English physician, named William Harvey, had discovered the circulation of the blood and its laws. I am convinced that as the movement of the heart makes a sound that we can hear, the movement of the blood in our veins must make a sound too, but one which we can very seldom hear. In times when we are perfectly healthy we are in perfect harmony, in times of sickness we are discordant. I told my father that the ringing we have in our ears must surely be a note that has broken loose from the general harmony. My father considers rather that it was an acoustic illusion when we thought we heard such sounds, but I cannot accept that view. You see there is really a great truth contained in the common saying that we can hear the grass grow. All through nature there is regular movement of moisture, and wherever there is movement there is sound and tone. Among the stars, in the depths of the earth, and on the surface, there is an eternal murmur and swell and clash. Music is the soul of the universe, is our soul. All is in million-voiced harmony, and the articulation given to man is its divinest revelation."
Olympia's expression of countenance grew brighter and brighter, and Spinoza said:
"You see I do not laugh at you. I am glad you evaded so well your father's view of it, which yet you so nearly agreed with. I will not allow myself to judge so hastily of your theory."
