who can no longer wonder and stand rapt in awe, is as good as dead, a snuffed-out candle. To sense that behind anything that can be experienced there is something that our minds cannot grasp, whose beauty and sublimity reaches us only indirectly: this is religiousness. In this sense, and in this sense only, I am a devoutly religious man."
He who can no longer pause to wonder and stand rapt in awe, is as good as dead; his eyes are closed.
1930s, Mein Weltbild (My World-view) (1931)
Context: The most beautiful experience we can have is the mysterious. It is the fundamental emotion that stands at the cradle of true art and true science. Whoever does not know it and can no longer wonder, no longer marvel, is as good as dead, and his eyes are dimmed. It was the experience of mystery — even if mixed with fear — that engendered religion. A knowledge of the existence of something we cannot penetrate, our perceptions of the profoundest reason and the most radiant beauty, which only in their most primitive forms are accessible to our minds: it is this knowledge and this emotion that constitute true religiosity. In this sense, and only this sense, I am a deeply religious man.
