“Speak to any small man of a high, majestic Reformation, of a high majestic Luther; and forthwith he sets about “accounting” for it; how the “circumstances of the time” called for such a character, and found him, we suppose, standing girt and road-ready, to do its errand; how the “circumstances of the time” created, fashioned, floated him quietly along into the result; how, in short, this small man, had he been there, could have per formed the like himself! For it is the “force of circumstances” that does everything; the force of one man can do nothing. Now all this is grounded on little more than a metaphor. We figure Society as a “Machine,” and that mind is opposed to mind, as body is to body; whereby two, or at most ten, little minds must be stronger than one great mind. Notable absurdity! For the plain truth, very plain, we think is, that minds are opposed to minds in quite a different way; and one man that has a higher Wisdom, a hitherto unknown spiritual Truth in him, is stronger, not than ten men that have it not, or than ten thousand, but than all men that have it not; and stands among them with a quite ethereal, angelic power, as with a sword out of Heaven's own armory, sky-tempered, which no buckler, and no tower of brass, will finally withstand.”

“Man enjoys the happiness he feels, woman the happiness she gives. This difference, so essential and yet so seldom noticed, has a marked difference on the whole of their respective behaviour. A man's pleasure is to satisfy desires, a woman's is chiefly to arouse them.”

L’homme jouit du bonheur qu’il ressent, et la femme de celui qu’elle procure. Cette différence, si essentielle et si peu remarquée, influe pourtant, d'une manière bien sensible, sur la totalité de leur conduite respective. Le plaisir de l’un est de satisfaire des désirs, celui de l’autre est surtout de les faire naître.

“The fact that each nation came to believe in the virtue of whatever policy happened to be in effect when recovery began supports [the] argument that haphazard economic vacillations play an important role in determining which policy strategies become constructed as economically efficacious. This also tends to undermine the realist/utilitarian view, which suggests that policy improves over time as rational policymakers learn more about universal economic laws from experience, because wildly inconsistent policies won favor in different contexts.”

“One of the advantages of being over forty is that one begins to learn the difference between knowing and realising.”

Gustav Holst (1874–1934) English composer

Letter to W G Whittaker, 1914, quoted in Paul Holmes Holst p. 62.

“The 19th and first half of the 20th century conceived of the world as chaos. Chaos was the oft-quoted blind play of atoms, which, in mechanistic and positivistic philosophy, appeared to represent ultimate reality, with life as an accidental product of physical processes, and mind as an epi-phenomenon. It was chaos when, in the current theory of evolution, the living world appeared as a product of chance, the outcome of random mutations and survival in the mill of natural selection. In the same sense, human personality, in the theories of behaviorism as well as of psychoanalysis, was considered a chance product of nature and nurture, of a mixture of genes and an accidental sequence of events from early childhood to maturity.
Now we are looking for another basic outlook on the world -- the world as organization. Such a conception -- if it can be substantiated -- would indeed change the basic categories upon which scientific thought rests, and profoundly influence practical attitudes.
This trend is marked by the emergence of a bundle of new disciplines such as cybernetics, information theory, general system theory, theories of games, of decisions, of queuing and others; in practical applications, systems analysis, systems engineering, operations research, etc. They are different in basic assumptions, mathematical techniques and aims, and they are often unsatisfactory and sometimes contradictory. They agree, however, in being concerned, in one way or another, with "systems," "wholes" or "organizations"; and in their totality, they herald a new approach.”

Ludwig von Bertalanffy (1901–1972) austrian biologist and philosopher

Some Aspects of System Theory in Biology, p. 166-167 as quoted in Lilienfeld (1978, pp. 7-8) and Alexander Laszlo and Stanley Krippner (1992) " Systems Theories: Their Origins, Foundations, and Development http://archive.syntonyquest.org/elcTree/resourcesPDFs/SystemsTheory.pdf" In: J.S.

“Let us begin by observing that the word "system" is almost never used by itself; it is generally accompanied by an adjective or other modifier: physical system; biological system; social system; economic system; axiom system; religious system; and even "general" system. This usage suggests that, when confronted by a system of any kind, certain of its properties are to be subsumed under the adjective, and other properties are subsumed under the "system," while still others may depend essentially on both. The adjective describes what is special or particular; i. e., it refers to the specific "thinghood" of the system; the "system" describes those properties which are independent of this specific "thinghood."
This observation immediately suggests a close parallel between the concept of a system and the development of the mathematical concept of a set. Given any specific aggregate of things; e. g., five oranges, three sticks, five fingers, there are some properties of the aggregate which depend on the specific nature of the things of which the aggregate is composed. There are others which are totally independent of this and depend only on the "set-ness" of the aggregate. The most prominent of these is what we can call the cardinality of the aggregate…
It should now be clear that system hood is related to thinghood in much the same way as set-ness is related to thinghood. Likewise, what we generally call system properties are related to systemhood in the same way as cardinality is related to set-ness. But systemhood is different from both set-ness and from thinghood; it is an independent category.”

“The range of H 1255 is only four tenths of a magnitude, and on account of its brightness it is difficult to observe on all plates except those taken with the 1-inch Cooke lens. It seemed necessary, therefore, to take unusual precautions in order to secure accurate observations, and to give each one its full weight. Accordingly, one hundred and thirty six photographs were selected, including nearly all of those taken with the Cooke lens, and also those taken with the 8 inch Bache Telescope on which the variable was certainly faint. Four independent estimates of brightness were made on each plate, and means were taken, thus reducing the probable error one half. The phase was computed for each observation, thus covering all parts of the light curve. …H 1255 and H 1303 differ from the other variables in a marked degree as in each case the duration of the phase of minimum is very long in proportion to the length of the period. This fact led to considerable difficulty in determining their periods as they were apparently at their minimum brightness for some time before and after the actual minima occurred. In H 1255, the change in brightness is obviously continuous throughout the period, although it is much more rapid near minimum than near maximum. This is clearly seen in Plate IV, Figs. 5 and 6.”

“The children of fighter pilots tell different stories than other kids do. None of our fathers can write a will or sell a life insurance policy or fill out a prescription or administer a flu shot or explain what a poet meant. We tell of fathers who land on aircraft carriers at pitch-black night with the wind howling out of the China Sea. Our fathers wiped out aircraft batteries in the Philippines and set Japanese soldiers on fire when they made the mistake of trying to overwhelm our troops on the ground. Your Dads ran the barber shops and worked at the post office and delivered the packages on time and sold the cars, while our Dads were blowing up fuel depots near Seoul, were providing extraordinarily courageous close air support to the beleaguered Marines at the Chosin Reservoir, and who once turned the Naktong River red with blood of a retreating North Korean battalion. We tell of men who made widows of the wives of our nations' enemies and who made orphans out of all their children. You don't like war or violence? Or napalm? Or rockets? Or cannons or death rained down from the sky? Then let's talk about your fathers, not ours. When we talk about the aviators who raised us and the Marines who loved us, we can look you in the eye and say "you would not like to have been American's enemies when our fathers passed overhead". We were raised by the men who made the United States of America the safest country on earth in the bloodiest century in all recorded history. Our fathers made sacred those strange, singing names of battlefields across the Pacific: Guadalcanal, Iwo Jima, Okinawa, the Chosin Reservoir, Khe Sanh and a thousand more. We grew up attending the funerals of Marines slain in these battles. Your fathers made communities like Beaufort decent and prosperous and functional; our fathers made the world safe for democracy.”

“Everything in nature completes its action through its own force and species alone… as, for example, fire by its own force dries and consumes and does many things. Therefore vision must perform the act of seeing by its own force. But the act of seeing is the perception of a visible object at a distance, and therefore vision perceives what is visible by its own force multiplied to the object. Moreover, the species of the things of world are not fitted by nature to effect the complete act of vision at once, because of its nobleness. Hence these must be aided by the species of the eye, which travels in the locality of the visual pyramid, and changes the medium and ennobles it, and renders it analogous to vision, and so prepares the passage of the species itself of the visible object… Concerning the multiplication of this species, moreover, we are to understand that it lies in the same place as the species of the thing seen, between the sight and the thing seen, and takes place along the pyramid whose vertex is in the eye and base in the thing seen. And as the species of an object in the same medium travels in a straight path and is refracted in different ways when it meets a medium of another transparency, and is reflected when it meets the obstacles of a dense body; so is it also true of the species of vision that it travels altogether along the path of the species itself of the visible object.”

Bacon, like Grosseteste, asserts that both the active extramitted species of vision from the eye, and the intramitted species of light from object seen, were necessary for sight.

“De Bellaigue is at pains to portray Mossadegh as — in the words of the jacket copy — “one of the first liberals of the Middle East, a man whose conception of liberty was as sophisticated as any in Europe or America.” But the trouble is, there is nothing in Mossadegh’s career — spanning half a century, as provincial governor, cabinet minister, and finally prime minister — to portray him as even remotely a lover of liberty. De Bellaigue quotes Mossadegh as saying that a trusted leader is “that person whose every word is accepted and followed by the people.” To which de Bellaigue adds: “His understanding of democracy would always be coloured by traditional ideas of Muslim leadership, whereby the community chooses a man of outstanding virtue and follows him wherever he takes them.” Word for word, that could have been the late Ayatollah Khomeini’s definition of a true leader. Mossadegh also made a habit of appearing in his street meetings with a copy of the Koran in hand. According to de Bellaigue, Mossadegh liked to say that “anyone forgetting Islam is base and dishonourable, and should be killed.” During his premiership, Mossadegh demonstrated his dictatorial tendency to the full: Not once did he hold a full meeting of the council of ministers, ignoring the constitutional rule of collective responsibility. He dissolved the senate, the second chamber of the Iranian parliament, and shut down the Majlis, the lower house. He suspended a general election before all the seats had been decided and chose to rule with absolute power. He disbanded the high council of national currency and dismissed the supreme court. During much of his tenure, Tehran lived under a curfew while hundreds of his opponents were imprisoned. Toward the end of his premiership, almost all of his friends and allies had broken with him. Some even wrote to the secretary general of the United Nations to intervene to end Mossadegh’s dictatorship. But was Mossadegh a man of the people, as de Bellaigue portrays him? Again, the author’s own account provides a different picture. A landowning prince and the great-great-grandson of a Qajar king, Mossadegh belonged to the so-called thousand families who owned Iran. He and all his children were able to undertake expensive studies in Switzerland and France. The children had French nannies and, when they fell sick, were sent to Paris or Geneva for treatment. (De Bellaigue even insinuates that Mossadegh might have had a French sweetheart, although that is improbable.) On the one occasion when Mossadegh was sent to internal exile, he took with him a whole retinue, including his cook… As a model of patriotism, too, Mossadegh is unconvincing. According to his own memoirs, at the end of his law studies in Switzerland, he had decided to stay there and acquire Swiss citizenship. He changed his mind when he was told that he would have to wait ten years for that privilege. At the same time, Farmanfarma secured a “good post” for him in Iran, tempting him back home.”

“I don't want to offend people right out of the gate. I know that some of you believe and I certainly don’t want to mock the myths that define some of you, but um. I choose not to believe in god. That's ok still, i can do that, right? It's my choice to go through life filled with dread, panic and fear... because I think that's a more objective and real way to live. Just be like…"Aaaaahh' what's gonna happen?!" I think that's needed, honestly. And again I don't want to make fun of what you believe in. I think the reason Jesus is so popular, just on a celebrity level, is that he died at the peak of his career, ok. He was…hear me out…. he was young, he was hot. He was well spoken from all accounts. I really think it would have been different had he lived longer, alright. Say had he gotten old enough to get bitter. Alright, just hear me out. Picture there's a third testament to the bible' alright. This point Jesus is in his 50's. He's got one apostle left. And the book opens with him knee deep in water saying, "I used to be able to do this!" The apostle's saying, "Come on…don't yell at the water, Jesus. Come on in. It's not your day, buddy. Come on. People are gathering for the wrong reason. Can we just go, please. Let's go to the deli…we'll have a sandwich. We'll try again tomorrow. Come on, yes you are god, come on. And again, you know, if you're a religious person, I understand why you believe. It makes you feel better, you know. But a lot of us do not have the patience or disposition to have faith or belief. Thank god there's medication for those people because if you're properly medicated, it will provide roughly the same effect as religion, you know. If you're on the right combination of anti-depressants, it will alleviate your ability to see the truth clearly and provide a false sense of hope.”

“I am trying to put the distributional question and the study of long-run trends back at the heart of economic analysis. In that sense, I am pursuing a tradition which was pioneered by the economists of the 19th century, including David Ricardo and Karl Marx. One key difference is that I have a lot more historical data. With the help of Tony Atkinson, Emmanuel Saez, Facundo Alvaredo, Gilles Postel-Vinay, Jean-Laurent Rosenthal, Gabriel Zucman and many other scholars, we have been able to collect a unique set of data covering three centuries and over 20 countries. This is by far the most extensive database available in regard to the historical evolution of income and wealth. This book proposes an interpretative synthesis based upon this collective data collection project.”

In answer of the question: "Your book fits oddly into the canon of contemporary economics. It focuses not on growth and its determinants, but on how the spoils of growth are divided. In that sense, it reminds us of similar concerns in a book of similar title written 150 years ago: Karl Marx’s “Capital.” What parallels would you draw between the two?"

“The ordinary surroundings of life which are esteemed by men (as their actions testify) to be the highest good, may be classed under the three heads — Riches, Fame, and the Pleasures of Sense: with these three the mind is so absorbed that it has little power to reflect on any different good.”

Baruch Spinoza (1632–1677) Dutch philosopher

I, 3
Variant translation: The things which … are esteemed as the greatest good of all … can be reduced to these three headings, to wit : Riches, Fame, and Pleasure. With these three the mind is so engrossed that it cannot scarcely think of any other good.
On the Improvement of the Understanding (1662)

“If two objects or human beings show similar behaviour in all their relevant aspects open to observation, the assumption of some unobservable hidden difference between them must be regarded as a completely gratuitous hypothesis and one contrary to sound scientific method.”

John Harsanyi (1920–2000) hungarian economist

Harsanyi, J. C. (1955). "Cardinal Welfare, Individualistic Ethics, and Interpersonal Comparisons of Utility". J. Polit. Economy 63 (4): p. 317

“A conceptual level view of an object design describes the key abstractions. While someone might think of key abstractions as being nothing more or nothing less than high-level descriptions of "candidate classes", I prefer to consider a conceptual design from a slightly different angle--I'm thinking about design at a slightly different level.
An object-oriented application is a set of interacting objects. Each object is an implementation of one or more roles. A role supports a set of related (cohesive) responsibilities. A responsibility is an obligation to perform a task or know certain information. And objects don't work in isolation, they collaborate with others in a community to perform the overall responsibilities of the application. So a conceptual view, at least to start, is a distillation of the key object roles and their responsibilities (stated at a fairly high level). More than likely (unless you form classification hierarchies and use inheritance and composition techniques) many candidates you initially model will map directly to a single class in some inheritance hierarchy. But I like to open up possibilities by think first of roles and responsibilities, and then as a second step towards a specification-level view, mapping these candidates to classes and interfaces.”

“To help us to understand three-dimensional spaces, two-dimensional analogies may be very useful… A two-dimensional space of zero curvature is a plane, say a sheet of paper. The two-dimensional space of positive curvature is a convex surface, such as the shell of an egg. It is bent away from the plane towards the same side in all directions. The curvature of the egg, however, is not constant: it is strongest at the small end. The surface of constant positive curvature is the sphere… The two-dimensional space of negative curvature is a surface that is convex in some directions and concave in others, such as the surface of a saddle or the middle part of an hour glass. Of these two-dimensional surfaces we can form a mental picture because we can view them from outside… But… a being… unable to leave the surface… could only decide of which kind his surface was by studying the properties of geometrical figures drawn on it. …On the sheet of paper the sum of the three angles of a triangle is equal to two right angles, on the egg, or the sphere, it is larger, on the saddle it is smaller. …The spaces of zero and negative curvature are infinite, that of positive curvature is finite. …the inhabitant of the two-dimensional surface could determine its curvature if he were able to study very large triangles or very long straight lines. If the curvature were so minute that the sum of the angles of the largest triangle that he could measure would… differ… by an amount too small to be appreciable… then he would be unable to determine the curvature, unless he had some means of communicating with somebody living in the third dimension…. our case with reference to three-dimensional space is exactly similar. …we must study very large triangles and rays of light coming from very great distances. Thus the decision must necessarily depend on astronomical observations.”

“In theory, there is no difference between theory and practice. But, in practice, there is.”

The earliest known appearance in print of this quote is Benjamin Brewster in the October 1881 - June 1882 issue of "The Yale Literary Magazine." Brewster asks, "What does his lucid explanation amount to but this, that in theory there is no difference between theory and practice, while in practice there is?" See page 202. https://books.google.com/books?id=iJ9MAAAAMAAJ&printsec=frontcover&vq=%22no+difference%22#v=onepage&q&f=false It has also been attributed by Doug Rosenberg and Matt Stephens (2007) Use Case Driven Object Modeling with UMLTheory and Practice p. xxvii as well as Walter J. Savitch, Pascal: An Introduction to the Art and Science of Programming (1984), where it is attributed as a "remark overheard at a computer science conference". It circulated as an anonymous saying for more than ten years before attributions to van de Snepscheut and Yogi Berra began to appear (and later still to various others).
