- Der Sinn des Lebens (falls es so was gibt) (Rapp)
 Es besteht die verbreitete Erwartung, dass sich Philosophie traditionell mit Fragen befasse, die mehr oder weniger direkt mit „dem Sinn des Lebens“ zu tun haben. Viele professionelle Philosophinnen und Philosophen vor allem der analytischen Tradition geben sich aber eher skeptisch oder zugeknöpft, wenn es zu Fragen nach dem Sinn des Lebens kommt, unter anderem weil viele den Verdacht hegen, die Frage nach „dem Sinn des Lebens“ sei selbst sinnlos oder könne nicht mit den Methoden der analytischen Philosophie beantwortet werden. Erst in jüngerer Zeit gibt es ausgehend von den Arbeiten der Moralphilosophin Susan Wolf eine vertiefte Forschungsdebatte über den Sinn des Lebens bzw. über „Sinn im Leben“. Die Vorlesung soll die Problematik der Frage nach dem Sinn des Lebens aufzeigen und in die genannte neuere Forschungsdebatte (die am ehesten in der Ethik/Moralphilosophie, Metaethik angesiedelt ist) einführen. Behandelt werden daher vorzüglich Autorinnen und Autoren des 20. und 21. Jahrhunderts (u.a. A.J. Ayer, Kurt Baier, David Wiggins, Thomas Nagel, Robert Nozick, Susan Wolf, Thaddeus Metz, John Cottingham, Iddo Landau), aber auch Beispiele aus der Philosophiegeschichte (S. Kierkegaard, F. Nietzsche), der Literatur (u.a. Leo Tolstoi, Albert Camus) und dem Film (u.a. Monty Python, The Truman Show) werden herangezogen.
 Folgende Themen werden behandelt: Ist die Frage nach „dem Sinn des Lebens“ sinnlos? – Sinn des Lebens und Sinn im Leben – Sinn und Religion/Transzendenz (Supernaturalistische Theorien des Sinns) – Sinn des Lebens und die kosmische Perspektive – Sinnleere/das Absurde/Anti-Sinn – Sinn und das gute Leben – Sinn und Moral – Objektivistische und subjektivistische Theorien des Sinns – Sinnhafte Projekte als Beitrag zum guten Leben – Sinn und Tod/Sterblichkeit.

- Socrates and the Socratic Schools (Chame)
 This seminar focuses on the phenomenon of the Socratic dialogue (sokratikós lógos) as a key to understanding Socrates and the first generation of Socratics. We will begin by addressing the so-called “Socratic question” and then study Socrates through the works of Plato, Xenophon, and the extant testimonies of other Socratics such as Antisthenes of Athens, Aristippus of Cyrene, Aeschines of Sphettus, and Euclid of Megara. All these philosophers present different portrayals of Socrates, so one of our main tasks will be to analyze the points of commonality and the differences between them. Finally, we will overview the later development of the Socratic schools throughout the fourth and early third centuries BC.
 Mon. 10-12, Musaph Seminar Room (Leopoldstr. 11b, Room 433)
- Aristotle’s Rhetoric (Rapp)
 Aristotle’s Rhetoric can be considered the first comprehensive introduction into argumentation theory. At the same time, the Rhetoric is crucially embedded into other parts of Aristotle’s oeuvre, in particular, it is connected with his Topics and his works on moral philosophy and psychology. Aristotle thinks of rhetoric as being a counterpart to dialectic, the method by which philosophers are able to provide arguments on any subject. Indeed, Aristotle regards arguments or proofs as central to persuasion. However, people are not always willing to accept the conclusion of a compulsive argument, for example they might be reluctant to accept a suggested conclusion if they happen to be in an averse emotional state. This is why an essential section of the Rhetoric includes the by then most comprehensive discussion of several types of emotions.
 Tues. 16-18, Musaph Seminar Room (Leopoldstr. 11b, 433)
- Reading Aristotle in Greek (Isépy)
 Einführung in die Autorenlektüre/Reading Greek Philosophy in Greek (Isépy): Aristoteles, De partibus animalium I
 Tues. 18-20, Musaph Seminar Room (Leopoldstr. 11b, 433)
- Introductions to Platonism in Late Antiquity: Alcinous’s Didaskalikos and Porphyry’s Sentences (Adamson)
 This seminar will be devoted to two late ancient texts that present the thoughts of great Platonists in condensed and expository form. First, the Handbook or Didaskalikos of Alcinous, a Middle Platonist primer on the dialogues of Plato; and second, the Sentences of Porphyry, which serves something like the same function for Plotinus. While these works may seem derivative and hence uninteresting, they in fact take care to structure and unify the thought of the authoritative author in question, ironing out inconsistencies and turning corpora that are often rather ambiguous and elusive into bodies of doctrine. Both works will be read in English but with reference to the Greek; for the seminar we will be joined (online) by Prof Tad Brennan of Cornell University.
 Weds. 16-18, Musaph Seminar Room (Leopoldstr. 11b, 433).
- Al-Ghazali, Revival of the Religious Sciences (Arabic reading seminar) (Adamson, Hansberger)
 Al-Ghazali is most famous among philosophers for his refutation of Ibn Sina in the Incoherence of the Philosophers; his intellectual autobiography, Deliverer from Error, is also a well-known text. But these represent only a fraction of his multifaceted and prodigious output. His significance as an Islamic theologian is perhaps most secured through his enormous Revival of the Religious Sciences (Ihya’ ‘Ulum al-Din), which explores many features of Islamic practice and spirituality. Many sections are informed by al-Ghazali’s profound engagement with philosophy, and in this seminar we will read selections from Book 21, “The Marvels of the Heart” where, among other things, al-Ghazali discusses the difference between rational and inspired knowledge.
 Tues. 10-12, Musaph Seminar Room (Leopoldstr. 11b, 433)

- Scientific status of Metaphysics in Aristotelian Tradition (Hansberger, Genç)
 In this seminar we will survey accounts on the scientific status of metaphysics in Greek and Arabic Aristotelianism. What Aristotle says about what sort of science metaphysics is in his Metaphysics raises some questions about the subject-matter and the structure of metaphysics as a science. First of all, what is the subject-matter of metaphysics? In this science, do we study the most general features shared by all that exists, i.e., “being qua being and its per se attributes,” or the ultimate causes of everything, which are “separate and immovable” beings? If it is both the general features and the ultimate causes of all that is, how should we understand the relation between the study of each so that the term “metaphysics” would turn out to pick out one genuine science rather than being an equivocal umbrella term for two different sciences with different subject-matters? Does metaphysics also study some common principles like the principle of non-contradiction? If so, again, do we have a genuinely single science that studies the other things mentioned before and also the common principles like the principle of non-contradiction? This brings us to the question of how we should individuate sciences according to Aristotle. What characterizes a science? When we have a body of knowledge, how can we know whether this body of knowledge constitutes exactly one complete science? Finally, is metaphysics a demonstrative science? If it is not a demonstrative science, what sort of method secures the reliability of metaphysical knowledge? If it is a demonstrative science, is it just like any other demonstrative science or does metaphysics differ from the others in some important respects? To address these questions meaningfully, we should also have at least an outline view of what a demonstrative science is for Aristotle and how it is organized.
 The seminar has three main units. The first unit is on Aristotle, where we will read passages from Aristotle’s Metaphysics and Posterior Analytics. The second unit is on late antique Greek commentaries on Aristotle; here we will focus mainly on selections from Alexander of Aphrodisias’ commentary on the Metaphysics, but will also look at the division of philosophy accounts we find at the beginning of the Alexandrian Greek commentaries on Porphyry’s Isagoge. The third unit is on medieval Arabic philosophy. Here we will look at discussions of the subject-matter of metaphysics and the order of sciences by al-Kindi (On First Philosophy), al-Farabi (On the Aims of Metaphysics; Enumeration of the Sciences and other texts), and Ibn Sina (Healing).
 The seminar will be conducted in English; the primary texts will be made available in English translation. Knowledge of Greek and/or Arabic is not required.

- Stoic metaphysics (Chiocchetti)
 The Stoic metaphysical system is one of the great intellectual achievements of the Hellenistic period, yet it survives only in fragments and later testimonies. This research seminar is dedicated to the challenging but rewarding task of reconstructing and critically assessing this influential philosophy. We will focus on Chrysippus’ mature system.
 Our work will be twofold: first, a careful, methodologically aware reading of the primary evidence; second, a critical engagement with the major lines of interpretation in contemporary scholarship. We will deal with the core debates surrounding Stoic thought: the coherence of their corporealism, the function of the two ‘first principles,’ the intricate theory of causes, the controversial status of the four ‘incorporeals’ (lekta, place, void, and time), and the Stoic solution to the problem of universals. Our primary text will be Long and Sedley's The Hellenistic Philosophers (available online via the university library).
 Weds. 10-12, Musaph Seminar Room (Leopoldstr. 11b, 433)
- Plato's Hippias Major and Hippias Minor (Spinka)
 Hippias Major and Hippias Minor, while not among Plato’s most renowned dialogues, offer an intriguing read due to their dramatic connection and broad topical range. They present another confrontation between Socrates and a sophist, which is always entertaining to observe. Moreover, they delve into a profound philosophical concept: the noble (το καλόν). What makes something beautiful and admirable? Our discussion will continue with Hippias Minor, exploring ethical themes. Notably, this dialogue presents a shocking claim that virtuous and knowledgeable individuals can engage in shameful acts, contradicting the notion of nobility and admiration. We will explore these topics and address the scholarly debate on whether both dialogues are truly Socratic.
