“Our system of philosophy is itself on trial; it must stand or fall according as it is broad enough to find room for this experience as an element of life.”

The Futurist Reconstruction of the Universe http://www.italianfuturism.org/manifestos/futurist-reconstruction-of-the-universe/ Manifesto with Giacomo Balla, in: Direzione del Movimento Futurista, March 11, 1915. Translation by Caroline Tisdall, 1973.
Context: We Futurists, Balla and Depero, seek to realize this total fusion in order to reconstruct the universe by making it more joyful, in other words by an integral re-creation. 'We will give skeleton and flesh to the invisible, the impalpable, the imponderable and the imperceptible. We will find abstract equivalents for all the forms and elements of the universe, and then well will combine them according to the caprice of our inspiration, to shape plastic complexes which we will set in motion.

On Certainty (1969)
Context: 105. All testing, all confirmation and disconfirmation of a hypothesis takes place already within a system. And this system is not a more or less arbitrary and doubtful point of departure for all our arguments; no it belongs to the essence of what we call an argument. The system is not so much the point of departure, as the element in which our arguments have their life.

Vague Thoughts On Art (1911)
Context: I cannot help thinking that historians, looking back from the far future, will record this age as the Third Renaissance. We who are lost in it, working or looking on, can neither tell what we are doing, nor where standing; but we cannot help observing, that, just as in the Greek Renaissance, worn-out Pagan orthodoxy was penetrated by new philosophy; just as in the Italian Renaissance, Pagan philosophy, reasserting itself, fertilised again an already too inbred Christian creed; so now Orthodoxy fertilised by Science is producing a fresh and fuller conception of life — a love of Perfection, not for hope of reward, not for fear of punishment, but for Perfection's sake. Slowly, under our feet, beneath our consciousness, is forming that new philosophy, and it is in times of new philosophies that Art, itself in essence always a discovery, must flourish. Those whose sacred suns and moons are ever in the past, tell us that our Art is going to the dogs; and it is, indeed, true that we are in confusion! The waters are broken, and every nerve and sinew of the artist is strained to discover his own safety. It is an age of stir and change, a season of new wine and old bottles. Yet, assuredly, in spite of breakages and waste, a wine worth the drinking is all the time being made.
