Paper Structure

There will be two 1.5-hour classes per week. Each class will include both lecture and discussion. The paper will begin with a close reading of some of Descartes's central works, emphasising the Meditations together with some important correspondence. Important doctrines include:

  • Cartesian structuralism
  • The place of sense experience in Cartesian epistemology
  • A priori knowledge and its place in Cartesian science
  • The Cartesian circle
  • The role of God in Cartesian epistemology and metaphysics
  • The mind/body relation
  • The transparency of the mental
  • Descartes's theory of error

We will then turn to Spinoza's Ethics. Spinoza uses Cartesian terminology and clearly takes up some Cartesian themes. We will examine the extent to which Spinoza is a Cartesian. Important doctrines include:

  • Monism
  • The theory of attributes
  • The substance/mode relation
  • Naturalism
  • Necessitarianism
  • Determinism
  • Spinoza's critique of traditional religion
  • The adequacy of ideas
  • The three kinds of knowledge
  • The critique of free will

The last third of the paper will be devoted to several works of Leibniz, a critic of both Descartes and Spinoza. Leibniz is sometimes presented as a great reconciler of pre-Cartesian scholastic philosophy and Cartesian views. We will test this thesis. Important doctrines include:

  • The principle of sufficient reason
  • The best of all possible worlds hypothesis
  • The concept containment theory of truth
  • Pre-established harmony
  • The theory of monads


  • Two essays 30% each
  • Exercises 10%
  • Examination 30%

Different exams will be offered to PHIL 231 and PHIL 331 students and different standards will apply to the assessment of papers.
