“The reciprocal relationship of epistemology and science is of noteworthy kind. They are dependent on each other. Epistemology without contact with science becomes an empty scheme. Science without epistemology is — insofar as it is thinkable at all — primitive and muddled. However, no sooner has the epistemologist, who is seeking a clear system, fought his way through to such a system, than he is inclined to interpret the thought-content of science in the sense of his system and to reject whatever does not fit into his system. The scientist, however, cannot afford to carry his striving for epistemological systematic that far. He accepts gratefully the epistemological conceptual analysis; but the external conditions, which are set for him by the facts of experience, do not permit him to let himself be too much restricted in the construction of his conceptual world by the adherence to an epistemological system. He therefore must appear to the systematic epistemologist as a type of unscrupulous opportunist: he appears as realist insofar as he seeks to describe a world independent of the acts of perception; as idealist insofar as he looks upon the concepts and theories as free inventions of the human spirit (not logically derivable from what is empirically given); as positivist insofar as he considers his concepts and theories justified only to the extent to which they furnish a logical representation of relations among sensory experiences. He may even appear as Platonist or Pythagorean insofar as he considers the viewpoint of logical simplicity as an indispensible and effective tool of his research.”

“As all human rights derive from human dignity, it is important to recognize that human dignity is not a product of positivism but an expression of natural law and human rationality. Although an abstract concept, human dignity has engendered concrete norms of human rights, a practical mode d’emploi strengthened by enforcement mechanisms.”

“Smith’s own theory, as given in the first five editions, is for the most part a theory of moral judgement —that is to say, it is an answer to the second question set out in the initial description of the subject of philosophical ethics. […] There is no thoroughgoing inquiry of what constitutes the character of virtue, as required by the first of the two questions, even though the historical survey at the end of the book deals with both questions in turn and, as it happens, gives more space to the first topic, the character of virtue, than to the second, the nature of moral judgement.
The fact is that Smith did not reach a distinctive view on the first topic. He has a distinctive view of the content of virtue, that is to say, a view of what are the cardinal virtues; but he does not give us an explanation of what is meant by the concept of moral virtue, how it arises, how it differentiates moral excellence from other forms of human excellence. […] I think that, when Smith came to revise the work for the sixth edition, he realized that he had not dealt at all adequately with the first of the two questions, and for that reason he added the new part VI, entitled ‘Of the Character of Virtue’, to remedy the omission. It is not, in my opinion, an adequate remedy, and it certainly does not match Smith’s elaborate answer to the second question. […]
Since the second of the two topics, the nature of moral judgement, is the main subject of both versions of Smith’s book, I shall give it priority in what follows. There is in fact a clear development in Smith’s view of this topic, especially in his conception of the impartial spectator, the most important element of Smith’s ethical theory.”

“We know by actual observation only a comparatively small part of the whole universe. I will call this "our neighborhood." Even within the confines of this province our knowledge decreases very rapidly as we get away from our own particular position in space and time. It is only within the solar system that our empirical knowledge extends to the second order of small quantities (and that only for g44 and not for the other gαβ), the first order corresponding to about 10-8. How the gαβ outside our neighborhood are, we do not know, and how they are at infinity of space or time we shall never know. Infinity is not a physical but a mathematical concept, introduced to make our equations more symmetrical and elegant. From the physical point of view everything that is outside our neighborhood is pure extrapolation, and we are entirely free to make this extrapolation as we please to suit our philosophical or aesthetical predilections—or prejudices. It is true that some of these prejudices are so deeply rooted that we can hardly avoid believing them to be above any possible suspicion of doubt, but this belief is not founded on any physical basis. One of these convictions, on which extrapolation is naturally based, is that the particular part of the universe where we happen to be, is in no way exceptional or privileged; in other words, that the universe, when considered on a large enough scale, is isotropic and homogeneous.”

“I see the expression of… economy clearly in the gradual reduction of the statical laws of machines to a single one, viz., the principle of virtual work: in the replacement of Kepler's laws by Newton's single law… and in the [subsequent] reduction, simplification and clarification of the laws of dynamics. I see clearly the biological-economical adaptation of ideas, which takes place by the principles of continuity (permanence) and of adequate definition and splits the concept 'heat' into the two concepts of 'temperature' and 'quantity of heat'; and I see how the concept 'quantity of heat' leads on to 'latent heat', and to the concepts of 'energy' and 'entropy.”

“An examination of our terms, such as competition, rivalry, emulation, etc., reveals that the traditional perspective remains inscribed in the language. Competitors are fundamentally those who run or walk together, rivals who dwell on opposite banks of the same river, etc…The modern view of competition and conflict is the unusual and exceptional view, and our incomprehension is perhaps more problematic than the phenomenon of primitive prohibition. Primitive societies have never shared our conception of violence. For us, violence has a conceptual autonomy, a specificity that is utterly unknown to primitive societies. We tend to focus on the individual act, whereas primitive societies attach only limited importance to it and have essentially pragmatic reasons for refusing to isolate such an act from its context. This context is one of violence. What permits us to conceive abstractly of an act of violence and view it as an isolated crime is the power of a judicial institution that transcends all antagonists. If the transcendence of the judicial institution is no longer there, if the institution loses its efficacy or becomes incapable of commanding respect, the imitative and repetitious character of violence becomes manifest once more; the imitative character of violence is in fact most manifest in explicit violence, where it acquires a formal perfection it had not previously possessed. At the level of the blood feud, in fact, there is always only one act, murder, which is performed in the same way for the same reasons in vengeful imitation of the preceding murder. And this imitation propagates itself by degrees. It becomes a duty for distant relatives who had nothing to do with the original act, if in fact an original act can be identified; it surpasses limits in space and time and leaves destruction everywhere in its wake; it moves from generation to generation. In such cases, in its perfection and paroxysm mimesis becomes a chain reaction of vengeance, in which human beings are constrained to the monotonous repetition of homicide. Vengeance turns them into doubles.”

“Who is, in the classical conception, the subject that comprehends the ontological condition of truth and untruth? It is the master of pure contemplation (theoria), and the master of a practice guided by theoria, i. e., the philosopher-statesman. To be sure, the truth which he knows and expounds is potentially accessible to everyone. Led by the philosopher, the slave in Plato’s Meno is capable of grasping the truth of a geometrical axiom, i. e., a truth beyond change and corruption. But since truth is a state of Being as well as of thought, and since the latter is the expression and manifestation of the former, access to truth remains mere potentiality as long as it is not living in and with the truth. And this mode of existence is closed to the slave — and to anyone who has to spend his life procuring the necessities of life. Consequently, if men no longer had to spend their lives in the realm of necessity, truth and a true human existence would be in a strict and real sense universal. Philosophy envisages the equality of man but, at the same time, it submits to the factual denial of equality. For in the given reality, procurement of the necessities is the life-long job of the majority, and the necessities have to be procured and served so that truth (which is freedom from material necessities) can be. Here, the historical barrier arrests and distorts the quest for truth; the societal division of labor obtains the dignity of an ontological condition. If truth presupposes freedom from toil, and if this freedom is, in the social reality, the prerogative of a minority, then the reality allows such a truth only in approximation and for a privileged group. This state of affairs contradicts the universal character of truth, which defines and “prescribes” not only a theoretical goal, but the best life of man qua man, with respect to the essence of man. For philosophy, the contradiction is insoluble, or else it does not appear as a contradiction because it is the structure of the slave or serf society which this philosophy does not transcend. Thus it leaves history behind, unmastered, and elevates truth safely above the historical reality. There, truth is reserved intact, not as an achievement of heaven or in heaven, but as an achievement of thought — intact because its very notion expresses the insight that those who devote their lives to earning a living are incapable of living a human existence.”

“As a metaphor - and I stress that it is intended as a metaphor - the concept of an invariant that arises out of mutually or cyclically balancing changes may help us to approach the concept of self. In cybernetics this metaphor is implemented in the ‘closed loop’, the circular arrangement of feedback mechanisms that maintain a given value within certain limits. They work toward an invariant, but the invariant is achieved not by a steady resistance, the way a rock stands unmoved in the wind, but by compensation over time. Whenever we happen to look in a feedback loop, we find the present act pitted against the immediate past, but already on the way to being compensated itself by the immediate future. The invariant the system achieves can, therefore, never be found or frozen in a single element because, by its very nature, it consists in one or more relationships - and relationships are not in things but between them.
If the self, as I suggest, is a relational entity, it cannot have a locus in the world of experiential objects. It does not reside in the heart, as Aristotle thought, nor in the brain, as we tend to think today. It resides in no place at all, but merely manifests itself in the continuity of our acts of differentiating and relating and in the intuitive certainty we have that our experience is truly ours.”

“In the appreciation of a work of art or an art form, consideration of the receiver never proves fruitful. Not only is any reference to a particular public or its representatives misleading, but even the concept of an "ideal" receiver is detrimental in the theoretical consideration of art, since all it posits is the existence and nature of man as such. Art, in the same way, posits man's physical and spiritual existence, but in none of its works is it concerned with his attentiveness. No poem is intended for the reader, no picture for the beholder, no symphony for the audience.”

Walter Benjamin (1892–1940) German literary critic, philosopher and social critic (1892-1940)

Nirgends erweist sich einem Kunstwerk oder einer Kunstform gegenüber die Rücksicht auf den Aufnehmenden für deren Erkenntnis fruchtbar. Nicht genug, dass jede Beziehung auf ein bestimmtes Publikum oder dessen Repräsentanten vom Wege abführt, ist sogar der Begriff eines "idealen" Aufnehmenden in allen kunsttheoretischen Erörterungen vom Übel, weil diese lediglich gehalten sind, Dasein und Wesen des Menschen überhaupt vorauszusetzen. So setzt auch die Kunst selbst dessen leibliches und geistiges Wesen voraus—seine Aufmerksamkeit aber in keinem ihrer Werke. Denn kein Gedicht gilt dem Leser, kein Bild dem Beschauer, keine Symphonie der Hörerschaft.

“So, is “Caliph Ibrahim” of the Islamic State an extremist, a militant, a terrorist or an Islamic fighter? None of the above. All those labels imply behavior that makes some sort of sense in terms of human reality and normal ideologies. Yet the Islamic State and its kindred have broken out of the entire conceivable range of political activity, even its extreme forms. A “militant” spends much of his time promoting an idea or a political program within acceptable rules of behavior. The neo-Islamists, by contrast, recognize no rules apart from those they themselves set; they have no desire to win an argument through hard canvassing. They don’t even seek to impose a point of view; they seek naked and brutal domination. A “terrorist,” meanwhile, tries to instill fear in an adversary from whom he demands specific concessions. Yet the Islamic State et al. use mass murder to such ends. They don’t want to persuade or cajole anyone to do anything in particular; they want everything. “Islamic fighter” is equally inapt. An Islamic fighter is a Muslim who fights a hostile infidel who is trying to prevent Muslims from practicing their faith. That was not the situation in Mosul. No one was preventing the city’s Muslim majority from practicing their faith, let alone forcing them to covert to another religion. Yet the Islamic State came, conquered and began to slaughter. The Islamic State kills people because it can. And in both Syria and Iraq it has killed more Muslims than members of any other religious community. How, then, can we define a phenomenon that has made even al Qaeda, the Taliban and the Khomeinist gangs appear “moderate” in comparison? The international community faced a similar question in the 18th century when pirates acted as a law onto themselves, ignoring the most basic norms of human interaction. The issue was discussed in long negotiations that led to the Treaty of Utrecht (1713) and the Treaty of Rastadt (1714) and developed a new judicial concept: the crime against humanity. Those who committed that crime would qualify as “enemies of mankind” — in Latin, hostis generis humanis. Individuals and groups convicted of such a crime were no longer covered by penal codes or even the laws of war. They’d set themselves outside humanity by behaving like wild beasts… Neo-Islamist groups represent a cocktail of nihilism and crimes against humanity. Like the pirates of yesteryear, they’ve attracted criminals from many different nationalities… Having embarked on genocide, the neo-Islamists do not represent an Iraqi or Syrian or Nigerian problem, but a problem for humanity as a whole. They are not enemies of any particular religion, sect or government but enemies of mankind. They deserve to be treated as such (as do the various governments and semi-governmental “charities” that help them). To deal with these enemies of mankind, we need much more than frozen bank accounts and visa restrictions.”

“Yet even here all these peoples have remained rooted in their sacred homelands for centuries. Though oppressed and colonized by outsiders, they have never been expelled en masse, and so the theme of restoration to the homeland has played little part in the conceptions of these peoples. There are, however, two peoples, apart from the Jews, for whom restoration of the homeland and commonwealth have been central: the Greeks and the Armenians, and together with the Jews, they constitute the archetypal Diaspora peoples, or what John Armstrong has called ‘mobilized diasporas° Unlike diasporas composed of recent mi migrant workers—Indians, Chinese and others in Southeast Asia, East Africa and the Caribbean— mobilized diasporas are of considerable antiquity, are generally polyglot and multi-skilled trading communities and have ancient, portable religious traditions. Greeks, Jews, and Armenians claimed an ancient homeland and kingdom, looked back nostalgically to a golden age or ages of great kings, saints, sages and poets, yearned to return to ancient capitals with sacred sites and buildings, took with them wherever they went their ancient scriptures, sacred scripts and separate liturgies, founded in every city congregations with churches, clergy and religious schools, traded across the Middle East and Europe using the networks of enclaves of their co-religionists to compete with other ethnic trading networks, and used their wealth, education and economic skills to offset their political powerlessness)”

“Physiologic facts concerning the origin of species in nature were unknown in the time of Darwin... The experience of the breeders was quite inadequate to the use which Darwin made of it. It was neither scientific, nor critically accurate. Laws of variation were barely conjectured; the different types of variability were only imperfectly distinguished. The breeders' conception was fairly sufficient for practical purposes, but science needed a clear understanding of the factors in the general process of variation. Repeatedly Darwin tried to formulate these causes, but the evidence available did not meet his requirements.
Quetelet's law of variation had not yet been published. Mendel's claim of hereditary units for the explanation of certain laws of hybrids discovered by him, was not yet made. The clear distinction between spontaneous and sudden changes, as compared with the ever-present fluctuating variations, is only of late coming into recognition by agriculturists. Innumerable minor points which go to elucidate the breeders' experience, and with which we are now quite familiar, were unknown in Darwin's time. No wonder that he made mistakes, and laid stress on modes of descent, which have since been proved to be of minor importance or even of doubtful validity.”

“The concept of communication includes all of those processes by which people influence one another… This definition is based on the premise that all actions and events have communicative aspects, as soon as they are perceived by a human being; it implies, furthermore, that such perception changes the information which an individual processes and therefor influences him.”

“The main objection to the theory of pure visualization is our thesis that the non-Euclidean axioms can be visualized just as rigorously if we adjust the concept of congruence. This thesis is based on the discovery that the normative function of visualization is not of visual but of logical origin and that the intuitive acceptance of certain axioms is based on conditions from which they follow logically, and which have previously been smuggled into the images. The axiom that the straight line is the shortest distance is highly intuitive only because we have adapted the concept of straightness to the system of Eucidean concepts. It is therefore necessary merely to change these conditions to gain a correspondingly intuitive and clear insight into different sets of axioms; this recognition strikes at the root of the intuitive priority of Euclidean geometry. Our solution of the problem is a denial of pure visualization, inasmuch as it denies to visualization a special extralogical compulsion and points out the purely logical and nonintuitive origin of the normative function. Since it asserts, however, the possibility of a visual representation of all geometries, it could be understood as an extension of pure visualization to all geometries. In that case the predicate "pure" is but an empty addition, since it denotes only the difference between experienced and imagined pictures, and we shall therefore discard the term "pure visualization."”
