„Earnestness means willingness to live with energy, though energy bring pain.“
— William James, Context: One mode of emotional excitability is exceedingly important in the composition of the energetic character, from its peculiarly destructive power over inhibitions. I mean what in its lower form is mere irascibility, susceptibility to wrath, the fighting temper; and what in subtler ways manifests itself as impatience, grimness, earnestness, severity of character. Earnestness means willingness to live with energy, though energy bring pain. The pain may be pain to other people or pain to one's self — it makes little difference; for when the strenuous mood is on one, the aim is to break something, no matter whose or what. Nothing annihilates an inhibition as irresistibly as anger does it; for, as Moltke says of war, destruction pure and simple is its essence.

Context: The observing mind is not a physical system, it cannot interact with any physical system. And it might be better to reserve the term "subject" for the observing mind. … For the subject, if anything, is the thing that senses and thinks. Sensations and thoughts do not belong to the "world of energy."
„It turns out that the energy of a gravitational field—any gravitational field—is negative. During inflation, as the universe gets bigger and bigger and more and more matter is created, the total energy of matter goes upward by an enormous amount. Meanwhile, however, the energy of gravity becomes more and more negative. The negative gravitational energy cancels the energy in matter, so the total energy of the system remains whatever it was when inflation started—presumably something very small.... This capability for producing matter in the universe is one crucial difference between the inflationary model and the previous model.“

„If you want to find the secrets of the universe, think in terms of energy, frequency and vibration.“

„The power of thought is the light of knowledge, the power of will is the energy of character, the power of heart is love. Reason, love and power of will are perfections of man.“

„Cautious, careful people, always casting about to preserve their reputation and social standing, never can bring about a reform. Those who are really in earnest must be willing to be anything or nothing in the world's estimation.“

„Choking with dry tears and raging, raging, raging at the absolute indifference of nature and the world to the death of love, the death of hope and the death of beauty, I remember sitting on the end of my bed, collecting these pills and capsules together and wondering why, why when I felt I had so much to offer, so much love, such outpourings of love and energy to spend on the world, I was incapable of being offered love, giving it or summoning the energy with which I knew I could transform myself and everything around me.“
— Stephen Fry, Moab Is My Washpot
„We simply must balance our demand for energy with our rapidly shrinking resources. By acting now we can control our future instead of letting the future control us.“

„Attention is not a mysterious concentration of psychic energy; it is simply an allotment of analyzing mechanisms to a limited region of the field. To pay attention to a figure is to make certain analyses of, or certain constructions in, the corresponding part of the icon.“
