“From an ethical point of view the price difference is grotesque and from a political point of view, it represents a lack of respect, as though a sick Brazilian is inferior.”

“Now the kind of philosophy under which we proceed in the whole and in the part is moral philosophy or ethics; because the whole was undertaken not for speculation but for practice.”
Genus vero philosophie, sub quo hic in toto et parte proceditur, est morale negotium, sive ethica; quia non ad speculandum, sed ad opus inventum est totum et pars.

Dante Alighieri (1265–1321) Italian poet

“Life is not the means for the achievement of an esthetic ideal of perfection; on the contrary, the work is an ethical symbol of life.”

Thomas Mann (1875–1955) German novelist, and 1929 Nobel Prize laureate

Reflections of a Non-Political Man [Betrachtungen eines Unpolitischen] (1918)
Context: The important thing for me, then, is not the "work," but my life. Life is not the means for the achievement of an esthetic ideal of perfection; on the contrary, the work is an ethical symbol of life.

“Make ethical choices in what we buy, do, and watch. In a consumer-driven society our individual choices, used collectively for the good of animals and nature, can change the world faster than laws.”

The Quotable Sir John

“The very fact that religions are not content to stand on their own feet, but insist on crippling or warping the flexible minds of children in their favour, forms a sufficient proof that there is no truth in them. If there were any truth in religion, it would be even more acceptable to a mature mind than to an infant mind—yet no mature mind ever accepts religion unless it has been crippled in infancy. … The whole basis of religion is a symbolic emotionalism which modern knowledge has rendered meaningless & even unhealthy. Today we know that the cosmos is simply a flux of purposeless rearrangement amidst which man is a wholly negligible incident or accident. There is no reason why it should be otherwise, or why we should wish it otherwise. All the florid romancing about man's "dignity", "immortality", &c. &c. is simply egotistical delusions plus primitive ignorance. So, too, are the infantile concepts of "sin" or cosmic "right" & "wrong". Actually, organic life on our planet is simply a momentary spark of no importance or meaning whatsoever. Man matters to nobody except himself. Nor are his "noble" imaginative concepts any proof of the objective reality of the things they visualise. Psychologists understand how these concepts are built up out of fragments of experience, instinct, & misapprehension. Man is essentially a machine of a very complex sort, as La Mettrie recognised nearly 2 centuries ago. He arises through certain typical chemical & physical reactions, & his members gradually break down into their constituent parts & vanish from existence. The idea of personal "immortality" is merely the dream of a child or savage. However, there is nothing anti-ethical or anti-social in such a realistic view of things. Although meaning nothing in the cosmos as a whole, mankind obviously means a good deal to itself. Therefore it must be regulated by customs which shall ensure, for its own benefit, the full development of its various accidental potentialities. It has a fortuitous jumble of reactions, some of which it instinctively seeks to heighten & prolong, & some of which it instinctively seeks to shorten or lessen. Also, we see that certain courses of action tend to increase its radius of comprehension & degree of specialised organisation (things usually promoting the wished-for reactions, & in general removing the species from a clod-like, unorganised state), while other courses of action tend to exert an opposite effect. Now since man means nothing to the cosmos, it is plan that his only logical goal (a goal whose sole reference is to himself) is simply the achievement of a reasonable equilibrium which shall enhance his likelihood of experiencing the sort of reactions he wishes, & which shall help along his natural impulse to increase his differentiation from unorganised force & matter. This goal can be reached only through teaching individual men how best to keep out of each other's way, & how best to reconcile the various conflicting instincts which a haphazard cosmic drift has placed within the breast of the same person. Here, then, is a practical & imperative system of ethics, resting on the firmest possible foundation & being essentially that taught by Epicurus & Lucretius. It has no need of supernatualism, & indeed has nothing to do with it.”

H.P. Lovecraft (1890–1937) American author

“Some sixty years ago, Pope Pius XII, in a memorable address to anaesthesiologists and intensive care specialists, stated that there is no obligation to have recourse in all circumstances to every possible remedy and that, in some specific cases, it is permissible to refrain from their use… The specific element of this criterion is that it considers “the result that can be expected, taking into account the state of the sick person and his or her physical and moral resources”. It thus makes possible a decision that is morally qualified as withdrawal of “overzealous treatment”.
Such a decision responsibly acknowledges the limitations of our mortality, once it becomes clear that opposition to it is futile. “Here one does not will to cause death; one’s inability to impede it is merely accepted” (Catechism of the Catholic Church, No. 2278). This difference of perspective restores humanity to the accompaniment of the dying, while not attempting to justify the suppression of the living. It is clear that not adopting, or else suspending, disproportionate measures, means avoiding overzealous treatment; from an ethical standpoint, it is completely different from euthanasia, which is always wrong, in that the intent of euthanasia is to end life and cause death.
The anguish associated with conditions that bring us to the threshold of human mortality, and the difficulty of the decision we have to make, may tempt us to step back from the patient. Yet this is where, more than anything else, we are called to show love and closeness, recognizing the limit that we all share and showing our solidarity.
Let each of us give love in his or her own way—as a father, a mother, a son, a daughter, a brother or sister, a doctor or a nurse. But give it!”

“No science of any kind can be divorced from ethical considerations… Science is a human learning process which arises in certain subcultures in human society and not in others, and a subculture as we seen is a group of people defined by acceptance of certain common values, that is, an ethic which permits extensive communication between them.”

“I learnt to see philosophical systems in the context of the social milieu which produced them. I therefore learnt to look for social contention in philosophical systems. It is of course possible to see the history of philosophy in diverse ways, each way of seeing it being in fact an illumination of the type of problem dealt with in this branch of human thought. It is possible, for instance, to look upon philosophy as a series of abstract systems. When philosophy is so seen, even moral philosophers, with regrettable coyness, say that their preoccupation has nothing to do with life. They say that their concern is not to name moral principles or to improve anybody's character, but narrowly to elucidate the meaning of terms used in ethical discourse, and to determine the status of moral principles and ru1es, as regards the obligation which they impose upon us. When philosophy is regarded in the light of a series of abstract systems, it can be said to concern itself with two fundamental questions: first, the question 'what there is'; second, the question how 'what there is' may be explained. The answer to the first question has a number of aspects. It lays down a minimum number of general under which every item in the world can and must be brought. It does this without naming the items themselves, without furnishing us with an inventory, a roll-call of the items, the objects in the world. It specifies, not particu1ar objects, but the basic types of object. The answer further implies a certain reductionism; for in naming only a few basic types as exhausting all objects in the world, it brings object directly under one of the basic types.”

“The great fault of all ethics hitherto has been that they believed themselves to have to deal only with the relations of man to man. In reality, however, the question is what is his attitude to the world and all life that comes within his reach.”

Albert Schweitzer (1875–1965) French-German physician, theologian, musician and philosopher

Source: Out of My Life and Thought : An Autobiography (1933), Ch. 13, p. 188
Context: The great fault of all ethics hitherto has been that they believed themselves to have to deal only with the relations of man to man. In reality, however, the question is what is his attitude to the world and all life that comes within his reach. A man is ethical only when life, as such, is sacred to him, and that of plants and animals as that of his fellow men, and when he devotes himself helpfully to all life that is in need of help. Only the universal ethic of the feeling of responsibility in an ever-widening sphere for all that lives — only that ethic can be founded in thought. … The ethic of Reverence for Life, therefore, comprehends within itself everything that can be described as love, devotion, and sympathy whether in suffering, joy, or effort.

“For in world- and life-affirmation and in ethics I carry out the will of the universal will-to-live which reveals itself in me. I live my life in God, in the mysterious divine personality which I do not know as such in the world, but only experience as mysterious Will within myself.
Rational thinking which is free from assumptions ends therefore in mysticism.”

Albert Schweitzer (1875–1965) French-German physician, theologian, musician and philosopher

Kulturphilosophie (1923), Vol. 2 : Civilization and Ethics
Context: Affirmation of the world, which means affirmation of the will-to-live that manifests itself around me, is only possible if I devote myself to other life. From an inner necessity, I exert myself in producing values and practising ethics in the world and on the world even though I do not understand the meaning of the world. For in world- and life-affirmation and in ethics I carry out the will of the universal will-to-live which reveals itself in me. I live my life in God, in the mysterious divine personality which I do not know as such in the world, but only experience as mysterious Will within myself.
Rational thinking which is free from assumptions ends therefore in mysticism. To relate oneself in the spirit of reverence for life to the multiform manifestations of the will-to-live which together constitute the world is ethical mysticism. All profound world-view is mysticism, the essence of which is just this: that out of my unsophisticated and naïve existence in the world there comes, as a result of thought about self and the world, spiritual self-devotion to the mysterious infinite Will which is continuously manifested in the universe.

“The agitator who preaches hatred and practices slander and untruthfulness, and the visionary who promises perfection and accomplishes only destruction, are the worst enemies of reform; and the man of great wealth who accumulates and uses his wealth without regard to ethical standards, who profits by and breeds corruption, and robs and swindles others, is the very worst enemy of property, the very worst enemy of conservatism, the very worst enemy of those “business interests” that only too often regard him with mean admiration and heatedly endeavor to shield him from the consequences of his iniquity.”

Theodore Roosevelt (1858–1919) American politician, 26th president of the United States

1910s, The Progressives, Past and Present (1910)
Context: Violent excess is sure to provoke violent reaction; and the worst possible policy for our country would be one of violent oscillation between reckless upsetting of property rights, and unscrupulous greed manifested under pretense of protecting those rights. The agitator who preaches hatred and practices slander and untruthfulness, and the visionary who promises perfection and accomplishes only destruction, are the worst enemies of reform; and the man of great wealth who accumulates and uses his wealth without regard to ethical standards, who profits by and breeds corruption, and robs and swindles others, is the very worst enemy of property, the very worst enemy of conservatism, the very worst enemy of those “business interests” that only too often regard him with mean admiration and heatedly endeavor to shield him from the consequences of his iniquity.

“Ethics is in its unqualified form extended responsibility to everything that has life.”

Albert Schweitzer (1875–1965) French-German physician, theologian, musician and philosopher

Kulturphilosophie (1923), Vol. 2 : Civilization and Ethics
Context: It is the fate of every truth to be an object of ridicule when it is first acclaimed. It was once considered foolish to suppose that black men were really human beings and ought to be treated as such. What was once foolish has now become a recognized truth. Today it is considered as exaggeration to proclaim constant respect for every form of life as being the serious demand of a rational ethic. But the time is coming when people will be amazed that the human race existed so long before it recognized that thoughtless injury to life is incompatible with real ethics. Ethics is in its unqualified form extended responsibility to everything that has life.

Albert Schweitzer photo

“A man is really ethical only when he obeys the constraint laid on him to help all life which he is able to succor, and when he goes out of his way to avoid injuring anything living. He does not ask how far this or that life deserves sympathy as valuable in itself, nor how far it is capable of feeling. To him life as such is sacred. He shatters no ice crystal that sparkles in the sun, tears no leaf from its tree, breaks off no flower, and is careful not to crush any insect as he walks.”

Albert Schweitzer (1875–1965) French-German physician, theologian, musician and philosopher

He shatters no ice crystal that sparkles in the sun, tears no leaf from its tree, breaks off no flower, and is careful not to crush any insect as he walks. If he works by lamplight on a summer evening, he prefers to keep the window shut and to breathe stifling air, rather than to see insect after insect fall on his table with singed and sinking wings.
If he goes out in to the street after a rainstorm and sees a worm which has strayed there, he reflects that it will certainly dry up in the sunshine, if it does not quickly regain the damp soil into which it can creep, and so he helps it back from the deadly paving stones into the lush grass. Should he pass by an insect which has fallen into a pool, he spares the time to reach it a leaf or stalk on which it may clamber and save itself.

“Let me give you a definition of ethics: It is good to maintain and further life — it is bad to damage and destroy life. And this ethic, profound and universal, has the significance of a religion. It is religion.”

“What the activity of this disposition of ours means in the evolution of the world, we do not know. Nor can we regulate this activity from outside; we must leave entirely to each individual its shaping and its extension. From every point of view, then, world- and life-affirmation and ethics are non-rational, and we must have the courage to admit it.”

Albert Schweitzer (1875–1965) French-German physician, theologian, musician and philosopher

Kulturphilosophie (1923), Vol. 2 : Civilization and Ethics
Context: The restoration of our world-view can come only as a result of inexorably truth-loving and recklessly courageous thought. Such thinking alone is mature enough to learn by experience how the rational, when it thinks itself out to a conclusion, passes necessarily over into the non-rational. World- and life-affirmation and ethics are non-rational. They are not justified by any corresponding knowledge of the nature of the world, but are the disposition in which, through the inner compulsion of our will-to-live, we determine our relation to the world.

“The ethical ideas on which civilization rests have been wandering about the world, poverty-stricken and homeless.”

Albert Schweitzer (1875–1965) French-German physician, theologian, musician and philosopher

Source: Kulturphilosophie (1923), Vol. 1 : The Decay and the Restoration of Civilization, Ch. 1 How Philosophy is Responsible for the Collapse of Civilization
Context: The ethical ideas on which civilization rests have been wandering about the world, poverty-stricken and homeless. No theory of the universe has been advanced which can give them solid foundation; in fact not one has made its appearance which can claim for itself solidity and inner consistency. The age of philosophical dogmatism had come to an end, and after that nothing was recognized as truth except the science which described reality. Complete theories of the universe no longer appeared as fixed stars; they were regarded as resting on hypothesis, and ranked no higher than comets.

“Its first ethical precept is the identity of means used and aims sought. The ultimate end of all revolutionary social change is to establish the sanctity of human life, the dignity of man, the right of every human being to liberty and wellbeing.”

My Disillusionment in Russia (1923)
Context: Its first ethical precept is the identity of means used and aims sought. The ultimate end of all revolutionary social change is to establish the sanctity of human life, the dignity of man, the right of every human being to liberty and wellbeing. Unless this be the essential aim of revolution, violent social changes would have no justification. For external social alterations can be, and have been, accomplished by the normal processes of evolution. Revolution, on the contrary, signifies not mere external change, but internal, basic, fundamental change. That internal change of concepts and ideas, permeating ever-larger social strata, finally culminates in the violent upheaval known as revolution.

“Ethics in our Western world has hitherto been largely limited to the relations of man to man. But that is a limited ethics. We need a boundless ethics which will include the animals also.”

Albert Schweitzer (1875–1965) French-German physician, theologian, musician and philosopher

Kulturphilosophie (1923), Vol. 2 : Civilization and Ethics
Context: I must interpret the life about me as I interpret the life that is my own. My life is full of meaning to me. The life around me must be full of significance to itself. If I am to expect others to respect my life, then I must respect the other life I see, however strange it may be to mine. And not only other human life, but all kinds of life: life above mine, if there be such life; life below mine, as I know it to exist. Ethics in our Western world has hitherto been largely limited to the relations of man to man. But that is a limited ethics. We need a boundless ethics which will include the animals also.

“The theme is an attempt to trace the defects of society back to the defects of human nature. The moral is that the shape of a society must depend on the ethical nature of the individual and not on any political system however apparently logical or respectable.”

William Golding (1911–1993) British novelist, poet, playwright and Nobel Prize for Literature laureate

Responses in a publicity questionnaire on Lord of the Flies from the American publishers, as quoted in Who Rules?: Introduction to the Study of Politics (1971) by Dick W. Simpson, p. 16
Context: The theme is an attempt to trace the defects of society back to the defects of human nature. The moral is that the shape of a society must depend on the ethical nature of the individual and not on any political system however apparently logical or respectable. The whole book is symbolic in nature except the rescue in the end where adult life appears, dignified and capable, but in reality enmeshed in the same evil as the symbolic life of the children on the island. The officer, having interrupted a man-hunt, prepares to take the children off the island in a cruiser which will presently be hunting its enemy in the same implacable way. And who will rescue the adult and his cruiser?

“The ethic of reverence for life constrains all, in whatever walk of life they may find themselves, to busy themselves intimately with all the human and vital processes which are being played out around them, and to give themselves as men to the man who needs human help and sympathy. It does not allow the scholar to live for his science alone, even if he is very useful to the community in so doing. It does not permit the artist to exist only for his art, even if he gives inspiration to many by its means. It refuses to let the business man imagine that he fulfills all legitimate demands in the course of his business activities.”

It demands from all that they should sacrifice a portion of their own lives for others. In what way and in what measure this is his duty, this everyone must decide on the basis of the thoughts which arise in himself, and the circumstances which attend the course of his own life. The self-sacrifice of one may not be particularly in evidence. He carries it out simply by continuing his normal life. Another is called to some striking self-surrender which obliges him to set on one side all regard for his own progress. Let no one measure himself by his conclusions respecting someone else. The destiny of men has to fulfill itself in a thousand ways, so that goodness may be actualized. What every individual has to contribute remains his own secret. But we must all mutually share in the knowledge that our existence only attains its true value when we have experienced in ourselves the truth of the declaration: 'He who loses his life shall find it.

“To the man who is truly ethical all life is sacred, including that which from the human point of view seems lower in the scale. He makes distinctions only as each case comes before him, and under the pressure of necessity, as, for example, when it falls to him to decide which of two lives he must sacrifice in order to preserve the other.”

He makes distinctions only as each case comes before him, and under the pressure of necessity, as, for example, when it falls to him to decide which of two lives he must sacrifice in order to preserve the other. But all through this series of decisions he is conscious of acting on subjective grounds and arbitrarily, and knows that he bears the responsibility for the life which is sacrificed.

“We have grasped the mystery of the atom and rejected the Sermon on the Mount. The world has achieved brilliance without conscience. Ours is a world of nuclear giants and ethical infants. We know more about war than we know about peace, more about killing than we know about living.”

Omar Bradley (1893–1981) United States Army field commander during World War II

Armistice Day speech (11 November 1948), published in Omar Bradley's Collected Writings, Volume 1 (1967).
Context: We have men of science, too few men of God. We have grasped the mystery of the atom and rejected the Sermon on the Mount. The world has achieved brilliance without conscience. Ours is a world of nuclear giants and ethical infants. We know more about war than we know about peace, more about killing than we know about living. If we continue to develop our technology without wisdom or prudence, our servant may prove to be our executioner.

It is true that these rules neither are nor ought to be of eternal obligation, but do and must vary more or less from age to age, as the consciences of nations become more enlightened, and the exigences of political society undergo change. But the rules mostly were at their origin, and still are, an application of the maxims of honesty and humanity to the intercourse of states. They were introduced by the moral sentiments of mankind, or by their sense of the general interest, to mitigate the crimes and sufferings of a state of war, and to restrain governments and nations from unjust or dishonest conduct towards one another in time of peace. Since every country stands in numerous and various relations with the other countries of the world, and many, our own among the number, exercise actual authority over some of these, a knowledge of the established rules of international morality is essential to the duty of every nation, and therefore of every person in it who helps to make up the nation, and whose voice and feeling form a part of what is called public opinion. Let not any one pacify his conscience by the delusion that he can do no harm if he takes no part, and forms no opinion. Bad men need nothing more to compass their ends, than that good men should look on and do nothing. He is not a good man who, without a protest, allows wrong to be committed in his name, and with the means which he helps to supply, because he will not trouble himself to use his mind on the subject. It depends on the habit of attending to and looking into public transactions, and on the degree of information and solid judgment respecting them that exists in the community, whether the conduct of the nation as a nation, both within itself and towards others, shall be selfish, corrupt, and tyrannical, or rational and enlightened, just and noble.

“Morality must be the heart of our existence, if it is to be what it wants to be for us. ... The highest form of philosophy is ethics. Thus all philosophy begins with “I am.””

Novalis (1772–1801) German poet and writer

The highest statement of cognition must be an expression of that fact which is the means and ground for all cognition, namely, the goal of the I.

“Accepting evolution does not force us to jettison our morals and ethics, and rejecting evolution does not ensure their constancy.”

“Saying someone is religious is heard in most of America as a compliment, a reassuring affirmation that someone will be moral, ethical, and after a few glasses of wine, a freak in the bedroom.”

Bill Maher (1956) American stand-up comedian

“Ethical behavior is doing the right thing when no one else is watching — even when doing the wrong thing is legal.”

Aldo Leopold (1887–1948) American writer and scientist

Presumably a paraphrase of "A peculiar virtue in wildlife ethics is that the hunter ordinarily has no gallery to applaud or disapprove of his conduct" or of "Hunting for sport is an improvement ..." above.
Unlikely to be by Leopold, who knew that ethics involves not only doing the right thing, but also determining the right thing in the face of competing desirable criteria.
