“I am chained to the earth to pay for the freedom of my eyes.”

Apocalypse (1930)
Context: What man most passionately wants is his living wholeness and his living unison, not his own isolate salvation of his "soul." Man wants his physical fulfillment first and foremost, since now, once and once only, he is in the flesh and potent. For man, the vast marvel is to be alive. For man, as for flower and beast and bird, the supreme triumph is to be most vividly, most perfectly alive. Whatever the unborn and the dead may know, they cannot know the beauty, the marvel of being alive in the flesh. The dead may look after the afterwards. But the magnificent here and now of life in the flesh is ours, and ours alone, and ours only for a time. We ought to dance with rapture that we should be alive and in the flesh, and part of the living, incarnate cosmos. I am part of the sun as my eye is part of me. That I am part of the earth my feet know perfectly, and my blood is part of the sea. My soul knows that I am part of the human race, my soul is an organic part of the great human soul, as my spirit is part of my nation. In my own very self, I am part of my family. There is nothing of me that is alone and absolute except my mind, and we shall find that the mind has no existence by itself, it is only the glitter of the sun on the surface of the waters.

Context: Another revolution! Naples free and all of Italy in insurrection! How wonderful has been the march of the human mind in these last thirty years … so may it be till the last link of the chains of slavery is broken and the banner of freedom waves over the whole earth!

1980s, First term of office (1981–1985), First Inaugural address (1981)
Context: If we look to the answer as to why for so many years we achieved so much, prospered as no other people on earth, it was because here in this land we unleashed the energy and individual genius of man to a greater extent than has ever been done before. Freedom and the dignity of the individual have been more available and assured here than in any other place on earth. The price for this freedom at times has been high, but we have never been unwilling to pay the price.

The Royal Road to Romance (1925).
Context: Youth -- nothing else worth having in the world... and I had youth, the transitory, the fugitive, now, completely and abundantly. Yet what was I going to do with it? Certainly not squander its gold on the commonplace quest for riches and respectability, and then secretly lament the price that had to be paid for these futile ideals. Let those who wish have their respectability -- I wanted freedom, freedom to indulge in whatever caprice struck my fancy, freedom to search in the farthermost corners of the earth for the beautiful, the joyous and the romantic.
