“Ebbinghaus: Language is a system of conventional signs that can be voluntarily produced at any time.
Croce: Language is articulated, limited sound organized for the purpose of expression.
Dittrich: Language is the totality of expressive abilities of individual human beings and animals capable of being understood by at least one other individual.
Eisler: Language is any expression of experiences by a creature with a soul.
B. Erdmann: Language is not a kind of communication of ideas but a kind of thinking: stated or formulated thinking. Language is a tool, and in fact a tool or organ of thinking that is unique to us as human beings.
Forbes: Language is an ordered sequence of words by which a speaker expresses his thoughts with the intention of making them known to a hearer.
J. Harris : Words are the symbols of ideas both general and particular: of the general, primarily, essentially and immediately; of the particular, only secondarily, accidentally and mediately.
Hegel: Language is the act of theoretical intelligence in its true sense, for it is its outward expression.
Jespersen: Language is human activity which has the aim of communicating ideas and emotions.
Jodl: Verbal language is the ability of man to fashion, by means of combined tones and sounds based on a limited numbers of elements, the total stock of his perceptions and conceptions in this natural tone material in such a way that this psychological process is clear and comprehensible to others to its least detail.
Kainz : Language is a structure of signs, with the help of which the representation of ideas and facts may be effected, so that things that are not present, even things that are completely imperceptible to the senses, may be represented.
De Laguna: Speech is the great medium through which human co-operation is brought about.
Marty: Language is any intentional utterance of sounds as a sign of a psychic state.
Pillsbury-Meader: Language is a means or instrument for the communication of thought, including ideas and emotions.
De Saussure: Language is a system of signs expressive of ideas.
Schuchardt. The essence of language lies in communication.
Sapir: Language is a purely human and non-instinctive method of communicating ideas, emotions and desires by means of a system of voluntarily produced symbols.”

“When an individual appears before others, he wittingly and unwittingly projects a definition of the situation, of which a conception of himself is an important part. When an event occurs which is expressively incompatible with this fostered impression, significant consequences are simultaneously felt in three levels of social reality, each of which involves a different point of reference and a different order of fact.
First, the social interaction, treated here as a dialogue between two teams, may come to an embarrassed and confused halt; the situation may cease to be defined, previous positions may become no longer tenable, and participants may find themselves without a charted course of action…
Secondly, in addition to these disorganizing consequences for action at the moment, performance disruptions may have consequences of a more far-reaching kind. Audiences tend to accept the self projected by the individual performer during any current performance as a responsible representative of his colleague-grouping, of his team, and of his social establishment…
Finally, we often find that the individual may deeply involve his ego in his identification with a particular role, establishment, and group and in his self-conception as someone who does not disrupt social interaction or let down the social units which depend upon that interaction.”

“Juggling is such a white thing, as well, when you think about it. No, just the whole concept. You have so much stuff that, at some point, you are like: "I can't even hold all of this stuff! I'll have to throw some of it in the air!" That's probably how juggling started. Someone was like: "Wow, you have three things, but you only have two hands. Would you like to share something with me?" "No, no, I'll figure this out."”

“In the penultimate decade of the twentieth century science is sufficiently advanced to resolve the puzzles that stymied scientists in the last century and demonstrate, without metaphysical speculation, the consistency of evolution in all realms of experience.

“The way in which the irrational numbers are usually introduced is based directly upon the conception of extensive magnitudes—which itself is nowhere carefully defined—and explains number as the result of measuring such a magnitude by another of the same kind. Instead of this I demand that arithmetic shall be developed out of itself.”

Richard Dedekind (1831–1916) German mathematician

Footnote: The apparent advantage of the generality of this definition of number disappears as soon as we consider complex numbers. According to my view, on the other hand, the notion of the ratio between two numbers of the same kind can be clearly developed only after the introduction of irrational numbers.

“Whereas the conception of space and time as a four-dimensional manifold has been very fruitful for mathematical physicists, its effect in the field of epistemology has been only to confuse the issue. Calling time the fourth dimension gives it an air of mystery. One might think that time can now be conceived as a kind of space and try in vain to add visually a fourth dimension to the three dimensions of space. It is essential to guard against such a misunderstanding of mathematical concepts. If we add time to space as a fourth dimension it does not lose any of its peculiar character as time. …Musical tones can be ordered according to volume and pitch and are thus brought into a two dimensional manifold. Similarly colors can be determined by the three basic colors red, green and blue… Such an ordering does not change either tones or colors; it is merely a mathematical expression of something that we have known and visualized for a long time. Our schematization of time as a fourth dimension therefore does not imply any changes in the conception of time. …the space of visualization is only one of many possible forms that add content to the conceptual frame. We would therefore not call the representation of the tone manifold by a plane the visual representation of the two dimensional tone manifold.”

“Ever since its emergence a few months ago, the declared ambition of the startup caliphate of the Islamic State has been to “wipe out every trace of Infidel influence” in areas under its control. Yet, with each passing day, it becomes more clear that, its deadly fantasies notwithstanding, the IS can’t escape from a world created and dominated by the Infidel. Start with the name that the IS, or Daesh in Arabic, has chosen for itself: ad-dawlat al-Islamiyah, or “Islamic Government.” The concepts of “state” and “government” are entirely Western, not adopted by Muslim peoples until the 19th century. The very words “state” and “government” are never mentioned in the Quran. Daesh’s “caliph” has also appointed a number of vizirs. This, too, is un-Islamic. Of Persian origin, the word vizir designated high officials of the pre-Islamic Sasanian Empire overthrown by Arab Muslim warriors in the 7th century. Mohammad had no vizirs, nor did any of his four immediate successors, the so-called “Well Guided caliphs…” The Islamic State’s most noteworthy embrace of the works of the “Infidel,” however, is surely its use of the satanic Internet. Its personnel, including converts from Europe and North America, regularly display across the Web what seems to be the main, if not the only, thing they’ve learned from Islam: cutting the throats of defenseless captives.”

“It is remarkable that this generalization of plane geometry to surface geometry is identical with that generalization of geometry which originated from the analysis of the axiom of parallels. …the construction of non-Euclidean geometries could have been equally well based upon the elimination of other axioms. It was perhaps due to an intuitive feeling for theoretical fruitfulness that the criticism always centered around the axiom of parallels. For in this way the axiomatic basis was created for that extension of geometry in which the metric appears as an independent variable. Once the significance of the metric as the characteristic feature of the plane has been recognized from the viewpoint of Gauss' plane theory, it is easy to point out, conversely, its connection with the axiom of parallels. The property of the straight line as being the shortest connection between two points can be transferred to curved surfaces, and leads to the concept of straightest line; on the surface of the sphere the great circles play the role of the shortest line of connection… analogous to that of the straight line on the plane. Yet while the great circles as "straight lines" share the most important property with those of the plane, they are distinct from the latter with respect to the axiom of the parallels: all great circles of the sphere intersect and therefore there are no parallels among these "straight lines". …If this idea is carried through, and all axioms are formulated on the understanding that by "straight lines" are meant the great circles of the sphere and by "plane" is meant the surface of the sphere, it turns out that this system of elements satisfies the system of axioms within two dimensions which is nearly identical in all of it statements with the axiomatic system of Euclidean geometry; the only exception is the formulation of the axiom of the parallels.”

Hans Reichenbach (1891–1953) American philosopher

The geometry of the spherical surface can be viewed as the realization of a two-dimensional non-Euclidean geometry: the denial of the axiom of the parallels singles out that generalization of geometry which occurs in the transition from the plane to the curve surface.

“The proletariat thus shared its dictatorship with nobody. As to the question of the "majority", this never troubled Lenin much. In an article "Constitutional Illusions" (Aug. 1917; Works, vol. 25, p. 201) he wrote: "in time of revolution it is not enough to ascertain the ‘ will of the majority’ – you must prove to be stronger at the decisive moment and at the decisive place; you must win … We have seen innumerable examples of the better organized, more politically conscious and better armed minority forcing its will upon the majority and defeating it." (pg. 503) Trotsky, however, answers questions [in The Defence of Terrorism] that Lenin evaded or ignored. "Where is your guarantee, certain wise men ask us, that it is just your party that expresses the interests of historical development? Destroying or driving underground the other parties, you have thereby prevented their political competition with you, and consequently you have deprived yourselves of the possibility of testing your line of action." Trotsky replies: "This idea is dictated by a purely liberal conception of the course of the revolution. In a period in which all antagonisms assume an open character; and the political struggle swiftly passes into a civil war, the ruling party has sufficient material standard by which to test its line of action, without the possible circulation of Menshevik papers. Noske crushes the Communists, but they grow. We have suppressed the Mensheviks and the S. R. s [Socialist Republics] … and they have disappeared. This criterion is sufficient for us" (p. 101). This is one of the most enlightening theoretical formulations of Bolshevism, from which it appears that the "rightness" of a historical movement or a state is to be judged by whether its use of violence is successful. Noske did not succeed in crushing the German Communists, but Hitler did; it would thus follow from Trotsky’ s rule that Hitler "expressed the interests of historical development". Stalin liquidated the Trotskyists in Russia, and they disappeared – so evidently Stalin, and not Trotsky, stood for historical progress.”

“Teller’s irascible behavior forced him out of the mainstream but not out of the lab, thanks to Oppenheimer who didn’t think we should be without geniuses, even those whose enormous egos caused serious friction. As bright and innovative as Teller was, his overall performance during the war left a lot to be desired. He was not content to be part of a team effort (like yours truly) and preferred to work off to the side on new and different and sometime pretty far-out ideas (like yours truly). This caused considerable resentment. After all there was a war going on and most people thought future nuclear weapon concepts should be worked on sometime in the future, after we had finished our primary assignment. Edward’s behavior was like a colonel on a planning staff during a military campaign who tells his commanding general that he’d like to plan for the next war. That would be the end of the colonel, who would be demoted and shipped off to some base in the Aleutian Islands.
[5]Oppenheimer, however, realized that guys like Teller, despite their shortcomings, were necessary to have around; one never knows when a guy like that can be worth his weight in gold, which to the best of my recollection never happened with Teller. So an arrangement was worked out where Teller and a handful of like-minded theoretical physicists, willing to put up with his domineering ways, formed a small group dedicated to doing what they pleased, realizing their efforts stood precious little chance of impacting on the project.
[5]The one idea dearest to Teller’s heart was the H-bomb. He and a couple of his cronies applied themselves to devising various schemes on designing such a weapon. All of them turned out to be impractical and most of them unworkable. Which never slowed him down in the slightest for reasons we’ll never know nor will he. I’ve known Edward for a very long time and although I’ve never known him well, one thing about him became clear to me from the very beginning: he was a creature possessed. By what? Again, who knows? Many, if not most, who have read about his life and what he has done, plus those who have known him directly and observed him close at hand and at great length, would say by Satan (which has been said all over the world about me). I wouldn’t go along with that and although I have seen Teller give some of the most impassioned statements morally defending his positions, some of which I have found deeply moving and thoroughly convincing, I would not say that the God I’ve been told exists has had a tight hold on him. If Edward has been possessed by anyone it’s been himself. I’d say the same for myself, and I’ve given you some reasons why, but hardly all of them. I don’t know all of them and would be ashamed to tell you if I did.”
