one of my very passages from trotsky, the language is a bit, well dodgy translation from early C20 Russian ,but the point remains the same. From the end of Literature & Revolution:
[after the revolutuion] More than that. Man at last will begin to harmonize himself in earnest. He will make it his business to achieve beauty by giving the movement of his own limbs the utmost precision, purposefulness and economy in his work, his walk and his play....Man will make it his purpose to master his own feelings, to raise his instincts to the heights of consciousness, to make them transparent, to extend the wires of his will into hidden recesses, and thereby to raise himself to a new plane.
It is difficult to predict the extent of self-government which the man of the future may reach or the heights to which he may carry his technique. Social construction and psycho-physical self-education will become two aspects of one and the same process. All the arts—literature, drama, painting, music and architecture will lend this process beautiful form. More correctly, the shell in which the cultural construction and self-education of Communist man will be enclosed, will develop all the vital elements of contemporary art to the highest point. Man will become immeasurably stronger, wiser and subtler; his body 'will become more harmonized, his movements more rhythmic, his voice more musical. The forms of life will become dynamically dramatic. The average human type will rise to the heights of an Aristotle, a Goethe, or a Marx. And above this ridge new peaks will rise.
