«If God creates a world of particles and waves, dancing in obedience to mathematical and physical laws, who are we to say that he cannot make use of those laws to cover the surface of a small planet with living creatures?»

«The future of humanity is uncertain, even in the most prosperous countries, and the quality of life deteriorates; and yet I believe that what is being discovered about the infinitely large and infinitely small is sufficient to absolve this end of the century and millennium. What a very few are acquiring in knowledge of the physical world will perhaps cause this period not to be judged as a pure return of barbarism.»

«The physical world, including our bodies, is a response of the observer. We create our bodies as we create the experience of our world.»

«Total physical and mental inertia are highly agreeable, much more so than we allow ourselves to imagine. A beach not only permits such inertia but enforces it, thus neatly eliminating all problems of guilt. It is now the only place in our overly active world that does.»

«Physical pleasure is a sensual experience no different from pure seeing or the pure sensation with which a fine fruit fills the tongue; it is a great unending experience, which is given us, a knowing of the world, the fullness and the glory of all knowing. And not our acceptance of it is bad; the bad thing is that most people misuse and squander this experience and apply it as a stimulant at the tired spots of their lives and as distraction instead of a rallying toward exalted moments.»

«I cannot conceive of a God who rewards and punishes his creatures, or has a will of the kind that we experience in ourselves. Neither can I nor would I want to conceive of an individual that survives his physical death; let feeble souls, from fear or absurd egoism, cherish such thoughts. I am satisfied with the mystery of the eternity of life and with the awareness and a glimpse of the marvelous structure of the existing world, together with the devoted striving to comprehend a portion, be it ever so tiny, of the Reason that manifests itself in nature.»

«Physical concepts are free creations of the human mind, and are not, however it may seem, uniquely determined by the external world.»

«It is curious - curious that physical courage should be so common in the world, and moral courage so rare»

«Old habit of mind is one of the toughest things to get away from in the world. It transmits itself like physical form and feature . . .»

«The components of anxiety, stress, fear, and anger do not exist independently of you in the world. They simply do not exist in the physical world, even though we talk about them as if they do.»
