"Music would take over at the point at which words become powerless, with the one and only object of expressing that which nothing but music could express. For this, I need a text by a poet who, resorting to discreet suggestion rather than full statement, will enable me to graft my dream upon his dream — who will give me plain human beings in a setting belonging to no particular period or country. … Then I do not wish my music to drown the words, nor to delay the course of the action. I want no purely musical developments which are not called for inevitably by the text. In opera there is always too much singing. Music should be as swift and mobile as the words themselves."

“How much has to be explored and discarded before reaching the naked flesh of feeling.”

“People don't very much like things that are beautiful — they are so far from their nasty little minds.”

“I wish to write down my musical dreams in a spirit of utter self-detachment. I wish to sing of my interior visions with the naïve candour of a child. No doubt, this simple musical grammar will jar on some people. It is bound to offend the partisans of deceit and artifice. I foresee that and rejoice at it. I shall do nothing to create adversaries, but neither shall I do anything to turn enmities into friendships. I must endeavour to be a great artist so that I may dare to be myself and suffer for my faith. Those who feel as I do will only appreciate me more. The others will shun and hate me. I shall make no effort to appease them. On that distant day — I trust it is still very far off — when I shall no longer be a cause of strife, I shall feel bitter self-reproach. For that odious hypocrisy which enables one to please all mankind will inevitably have prevailed in those last works.”

“Music is the arithmetic of sounds as optics is the geometry of light.”

“I do not practise religion in accordance with the sacred rites. I have made mysterious Nature my religion. I do not believe that a man is any nearer to God for being clad in priestly garments, nor that one place in a town is better adapted to meditation than another. When I gaze at a sunset sky and spend hours contemplating its marvelous ever-changing beauty, an extraordinary emotion overwhelms me. Nature in all its vastness is truthfully reflected in my sincere though feeble soul. Around me are the trees stretching up their branches to the skies, the perfumed flowers gladdening the meadow, the gentle grass-carpetted earth, … and my hands unconsciously assume an attitude of adoration. … To feel the supreme and moving beauty of the spectacle to which Nature invites her ephemeral guests! … that is what I call prayer.”

“Works of art make rules but rules do not make works of art.”
