„Is it always permissible to speak of the extension of a concept, of a class? And if not, how do we recognize the exceptional cases? Can we always infer from the extension of one concept's coinciding with that of a second, that every object which falls under the first concept also falls under the second?“

„First is the conception of being or existing independent of anything else. Second is the conception of being relative to, the conception of reaction with, something else. Third is the conception of mediation, whereby a first and second are brought into relation.“

—  Charles Sanders Peirce American philosopher, logician, mathematician, and scientist 1839 - 1914

The Architecture of Theories (1891)
Kontext: Three conceptions are perpetually turning up at every point in every theory of logic, and in the most rounded systems they occur in connection with one another. They are conceptions so very broad and consequently indefinite that they are hard to seize and may be easily overlooked. I call them the conceptions of First, Second, Third. First is the conception of being or existing independent of anything else. Second is the conception of being relative to, the conception of reaction with, something else. Third is the conception of mediation, whereby a first and second are brought into relation.

„A philosophy which emphasises the idea of the One, is generally a dualistic philosophy in which the conception of Second receives exaggerated attention: for this One (though of course involving the idea of First) is always the other of a manifold which is not one.“

—  Charles Sanders Peirce American philosopher, logician, mathematician, and scientist 1839 - 1914

The Architecture of Theories (1891)
Kontext: The origin of things, considered not as leading to anything, but in itself, contains the idea of First, the end of things that of Second, the process mediating between them that of Third. A philosophy which emphasises the idea of the One, is generally a dualistic philosophy in which the conception of Second receives exaggerated attention: for this One (though of course involving the idea of First) is always the other of a manifold which is not one. The idea of the Many, because variety is arbitrariness and arbitrariness is repudiation of any Secondness, has for its principal component the conception of First. In psychology Feeling is First, Sense of reaction Second, General conception Third, or mediation. In biology, the idea of arbitrary sporting is First, heredity is Second, the process whereby the accidental characters become fixed is Third. Chance is First, Law is Second, the tendency to take habits is Third. Mind is First, Matter is Second, Evolution is Third.

„Every object that we perceive appears in innumerable aspects. The concept of the object is the invariant of all these aspects.“

—  Max Born physicist 1882 - 1970

The close of his Nobel lecture: "The Statistical Interpretations of Quantum Mechanics" (11 December 1954) http://nobelprize.org/nobel_prizes/physics/laureates/1954/born-lecture.html
Kontext: Can we call something with which the concepts of position and motion cannot be associated in the usual way, a thing, or a particle? And if not, what is the reality which our theory has been invented to describe?
The answer to this is no longer physics, but philosophy. … Here I will only say that I am emphatically in favour of the retention of the particle idea. Naturally, it is necessary to redefine what is meant. For this, well-developed concepts are available which appear in mathematics under the name of invariants in transformations. Every object that we perceive appears in innumerable aspects. The concept of the object is the invariant of all these aspects. From this point of view, the present universally used system of concepts in which particles and waves appear simultaneously, can be completely justified. The latest research on nuclei and elementary particles has led us, however, to limits beyond which this system of concepts itself does not appear to suffice. The lesson to be learned from what I have told of the origin of quantum mechanics is that probable refinements of mathematical methods will not suffice to produce a satisfactory theory, but that somewhere in our doctrine is hidden a concept, unjustified by experience, which we must eliminate to open up the road.

„Until now, Central America has always understood that governments that we recognize and support stay in power, while those we do not recognize and support, fall“

—  Noam Chomsky american linguist, philosopher and activist 1928

Quotes 1960s-1980s, 1980s, Talk at University of California, Berkeley, 1984
Kontext: There have been times, however, when US officials have described what's going on in relatively frank terms; sometimes quite clearly. One put the matter in these words: "The Central American area down to and including the Isthmus of Panama constitutes a legitimate sphere of influence for the United States [... ] We do control the destinies of Central America and we do so for the simple reason that the national interest absolutely dictates such a course [... ] We must decide whether we shall tolerate the interference of any other power in Central American affairs, or insist upon our own dominant position [... ] Until now, Central America has always understood that governments that we recognize and support stay in power, while those we do not recognize and support, fall [... ] Nicaragua has become a test case, it is difficult to see how we can afford to be defeated." That's fairly familiar. These remarks were made by Under Secretary of State Robert Olds in 1927, and the outside power that he was concerned about was Mexico. [audience laughter] Mexico at that time was a Russian proxy. We were no longer fighting Huns in the Dominican Republic, now we were fighting Russians in Nicaragua, and in particular the Russian proxy Mexico. Mexico was then a proxy of the Bolsheviks, so the Marines had to be sent in, once again, and they established Somoza, and established the National Guard which was the basis for American power throughout the region, and in fact one of the most effective murder-incorporated forces down there for many years. They killed Sandino, he was killed off by stealth couple of years later, the guerilla leader. As President Coolidge sent the Marines in, he made the following declaration: "Mexico is on trial before the world." Mexico is on trial before the world as a proxy of the Soviet Union when we send the Marines into Nicaragua. Now things have changed a little bit, now it's Nicaragua that's threatening Mexico as a Russian proxy... But again there's the same conclusion, you know, kill the spics and the niggers and so on. That follows no matter who's the proxy for who. And all of this is repeated at every moment of history with great seriousness and awe and so on as if it had some meaning, as if it wasn't just some black comedy.
