Epistemology, Metaphysics, and Logic Program


Choosing A Coherent Pathway

The Department of Philosophy offers a unified program of study in epistemology, metaphysics, and logic led by leading researchers in these fields.

Epistemology is the study of knowledge and rationality, focusing on questions such as how knowledge of things outside our immediate experience is possible and how we should change our beliefs in response to evidence. Metaphysics is the study of being, of what it is that makes up our world. Metaphysicians are interested in the nature of the mind, possibility, causation, time, and properties, among other things. Finally, logic is the study of truth, focusing on inference or deduction, from a formal perspective.

Students studying Epistemology, Metaphysics, and Logic will enter into some of the central debates in contemporary philosophy. The program’s units of study centre on specific philosophical problems, with each course building on skills and knowledge acquired in the student’s previous courses.

Regular events – conferences, workshops, seminars, and reading groups – bring together researchers from Sydney and around the world to engage with original, cutting-edge work.

Studying Epistemology, Metaphysics, and Logic

Many first-year units of study have elements that focus on epistemology, metaphysics, or logic. Following first-year units, students have access to a wide range of topic-centred advanced units, as well as intensive Honours seminars.

Collaboration with Other Departments and Centres

The problems focused on by epistemology, metaphysics, and logic are not confined to philosophy. For instance, the nature of rationality is of profound interest to economists, and the nature of the mind is also studied by cognitive scientists. The program in Epistemology, Metaphysics, and Logic collaborates with a number of other departments and encourages to consider opportunities for interdisciplinary research.

  • Economics
  • Cognitive Science
  • Mathematics
  • Computer Science
  • Sydney Centre for the Foundations of Science
