Critique of Pure Reason: A Summary
Critique of Pure Reason
Introduction
Knowledge originates from two sources: sensibility and understanding. Sensibility provides intuitions, while understanding designs concepts. Intuitions without concepts are blind, and concepts without intuitions are empty. Knowledge arises from the collaboration of both. The subject receives intuitions from external experience and spontaneously creates a priori concepts or categories to give meaning and unity to the intuition.

Hume: Empiricist Philosopher

Epistemology
Epistemology is the study of the extent of our knowledge before attempting to understand things. All science and knowledge are derived from human nature. For Hume, knowledge boils down

How Mill Defends the Usefulness of Action as the Foundation of Morality
Utilitarianism sets the greatest happiness principle as the moral foundation, stating that actions are right insofar as they tend to promote happiness. By happiness is intended pleasure and the absence of pain; by unhappiness, pain and the privation of pleasure.

Kant: Formal Ethics
Kant’s ethics differ from earlier material ethics, which focused on achieving the highest good (happiness, pleasure) through specific rules. Material ethics have three flaws:
- They are empirical (a posteriori), relying on experience, which cannot yield universal principles.
- They are hypothetical imperatives, dependent on the desire for a supreme good (e.g., “If you want X, do Y”).
- They are heteronomous, with reason receiving external instructions, thus lacking freedom.
