Thomas Samuel Kuhn ( /ˈkuːn/; July 18, 1922 – June 17, 1996) was an American historian and philosopher of science whose controversial 1962 book The Structure of Scientific Revolutions was deeply influential in both academic and popular circles, introducing the term "paradigm shift," which has since become an English-language staple.

Kuhn has made several notable claims concerning the progress of scientific knowledge: that scientific fields undergo periodic "paradigm shifts" rather than solely progressing in a linear and continuous way; that these paradigm shifts open up new approaches to understanding that scientists would never have considered valid before; and that the notion of scientific truth, at any given moment, cannot be established solely by objective criteria but is defined by a consensus of a scientific community. Competing paradigms are frequently incommensurable; that is, they are competing accounts of reality which cannot be coherently reconciled. Thus, our comprehension of science can never rely on full "objectivity"; we must account for subjective perspectives as well.

Life[link]

Thomas Kuhn was born in Cincinnati, Ohio to Samuel L. Kuhn, an industrial engineer, and Minette Stroock Kuhn. He obtained his B.S. degree in physics from Harvard University in 1943, and M.S. and Ph.D. degrees in physics in 1946 and 1949, respectively. As he states in the first few pages of the preface to the second edition of The Structure of Scientific Revolutions, his three years of total academic freedom as a Harvard Junior Fellow were crucial in allowing him to switch from physics to the history (and philosophy) of science. He later taught a course in the history of science at Harvard from 1948 until 1956 at the suggestion of university president James Conant. After leaving Harvard, Kuhn taught at the University of California, Berkeley, in both the philosophy department and the history department, being named Professor of the History of Science in 1961. Kuhn interviewed and taped Danish physicist Niels Bohr the day before Bohr's death.^[1] At Berkeley, he wrote and published (in 1962) his best known and most influential work:^[2] The Structure of Scientific Revolutions. In 1964, he joined Princeton University as the M. Taylor Pyne Professor of Philosophy and History of Science. In 1979, he joined the Massachusetts Institute of Technology (MIT) as the Laurance S. Rockefeller Professor of Philosophy, remaining there until 1991. In 1994, Kuhn was diagnosed with lung cancer, of which he died in 1996.

Thomas Kuhn was married twice, first to Kathryn Muhs (with whom he had three children) and later to Jehane Barton Burns (Jehane R. Kuhn).

[edit] The Structure of Scientific Revolutions

The Structure of Scientific Revolutions (SSR) was originally printed as an article in the International Encyclopedia of Unified Science, published by the logical positivists of the Vienna Circle. In this book, Kuhn argued that science does not progress via a linear accumulation of new knowledge, but undergoes periodic revolutions, also called "paradigm shifts" (although he did not coin the phrase),^[3] in which the nature of scientific inquiry within a particular field is abruptly transformed. In general, science is broken up into three distinct stages. Prescience, which lacks a central paradigm, comes first. This is followed by "normal science", when scientists attempt to enlarge the central paradigm by "puzzle-solving". Guided by the paradigm, normal science is extremely productive: "when the paradigm is successful, the profession will have solved problems that its members could scarcely have imagined and would never have undertaken without commitment to the paradigm."^[4]

During the period of normal science, the failure of a result to conform to the paradigm is seen not as refuting the paradigm, but as the mistake of the researcher, contra Popper's falsifiability criterion. As anomalous results build up, science reaches a crisis, at which point a new paradigm, which subsumes the old results along with the anomalous results into one framework, is accepted. This is termed revolutionary science.

In SSR, Kuhn also argues that rival paradigms are incommensurable—that is, it is not possible to understand one paradigm through the conceptual framework and terminology of another rival paradigm. For many critics, for example David Stove (Popper and After, 1982), this thesis seemed to entail that theory choice is fundamentally irrational: if rival theories cannot be directly compared, then one cannot make a rational choice as to which one is better. Whether Kuhn's views had such relativistic consequences is the subject of much debate; Kuhn himself denied the accusation of relativism in the third edition of SSR, and sought to clarify his views to avoid further misinterpretation. Freeman Dyson has quoted Kuhn as saying "I am not a Kuhnian!",^[5] referring to the relativism that some philosophers have developed based on his work.

The enormous impact of Kuhn's work can be measured in the changes it brought about in the vocabulary of the philosophy of science: besides "paradigm shift", Kuhn popularized the word "paradigm" itself from a term used in certain forms of linguistics and the work of Georg Lichtenberg to its current broader meaning, coined the term "normal science" to refer to the relatively routine, day-to-day work of scientists working within a paradigm, and was largely responsible for the use of the term "scientific revolutions" in the plural, taking place at widely different periods of time and in different disciplines, as opposed to a single "Scientific Revolution" in the late Renaissance. The frequent use of the phrase "paradigm shift" has made scientists more aware of and in many cases more receptive to paradigm changes, so that Kuhn’s analysis of the evolution of scientific views has by itself influenced that evolution.^{[citation needed]}

Kuhn's work has been extensively used in social science; for instance, in the post-positivist/positivist debate within International Relations. Kuhn is credited as a foundational force behind the post-Mertonian Sociology of Scientific Knowledge.

A defense Kuhn gives against the objection that his account of science from The Structure of Scientific Revolutions results in relativism can be found in an essay by Kuhn called "Objectivity, Value Judgment, and Theory Choice."^[6] In this essay, he reiterates five criteria from the penultimate chapter of SSR that determine (or help determine, more properly) theory choice:

1. - Accurate - empirically adequate with experimentation and observation
2. - Consistent - internally consistent, but also externally consistent with other theories
3. - Broad Scope - a theory's consequences should extend beyond that which it was initially designed to explain
4. - Simple - the simplest explanation, principally similar to Occam's razor
5. - Fruitful - a theory should disclose new phenomena or new relationships among phenomena

He then goes on to show how, although these criteria admittedly determine theory choice, they are imprecise in practice and relative to individual scientists. According to Kuhn, "When scientists must choose between competing theories, two men fully committed to the same list of criteria for choice may nevertheless reach different conclusions."^[6] For this reason, the criteria still are not "objective" in the usual sense of the word because individual scientists reach different conclusions with the same criteria due to valuing one criterion over another or even adding additional criteria for selfish or other subjective reasons. Kuhn then goes on to say, "I am suggesting, of course, that the criteria of choice with which I began function not as rules, which determine choice, but as values, which influence it."^[6] Because Kuhn utilizes the history of science in his account of science, his criteria or values for theory choice are often understood as descriptive normative rules (or more properly, values) of theory choice for the scientific community rather than prescriptive normative rules in the usual sense of the word "criteria," although there are many varied interpretations of Kuhn's account of science.

Polanyi–Kuhn debate[link]

Although they used different terminologies, both Kuhn and Michael Polanyi believed that scientists' subjective experiences made science a relativized discipline. Polanyi lectured on this topic for decades before Kuhn published "The Structure of Scientific Revolutions."

Supporters of Polanyi charged Kuhn with plagiarism, as it was known that Kuhn attended several of Polanyi's lectures, and that the two men had debated endlessly over the epistemology of science before either had achieved fame. In response to these critics, Kuhn cited Polanyi in the second edition of "The Structure of Scientific Revolutions,"^[7] and the two scientists agreed to set aside their differences in the hopes of enlightening the world to the dynamic nature of science.^{[citation needed]} Despite this intellectual alliance, Polanyi's work was constantly interpreted by others within the framework of Kuhn's paradigm shifts, much to Polanyi's (and Kuhn's) dismay.^[8]

Honors[link]

Kuhn was named a Guggenheim Fellow in 1954, and in 1982 was awarded the George Sarton Medal by the History of Science Society. He was also awarded numerous honorary doctorates.

Samuel ( /ˈsæm.juː.əl/;^[1] Hebrew: שְׁמוּאֶל, Modern Shmu'el Tiberian Šəmûʼēl; Greek: Σαμουήλ Samouēl; Latin: Samvel; صموئيل, Ṣamu’īl; Strong's: Shemuwel) is a leader of ancient Israel in the Books of Samuel in the Hebrew Bible. He is also known as a prophet and is mentioned in the Qur'an.^[2]

His status, as viewed by rabbinical literature, is that he was the last of the Hebrew Judges and the first of the major prophets who began to prophesy inside the Land of Israel. He was thus at the cusp between two eras. According to the text of the Books of Samuel, he also anointed the first two kings of the Kingdom of Israel: Saul and David.

Biblical account[link]

Gerbrand van den Eeckhout - Hannah presenting her son Samuel to the priest Eli ca.1665

Family[link]

Samuel's mother was Hannah and his father was Elkanah. Hannah, at the beginning of the narrative, is barren and childless, like Abraham's wife Sarah. Hannah prays to God for a child. Eli who is sitting at the foot of the doorpost in the sanctuary at Shiloh, sees her apparently mumbling and thinks Hannah is drunk, but is soon assured of her motivation and sobriety. Eli was, according to the Books of Samuel, the name of a priest of Shiloh, and one of the last Israelite Judges before the rule of kings in ancient Israel. He blesses her after she promises the child to God. Subsequently Hannah becomes pregnant; her child is Samuel. After he is weaned, she leaves him in Eli's care.

Elkanah is Samuel's father and lives at Ramah (1 Sam. 1:19; 2:11; comp. 28:3), in the district of Zuph. His genealogy is also found in a pedigree of the Kohathites (1 Chron. 6:3-15) and in that of Heman, his great-grandson (ib. vi. 18-22). According to the genealogical tables, Elkanah was, a Levite, a fact otherwise not mentioned in the books of Samuel. The fact that Elkanah, a Levite, was denominated an Ephraimite is analogous to the designation of a Levite belonging to Judah (Judges 17:7, for example).^[3]

Name[link]

According to 1 Samuel 1:20, Hannah named Samuel in memory of her requesting a child from God and God listening. Samuel is translated as Heard of God or possibly as a sentence "God has heard" (from 'Shama', heard and 'El', God — with "Shama" as the verb and "El" as the subject).^[4] Samuel in the Hebrew root word is "sha’al" which is mentioned seven times in 1 Samuel 1 and once as "sha’ul" (1:28), which is Saul’s name in Hebrew. Coogan suggests that Saul’s birth narrative was transferred to Samuel by the Deuteronomistic Historians.^[5]

Calling[link]

One night, around the age of 13, Samuel heard a voice calling his name. According to the Jewish historian Josephus, Samuel was about 12 years old.^[6] He initially assumed it was coming from Eli and went to Eli to ask what he wished to say. Eli, however, sent Samuel back to sleep. After this happened three times Eli realized that the voice was God's, and instructed Samuel on how to respond. Once Samuel responded God told him that the wickedness of the sons of Eli had resulted in their dynasty being condemned to destruction. Eli asked Samuel to honestly recount to him what he had been told, and upon receiving the communication merely said that God should do what seems right to himself.

Leader[link]

During Samuel's youth at Shiloh the Philistines inflicted a decisive defeat against the Israelites at Eben-Ezer (1 Sam. 4:1,2), placed the land under Philistine oppression, and took the sanctuary's Ark for themselves. (Some modern textual scholars consider that the Song of Moses, believed to be originally distinct from the surrounding text of Deuteronomy and not written by Moses, may in reality have been written in response to the theological implications of this disastrous defeat, possibly by Samuel himself.)^{[citation needed]}

This was decades before the Israelites began to be ruled by a king. After 20 years of such oppression, Samuel, who had gained national prominence as a prophet, summoned the people to Mizpah (one of the highest hills in the land), where he organized them into an army, and led them against the Philistines. The Philistines, having marched to Mizpah to attack the newly amassed Israelite army, were soundly defeated and fled in terror. The retreating Philistines were slaughtered by the Israelites, which the Bible portrays positively. The text then states that Samuel erected a large stone at the battle site as a memorial, and there ensued a long period of peace thereafter.

Textual criticism[link]

National prophet, local seer[link]

Some authors see the biblical Samuel as combining descriptions of two distinct roles:

• A seer, based at Ramah, and seemingly known scarcely beyond the immediate neighbourhood of Ramah (Saul, for example, not having heard of him, with his servant informing him of his existence instead). In this role, Samuel is associated with the bands of musical ecstatic roaming prophets (shouters - neb'im) at Gibeah, Bethel, and Gilgal, and some traditional scholars have argued that Samuel was the founder of these groups. At Ramah, Samuel secretly anoints Saul, after having met him for the first time, while Saul was looking for his father's lost donkeys, and treated him to a meal.
• A prophet, based at Shiloh, who went throughout the land, from place to place, with unwearied zeal, reproving, rebuking, and exhorting the people to repentance. In this role, Samuel acted as a (biblical) judge, publicly advising the nation, and also giving private advice to individuals. Eventually Samuel delegates this role to his sons, based at Beersheba, but they behave corruptly and so the people, facing invasion from the Ammonites, persuade Samuel to appoint a king. Samuel reluctantly does so, and anoints Saul in front of the entire nation, who had gathered to see him.

Textual scholars suggest that these two roles come from different sources, which later were spliced together to form the Book(s) of Samuel. The oldest is considered to be that which marks Samuel as the local seer of Ramah, who willingly anoints Saul as King in secret, while the latter is that which presents Samuel as a national figure, who begrudgingly anoints Saul as King in front of a national assembly. This later source is generally known as the republican source, since here, and elsewhere, it denigrates the actions and role of the monarchy (particularly those of Saul) and favours religious figures, in contrast to the other main source – the monarchial source – which treats the monarchy favourably. Theoretically if we had the monarchial source we would see Saul appointed king by public acclamation, due to his military victories, and not by cleromancy involving Samuel. Another difference between the sources is that the republican source treats the shouters as somewhat independent from Samuel (1 Samuel 9) rather than having been led by him (1 Samuel 19:18ff). The passage (1 Samuel 7:15-16) in which Samuel is described as having exercised the functions of a (biblical) judge, during an annual circuit from Ramah to Bethel to Gilgal (the Gilgal between Ebal and Gerizim) to Mizpah and back to Ramah, is thought by textual scholars to be a redaction aimed at harmonizing the two portrayals of Samuel.^[7]

The Book(s) of Samuel variously describe Samuel as having carried out sacrifices at sanctuaries, and having constructed and sanctified altars. According to the Mitzvot only Aaronic priests and/or Levites (depending on the Mitzvah) were permitted to perform these actions, and simply being a nazarite or prophet was insufficient. The books of Samuel and Kings offer numerous examples where this rule is not followed by kings and prophets, but some textual scholars look elsewhere seeking a harmonization of the issues. In the Book of Chronicles, Samuel is described as a Levite, rectifying this situation; however textual scholars widely see the Book of Chronicles as an attempt to redact the Book(s) of Samuel and of Kings to conform to later religious sensibilities. Since many of the Mitzvot themselves are thought to postdate the Book(s) of Samuel (according to the documentary hypothesis), Chronicles is probably making its claim based on religious bias. The Levitical genealogy of 1 Chronicles 4 is not historical, according to modern scholarship.^[7]

The Deuteronomistic Historians' Portrait of Samuel[link]

The Deuteronomistic Historians, who redacted the Former Prophets (Joshua, Judges, 1 & 2 Samuel, 1 & 2 Kings), idealized Samuel as a figure who is larger than life like Joshua. Samuel is a priest even though he is not of the tribe of Levi from his childhood. Samuel is a judge who leads the military like in the Book of Judges and also who exercises judicial functions. In 1 Sam 12:6-17, the Deuteronomic Historians composed a speech of Samuel that puts him as the judge sent by God to save Israel.^[8] In 1 Samuel 9:6-20, Samuel is seen as a local “seer.” The Deuteronomistic Historians preserved this view of Samuel while contributing him as “the first of prophets to articulate the failure of Israel to live up to its covenant with God.” ^[8] For the Deuteronomistic Historians, Samuel was extension of Moses and continuing Moses’ function as a prophet, judge, and a priest which made historical Samuel uncertain.^[8]

Samuel's retirement and death[link]

Apparition of the spirit of Samuel to Saul, by Salvator Rosa, 1668.

Samuel initially appointed his two sons as his successors; however, the Israelites rejected them and insisted on having a king rule over them. Samuel, who is opposed to a king, warns them of the potential negative consequences of such a decision, but at the people's insistence, asks God for a king. Samuel is told to seek out Saul, an animal herder said to be a head taller than his peers, and anoint him as the first King of Israel.

Just before his retirement, Samuel gathered the people to an assembly at Gilgal, and gives them a farewell speech, in which he emphasised how prophets and judges were more important than kings, how kings should be held to account, and how the people should not fall into idol worship, or worship of Asherah or of Baal; Samuel threatened that God would subject the people to foreign invaders should they disobey. This is seen by some people as a deuteronomic redaction;^[7] being that archaeologically sees that Asherah was still worshipped in Israelite households well into the 6th century. However, the Bible is clear in 1 Kings 11:5, 33, and 2 Kings 23:13 that the Israelites fell into Asherah worship later on.^[9]

Samuel then went into retirement, though he reappears briefly in the two accounts of why Saul's dynasty lost divine favour (parts of 1 Samuel 13 and 15), essentially acting, according to scholars, as the narrator's mouthpiece.^{[citation needed]} Apart from being the individual who anoints David as king, a role Samuel is abruptly summoned to take, he does not appear any further in the text until his own death at his hometown Ramah (1 Samuel 25:1, 28:3), where he is buried (cf. 2 Kings 21:18, 2 Chronicles 33:20, and John 19:41). According to classical rabbinical sources, this was at the age of fifty-two.

Samuel's death, however, is not completely the end of his appearance in the narrative. In the passage concerning Saul's visit to the Witch of Endor, ascribed by textual scholars to the republican source, Samuel was temporarily raised from the dead so that he can tell Saul his future. Many Christian interpretations of this event portray Samuel's appearance as being a deception from Satan, or even a demon in disguise. There are other interpretations which say that Saul and the witch having been frightened by his appearance, and Samuel as having been composed, classical rabbinical sources argue that Samuel was terrified by the ordeal, having expected to be appearing to face God's judgement, and had therefore brought Moses with him (to the land of the living) as a witness to his adherence to the mitzvot.^[7]

Perspectives on Samuel[link]

Judaism[link]

According to the Book of Jeremiah, and one of the Psalms (99), Samuel had a high devotion to God. Classical Rabbinical literature adds that he was more than an equal to Moses, God speaking directly to Samuel, rather than Samuel having to attend the tabernacle to hear God.^[10] Samuel is also described by the Rabbis as having been extremely intelligent; he argued that it was legitimate for laymen to slaughter sacrifices, since the Halakha only insisted that the priests bring the blood (cf Leviticus 1:5, Zebahim 32a).^[11] Eli, who was viewed negatively by many Classical Rabbis, is said to have reacted to this logic of Samuel by arguing that it was technically true, but Samuel should be put to death for making legal statements while Eli (his mentor) was present.^[11]

Samuel is also treated by the Classical Rabbis as a much more sympathetic character than he appears at face value in the Bible; his annual circuit is explained as being due to his wish to spare people the task of having to journey to him; Samuel is said to have been very rich, taking his entire household with him on the circuit so that he didn't need to impose himself on anyone's hospitality; when Saul fell out of God's favour, Samuel is described as having grieved copiously and having prematurely aged.^[12]

Christianity[link]

For Evangelical Christians Samuel is considered to be a Prophet, Judge, and wise Leader of Israel, and treated as an example of fulfilled commitments to God. On the Eastern Orthodox liturgical calendar, his feast day is August 20. He is commemorated as one of the Holy Forefathers in the Calendar of Saints of the Armenian Apostolic Church on July 30. In the Coptic Orthodox Church, the commemoration of the departure of Samuel the Prophet is celebrated on 9 Paoni.

Islam[link]

Mosque of the Prophet Samuel, Jerusalem

Tomb of the Prophet Samuel, Jerusalem

Samuel is also a revered prophet^[13] and seer in the Islamic faith. The narrative of Samuel in Muslim literature focuses specifically on his birth and the anointing of Saul. Other elements from his narrative are in accordance with the narratives of other prophets of Israel, as exegesis recounts Samuel's preaching against idolatry. Although he is mentioned in the Qur'an, his name is not given but he is instead referred to as "a Prophet".^[14] According to Islamic history, the Israelites, after the time of the prophet Moses, wanted a king to rule over their country. Thus, God sent the prophet Samuel to anoint Saul as the first king for the Israelites. The Qur'an states:

Have you thought of the elders of Israel after Moses, and how they said to their apostle: "Set up a king for us, then we shall fight in the way of God?" He replied: "This too is possible that when commanded to fight you may not fight at all." They said: "How is it we should not fight in the way of God when we have been driven from our homes and deprived of our Sons?" But when they were ordered to fight they turned away, except for a few; yet God knows the sinners.

—Qur'an, sura 2 (Al-Baqara), ayah 246^[14]

The Qur'an goes on to state that a king was anointed by the prophet, whose name was Talut (Saul in the Hebrew Bible). However, it states that the Israelites mocked and reviled the newly appointed king, as he was not wealthy from birth. But, in sharp contrast to the Hebrew Bible, the Qur'an praises Saul greatly, and mentions that he was gifted with great spiritual and physical strength. In the Qur'anic account, Samuel prophesies to the children of Israel, telling them that the sign of Saul's kingship will be that the Ark of the Covenant will come back to the Israelites:

And when their prophet said to them: "God has raised Saul king over you," they said: "How can he be king over us when we have greater right to kingship than he, for he does not even possess abundant wealth?" "God has chosen him in preference to you," said the prophet "and gifted him abundantly in wisdom and stature; and God gives authority to whomsoever He will: God is infinite and all-wise."
Their prophet said to them: "The sign of his kingship will be that you will come to have a chest (tabu't) full of peace and tranquility (Sakina) from your Lord and remainder of the legacy of the children of Moses and the children of Aaron, carried over by the angels. In this certainly shall be a sign for you if you really believe."

—Qur'an, sura 2 (Al-Baqara), ayah 247–248^[15]

Sir Karl Raimund Popper, CH FRS^[1] FBA (28 July 1902 – 17 September 1994) was an Austro-British^[2] philosopher and professor at the London School of Economics.^[3] He is generally regarded as one of the greatest philosophers of science of the 20th century;^[4][5] he also wrote extensively on social and political philosophy.

Popper is known for his attempt to repudiate the classical observationalist/inductivist form of scientific method in favour of empirical falsification. He is also known for his opposition to the classical justificationist account of knowledge which he replaced with critical rationalism, "the first non justificational philosophy of criticism in the history of philosophy".^[6] In political discourse, he is known for his vigorous defence of liberal democracy and the principles of social criticism that he came to believe made a flourishing "open society" possible.

Personal life[link]

Karl Popper was born in Vienna (then in Austria-Hungary) in 1902, to upper middle-class parents. All of Karl Popper's grandparents were Jewish, but the Popper family converted to Lutheranism before Karl was born.^[7] Karl's father Simon Siegmund Carl Popper was a lawyer from Bohemia, and mother Jenny Schiff was of Silesian and Hungarian descent. After establishing themselves in Vienna, the Poppers made a rapid social climb in Viennese society: Simon Siegmund Carl became a legal partner^{[clarification needed]} of Vienna's liberal mayor Raimond Grübl and, after his death in 1898, took over the firm (Karl received his middle name from the mayor).^[7]

Popper received a Lutheran upbringing and was educated at the University of Vienna.^[8] His father was a doctor of law at the Vienna University and a bibliophile who had 12,000–14,000 volumes in his personal library.^[9] Popper inherited both the library and the disposition from him.^[10]

In 1919, Popper became attracted by Marxism and subsequently joined the Association of Socialist School Students. He also became a member of the Social Democratic Workers' Party of Austria, which was at that time a party that fully adopted the Marxist ideology.^[11] After the June 15, 1919 street battle in the Hörlgasse, when police shot eight of his unarmed party comrades, he became disillusioned by what he saw to be the pseudo-scientific historical materialism of Marx, abandoned the ideology, and remained a supporter of social liberalism throughout his life.
