“The time has passed for our sensations in painting to be whispered. We wish them in the future to sing and re-echo upon our canvasses in deafening and triumphant flourishes.”
As quoted in Futurism, ed. Didier Ottinger; Centre Pompidou / 5 Continents Editions, Milan, 2008, p. 132.

The Value of Science (1955)
Context: We are at the very beginning of time for the human race. It is not unreasonable that we grapple with problems. But there are tens of thousands of years in the future. Our responsibility is to do what we can, learn what we can, improve the solutions, and pass them on.
... It is our responsibility to leave the people of the future a free hand. In the impetuous youth of humanity, we can make grave errors that can stunt our growth for a long time. This we will do if we say we have the answers now, so young and ignorant as we are. If we suppress all discussion, all criticism, proclaiming "This is the answer, my friends; man is saved!" we will doom humanity for a long time to the chains of authority, confined to the limits of our present imagination. It has been done so many times before.
... It is our responsibility as scientists, knowing the great progress which comes from a satisfactory philosophy of ignorance, the great progress which is the fruit of freedom of thought, to proclaim the value of this freedom; to teach how doubt is not to be feared but welcomed and discussed; and to demand this freedom as our duty to all coming generations.

Music and Moonlight (1874), Ode
Context: But we, with our dreaming and singing,
Ceaseless and sorrowless we!
The glory about us clinging
Of the glorious futures we see,
Our souls with high music ringing:
O men! it must ever be
That we dwell, in our dreaming and singing,
A little apart from ye.
We are afar with the dawning
And the suns that are not yet high,
And out of the infinite morning
Intrepid you hear us cry —
How, spite of your human scorning,
Once more God's future draws nigh,
And already goes forth the warning
That ye of the past must die.
