No fairer destiny could be allotted to any physical theory, than that it should of itself point out the way to the introduction of a more comprehensive theory, in which it lives on as a limiting case.

Albert Einstein

We are doing everything possible to give labor this new status of social duty and to link it on the one side with the development of a technology which will create the conditions for greater freedom, and on the other side with voluntary work based on a Marxist appreciation of the fact that man truly reaches a full human condition when he produces without being driven by the physical need to sell his labor as a commodity.

When someone admits one and rejects another which is equally in accordance with the appearances, it is clear that he has quitted all physical explanation and descended into myth.

The morality of an action depends on the motive from which we act. If I fling half a crown to a beggar with intention to break his head and he picks it up and buy victuals with it, the physical effect is good. But with respect to me the action is very wrong.

Physically you are a human being, but mentally you are incomplete. Given that we have this physical human form, we must safeguard our mental capacity for judgment. For that, we cannot take out insurance; the insurance company is within: self-discipline, self-awareness, and a clear realization of the disadvantages of anger and the positive effects of kindness.

Tenzin Gyatso, 14th Dalai Lama

He who knows others is wise;
He who knows himself is enlightened.
He who conquers others has physical strength.
He who conquers himself is strong.

We are so anxious to achieve some particular end that we never pay attention to the psycho-physical means whereby that end is to be gained. So far as we are concerned, any old means is good enough. But the nature of the universe is such that ends can never justify the means. On the contrary, the means always determine the end.

Now the standard cure for one who is sunk is to consider those in actual destitution or physical suffering

F. Scott Fitzgerald

As a single footstep will not make a path on the earth, so a single thought will not make a pathway in the mind. To make a deep physical path, we walk again and again. To make a deep mental path, we must think over and over the kind of thoughts we wish to dominate our lives.

Henry David Thoreau

A man may have strong humanitarian and democratic principles, but if he happens to have been brought up as a bath-taking, shirt-changing lover of fresh air, he will have to overcome certain physical repugnance before he can bring himself to put those principles into practice.

You and I are different races. We have between us a broader difference than exists between almost any other races. Whether it be right or wrong, I need not discuss; but this physical difference is a great disadvantage to us both, as I think. Your race suffer very greatly, many of them by living amongst us, while ours suffer from your presence. In a word, we suffer on each side. If this is admitted, it affords a reason at least why we should be separated.

Abraham Lincoln

In one variant, "When one of you sees someone who has been given more bounty in respect of wealth or physical strength, he should then look at someone who has less than him."

But physical fitness is as vital to the activities of peace as to those of war, especially when our success in those activities may well determine the future of freedom in the years to come. We face in the Soviet Union a powerful and implacable adversary determined to show the world that only the Communist system possesses the vigor and determination necessary to satisfy awakening aspirations for progress and the elimination of poverty and want. To meet the challenge of this enemy will require determination and will and effort on the part of all Americans. Only if our citizens are physically fit will they be fully capable of such an effort.

John F. Kennedy

A science fiction story is just an attempt to solve a problem that exists in the world, sometimes a moral problem, sometimes a physical or social or theological problem.

And so, supposing that light impinging on a refracting or reflecting ethereal superficies puts it into a vibrating motion, that physical superficies being by the perpetual applause of rays always kept in a vibrating motion, and the ether therein continually expanded and compressed by turns, if a ray of light impinge on it when it is much compressed, I suppose it is then too dense and stiff to let the ray through, and so reflects it; but the rays that impinge on it at other times, when it is either expanded by the interval between two vibrations or not too much compressed and condensed, go through and are refracted.

Almost all the moral good which is left among us is the apparent effect of physical evil.

Physics is mathematical not because we know so much about the physical world, but because we know so little: it is only its mathematical properties that we can discover.

Bertrand Russell

The truth is that cowardice itself is violence of a subtle type and therefore dangerous and far more difficult to eradicate than the habit of physical violence.

A certain degree of physical harmony and comfort is necessary, but above a certain level it becomes a hindrance instead of a help. Therefore the ideal of creating an unlimited number of wants and satisfying them seems to be a delusion and a snare.

Natasha and I said more than once that one may arrive at such a physical condition that it would be better to cut short one's own life or, more correctly, the too slow process of dying … But whatever may be the circumstances of my death I shall die with unshaken faith in the communist future. This faith in man and in his future gives me even now such power of resistance as cannot be given by any religion.

As long as the mind is enslaved, the body can never be free. Psychological freedom, a firm sense of self-esteem, is the most powerful weapon against the long night of physical slavery.

Martin Luther King, Jr.

Let pessimism once take hold of the mind, and life is all topsy-turvy, all vanity and vexation of spirit. There is no cure for individual or social disorder, except in forgetfulness and annihilation. "Let us eat, drink and be merry," says the pessimist, "for tomorrow we die." If I regarded my life from the point of view of the pessimist, I should be undone. I should seek in vain for the light that does not visit my eyes and the music that does not ring in my ears. I should beg night and day and never be satisfied. I should sit apart in awful solitude, a prey to fear and despair. But since I consider it a duty to myself and to others to be happy, I escape a misery worse than any physical deprivation.

The spirit is the true self, not that physical figure which can be pointed out by your finger.

The greatest disease in the West today is not TB or leprosy; it is being unwanted, unloved, and uncared for. We can cure physical diseases with medicine, but the only cure for loneliness, despair, and hopelessness is love.

A physical theory is not an explanation. It is a system of mathematical propositions, deduced from a small number of principles, which aim... to represent as simply, as completely, and as exactly as possible a group of experimental laws.

Arthur Conan Doyle
