Name, Last name : Sezen Altuğ Signature : iii ABSTRACT THE HEURISTIC ROLE OF QUESTIONS IN THE FORMATION OF RESEARCH PROGRAMMES: COPERNICUS’S HELIOCENTRIC SYSTEM Altuğ, Sezen M.A., Department of Philosophy Supervisor: Assoc. Prof. Dr. Samet Bağçe September 2016, 96 pages The aim of this thesis is to develop a critical view about the notion of the heuristic in Lakatos’s methodology of research programmes. The heuristic is tried to be sterilized from its defects with an insight derived from different forms of theories dealing with questions. For that reason, a short survey which includes Socratic dialogues, Hintikka’s theory of interrogative games, van Fraassen’s theory of why-questions, and Laudan’s analogy between science and problem-solving activity is introduced. As a result, the heuristic is construed as the interrogative tools that an inquirer has to construct her theories and solve their problems. The Copernican Revolution is endeavoured to be reconstructed as a case study in the lights of the questions that Copernicus might pose to discover his heliocentric cosmology. Since the Copernican programme cannot be reduced to the theories of Copernicus alone, only the primitive form of this programme which could be associated with Copernicus is examined to check the verity of this newly formulated definition of the heuristic. Keywords: questions, interrogative theory, heuristic, research programmes, Copernicus iv ÖZ ARAŞTIRMA PROGRAMLARININ OLUŞUMUNDA SORULARIN HÖRİSTİK ROLÜ: KOPERNİK’İN GÜNEŞ-MERKEZLİ SİSTEMİ Altuğ, Sezen Yüksek Lisans, Felsefe Bölümü Tez Yöneticisi: Doç. Dr. Samet Bağçe Eylül 2016, 95 sayfa Bu tezin amacı, Lakatos’un araştırma programları metodolojisindeki höristik kavramına dair eleştirel bir bakış açısı geliştirmektir. Sorularla uğraşan farklı teorilerden türetilen bir görüyle höristik, kusurlarından arındırılmaya çalışılmaktadır. Bu gerekçeyle, Sokratik diyaloglar, Hintikka’nın sorgulayıcı oyunlarını, van Fraassen’ın niçin-soruları teorisini ve Laudan’ın bilim ve problem çözme aktivitesi arasında kurduğu benzetmeyi içeren küçük bir inceleme sunulmaktadır. Sonuç olarak höristik, bir araştırmacının teorilerini kurmak ve problemlerini çözmek üzere sahip olduğu sorgulayıcı araçlar olarak tanımlanmaktadır. Kopernik Devrimi ise güneş-merkezli kozmolojinin keşfi için Kopernik’in sormuş olabileceği sorular ışığında yeniden inşa edilmeye uğraşılmaktadır. Kopernikçi programın tek başına Kopernik’in teorilerine indirgenemeyişinden ötürü, programın Kopernik ile ilişkilendirilebilecek yalnızca ilkel bir formu, höristiğe dair yeni formüle edilen tanımın doğruluğunu kontrol etmek için sınanmıştır. Anahtar Kelimeler: sorular, sorgulayıcı teori, höristik, araştırma programları, Kopernik v Let no one untrained in philosophy enter here. vi ACKNOWLEDGMENTS In spite of many difficulties, this thesis has been completed. I owe my gratitude to all lovely people who made this work possible. My deepest gratitude is to my family, without whose encouragement I cannot declare myself as a master in such a challenging discipline. The values that my mother, father, and big sister have brought into my life cannot be limited to these finite lines of acknowledgments. I would like to thank my supervisor Samet Bağçe, for his patience to answer my endless questions, his effort to regiment my disorganized studies, and each bits of his precious time which was spared for me for any reason. Special thanks to my colleagues in the Laboratory for Computational Ontology, especially to my principal investigator, Aziz Fevzi Zambak, for their support. Without them, I would have lost my enthusiasm for philosophy. Also sincere thanks to my friend, Ayça Müge Sevinç, for her motivation to join me in my little trips from Kızılay to METU in weekdays and her joy which never fades. Lastly, I would like to express my heartfelt gratitude to my fiancé, Utku Barış Bektaş, who is always be there for me and helps me to a better person. I am very lucky to have such a person who keeps reminding me that even our darkest moments point the way to a brighter future. vii TABLE OF CONTENTS PLAGIARISM………………………………………………………………………… iii ABSTRACT…………………………………………………………………………. iv ÖZ……………………………………………………………………………………. v DEDICATION………………………………………………………………………… vi ACKNOWLEDGMENTS ……………………………………………………………. vii TABLE OF CONTENTS…………………………………………………………….. viii CHAPTER 1.

TEZ FOTOKOPİSİ İZİN FORMU………………………………………… 95 ix CHAPTER 1 INTRODUCTION Reasoning via questions is a practice employed by many figures in the history of philosophy and science. Most philosophers and scientists have utilized questions deliberately or unintentionally, and been assisted by them in discovering new paths to consider for their inquiries. While the questions preoccupied with “meaning” are mostly associated with philosophical activities, questions pointing a “world-fact” are assumed to be asked by a scientific interest (Uygur, 1964, p.72).1 In this separation, scientific inquiry is depicted as an attempt to interpret the world by examining the fact, whereas philosophical inquiry is treated as a concern about the meaning of definite words, rather than realities going beyond these words in question. Although both of them can deal with the same phenomena, the way of how these two types of inquiry handle the questioned phenomena alters. While scientific questions have recourse to the phenomena of words and are exhausted on the world, philosophical questions look into this phenomena-through-language and are exhausted within the realm of language (Uygur, 1964, pp.77-80). In terms of the form of questioning, the philosophical interrogation is tended to be characterized by the question-pattern of “what-is”, but the inquisitive act of the scientists is usually exemplified by “how” questions (Uygur, 1964, p.78). For instance, “What is the meaning of world?” is a philosophical question, but “How is the world made up?” is a scientific question. 1 Uygur also refers here to the ordinary sense of questioning the world-fact in everyday deeds such as asking the number of rooms by pointing out a particular house. However, such a mundane practice of questioning is out of the topic of this paper. 1 When we go back in history and research the primitive forms of interrogative reasoning, we firstly encounter with the philosophical questions in the form of “what- is”. This type of inquiries mostly resembles the pattern that is followed by the question- and-answer dialogues. This simple form of interrogation performed between two parties aims to get an answer to big (principal) questions through directing smaller (operative) questions to the opponent (Hintikka, 1999, p.67). Platonic or Socratic dialogues are competent examples of this kind of reasoning whose formal structure imitates what two human speakers do in a conversation in everyday life. Of course, the content of the Greek example is much more philosophical. Basically, Socratic method adopts stimulating one‟s thoughts by a question-and-answer dialogue, and aims to demonstrate the inconsistency within one‟s most fundamental opinions. Acknowledging the standard interpretation, a typical Socratic dialogue begins with a question searching for a definition such as “What is X?” The basic rationale behind the Socratic Method is, gradually, making one‟s “indigested opinions” examined,

  • Nicolaus Copernicus: the Loss of Centrality
    I Nicolaus Copernicus: The Loss of Centrality The mathematician who studies the motions of the stars is surely like a blind man who, with only a staff to guide him, must make a great, endless, hazardous journey that winds through innumerable desolate places. [Rheticus, Narratio Prima (1540), 163] 1 Ptolemy and Copernicus The German playwright Bertold Brecht wrote his play Life of Galileo in exile in 1938–9. It was first performed in Zurich in 1943. In Brecht’s play two worldviews collide. There is the geocentric worldview, which holds that the Earth is at the center of a closed universe. Among its many proponents were Aristotle (384–322 BC), Ptolemy (AD 85–165), and Martin Luther (1483–1546). Opposed to geocentrism is the heliocentric worldview. Heliocentrism teaches that the sun occupies the center of an open universe. Among its many proponents were Copernicus (1473–1543), Kepler (1571–1630), Galileo (1564–1642), and Newton (1643–1727). In Act One the Italian mathematician and physicist Galileo Galilei shows his assistant Andrea a model of the Ptolemaic system. In the middle sits the Earth, sur- rounded by eight rings. The rings represent the crystal spheres, which carry the planets and the fixed stars. Galileo scowls at this model. “Yes, walls and spheres and immobility,” he complains. “For two thousand years people have believed that the sun and all the stars of heaven rotate around mankind.” And everybody believed that “they were sitting motionless inside this crystal sphere.” The Earth was motionless, everything else rotated around it. “But now we are breaking out of it,” Galileo assures his assistant.

However, evidence to the contrary suggests that judicial astrology not only continued but actually expanded during the sixteenth and early seventeenth centuries. During this time period, judicial astrologers accomplished this by appropriating contemporary science and mathematics.

Then we describe how, after Kepler’s Astronomia Nova of 1609 and the first telescopic observations by Galileo, it was in the south of France that the New Astronomy found its main promotors with humanists and « amateurs écairés », Nicolas-Claude Fabri de Peiresc and Pierre Gassendi. The professional astronomer Jean-Dominique Cassini, also from Provence, would later elevate the field to new heights in Paris.

Rheticus was one of the first scholars to disseminate the heliocentric theory of Nicolaus Copernicus, according to which the sun—in contrast to the Christian doctrine of that era—does not orbit the Earth. He studied with Copernicus, an astronomer and physician, for two years as his sole student, encouraging him to complete his work and publish it. In 1551 Rheticus published the most significant of his own works, the Canon doctrinae triangulorum, which included many trigonometric tables.

  • Recasting the Heavens
    COMMENT BOOKS & ARTS icolaus Copernicus (1473–1543) was a quintessential unifier. He gathered the planets around a Ncentral Sun, thereby inventing the Solar System. The grand challenge facing biog- raphers of Copernicus is that few personal details survive. Was he gregarious? Did he have a girlfriend in his youth? When did he become interested in the stars? Because the historical record answers none of these questions, some authors have resorted to STOCK GEOGRAPHIC J.-L. HUENS/NATIONAL fiction. In A More Perfect Heaven, science historian Dava Sobel has it both ways. The first third of the book is strictly his- torical. It traces Copernicus’s life from his birth in Polish Toruń, to his undergraduate studies in Kraków and graduate work in Italy, and to his career as a legal, medical and administrative officer in the northernmost Catholic diocese of Poland. Sobel makes par- ticularly effective use of the records surviv- ing from when Canon Copernicus was the rent collector for the Frauenburg cathedral chapter’s vast land holdings. To fill the nar- rative, she occasionally quotes from John Banville’s novel “The grand Doctor Copernicus challenge facing (W. W. Norton, biographers 1976), but always of Copernicus makes clear that is that few those reconstruc- personal details tions are not taken survive.” from archival sources. What Sobel achieves is a brilliant chronological account — the best in the literature — laying out the stages of Copernicus’s administrative career. Having reached Copernicus’s final years, when publication of his still unfinished man- uscript seemed to have stalled, Sobel takes a new tack.

  • Copernicus' First Friends: Physical Copernicanism
    Filozofski vestnik Volume/Letnik XXV • Number/Številka 2 • 2004 • 143–166 COPERNICUS’ FIRST FRIENDS: PHYSICAL COPERNICANISM FROM 1543 TO 1610 Katherine A. Tredwell and Peter Barker Early assessments of the Copernican Revolution were hampered by the failure to understand the nature of astronomy in the sixteenth century, as scholars took statements made in praise of Copernicus to be implicit endorsements of his heliocentric cosmology. Gradually this view has been supplanted by the ac- knowledgement that many supposed partisans of Copernicus only endorsed the use of his astronomical models for the calculation of apparent planetary positions, while rejecting or remaining silent on the reality of heliocentrism. A classic example of this shift in historiography concerns Erasmus Reinhold (1511–1553), a professor of mathematics at the University of Wittenberg. Re- inhold’s use of Copernican models in his Prutenic Tables (Tabulae prutenicae, 1551) has led to the mistaken belief that he sanctioned a Sun-centered cos- mology as well. Careful reassessment of his published writings has revealed that he commended certain aspects of Copernicus’ work, such as the elimi- nation of the equant, but showed no interest in heliocentrism (Westman, 1975: pp. 174–178). Other supposed Copernicans, such as Robert Recorde (c. 1510–1558), expressed some openness to the Earth’s motion but left no clear indication of what they thought to be the true system of the world (Rus- sell, 1972: pp. 189–191). Between the publication of Copernicus’ epoch-making book On the Revo- lutions of the Celestial Orbs (De revolutionibus orbium coelestium) in 1543 and the year 1610, only a handful of individuals can be identified with certainty as Copernicans, in the sense that they considered heliocentrism to be physically real and not merely a calculational convenience.
