“For the philosophy which is so important in each of us is not a technical matter; it is our more or less dumb sense of what life honestly and deeply means. It is only partly got from books; it is our individual way of just seeing and feeling the total push and pressure of the cosmos.”

“Each individual is a cosmos of organs, each organ is a cosmos of cells, each cell is a cosmos of infinitely small ones; and in this complex world, the well-being of the whole depends entirely on the sum of well-being enjoyed by each of the least microscopic particles of organized matter. A whole revolution is thus produced in the philosophy of life.”

“Most of us spend our lives avoiding the thought of death. Instead, the inevitability of death should be continually on our minds. Understanding the shortness of life fills us with a sense of purpose and urgency to realize our goals. Training ourselves to confront and accept this reality makes it easier to manage the inevitable setbacks, separations, and crises in life. It gives us a sense of proportion, of what really matters in this brief existence of ours. Most people continually look for ways to separate themselves from others and feel superior. Instead, we must see the mortality in everyone, how it equalizes and connects us all. By becoming deeply aware of our mortality, we intensify our experience of every aspect of life.”

“How different our lives are when we really know what is deeply important to us, and keeping that picture in mind, we manage ourselves each day to be and to do what really matters most.”

“You can't be complacent and accept the world just as it is. You have to imagine what the world might be and then push and work toward that future. Progress requires that you honestly confront the dark corners of our own past; extend rights and opportunities to more of your citizens; see the differences and diversity of this country as a strength, just as we in America try to see the diversity of our country as a strength and not a weakness. So you can choose the path to progress, but it requires making some important choices.”

“Philosophy can take us no further than enabling us to command a clear view of the concepts by means of which we think about the world, and, by so doing, to attain a firmer grasp of the way we represent the world in our thought. It is for this reason and in this sense that philosophy is about the world.”

“"What's the matter with this country is the matter with the lot of us individually— our sense of personality is a sense of outrage and we'll never get outside of it."But the hold of the country was that, she considered, it could be thought of in terms of oneself, so interpreted.”

“Along with the loss of the sense of self has gone a loss of our language for communicating deeply personal meanings to each other. This is one important side of the loneliness now experienced by people in the Western world.”

“How we treat our fellow creatures is only one more way in which each one of us, every day, writes our own epitaph—bearing into the world a message of light and life or just more darkness and death, adding to the world's joy or to its despair.”

“It is indeed a matter of great difficulty to discover, and effectually to distinguish, the true motions of particular bodies from the apparent; because the parts of that immovable space, in which those motions are performed, do by no means come under the observation of our senses. Yet the thing is not altogether desperate; for we have some arguments to guide us, partly from the apparent motions, which are the differences of the true motions; partly from the forces, which are the causes and effects of the true motions.”
