DPhil in Philosophy

The Doctor of Philosophy (DPhil) in Philosophy is a three- to four-year research programme in which a candidate undertakes a doctoral level research project under the guidance of a supervisor. The doctoral work culminates in a 75,000-word thesis that is defended in the form of a viva voce examination (oral defence). Satisfactory progress through the DPhil is checked in the form of a mini-viva voce examination taking place at the end of the first and second year of study.

The aim of the Faculty’s DPhil in Philosophy is to prepare you for an academic career in philosophy.

For information on how to make an application please see our Admissions Procedure and Entry Requirements page.

The Philosophy Graduate Studies Committee recommends progression from Oxford's BPhil in Philosophy to the DPhil programme in view of the opportunity it offers to students to study a wide range of philosophical topics as well as to focus on a narrower field of research interest. Students proceeding to the DPhil programme via the BPhil will normally write a DPhil thesis which is an expansion of their BPhil thesis, although this is not a formal requirement. Indeed, sometimes, the BPhil thesis topic is not suitable for expansion into a DPhil thesis, or a student may wish to write their DPhil thesis on a different topic.

Each year, some students are admitted to the DPhil in Philosophy from programmes other than the BPhil in Philosophy. These students enter the DPhil initially as Probationary Research Students (“PRS”) from appropriate programmes at Oxford or elsewhere. Typically, these students will have already completed substantial graduate work in philosophy, usually equivalent to that required for the BPhil. Students may also progress from a specialist MSt programme, for example from the MSt in Philosophy of Physics or the MSt in Ancient Philosophy.

In the third term after enrolment onto the DPhil, you are required to complete a transfer of status from PRS to full DPhil status. Two appointed examiners will interview you both on your two-page thesis outline, which explains in outline the intended line of argument or contribution to the subject, and on a piece of written work of approximately 5,000 words in the area and philosophical style of the proposed thesis which is typically, though not necessarily, a draft chapter of the thesis. Students will also normally be expected to submit an additional essay of up to 5,000 words as part of their application to Transfer status, on a philosophical subject that differs from their doctoral research.

Students who progressed from the MSt in Philosophy of Physics course are required to write a 20,000-word thesis during their year as a PRS, as their MSt does not have a thesis element. Students who progress from the BPhil will enter the DPhil without being required to pass a year as a PRS.

At the end of the second year (or first year, if you have progressed from the BPhil), you will be required to apply for confirmation of DPhil status. This entails an interview by one or two appointed examiners on your two-page thesis outline, which goes into some detail and comprises a reasoned statement of the nature of the proposed thesis together with a provisional table of contents, and a piece of written work of approximately 5,000 words.

You should have regular one-on-one tuition sessions with your supervisor(s). These will normally happen twice per term but in some terms, especially at the start of the degree and during the final stages of the thesis, the number of sessions may be increased. You are not required to attend any taught graduate classes as part of your DPhil degree, but you are encouraged to participate in lectures, classes, seminars and other educational opportunities offered throughout the university as relevant to your topic of study.

The course has no fieldwork, industrial placement or year abroad element, but you may decide to attend conferences, workshops or research training elsewhere.
