Physical science is like simple addition: it is either infallible or it is false.
G. K. Chesterton

I cannot conceive of anything after my physical death—perhaps it will end it all. The knowledge that I am now on this earth and a mysterious part of eternity is enough for me. My death will be an easy one, too, for since early youth I have always detached myself from family, friends, and surroundings. And should I live on, I have no fear of the next life. Whatever good I did helped to free me from myself. What a miserable creature man would be if he were good not for the sake of being good, but because religion told him that he would get a reward after this life, and that if he weren't good he'd be punished.

We want to express physical laws in such a way that it shall be obvious when we are expressing the same law by reference to two different systems of co-ordinates, so that we shall not be misled into supposing we have different laws when we have one law in different words. This is accomplished by the method of tensors.

I was almost driven to madness in considering and calculating this matter. I could not find out why the planet would rather go on an elliptical orbit. Oh, ridiculous me! As the liberation in the diameter could not also be the way to the ellipse. So this notion brought me up short, that the ellipse exists because of the liberation. With reasoning derived from physical principles, agreeing with experience, there is no figure left for the orbit of the planet but a perfect ellipse.

Doubtless, we are as slow to conceive of Paradise as of Heaven, of a perfect natural as of a perfect spiritual world. We see how past ages have loitered and erred. "Is perhaps our generation free from irrationality and error? Have we perhaps reached now the summit of human wisdom, and need no more to look out for mental or physical improvement?" Undoubtedly, we are never so visionary as to be prepared for what the next hour may bring forth.

Man, as a physical being, is like other bodies governed by invariable laws.

If a person's basic state of mind is serene and calm, then it is possible for this inner peace to overwhelm a painful physical experience. On the other hand, if someone is suffering from depression, anxiety, or any form of emotional distress, then even if he or she happens to be enjoying physical comforts, he will not really be able to experience the happiness that these could bring.
Tenzin Gyatso, 14th Dalai Lama

The sole purpose of physical theory is to provide a representation and classification of experimental laws; the only test permitting us to judge a physical theory and pronounce it good or bad is the comparison between the consequences of this theory and the experimental laws it has to represent and classify.

Our growing softness, our increasing lack of physical fitness, is a menace to our security.

Physics is an attempt conceptually to grasp reality as something that is considered to be independent of its being observed. In this sense one speaks of physical reality.

Perhaps it is the lowest of the qualities of an orator, but it is, on so many occasions, of chief importance,--a certain robust and radiant physical health; or--shall I say?--great volumes of animal heat.
Ralph Waldo Emerson

Masculine exhalations are, as a rule, stronger, more vivid, more widely differentiated than those of women. In the odor of young men there is something elemental, as of fire, storm, and salt sea. It pulsates with buoyancy and desire. It suggests all the things strong and beautiful and joyous and gives me a sense of physical happiness.

It seems to be unfortunately true that the epidemic of world lawlessness is spreading. When an epidemic of physical disease starts to spread, the community approves and joins in a quarantine of the patients in order to protect the health of the community against the spread of the disease.

If in all ideology men and their circumstances appear upside-down as in a camera obscura, this phenomenon arises just as much from their historical life-process as the inversion of objects on the retina does from the physical life-process.

The truth has no need to be uttered to be made apparent, and... one may perhaps gather it with more certainty, without waiting for words and without even taking any account of them, from countless outward signs, even from certain invisible phenomena, analogous in the sphere of human character to what atmospheric changes are in the physical world.

Although I'm regarded as a dangerous radical by particle physicists for proposing that there may be loss of quantum coherence, I'm definitely a conservative compared to Roger. I take the positivist viewpoint that a physical theory is just a mathematical model and that it is meaningless to ask whether it corresponds to reality. All that one can ask is that its predictions should be in agreement with observation. I think Roger [Penrose] is a Platonist at heart but he must answer for himself.

How is it possible that the poorer classes can remain healthy and have a reasonable expectation of life under such conditions? What can one expect but that they should suffer from continual outbreaks of epidemics and an excessively low expectation of life? The physical condition of the workers shows a progressive deterioration.

The workmen's revolution, with the terrors of destruction and murder, not only threatens us, but we have already been living upon its verge during the last thirty years, and it is only by various cunning devices that we have been postponing the crisis... The hatred and contempt of the oppressed people are increasing, and the physical and moral strength of the richer classes are decreasing: the deceit which supports all this is wearing out, and the rich classes have nothing wherewith to comfort themselves.
Leo Tolstoy

Some revolutions are inevitable. There are moral eruptions, just as the outbreak of volcanoes are physical eruptions. When the chemical combinations which produce them are complete, the volcanic eruptions burst forth, just as revolutions do when the moral factors are in the right state. In order to foresee them the trend of ideas must be understandingly observed.

This knowledge, the knowledge that the physical well-being of the citizen is an important foundation for the vigor and vitality of all the activities of the nation, is as old as Western civilization itself.

In this sense, physical fitness is the basis of all the activities of our society. And if our bodies grow soft and inactive, if we fail to encourage physical development and prowess, we will undermine our capacity for thought, for work and for the use of those skills vital to an expanding and complex America. Thus the physical fitness of our citizens is a vital prerequisite to America's realization of its full potential as a nation, and to the opportunity of each individual citizen to make full and fruitful use of his capacities.

Of course Mahatma Gandhi you might say did not have so much physical vigor but he certainly seemed to have extraordinary resistance, which perhaps is rather different from physical vigor.
