BSc Philosophy, Logic and Scientific Method

This BSc Philosophy, Logic and Scientific Method gives you the chance to examine deep philosophical questions alongside top researchers in the field.

You’ll engage in wide-ranging philosophical debates encompassing ethics, science and justice, such as:

• What is the nature of reality?
• Is time travel possible?
• What is the justification for punishment?
• Can beliefs be morally wrong?
• What is the role of values in science?

During your studies, you’ll sharpen your skills in logical reasoning and argumentation, essay writing and speaking, and learn how to engage critically with difficult ideas. We encourage you to think outside the box and approach philosophical debates from different angles.

You’ll draw on our interdisciplinary knowledge across the social sciences and specialist expertise in the philosophy of science, moral and political philosophy and logic, decision theory and social choice.

Founded by Professor Sir Karl Popper in 1946, our department is internationally respected for its teaching and research in philosophy. LSE was ranked second in the UK and eighth in the world for philosophy in the QS World University Rankings by Subject 2026. Our graduates progress to many rewarding careers in finance, accounting, management consulting, IT and tech, as well as postgraduate research.

Formative coursework

All taught courses include formative coursework, which is not assessed. This helps prepare you for summative assessment. We use a wide range of formative assessment methods, such as essays, case studies, reports, quizzes and mock exams.

Feedback on coursework is an essential part of the learning experience. Class teachers mark formative coursework and feedback is normally given within two weeks – provided the work is submitted on time.

Summative assessment

This counts towards your final course mark and degree award.

Summative assessment varies depending on the course. Typically, you’ll have an essay for each course (due at the beginning of May) and an exam in June.

For each course, you’ll complete several essays and/or exercises as part of your class work.

Assessment on individual courses can change from year to year. You’ll receive feedback on summative coursework as part of the assessment for individual courses (except on final submitted dissertations). Feedback is normally provided before the examination period.

Learn more about the current formative coursework and summative assessment for each course in the relevant course guide.
