Overview

  • Introduction

Introduction

The Department of Philosophy, Logic and Scientific Method is a world-leading centre for research in three broad areas of philosophy: rational choice theory and formal epistemology; philosophy of science; and moral and political philosophy.

We accept MPhil/PhD students wishing to work in any field of research in which the department has special expertise, including philosophy of the natural sciences (especially physics and biology); distributive justice and normative ethics; philosophy and public policy; philosophy of the social sciences (especially economics); decision theory, evolutionary and game theory; and formal epistemology.

We're committed to research that makes a difference not only to philosophy and the philosophies of the various sciences, but also to the practice of the sciences themselves – from economics and political science to physics, biology and medicine – as well as to the wider world. The department’s teaching is research-led: courses cover cutting-edge material and are taught by some of the field’s leading scholars.

On this programme you'll work towards producing a substantial piece of work that makes an original contribution to the subject and is of a sufficient standard to give rise to publications in professional academic journals.

You'll benefit from the department’s close association with the Centre for Philosophy of Natural and Social Science , which hosts leading visiting scholars and supports a range of research projects, seminars and lecture series, and The Forum for Philosophy , which runs a full and varied programme of philosophy and interdisciplinary events. You'll also have the opportunity to attend and take part in the department’s regular seminar and lecture series, including the Choice Group on decision theory and social choice, and the Sigma Club on the philosophy and foundations of modern physics.

As a Philosophy MPhil/PhD student you'll be given the chance to teach the undergraduate discussion classes that are run in parallel with lectures. An essential part of becoming a good philosopher is learning how to teach, share and discuss ideas with those interested in philosophy at all levels, and the discussion classes you lead at LSE will provide ample opportunity.

Entry requirements

The minimum entry requirement for this programme is a taught master’s degree (or equivalent) in philosophy (or a sufficiently relevant discipline). We normally accept only those who achieve the equivalent of a distinction overall and in the dissertation component of their master's degree.

Competition for places at LSE is strong. So, even if you meet the minimum entry requirements, this doesn't guarantee you an offer of a place.

However, please don’t feel deterred from applying – we want to hear from all suitably qualified students. Think carefully about how you can put together the strongest possible application to help you stand out.

Programme content

In addition to making progress on your PhD project, you're expected to take the listed training and transferable skills courses. You may take courses in addition to those listed and should discuss this with your supervisor. All programmes of study should be agreed with your supervisor at the start of the year.

  • Year 1
  • Year 2
  • Year 3
  • Year 4

Year 1

The first “coursework” year prepares you for research in philosophy and the completion of a central thesis chapter. At the end of this first year your progress is reviewed to establish that you're on track to upgrade from MPhil to PhD status. In consultation with your academic supervisors, you also settle on a definite research topic by the end of the first year.

In addition to the courses below, you take optional (examined/not examined) transferable skills courses offered by the Teaching and Learning Centre or the Methodology Institute.

Students who have never taken a paper in formal logic at degree must take one of the following

  • Students who have never taken a paper in formal logic at degree must take one of the following:: PH503 Half unit Logic and Probability I PH504 Half unit Logic and Probability II

  • EITHER Three term units of PhD level seminars with associated coursework OR one further master's-level course not already taken and the following:: Courses to the value of one unit of PhD Seminars

Year 2

From Year 2 PhD students dive deep into the research and writing of their thesis. While writing your thesis you attend the department’s Popper Seminar, but also any of the wealth of regular research seminars that may be relevant to your research. You take optional (examined/not examined) transferable skills courses offered by the Teaching and Learning Centre or the Methodology Institute.

Students in their second year aim to write two or three further chapters beyond the chapter they completed in their first year.

Year 3

In the third year you produce a draft of the entire thesis, while writing papers, submitting to conferences, and getting to know the dynamic field of philosophy and their place in it. You attend the department's seminars (listed below) and take optional (examined/not examined) transferable skills courses offered by the Teaching and Learning Centre or the Methodology Institute.

Year 4

In the fourth year, you polish your material and prepare to go on the job market. You also attend the department's seminars (listed below) and take optional (examined/not examined) transferable skills courses offered by the Teaching and Learning Centre or the Methodology Institute.

A few important points you’ll need to know:

We may need to change, suspend or withdraw a course or programme of study, or change the fees due to unforeseen circumstances. We’ll always notify you as early as possible and recommend alternatives where we can.

The School isn't liable for changes to published information or for changing, suspending or withdrawing a course or programme of study, due to developments in teaching practice, regulatory requirements that require us to comply, lack of demand, financial unviability of a course, or due to circumstances beyond our control, such as the loss of a key member of staff or where a location or building becomes unavailable for use.

Places are limited on some courses and/or subject to specific entry requirements so we cannot therefore guarantee you a place.

Changes to programmes and courses may be made after you’ve accepted your offer of a place – normally due to developments in the discipline or as a consequence of student feedback. We may also make changes to course content, teaching formats or assessment methods but these are made to improve the learning experience.

For full details about the availability or content of courses and programmes, please take a look at the School’s Calendar , or contact the relevant academic department.

Some major changes to programmes/courses are posted on our updated graduate course and programme information page .

Your application

  • Overview
  • When to apply

Overview

We welcome applications for research programmes that complement the academic interests of our staff at LSE. For this reason, we recommend that you take a look at our staff research interests before applying.

We carefully consider each application and take into account all the information included on your form, such as your:

See further information on supporting documents .

You may need to provide evidence of your English language proficiency. See our English language requirements .

Research proposal

This is an important document, which should provide a description of your likely research topic for your PhD. (There is scope for changes in this topic during the first year. In consultation with your academic supervisor, you'll need to settle on a definite research topic by the end of that year.) So long as you provide a brief summary of your entire research project at the outset, it's not a problem to exceed the suggested 1,500 word limit even by a significant amount. If you already have a well-worked-out PhD project, you are in fact encouraged to supply a detailed description, which may include chapter by chapter summaries. If you'd like your project to be supervised by a particular member or members of the department, please indicate this in your proposal. Contrary to LSE's general guidance on research proposals, you don't need to provide either a description of the methodology you'll employ or case studies, as these particular guidelines are for dissertations in the social sciences rather than philosophy.

Please note that a precise research topic can be accepted only if someone in the department is well-placed to supervise such a project.

Writing sample

This is another important document. It's not a problem to include a writing sample that exceeds 3,000 words even by a significant amount, so long as you indicate, at the outset, a 3,000 word subset of this longer piece of writing on which the selection committee should focus their attention. It's not necessary to provide a scanned copy of your writing sample. You may, for example, simply upload a Word file.

Please note that LSE allows part-time PhD study only under limited circumstances . If you wish to study part-time, you should mention this (and the reasons for it) in your statement of academic purpose, and discuss it at interview if you're shortlisted.

  • academic achievement (including existing and pending qualifications)
  • statement of academic purpose
  • references
  • CV
  • outline research proposal
  • sample of written work.

Learning and assessment

  • How you learn
  • How you're assessed

Supervision

PhD students in the department work with two supervisors from the academic faculty to ensure a wide range of advice. The choice of secondary supervisor can be quite flexible (and occasionally includes academics from outside the department). The primary supervisor is a senior member of staff. Both primary and secondary supervisory arrangements can change in the course of the degree as your thesis develops.

How you're assessed

Progression and assessment

Successful completion of work required for each year is a necessary condition for re-registration in the following year; and for upgrading from MPhil to PhD status. During the first year you must write a first chapter of the thesis as well as an outline (research plan) of the rest of the thesis. The chapter should be around 40 pages; the research plan around 10 pages. This upgrading will normally take place after the successful completion of Year One requirements in Case A, and after the successful completion of Year Two requirements in Case B. In both cases, once you're registered for the PhD that registration will be backdated to the start of your MPhil/PhD studies.
