Philosophy and Ancient Greek Thinkers

What is Philosophy?

• Philosophy explores fundamental questions of existence, knowledge, and morality.
• It involves critical thinking, analysis, and systematic approaches to understand human experience and reality.

Ancient Greek Philosophers

• Ancient Greek philosophers laid the groundwork for Western philosophical thought, significantly exploring concepts of the self and existence.

Socrates (Know Thyself)

• Famous for the quote, "An unexamined life is not worth living."
• Proposed a dualistic view of humanity: body (imperfect, transient) and soul (perfect, eternal).
• Emphasized the importance of reason for self-discovery, virtue, and happiness.
• Asserted that a meaningful life arises from knowledge of oneself through constant soul-searching.

Plato (The Soul is Immortal)

• A student of Socrates, he built on his ideas with a notion of self-knowledge and soul purification.
• Advocated that the mind and soul are inherently perfect, created by God.
• Suggested genuine happiness is achieved when rational thinking governs one's spirit and desires.

Aristotle (The Soul is the Essence of the Self)

• A student of Plato, challenging the dualism concept; viewed body and soul as unified.
• Described the soul as the Form of the body, inseparable from it.
• Promoted the idea of various kinds of souls defining different living beings.

Other Philosophers

St. Augustine

• Merged Platonic ideas with Christian thought, emphasizing the soul's connection to the body.
• Believed humankind reflects God's image, inherently inclined toward goodness.
• Suggested self-knowledge arises from understanding one's relationship with God.

Rene Descartes

• Famous for the phrase "I think, therefore, I am," asserting self-awareness as proof of existence.
• Distinguished between two entities: the mind (thinking) and the body (extension in space).

John Locke

• Proposed "The self is consciousness," introducing the idea of the mind as a tabula rasa (blank slate) at birth.
• Argued that personal identity develops through sensory experiences over time.
• Emphasized consciousness as essential for maintaining a coherent self-identity.

David Hume

• Questioned the notion of a permanent self, claiming "There is no self."
• Described the self as a collection of rapidly changing perceptions, created by imagination.

Immanuel Kant

• Claimed "We construct the self," suggesting that selfhood is tied to knowledge acquisition.
• Believed that rationality allows the self to transcend sensory experience and create a coherent reality.

Gilbert Ryle

• Put forth the idea "The self is the way people behave."
• Argued that the self cannot be analyzed as a separate entity but is instead the aggregate of observable behaviors.
