The feeling of self-assurance derived from physical achievement always transfers itself to the mental sphere.
Stefan Zweig
The mental never influences the physical. It is always the physical that modifies the mental, and when we think that the mind is diseased, it is always an illusion.
Claude Bernard
In the new science of the twenty-first century, not physical force but spiritual force will lead the way. Mental and spiritual gifts will be more in demand than gifts of a physical nature. Extrasensory perception will take precedence over sensory perception. And in this sphere woman will again predominate. She who was revered and worshiped by early man because of her power to see the unseen will once again be the pivot—not as sex but as divine woman—about whom the next civilization will, as of old, revolve.
Elizabeth Gould Davis
Of patience there is this to be said. To be patient is to suffer. By their fruits men know one another, but by their sufferings they are what they are. And suffering is not merely the endurance of physical or mental anguish, but of joy also. A rabbit caught in a trap may be supposed to suffer physical anguish : but it suffers nothing else. The man crucified may be supposed to suffer physical & mental anguish, but he suffers also intense happiness and joy. The industrialist workman is often simply as a rabbit in a trap ; the artist is often as a man nailed to a cross. In patience souls are possessed. No lower view of the matter will suffice.
Eric Gill
There is a physical neurobiological substrate to all human knowledge, including thoughts, memories, perceptions and emotions. To this end, mental states and thought processes are physical.
Nayef Al-Rodan
The law of habit exhibits a striking contrast to all physical laws in the character of its commands. A physical law is absolute. What it requires is an exact relation. Thus, a physical force introduces into a motion a component motion to be combined with the rest by the parallelogram of forces; but the component motion must actually take place exactly as required by the law of force. On the other hand, no exact conformity is required by the mental law. Nay, exact conformity would be in downright conflict with the law ; since it would instantly crystallise thought and prevent all further formation of habit. The law of mind only makes a given feeling more likely to arise. It thus resembles the "non-conservative" forces of physics, such as viscosity and the like, which are due to statistical uniformities in the chance encounters of trillions of molecules.
