Philosophy

Director of undergraduate studies: Daniel Greco, 106A C, 432-1687; philosophy.yale.edu

The Philosophy major prepares students to reflect critically and creatively on questions concerning the nature of things, the scope and limits of human understanding, and the principles of value and right action. The aim of the major is to address these questions wherever they arise, whether in the philosophical tradition, in other disciplines and practices, or in everyday life. Our courses are designed to encourage depth in thinking, rigor in argument, clarity in writing and speaking, and the widest possible view of whatever subject matter we take up.

Courses for Nonmajors and Majors

Introductory philosophy courses, numbered 100 through 199, are open to all students and have no prerequisites.

Course Numbering

Courses numbered 100 through 199 are introductory and have no prerequisites. Courses numbered 200 through 399 are intermediate. Some have prerequisites; others do not, and may be taken as a student's first course in philosophy, though such a student should consult the instructor first. In general, it is a good idea to take a broadly based course in any area of philosophy before taking a specialized course. Courses numbered 400 through 499 are seminars. These advanced courses are intended primarily for juniors and seniors, though other students may be admitted with the instructor's permission. Undergraduates should be sure they have enough background to take such a course, including previous work in the same area of philosophy. Students with questions should consult the instructor.

Prerequisites

Standard major Prerequisite to the standard major are two introductory or intermediate philosophy courses. 

Psychology track Prerequisite to the major in the psychology track are two courses in philosophy or psychology.

Requirements of the Major

The standard major The major requires twelve courses (including the prerequisites and the senior requirement) that collectively expose students to a wide range of philosophy and philosophers. The Philosophy curriculum is divided into three broad groups: history of philosophy; metaphysics and epistemology; and ethics and value theory. In history of philosophy, majors are required to take (a) either PHIL 125 and 126 or both terms of Directed Studies (DRST 003, 004), and (b) an additional, third course in history of philosophy. Majors are encouraged to take PHIL 125 and 126 as early as possible; these courses may be taken in either order. Majors must also complete two courses in metaphysics and epistemology, two courses in ethics and value theory, and a course in logic (such as PHIL 115), the last preferably by the fall of their junior year. Majors must also take two seminars (either or both of which can be counted toward one of the group requirements) and satisfy the senior requirement as described below.

All courses in Philosophy count toward the twelve-course requirement. With approval from the director of undergraduate studies (DUS), courses offered by other departments may be counted toward the major requirements, though no more than two such courses will normally be allowed.

Specific regulations for the group requirements are as follows:

  1. Some introductory courses do not count toward any group requirement. Other courses count toward a group requirement unless they are otherwise designated.
  2. Courses automatically count toward the group under which they are listed in this bulletin. In rare cases, a course will be designated as counting toward a second group, although no single course can be counted by the same student toward two group requirements. In addition, students may petition to have a course count toward a group other than the one under which it is listed in this bulletin, though the presumption will be against such petitions.
  3. Courses taken in other departments and applied to the major will not normally count toward a group requirement. Students may petition for credit toward a group requirement, though the presumption will be against such petitions.

The psychology track The psychology track is designed for students interested in both philosophy and psychology. Majors in the track must take seven courses in philosophy and five in psychology, for a total of twelve, including the prerequisites and senior requirement. The seven philosophy courses must include (a) two courses in the history of philosophy, usually PHIL 125 and 126 or DRST 003 and 004, (b) a course in logic, such as PHIL 115, preferably by the fall of the junior year, (c) two seminars, one of which may be in the Psychology department, with the approval of the DUS, and (d) at least two courses at the intermediate or advanced level that bear on the intersection of philosophy and psychology, at least one of which must be a philosophy seminar. Courses satisfying (d) must be approved by the DUS. The five psychology courses must include PSYC 110 or its equivalent. Each major must also satisfy the senior requirement as described below.

Credit/D/Fail No more than one course taken Credit/D/Fail may be counted toward the major, with the permission of the DUS. This applies to both the standard and the psychology tracks.

Senior Requirement

The senior requirement is normally satisfied by completing a third philosophy seminar. Students taking a seminar to satisfy the senior requirement are expected to produce work superior in argument and articulation to that of a standard seminar paper. To this end, students taking a seminar for the senior requirement must satisfy additional requirements, which may include (a) additional readings, (b) submission of a complete draft of the final paper by the eighth week of the term that will then be significantly revised, and (c) one-on-one or small-group meetings with the instructor to discuss class material, the additional readings, and drafts in preparation. The specific nature of these additional requirements will vary from seminar to seminar, so students planning to satisfy the requirement with a third seminar should express that intention to the instructor at the beginning of the term, so the instructor can explain the work that will be required. 

In special cases, students may meet the senior requirement through either a one-term or a two-term independent project supervised by an instructor (PHIL 490, 491). Students must petition to fulfill the senior requirement through an independent project, and approval is not guaranteed. Applicants must submit a proposal to the DUS, in consultation with an appropriate supervisor, by the end of the term prior to beginning the independent study.

Advising

Each major should, by October 1 of the junior year, secure the agreement of a member of the Philosophy department to serve as adviser for the year. The adviser aids the student in choosing courses and in planning for the senior year. All senior majors must have their schedules signed by the DUS.

Other majors involving philosophy Majors in Mathematics and Philosophy and in Physics and Philosophy are also available. Students interested in philosophy and psychology should also consider the major in Cognitive Science.

REQUIREMENTS OF THE MAJOR

Prerequisites Standard track—any 2 intro or intermediate phil courses; Psychology track—any 2 courses in phil or psych

Number of courses Both tracks—12 term courses, incl prereqs and senior req

Specific courses required Standard trackPHIL 125 and 126, or DRST 003 and 004; Psychology trackPSYC 110 or equivalent

Distribution of courses Standard track—3 courses in hist of phil (incl PHIL 125 and 126, or DRST 003 and 004), 2 in metaphysics and epistemology, 2 in ethics and value theory, and 1 in logic; 2 phil sems; Psychology track—7 courses in phil, as specified; 5 courses in psych

Substitution permitted Standard track—2 related courses in other depts, with DUS permission

Senior requirement Both tracks—a third sem in phil, or a one- or two-term independent project (PHIL 490, 491)

Philosophy attempts to find highly disciplined, rational ways of dealing with some of the deepest and most difficult issues in human thought and practice—for example, the nature of mind, the possibility or impossibility of knowledge, and fundamental principles of right and wrong. Philosophy thrives on disagreement; even within the Western tradition, no single approach is universally accepted.

Introductory philosophy courses, which are numbered from 100 to 199, are open to all students without prerequisites. Intermediate courses are numbered from 200 to 399; some have prerequisites, while others do not. Students should consult the instructor before taking an intermediate course as their first venture into philosophy. It is a good idea to take a general course in an area of philosophy before taking a specialized one.

One requirement for the major in Philosophy is a two-term introductory sequence in the history of philosophy. Either DRST 003 and DRST 004 (see Directed Studies) or PHIL 125 and PHIL 126 satisfies the requirement. The PHIL 125, PHIL 126 sequence need not be taken in the first year, though it is strongly recommended that the requirement be completed before the end of sophomore year.

The Department of Philosophy offers a wide range of introductory courses. Expected offerings for 2019–2020 include:

  • PHIL 115 , First-Order Logic
  • PHIL 125, Introduction to Ancient Philosophy

Introductory Courses

* PHIL 091a, Philosophy of GamesMark Maxwell

In this class, we critically discuss a variety of puzzles that arise when thinking about games. Just what are games, anyway? And, how can thinking in terms of games help us understand the world? The notion of 'game' is a topic of interest in its own right, but games can also serve as as a model and metaphor for other parts of the world, including life as a whole and the exploration of other philosophical debates. As such, the study of games serves as an entry point to a number of topics of potential interest, rather than just an in-depth study of one topic. Enrollment limited to first-year students. Preregistration required; see under First-Year Seminar Program.   HU

Seminars

* PHIL 493b / ANTH 428b / RLST 428b, Neighbors and OthersNancy Levene

This course is an interdisciplinary investigation of concepts and stories of family, community, borders, ethics, love, and antagonism. Otherwise put, it concerns the struggles of life with others – the logic, art, ethnography, and psychology of those struggles. The starting point is a complex of ideas at the center of religions, which are given to differentiating "us" from "them" while also identifying values such as the love of the neighbor that are to override all differences. But religion is only one avenue into the motif of the neighbor, a fraught term of both proximity and distance, a contested term and practice trailing in its wake lovers, enemies, kin, gods, and strangers. Who is my neighbor? What is this to ask, and what does the question ask of us? Course material includes philosophy, anthropology, psychology, fiction, poetry, and film.  HU

* PHIL 494a, Topics in KantThomas Pogge

Featuring some of the most important and difficult texts in philosophy, this seminar involves a close reading of Kant's works from one subset of his philosophy. It also guides students to identify and engage with the most insightful secondary literature and to grapple with Kant's arguments both orally and in writing. Each instantiation of the seminar selects readings according to student and instructor interests, with a focus for instance on Kant’s epistemology, centering around his Critique of Pure Reason, on his moral philosophy, as developed in his Groundwork and Critique of Practical Reason, or on his political philosophy and teachings about human progress. Students may take this seminar twice in consecutive years, provided a different set of Kant's works is covered. Prerequisites: Two courses in the history of philosophy, or one such course with the instructor's permission.  WR, HU

The course focuses on careful reading of the Gorgias with a view to engaging these philosophical topics. All readings are in translation, though a Greek reading group may be added for interested and suitably qualified students. Taught seminar-style, engaged, active student participation is expected. Class discussion typically starts from student questions circulated in advance.
