"Axiom 8. That the importance of any action is measured by the degree of pleasure or pain that it causes or prevents."
"In order to admire the goodness of God with the greatest force, we should endeavour to reach in imagination the improved state of the world, which it seems probable will be effected in the course of time. What may not be expected from the genius of man, which appears to gain fresh powers from every new idea that he gains from his fellows, and fresh means from all the inventions which the united efforts of the whole species bring forth? It is the extent of combination which chiefly raises man above brutes; and to combination are we to look to mature the views of Providence in forming society, and in regulating the affairs of life. Then will every animal within the reach of man feel the effects of his power, by his increase of happiness instead of his misery, and then only may man boast of his being lord of the creation, for which he will be fitted."
"Suppose...we reflect on the building of London Bridge, we cannot then help admiring the genius and assiduity of man. But could all the torture and destruction that this has caused to the poor horses, who drew the stones and cleared the rubbish, be brought to light, what an emblem of crime would this beautiful bridge exhibit; many years’ labour has it cost; many teams have been constantly at work, and the extreme severity of the labour imposed on them was almost at any time to be seen. Now, if all the strainings, the lashes, the blows, and the wrenchings with all the bits, had been kept account of, how immense would be the list..."
"[E]very animal has more right to the use of its own body than others have to use it."
"[H]owever the state of man may be above that of other animals, if the superiority be owing to his being differently situated, we must not dazzle ourselves by gazing on the brilliancy of the situation, but learn how to estimate their true qualities only; though the situation gives the one the powers to act, and denies it to the other."
"She wrote a book in 1964, Animal Machines, which did for animals what Rachel Carson's Silent Spring did for the environment."
"Every animal possesses something which distinguishes it from all other animals; and this is what I understand by personal identity, or rather the identical self. This in every animal is perfectly distinct and indivisible, since the only knowledge we have of it is when it is entire; and divisibility of this is what we cannot conceive: but if indivisible, it must also be indestructible, and must always have existed. It is not possessed of any kind of consciousness: but no consciousness can, it appears, exist without it; as life itself seems to be composed of personal identity, and other essentials of the mind or body, and that it is the combination which produces consciousness."
"It has been generally, but not always, the custom of naturalists to degrade the powers of dumb animals into mere instinct, and not to allow them reason; and on the other hand to elevate the qualities of man, by entirely disavowing the power of instinct in man, giving him the use of reason alone. It appears to me, that there is such a quality as instinct; by which I understand a desire to do any thing without knowing why, or without having the object in view which it is to reach. I am of opinion that both reason and instinct act in man and also in brutes; and I will even grant that the proportion of reason to instinct is greater in man than in other animals; but that the latter possess a great portion of reason would it seems be absurd to dispute."
"Therefore it is plain that no particular thing can be made by a machine at all; neither an atom, or matter, which is the only identity of matter; nor the soul, which is the only identity of a person (and this applies also to every other animal or vegetable, as every thing, if it feels, must, it appears, have an identical self or soul, similar to that of any other being). No feeling can, it appears, be without reference to some self or soul)"
"Things are not going well for me. My chef at the Charité strongly disapproves of women students and took this means of showing it. About a hundred men (no women except myself) went round the wards today, and when we were all assembled before him to have our names written down, he called and named all the students except me, and then closed the book. I stood forward upon this, and said quietly, "Et moi aussi, monsieur." [And me, Sir.] He turned on me sharply, and cried, "Vous, vous n'êtes ni homme ni femme; je ne veux pas inscrire vôtre nom." [You, you are neither man nor woman; I don't want to write your name.] I stood silent in the midst of a dead silence."
"How many times, for instance, have we not heard people speak with all the authority of conviction about the "canine teeth" and "simple stomach" of man, as certain evidence of his natural adaptation for a flesh diet! At least we have demonstrated one fact; that if such arguments are valid, they apply with even greater force to the anthropoid apes—whose "canine" teeth are much longer and more powerful than those of man … And yet, with the solitary exception of man, there is not one of these last which does not in a natural condition absolutely refuse to feed on flesh! M. Pouchet observes that all the details of the digestive apparatus in man, as well as his dentition, constitute "so many proofs of his frugivorous origin"—an opinion shared by Professor Owen, who remarks that the anthropoids and all the quadrumana derive their alimentation from fruits, grains, and other succulent and nutritive vegetable substances, and that the strict analogy which exists between the structure of these animals and that of man clearly demonstrates his frugivorous nature. This is also the view taken by Cuvier, Linnæus, Professor Lawrence, Charles Bell, Gassendi, Flourens, and a great number of other eminent writers."
"No man who aims at making his life an harmonious whole, pure, complete, and harmless to others, can endure to gratify an appetite at the cost of the daily suffering and bloodshed of his inferiors in degree, and of the moral degradation of his own kind. I know not which strikes me most forcibly in the ethics of this question the injustice, the cruelty, or the nastiness of flesh-eating. The injustice is to the butchers, the cruelty is to the animals, the nastiness concerns the consumer. With regard to this last in particular, I greatly wonder what persons of refinement—aye, even of decency—do not feel insulted on being offered, as a matter of course, portions of corpses as food! Such comestibles might possibly be tolerated during sieges, or times of other privation of proper viands in exceptional circumstances, but in the midst of a civilised community able to command a profusion of sound and delicious foods, it ought to be deemed an affront to set dead flesh before a guest."
"It has been well said … that there are steps on the way to the summit of Dietetic Reform, and, if only one step be taken, yet that single step will be not without importance and without influence in the world. The step, which leaves for ever behind it the barbarism of slaughtering our fellow-beings, the Mammals and Birds, is, it is superfluous to add, the most important and most influential of all."
"[T]hroughout history there are records of individuals who have provided answers to these puerile attempts at defending flesh eating. And those blokes who call vegetarianism faddish just aren’t aware of the history of ethical vegetarianism! People have always challenged the Regime of Blood!"
"Long before this, when reading that excellent book, The Ethics of Diet, I had wished to visit a slaughter-house, in order to see with my own eyes the reality of the question raised when vegetarianism is discussed. … The precise reason why abstinence from animal food will be the first act of fasting and of a moral life is admirably explained in the book, The Ethics of Diet; and not by one man only, but by all mankind in the persons of its best representatives during all the conscious life of humanity."
"I saw among them, much merit - much patient suffering - wonderful endurance - industry - care and desire to be and to appear respectable. I saw also the oppression of the laws as well as of most of their employers, and that also in which in its immediate effect is even more intolerable, the contumely with which all who thought themselves above them treated them. I not only saw all this but I felt it also, and I resolved never to abandon the working people and I never will."
"It were once clearly understood, that it was not disreputable for married persons to avail themselves of such precautionary means as would, without being injurious to health, or destructive of female delicacy, prevent conception, a sufficient check might at once be given to the increase of population beyond the means of subsistence ; vice and misery, to a prodigious extent, might be removed from society, and the object of Mr. Malthus, Mr. Godwin, and of every philanthropic person, be promoted, by the increase of comfort, of intelligence, and of moral conduct, in the mass of the population."
"My desire for information was, however, too strong to be turned aside and often have I been sent away from a bookstall when the owner became offended at my standing reading, which I used to do until I was sent away... I used to borrow books from a man who kept a small shop... leaving a small sum as a deposit. At the age of twenty, Place had worked through the histories of Greece and Rome and some translated works of Greek and Roman writers."
"At the age of twenty, Place had worked through the histories of Greece and Rome and some translated works of Greek and Roman writers. When unemployed, and for many months practically starving, he read many volumes in history, politics, law and philosophy, Adam Smith and Locke, and especially Hume's Essays and Treatises."
"I taught myself decimals, equations, the square, cube, and biquadrate roots. I got some knowledge of logarithms, and some of algebra. I readily got through a small schoolbook of geometry; and having an odd volume, the first, of Williamson's ' Euclid,' I attacked it vigorously and perseveringly. Williamson's is by no means the best book on the subject, yet I am still of opinion that it is the best book I could have had for the purpose of teaching myself."
"I was sometimes brought to a standstill, and at times almost despaired of making further progress... I knew no one of whom I could ask a question or receive any kind of instruction, and the subject was therefore at times very painful."
"It may be supposed that I led a miserable life but I did not I was very far indeed from being miserable at this time when my wife came home at night, we had always something to talk about, we were pleased to see each other, our reliance on each other was great indeed, we were poor, but we were young, active cheerful and although my wife at times doubted that we would get on in the world, I had no such misgivings."
"I can imagine nothing except being a footman or common soldier as more degrading than being either a barber or a tailor."
"In judging who are the maximum sufferers politicians must, today, cast their eyes around the whole globe and take into account the sufferings of all races, religions and species."
"What we should be concerned about is the happiness of individuals. Applying rights may be a rough and ready rule of thumb for doing this, but painism would be a far more accurate approach. It might require more detailed research into the consequences of policies on individuals but that, in principle, could be done. Indeed, to base public policy upon scientific findings would be a considerable step forward."
"The implication of painism is that political policies should extend to individuals of all nations, races, and species on an 'equal pain equal treatment' basis."
"Just as nobody pursues happiness in order to find anything other than happiness, so nobody strives to reduce pain to reduce anything other than pain. Pain is always at the end of the track: it is the ultimate and essential badness. 'Painful' and 'bad' are synonymous in the mind of the child and, at a basic level, in all our minds."
"[W]hat, ultimately, should politics be aiming for? What is the underlying moral objective? … None of the traditional political ideals … provides a satisfactory moral basis for politics today."
"Are there then any moral foundations on which we can all agree, at least to some extent? I believe there are and that they are these: pain is bad, and so, causing unnecessary pain to others is wrong."
"Ethics, as a rational enterprise, will often conflict with other, more negative, aspects of our natures and help to curb our natural impulses to conquer, compete, and kill. By putting morality back into politics and basing our policies upon our compassion and upon the sufferings of all individuals, regardless of their superficial differences, we should be able to build a happier future."
"[The] habit of totalling pains and pleasures across individuals is one of the main errors in ethics today."
"[P]olitical policy should be based, not upon mere opinion, nor upon a set of knee jerk reflexes, but upon a scientific concern for the facts and an intelligent and open moral argument."
"Idealism itself can become dangerous. But going too far in the other direction, towards relativism, amoral expediency and opportunism, is equally perilous."
"A sound moral argument requires both factual and moral premises. Yet there has been little intelligent dialogue at either level. The mumbling of slogans must no longer suffice. We must demand more of our leaders …"
"We have an obligation to try to reduce the pains of others, wherever they are, and however the pains have been caused."
"Their experiences may be more simple than ours, but are they less intense? Perhaps a caterpillar’s primitive pain when squashed is greater than our more sophisticated sufferings."
"Perhaps there is too much talk of justice, equality and liberty in political philosophy, and not enough about suffering. It is suffering that matters morally …"
"[C]ertain moral imperatives are, rightly, considered to transcend national boundaries. What, after all, is so imperative about geography? Suffering is global."
"Differences in reaction to toxic substances vary considerably between species so that the value of these tests remains doubtful. Although thalidomide was extensively tested on animals in several countries, its terrible properties were not discovered. Conversely, penicillin, the greatest medical discovery of the century, was not extensively tested on animals before its miraculous therapeutic qualities were demonstrated in human patients. If it had been fully tested on animals its high toxicity for guinea pigs would have almost certainly prevented its clinical use."
"Sometimes captured from the great arboreal freedom of their jungle homes, monkeys are closely confined in cages only three or four feet square. … They can never sit or lie down on a flat, soft or yielding surface. Little wonder that by the time they are needed for the knife or the needle they are so crazed or inert that they are no longer representative examples of animal life. Psychologists who study the behaviour of thousands of such creatures annually, rarely make allowances for the fact that their pathetic subjects have been so deprived that they have become more like monsters than animals. Many people who have experienced close affectionate relationships with individuals of other species testify to the considerable potential for emotional and intellectual development that animals have. When properly cared for a pet dog or cat can develop great subtleties of behaviour that the laboratory animal never shows. Those who have been fortunate enough to closely observe unfrightened animals living in the wild are often struck by the complexity and richness of the life they lead. These positive pleasures the laboratory animal never knows; for him the same four white walls and the smell of disinfectant."
"Our first moral concern should always be with the individual who is the maximum sufferer."
"Misleading may be the claims that procedures [of animal testing] are carried out under anaesthesia. Restraining devices and paralysing drugs can today be so effective that an anaesthetic is often unnecessary from the purely practical point of view. The risk of giving a dose too large and thereby losing an expensive chimpanzee, for example, may often tempt a scientist or technician, inexperienced with sophisticated anaesthetic techniques, to give a dose too small, from which the animal quickly recovers — but not of course until after it has been strapped securely to the operating table."
"Since Darwin, scientists have agreed that there is no ‘magical’ essential difference between human and other animals, biologically-speaking. Why then do we make an almost total distinction morally? If all organisms are on one physical continuum, then we should also be on the same moral continuum. … The only arguments in favour of painful experiments on animals are: 1) that the advancement of knowledge justifies all evils – well does it? 2) that possible benefits for our own species justify mistreatment of other species – this may be a fairly strong argument when it applies to experiments where the chances of suffering are minimal and the probability of aiding applied medicine is great, but even so it is still just ‘speciesism’, and as such it is a selfish emotional argument rather than a reasoned one."
"Consciousness is of paramount importance to all of us. By definition it is the universe of our awareness. On the assumption that many other species are conscious or sentient I have suggested that our morality is based upon a concern for all sentients-which I have called sentientism, although I could equally have called it consciousism (but that is even more horrible as a word!). Pain and pleasure are the two great poles of consciousness, between which all sentients swing ... ."
"It is always wrong to cause pain to A merely in order to increase the pleasure of B."
"The 1960s revolutions against racism, sexism and classism nearly missed out the animals. This worried me. Ethics and politics at the time simply overlooked the nonhumans entirely. Everyone seemed to be just preoccupied with reducing the prejudices against humans. Hadn’t they heard of Darwin? I hated racism, sexism and classism, too, but why stop there? As a hospital scientist I believed that hundreds of other species of animals suffer fear, pain and distress much as I did. Something had to be done about it. We needed to draw the parallel between the plight of the other species and our own. One day in 1970, lying in my bath at the old Sunningwell Manor, near Oxford, it suddenly came to me: SPECIESISM!"
"… it is less imperatively my duty to give pleasure than it is to alleviate pain. If someone else is not actually suffering then it seems more acceptable to leave to them … the provision of their own pleasures."
"[When asked by presenter Lauren Booth: "Would a Muslim go against his Egyptian brother and open fire?"] It seems a bit unlikely that would happen during Ramadan, to put it mildly, and I suspect the hand of Israel in this whole process of destabilisation."
"Well, you have to ask the question why they're in prison in the first place and since the releases that took place after the hunger strike I met many of the brothers including the brother who has been speaking here when they came out of prison when I was in Doha earlier this year, and you just realise that this mass imprisonment of Palestinians is actually part of a much bigger political game."
"I'm very concerned about it [the massacre] and you have to look at the big picture: in whose interests is it to destabilise the new government in Egypt? In whose interest is it to kill Egyptians, other than Israel, concerned at the growing closeness of relationship between Palestine and the new Egyptian government?"
