“The art of life is more like the wrestler's art than the dancer's, in respect of this, that it should stand ready and firm to meet onsets which are sudden and unexpected.”
VII, 61

Context: Fools, art is a heavy task, more heavy than gold crowns;
it's far more difficult to match firm words than armies,
they're disciplined troops, unconquered, to be placed in rhythm,
the mind's most mighty foe, and not disperse in air.
I'd give, believe me, a whole land for one good song,
for I know well that only words, that words alone,
like the high mountains, have no fear of age or death.

“It should be said that such an art would be neither more false nor more true than classical art.”
Cubism was born

As quoted in Modern Dancing and Dancers (1912) by John Ernest Crawford Flitch, p. 105.
Context: To seek in nature the fairest forms and to find the movement which expresses the soul of these forms — this is the art of the dancer. It is from nature alone that the dancer must draw his inspirations, in the same manner as the sculptor, with whom he has so many affinities. Rodin has said: "To produce good sculpture it is not necessary to copy the works of antiquity; it is necessary first of all to regard the works of nature, and to see in those of the classics only the method by which they have interpreted nature." Rodin is right; and in my art I have by no means copied, as has been supposed, the figures of Greek vases, friezes and paintings. From them I have learned to regard nature, and when certain of my movements recall the gestures that are seen in works of art, it is only because, like them, they are drawn from the grand natural source.
My inspiration has been drawn from trees, from waves, from clouds, from the sympathies that exist between passion and the storm, between gentleness and the soft breeze, and the like, and I always endeavour to put into my movements a little of that divine continuity which gives to the whole of nature its beauty and its life.
