“One cannot reflect for long on moral precepts without being astonished at seeing them, at one and the same time, revered and neglected, and without wondering what could be the reason for this vagary of the human heart, whereby it clings to principles of goodness and perfection from which it deviates in practice.”
On ne peut réfléchir sur les precepts de la morale sans être étonné de les voir tout à la fois estimés et négligés; et l'on se demande la raison de cette bizarrerie du cœur humain, qui lui fait goûter des idées de bien et de perfection dont il s'éloigne dans la pratique.

The Sun My Heart (1996)
Context: There is no phenomenon in the universe that does not intimately concern us, from a pebble resting at the bottom of the ocean, to the movement of a galaxy millions of light years away. Walt Whitman said, "I believe a blade of grass is no less than the journey-work of the stars...." These words are not philosophy. They come from the depths of his soul. He also said, "I am large, I contain multitudes." This might be called a meditation on "interfacing endlessly interwoven." All phenomena are interdependent. When we think of a speck of dust, a flower, or a human being, our thinking cannot break loose from the idea of unity, of one, of calculation. We see a line drawn between one and many, one and not one. But if we truly realize the interdependent nature of the dust, the flower, and the human being, we see that unity cannot exist without diversity. Unity and diversity interpenetrate each other freely. Unity is diversity, and diversity is unity. This is the principle of interbeing.
