Philosophy

"It is not human life only, not human life as such, that ought to be sacred to us, but human feelings. The human capacity of suffering is what we should cause to be respected, not the mere capacity of existing."

"A person may cause evil to others not only by his actions but by his inaction, and in either case he is justly accountable to them for the injury. The latter case, it is true, requires a much more cautious exercise of compulsion than the former. To make any one answerable for doing evil to others, is the rule; to make him answerable for not preventing evil is, comparatively speaking, the exception. Yet there are many cases clear enough and grave enough to justify that exception."

"The satisfaction of the much stigmatized animal propensities," or carnal desires," whatever they are, may be just as exemplary and noble as the satisfaction of the desire for knowledge or opulence; and they are, in fact, frequently more so. The only rational characterization of a low desire is one incapable of yielding to the universe in its satisfaction large returns of happiness. And a high desire is simply one affording to the universe in its satisfaction wide and profound welfare. The only reason why any desire, so-called "high" or so-called low," should be kept in abeyance is that its satisfaction will not contribute to the utilities. There is no reason why any desire capable of satisfaction possessed by a living being should not be satisfied, except that its satisfaction may interfere with the satisfaction of other more valuable desires possessed by the being himself or by other beings."

"Each living being of the universe, therefore, sustains to every other living being the relation of possible right and wrong, but to the insentient universe no such relation exists. Right is that relation which is conducive to happiness, or welfare, or complete living, or whatever synonym is preferred. Wrong is that which conduces to the opposite of happiness—misery, ill-fare, maladaptation."

"Why should living beings struggle against each other, except as they struggle to advance the general welfare? Happiness is just as valuable and just as beautiful a thing in one being as in another. Some have greater talent for it than have others but it is a state of sweetness and elation always and everywhere. And each living being, in deliberating on the problem of the proprieties, should realize the fact that, as a matter of fact, it is a matter of indifference whether this relation belongs to his sensorium or to some other sensorium. It is insane for each being to insist that he, as an organism, is the one organism to whom pleasure is indispensable. The only indispensable is that pleasure be maximized. If a definite amount of happiness is to be experienced, it is, in the eyes of the absolute, a matter of indifference whether this happiness is experienced by one individual or by another, by self or by some other conscious portion of the universe."

"Those things, thoughts, beings, acts, and instincts which help us to the pleasurable experiences of life we call good, and those which deprive us of pleasure or which bring upon us painful experiences we call bad. This is the supreme standard—Utility. Is the thing, thought, being, act, or impulse useful? Does it lead directly or indirectly to happiness and well-being? If it does, it is right, proper, and good. If it does not, it is wrong, improper, and bad."

"The well being of others is on an average as important as our own, and should as a general thing be appraised at the same value. If a certain amount of happiness is scheduled to fall to the lot of the earth, it makes absolutely no difference whether it falls on me, or on you, or on somebody a thousand miles away. It would serve the ends of absolute ethics quite as well if it fell on an insect or a horse as if it fell on a man. The only important thing from the standpoint of universal good is that the pleasure be experienced. It is not important what particular individual or species is the beneficiary. It might even go to another world, and be just as satisfactory to a universal well-wisher, who looked at Cosmos from the serene altitudes of pure reason, without any prejudices whatever one way or another in the matter. This is the ideal. It is a long, long way from our natures. But only in so far as we approximate this ideal do we rise above those imperfections of our being which have been ground out by the methods that have operated in the development of life on earth."

"Hedonism, pessimism, utilitarianism, or eudaemonism, all those modes of thinking which measure the worth of things according to pleasure and pain, ... are plausible modes of thought and naïvetés, which every one conscious of creative powers and an artist’s conscience will look down upon with scorn. ... We regard your seriousness as more dangerous than any kind of levity. ... Well-being, as you understand it—is certainly not a goal; it seems to us ... a condition which at once renders man ludicrous and contemptible."

"Critics would argue that conceiving the end of life as a perpetual cosmic orgasm is the reductio ad absurdum of classical utilitarianism. But will posthuman superintelligence respect human conceptions of absurdity?"

"Perfect the Will, the Mind, Feeling, their corporeal organs and their material tools; be useful to yourselves, to your own ones, and to others; and Happiness, insofar as it exists on this earth, will come of itself."

"In their time, Bentham's ideas promoted progress, reform, wider democracy, and the amelioration of undesirable social conditions. Bentham lived... when common people, the "labouring poor," had little voice and no vote... Their toil and sacrifices enhanced the power of the nation, the glory of its rulers, the wealth of industrialists and merchants, and the indolent ease of the aristocrats. Yet here was a philosopher who said that people are people regardless of their social position. ...[L]egislators ought actively to augment the total happiness of the community. Instead of the people serving the state, the state should serve the people. ...[H]is slogan for government was "Be quiet." But he did not worship laissez-faire as a principle to be accepted blindly. ...[T]he state should monopolize the issue of paper money, thereby saving interest on its borrowing. It should... operate life and annuity insurance, and tax inheritance, monopolies, [etc.] ...Bentham's idea of diminishing marginal utility of money suggested an argument for the redistribution of income. ...[M]ore happiness will be gained by the poor... than will be lost by the wealthy... Bentham's devotion to the greatest good for the greatest number led him to... advocate for.. democratic reforms. He supported universal (male) suffrage, equal electoral districts, annual parliaments, and the secret ballot. He opposed the monarchy and the , arguing that only in a democracy do the interest of the gonernors and the governed become identical. ...Bentham urged a system of national education, even for pauper children. Frugality Banks... should... stimulate saving by the poor. should provide jobs for unemployed workers during slack times. ...He designed ...a model prison that would reform criminals rather than punish them. No wonder Bentham and his circle of intellects (including James Mill, John Stuart Mill, and Ricardo) were called "philosophic radicals.""

"It appeared to me obvious that the happiness of mankind should be the aim of all action, and I discovered to my surprise that there were those who thought otherwise. Belief in happiness, I found, was called Utilitarianism, and was merely one among a number of ethical theories. I adhered to it after this discovery."

"This utilitarian view of the mind ... is an external view only, which marks the place and conditions of the mind in nature, but neglects its specific essence. ... If the intellect is a device produced in organic bodies to expedite their processes, these organic bodies must have interests and a chosen direction in their life; otherwise their life could not be expedited, nor could anything be useful to it."

"Utility is the great idol of the age, to which all powers must do service and all talents swear allegiance."

"Those proud Islanders whom many unduly honour, know no watchword but gain and enjoyment. Their zeal for knowledge is only a sham fight, their worldly wisdom a false jewel, skilfully and deceptively composed, and their sacred freedom itself too often and too easily serves self-interest. They are never in earnest with anything that goes beyond palpable utility. All knowledge they have robbed of life and use only as dead wood to make masts and helms for their life's voyage in pursuit of gain."

"The good of any one individual is of no more importance, from the point of view...of the Universe, than the good of any other; unless, that is, there are special grounds for believing that more good is likely to be realized in the one case than in the other."

"We have next to consider who the “all” are, whose happiness is to be taken into account. Are we to extend our concern to all the beings capable of pleasure and pain whose feelings are affected by our conduct? or are we to confine our view to human happiness? The former view is the one adopted by Bentham and Mill, and (I believe) by the Utilitarian school generally: and is obviously most in accordance with the universality that is characteristic of their principle. It is the Good Universal, interpreted and defined as ‘happiness’ or ‘pleasure,’ at which a Utilitarian considers it his duty to aim: and it seems arbitrary and unreasonable to exclude from the end, as so conceived, any pleasure of any sentient being."

"How far we are to consider the interests of posterity when they seem to conflict with those of now-existing human beings? The answer to this, though, seems clear: the time at which a man exists can’t affect the value of his happiness from a universal point of view; so the interests of posterity must concern a utilitarian as much as those of his contemporaries—except in that the effect of his actions on the lives and even the existence of posterity must be more uncertain."

"The core precept of utilitarianism is that we should make the world the best place we can. That means that, as far as it is within our power, we should bring about a world in which every individual has the highest possible level of wellbeing."

"The only justifiable stopping place for the expansion of altruism is the point at which all whose welfare can be affected by our actions are included within the circle of altruism. This means that all beings with the capacity to feel pleasure or pain should be included; we can improve their welfare by increasing their pleasures and diminishing their pains."

"The kind of equality utilitarianism supports is given by Bentham’s formula...: ‘everybody to count for one, and nobody for more than one’...Utilitarianism seeks to maximize happiness, and in deciding how to calculate whether happiness is being maximized, no one’s pleasures or pains should count for less because they are peasants rather than aristocrats, slaves rather than slave-owners, Africans rather than Europeans, poor rather than rich, illiterates rather than doctors of philosophy, children rather than adults, females rather than males, or even, as we have seen, non-human animals rather than human beings."

"The sentiment to which [the utilitarian] appeals is generalized benevolence, that is, the disposition to seek happiness, or...good consequences, for all mankind, or perhaps for all sentient beings."

"Another type of ultimate disagreement between utilitarians, whether hedonistic or ideal, can arise over whether we should try to maximize the average happiness of human beings...or whether we should try to maximize the total happiness or goodness...Would you be quite indifferent between (a) a universe containing only one million happy sentient beings, all equally happy, and (b) a universe containing two million happy beings, each neither more nor less happy than any in the first universe? Or would you, as a humane and sympathetic person, give a preference to the second universe? I myself cannot help feeling a preference for the second universe."

"It's the flock, the grove, that matters. Our responsibility is to species, not to specimens; to communities, not to individuals."

"Before the age of adulteration it was held that behind each work there stood some conception of its perfect execution. It was this that gave zest to labor and served to measure the degree of success. To the extent that the concept obtained, there was a teleology in work, since the laborer toiled not merely to win sustenance but to see this ideal embodied in his creation. Pride in craftsmanship is well explained by saying that to labor is to pray, for conscientious effort to realize an ideal is a kind of fidelity. The craftsman of old time did not hurry, because the perfect takes no account of time and shoddy work is a reproach to character. But character itself is an expression of self-control, which does not come of taking the easiest way. Where character forbids self-indulgence, transcendence still hovers around."

"[ Fuzzy logic is ] a logic whose distinguishing features are (i) fuzzy truth-values expressed in linguistic terms, e.g., true, very true, more or less true, or somewhat true, false, nor very true and not very false, etc2.; (2) imprecise truth tables; and (3) rules of inference whose validity is relative to a context rather than exact."

"Roughly speaking: to say of two things that they are identical is nonsense, and to say of one thing that it is identical with itself is to say nothing."

"Memory, then, is a necessary part of the logical faculty. ... The proposition A = A must have a psychological relation to time, otherwise it would be At1 = At2."

"Logic is a law which must be obeyed, and man realizes himself only in so far as he is logical. He finds himself in cognition."

"As to the most prudent logicians might venture to deduce from a skein of wool the probable existence of a sheep; so you, from the raw stuff of perception, may venture to deduce a universe which transcends the reproductive powers of your loom."

"Logic tends to reduce everything to identities and genera, to each representation having no more than one single and self-same content in whatever place, time, or relation it may occur to us. And there is nothing that remains the same for two successive moments of its existence. My idea of God is different each time that I conceive it. Identity, which is death, is the goal of the intellect."

"The moment we stop assuming that the ideas of any milieu form static 'propositional systems', and recognize that they constitute historically developing 'conceptual populations', we are free to abandon also the philosophers' traditional assumption that rationality is a sub-species of logicality. ...In non-intellectual contexts... we judge the rationality of a man's conduct, not by how he habitually behaves, but rather how far he modifies his behaviour in new and unfamiliar situations, and it is arguable that the rationality of intellectual performances should be judged, correspondingly, by considering, not the internal consistency of a man's habitual concepts and beliefs, but rather the manner in which he modifies this intellectual position in the face of new and unforeseen experiences."

"Poetry — No definition of poetry is adequate unless it be poetry itself. The most accurate analysis by the rarest wisdom is yet insufficient, and the poet will instantly prove it false by setting aside its requisitions. It is indeed all that we do not know. The poet does not need to see how meadows are something else than earth, grass, and water, but how they are thus much. He does not need discover that potato blows are as beautiful as violets, as the farmer thinks, but only how good potato blows are. The poem is drawn out from under the feet of the poet, his whole weight has rested on this ground. It has a logic more severe than the logician's. You might as well think to go in pursuit of the rainbow, and embrace it on the next hill, as to embrace the whole of poetry even in thought."

"It takes extraordinary wisdom and self-control to accept that many things have a logic we do not understand that is smarter than our own."

"An idea starts to be interesting when you get scared of taking it to its logical conclusion."

"Logic is in the eye of the logician."

"Logic is the beginning of wisdom, not the end."

"Conceptual graphs are system of logic based on the existential graphs of Charles Sanders Peirce and the semantic networks of artificial intelligence. The purpose of the system is to express meaning in a form that is logically precise, humanly readable, and computationally tractable."

"[My aim is] to design logic as a calculating discipline, especially to give access to the exact handling of relative concepts, and, from then on, by emancipation from the routine claims of natural language, to withdraw any fertile soil from "cliché" in the field of philosophy as well. This should prepare the ground for a scientific universal language that, widely differing from linguistic efforts like Volapük [a universal language like Esperanto, very popular in Germany at the time], looks more like a sign language than like a sound language."

"When emotion brings us ghosts from the past, only logic can root us in the present."

"A crisis in doctrine occurred when they discovered that the square root of two was irrational. That is: the square root of two could not be represented as the ratio of two whole numbers, no matter how big they were. "Irrational" originally meant only that. That you can't express a number as a ratio. But for the Pythagoreans it came to mean something else, something threatening, a hint that their world view might not make sense, the other meaning of "irrational"."

""I refuse to prove that I exist," says God, "for proof denies faith, and without faith, I am nothing." "Oh," says man, "but the Babel fish is a dead give-away, isn't it? It proves You exist, and so therefore You don't." "Oh, I hadn't thought of that," says God, who promptly vanishes in a puff of logic. "Ah, that was easy," says man, and for an encore goes on to prove that black is white, and gets killed on the next zebra crossing. Most leading theologians claim that this argument is a load of dingo's kidneys."

"Pure logic is the ruin of the spirit."

"The apparent world goes through developments which are the same as those the logician goes through if he starts from Pure Being and travels on to the Absolute Idea. [...] Why the world should go through this logical evolution is not clear; one is tempted to suppose that the Absolute Idea did not quite understand itself at first, and made mistakes when it tried to embody itself in events. But this, of course, was not what Hegel would have said."

"I once received a letter from an eminent logician, Mrs. Christine Ladd Franklin, saying that she was a solipsist, and was surprised that there were no others. Coming from a logician, this surprise surprised me."

"All traditional logic habitually assumes that precise symbols are being employed. It is therefore not applicable to this terrestial life but only to an imagined celestial existence... logic takes us nearer to heaven than other studies."

"The question of "unreality," which confronts us at this point, is a very important one. Misled by grammar, the great majority of those logicians who have dealt with this question have dealt with it on mistaken lines. They have regarded grammatical form as a surer guide in analysis than, in fact, it is. And they have not known what differences in grammatical form are important."

"Mathematics and logic, historically speaking, have been entirely distinct studies. Mathematics has been connected with science, logic with Greek. But both have developed in modern times: logic has become more mathematical and mathematics has become more logical. The consequence is that it has now become wholly impossible to draw a line between the two; in fact, the two are one. They differ as boy and man: logic is the youth of mathematics and mathematics is the manhood of logic. This view is resented by logicians who, having spent their time in the study of classical texts, are incapable of following a piece of symbolic reasoning, and by mathematicians who have learnt a technique without troubling to inquire into its meaning or justification. Both types are now fortunately growing rarer. So much of modern mathematical work is obviously on the border-line of logic, so much of modern logic is symbolic and formal, that the very close relationship of logic and mathematics has become obvious to every instructed student. The proof of their identity is, of course, a matter of detail: starting with premises which would be universally admitted to belong to logic, and arriving by deduction at results which as obviously belong to mathematics, we find that there is no point at which a sharp line can be drawn, with logic to the left and mathematics to the right. If there are still those who do not admit the identity of logic and mathematics, we may challenge them to indicate at what point, in the successive definitions and deductions of Principia Mathematica, they consider that logic ends and mathematics begins. It will then be obvious that any answer must be quite arbitrary."

"Of course I'm inconsistent! Only logicians and cretins are consistent!"

"The utility of a science which enables men to take cognizance of the travellers on the mind's highway, and excludes those disorderly interlopers, verbal fallacies, needs but small attestation. Its searching penetration by definition alone, before which even mathematical precision fails, would especially commend it to those whom the abstruseness of the study does not terrify, and who recognise the valuable results which must attend discipline of mind. Like a medicine, though not a panacea for every ill, it has the health of the mind for its aim, but requires the determination of a powerful will to imbibe its nauseating yet wholesome influence: it is no wonder therefore that puny intellects, like weak stomachs, abhor and reject it."
