METAPHYSICS-What is the nature of REALITY?

EPISTEMOLOGY-What is the nature of KNOWLEDGE?

AXIOLOGY- What is the nature of VALUES?

METAPHYSICS

ONE OF THE KEY CONCEPTS OF UNDERSTANDING PHILOSOPHIESCONCERNED WITH REALITY AND EXISTENCE

ASKS: WHAT IS THE NATURE OF REALITY?SUBDIVIDE INTO TWO CATEGORIES1.ONTOLOGY: What is the nature of existence2.COSMOLOGY: Origin and organization of the universe

EPISTEMOLOGY

RAISES QUESTIONS ABOUT THE NATURE OF KNOWLEDGELOGIC IS A KEY DIMENSION TO EPISTEMOLOGY

TWO KINDS OF LOGIC:1.Deductive logic: from general to specific2.Inductive logic: from specific facts to generalization

AXIOLOGY

EXPLORES THE NATURE OF VALUES

ETHICS: study of human conduct and examines moral values

AESTHETICS: values beauty, nature, and aesthetic experience (often associated with music, art, literature, dance, theater, and other fine arts)

MAJOR TRADITIONAL PHILOSOPHY:

IDEALISMCONSIDERED OLDEST PHILOSOPHY OF WESTERN CULTURETHE WORLD OF MIND, IDEAS AND REASON IS PRIMARY

METAPHYSICS: stresses mind over matter (nothing is real except for an idea in the mind)

EPISTEMOLOGY: all knowledge includes a mental grasp of ideas and concepts

AXIOLOGY: values are rooted in realityIDEALISTS BELIEVE THAT VALUES CAN BE CLASSIFIED AND ORDERED INTO

A HIERARCHY

LEADING PROPONENTS OF IDEALISM

• PLATO- Greek Philosopher- considered father of idealism- ”Allegory of the Cave” from The Republic• AUGUSTINE- Theologian of 4th & 5th centuries- Applied Plato’s assumptions to Christian thought• DESCARTES, KANT & HEGEL- Descarte: “I think, therefore I am”- Kant: certain universal moral laws- categorical imperatives- Hegel: approached reality as “contest of opposites”

MAJOR TRADITIONAL PHILOSOPHY:

REALISMThe antithesis of IdealismUniverse exists whether mind perceives it or not

METAPHYSICS- reality composed of matter (body) and form (mind) EPISTEMOLOGY- sense realism (knowledge comes through senses) AXIOLOGY- values derived from nature

LEADING PROPONENTS OF REALISM

• ARISTOTLE- father of realism-student of Plato-argued that knowledge can be acquired through senses• FRANCIS BACON

-advanced a rigorous form of inductive reason• JOHN LOCKE

-theory of tabula rasa (no such thing as innate ideas)• COMENIUS, ROUSSEAU, and PESTALOZZI

MAJOR TRADITIONAL PHILOSOPHY:NEO-THOMISM

• Dates to the time of Thomas Aquinas (1225-1274)• Also known as theistic realism“God exists and can be known through faith and reason”

Metaphysics- God gives meaning to universe Epistemology- hierarchy of knowing God Axiology- unchanging moral laws

CONTEMPORARY PHILOSOPHIES:PRAGMATISM

Also known as experimentalism- experience or things that workPhilosophy of 20th century developed by John Dewey

Metaphysics- regard reality as an event or process. Meaning is derived from experience in environment.

Epistemology- truth is not absolute but determined by consequences. Arrived at by inquiry, testing, questioning, retesting, ect.

Axiology- primarily focused on values. Determined by own experiences

LEADING PROPONENTS OF PRAGMATISM

• AUGUSTE COMTE-suggested science could solve social problems-problem solving was key

CHARLES DARWIN-theory of natural selection implied reality was open ended, not fixed

AMERICANS: Charles Pierce, William James and John Dewey

CONTEMPORARY PHILOSOPHIES:EXISTENTIALISM

Appeared as a revolt against the mathematical, scientific philosophies that preceded it.

Focus on personal and subjective existence

Metaphysics- no purpose or meaning to universe. No world order or natural scheme of things

Epistemology- we come to know truth by choice. The authority is found in self.

Axiology- choice to determine value.

LEADING PROPONENTS OF EXISTENTIALISM

• SOREN KIERKEGAARD-Danish philosopher/theologian-Father of Existentialism-Rejected scientific objectivity for subjectivity and choice• MARTIN BUBER

-Jewish philosopher/theologian-”I/Thou” relationship- divine and human are related• HUSSERL and HEIDEGGER• JEAN-PAUL SARTRE

-We construct our own existence

ANALYTIC PHILOSOPHY

empirical types of scientific expression Shifted to Analytic philosophy in 1950’s Analytic philosophy has recently focused on political philosophy,

ethics and philosophy of human sciences
