„There are two aspects of individual harmony: the harmony between body and soul, and the harmony between individuals. All the tragedy in the world, in the individual and in the multitude, comes from lack of harmony. And harmony is the best given by producing harmony in one's own life.“

Kontext: From harmony, from heavenly harmony,
This universal frame began:
When nature underneath a heap
Of jarring atoms lay,
And could not heave her head,
The tuneful voice was heard from high,
'Arise, ye more than dead!'
Then cold, and hot, and moist, and dry,
In order to their stations leap,
And Music's power obey.
From harmony, from heavenly harmony,
This universal frame began:
From harmony to harmony
Through all the compass of the notes it ran,
The diapason closing full in Man.

Kontext: The harmony of music exists equally with the harmony of movement in nature.
Man has not invented the harmony of music. It is one of the underlying principles of life. Neither could the harmony of movement be invented: it is essential to draw one’s conception of it from Nature herself, and to see the rhythm of human movement from the rhythm of water in motion, from the blowing of the winds on the world, in all the earth’s movements, in the motions of animals, fish, birds, reptiles, and even in primitive man, whose body still moved in harmony with nature….. All the movements of the earth follow the lines of wave motion. Both sound and light travel in waves. The motion of water, winds, trees and plants progresses in waves. The flight of a bird and the movements of all animals follow lines like undulating waves. If then one seeks a point of physical beginning for the movement of the human body, there is a clue in the undulating motion of the wave.

The Conduct Of Life (1951)
Kontext: Now life is the only art that we are required to practice without preparation, and without being allowed the preliminary trials, the failures and botches, that are essential for the training of a mere beginner. In life, we must begin to give a public performance before we have acquired even a novice's skill; and often our moments of seeming mastery are upset by new demands, for which we have acquired no preparatory facility. Life is a score that we play at sight, not merely before we have divined the intentions of the composer, but even before we have mastered our instruments; even worse, a large part of the score has been only roughly indicated, and we must improvise the music for our particular instrument, over long passages. On these terms, the whole operation seems one of endless difficulty and frustration; and indeed, were it not for the fact that some of the passages have been played so often by our predecessors that, when we come to them, we seem to recall some of the score and can anticipate the natural sequence of the notes, we might often give up in sheer despair. The wonder is not that so much cacophony appears in our actual individual lives, but that there is any appearance of harmony and progression.

Kontext: The strong man holds in a living blend strongly marked opposites. The idealists are usually not realistic, and the realists are not usually idealistic. The militant are not generally known to be passive, nor the passive to be militant. Seldom are the humble self-assertive, or the self-assertive humble. But life at its best is a creative synthesis of opposites in fruitful harmony. The philosopher Hegel said that truth is found neither in the thesis nor the antithesis, but in the emergent synthesis which reconciles the two.
