British Empiricism: Locke, Berkeley, and Hume

The empiricist tradition that grounded all knowledge in sense experience, tracing a line from Locke's theory of ideas through Berkeley's idealism to Hume's radical skepticism about causation and the self.

60-Second Review

Express review

A condensed, point-by-point summary of the module, for reviewing right before a test or exam.

  1. Locke's Essay Concerning Human Understanding and the Tabula Rasa. Locke's 1689 Essay argues the mind starts as a blank slate filled only by experience.
  2. Locke on Primary and Secondary Qualities. Locke distinguishes qualities inherent in bodies from those that exist only as perceived effects.
  3. Berkeley's Idealism: Esse Est Percipi. Berkeley argues that to exist, for anything material, is simply to be perceived.
  4. Berkeley's Critique of Abstract Ideas and Material Substance. Berkeley denies both general abstract ideas and an unperceivable material substratum.
  5. Hume's Theory of Impressions and Ideas. Hume divides all mental contents into vivid impressions and their fainter copies, ideas.
  6. Hume on Causation, Induction, and Custom. Hume argues causal necessity is habit, not perceived connection, undermining inductive certainty.
  7. Hume's Skepticism about the Self and Personal Identity. Hume finds no impression of a constant self, only a bundle of fleeting perceptions.
  8. Hume's Moral Philosophy and the Is-Ought Problem. Hume grounds morality in sentiment, not reason, and flags the leap from is to ought.

This module continues after "Cartesian Rationalism and Continental Metaphysics" in the syllabus. If you haven't reviewed it yet, it may help set the context.
