📖 1. Self-Consciousness and Self-Knowledge

🔑 Key Concepts & Definitions

• Self-consciousness: The reflective capacity by which a subject takes itself as the object of its own thought.

📝 Essential Points

📌 Self-consciousness differs from immediate awareness of external things, such as seeing or listening, and from moral consciousness, which concerns knowledge of good and evil.

• The course presents the etymology of consciousness as meaning “being informed” and connects the Latin scientia with knowledge.

💡 Memory Hook

Immediate awareness faces outward; reflective self-consciousness takes the self as its object.

📖 2. Descartes and the Cogito

★ Must-know

• Even if everything is doubted, the act of doubting establishes that the doubter thinks and exists: “I think, therefore I am” (Cogito ergo sum). - Descartes, Méditations métaphysiques

• Descartes’s doubt has three characteristics:

  • radical
  • methodical
  • hyperbolic

Further detail

• Descartes doubts sensory truths using the possibility that the senses sometimes deceive and the argument that dreams can be indistinguishable from waking reality. - Méditations métaphysiques

• Descartes challenges truths of reason, including logic and mathematics, with the hypothesis of a possible deceiving evil genius. - Méditations métaphysiques

• For Descartes, consciousness is a metaphysical reality capable of thinking itself. - Méditations métaphysiques

💡 Memory Hook

Doubt the senses, doubt reason, then find the thinking self that doubt cannot erase.

📖 3. Consciousness and Human Finitude

🔑 Key Concepts & Definitions

• Diversion: For Pascal, diversion consists of activities such as politics, work, alcohol, gambling, and lust that keep people from thinking about death and give them an illusion of happiness.

📝 Essential Points

• The course presents consciousness of one’s condition in the universe as including awareness of human finitude and mortality. - David Hume

• Pascal presents consciousness as paradoxically revealing both human greatness and human weakness.

💡 Memory Hook

Awareness of mortality brings tragic lucidity; diversion distracts from it.

📖 4. Hume and Kant on Personal Identity

★ Must-know

• Hume argues that the self is a metaphysical fiction without empirical foundation and that introspection finds perceptions and impressions, which are weakened images of perceptions. - chapitre de la nature humaine

• Kant treats consciousness as a power, not a thing, that unites what a person experiences and makes it possible to think of oneself as one person.

Further detail

• Kant’s account is presented as a synthesis of idealism or rationalism associated with Descartes and empiricism associated with Hume.

💡 Memory Hook

Hume finds perceptions, while Kant treats consciousness as the power that unifies experience.

📖 5. Perception and the Unconscious

🔑 Key Concepts & Definitions

• Small perceptions: Leibniz’s theory of small perceptions holds that the mind receives perceptions but becomes aware, through apperception, of only part of its thoughts and their contents.

★ Must-know

📌 The course raises whether the difference between consciousness and the unconscious is merely a variable difference of degree based on perception or a difference in nature that makes some thought inaccessible to consciousness in principle.

• Freud uses such phenomena to develop the hypothesis that consciousness cannot explain everything.

Further detail

• Dreams, slips of the tongue, and failed acts are presented as phenomena that suggest that something in us acts without our awareness.

💡 Memory Hook

Small perceptions exceed awareness; dreams, slips, and failed acts point toward what acts outside it.

📖 6. Consciousness and New Realities

★ Must-know

• The course proposes that consciousness opens people to new realities rather than confining them to narrow self-knowledge incompatible with a free subject situated in history and politics.

Further detail

• The course asks whether self-knowledge is truly the purpose of consciousness and whether consciousness is directed only toward the self, as presented through Husserl.
