Epistemology
- study on knowledge; ideals with the nature of human world/consciousness -> gain knowledge about the truth
- 3 Questions
- What is knowledge/wisdom/certainty? [facts, reality, opinions, and knowledge]
- What is the nature of knowledge? [criteria, defining points of knowledge]
- How can one know reality? [how a human mind logically gain/understand reality]
- 3 Philosophical Systems of Epistemology: rationalism, empiricism, critical philosophy
Rationalism
- human intelligence is universal in all human minds
- Regardless of differences
- Optimistic
- Human reason is a defining element of a human person
- Human reason is the only means to certainty in knowledge
- Human reason is not unruly
- Logical way of thinking
- Reason is the only way to determine what is morally right and good and what constitutes a good society
- Reason is the gateway to reality
- Makes us distinguish good from bad — can promote just and orderly society
Rene Descartes
- supports reason as the only viable reason for the truth about life
- Paris, France (1596-1650)
- Elite society Father of Modern Philosophy
Modern Philosophy
- based on the spectrum of science
- Empowers the existence of men; prove God through human reason
- Europe (17th-19th century) -> origin [France and Germany]
- Epistemology and Metaphysics -> center
- Direct reason to the “Medieval Period” (theocentric)
- Medieval Period: man is finite-> cannot gain access to the truth; everyone glorified God as absolute truth; God-centered
- Descartes wants to restore faith in humanity (make humans progress)
- Rise of science -> step by step discipline
- Galileo exterminated from Christian society: “Can the physical world be understood mathematically without reference to God?”
Rene Descartes (cont’d)
- studied at “La Fleche” University (Jesuit order)
- One of the founders of Analytic Geometry
- Mathematics (i.e. Geometry)
- Intuition and Deduction
- Clear and Distinct
Theology is wrong
- based on faith which is blind
- Glorifies fiction instead of facts
- Serves as blockage/limitation to human reasoning
- Prevents men about learning new things in life
Intuition
- ability of the mind/human reason to arrive at something that is really true/certain
- Mind cannot help but accept it as true
Deduction
- the capacity of the mind that complements intuition
- To arrange certain truths in a logical sequence/hierarchy/ chronological
- Comprehensive wisdom about life
- 1–2–3
- Mathematics is ^^clear and distinct^^->test for the truth
DESCARTES’ EPISTEMOLOGY: The Meditation
- Main Objective: Total demolition and Reconstruction of human knowledge
FOUNDATIONAL PRINCIPLE: starting point/basis for certainty
- clear and distinct -> free of error
- Independent
- Autonomous; not dependent on anything; free from other truths to be certain
- The principle is a certain thing whose existence does not (…)
- Existence
- About something which is real/reality
Epistemology
- rework knowledge of the past [inadequate]
- Restructure based on own foundations and principles
- System-builders
- Mind-based
Best Philosophy - rigidly structured/uniformed at arriving at the truth
- Philosophy-Mathematics -> complementary at arriving at the truth
METHOD OF DOUBT: SKEPTICISM
- Doubt
- unsure about life
- Uncertainty
- Descartes reworked concept of skepticism
- Sophists - early skeptics
Descartes [“Skepticism”]
- attitude that questions the reliability of the knowledge
Methodological Skepticism
- methodical
- Doubt as prerequisite at arriving at the truth
- Doubting is the beginning of wisdom
- Senses/Sense Perception - deceiving; can be misleading “Plato’s Allegory of the Cave”; Father->God — chauvinistic society
- Material Bodies -> physical things; based on sense perception
- Natural Sciences - scientific disciplines study of nature/world; Chemistry, Physics; based upon sense perception
- related/unified with each other
Objective - Descartes wants to doubt personal sentiments
- Tries to falsify Mathematics [true and certain for Descartes]
- truths of human reasons -> should be falsified
- Should not be based on finite minds
- Hypothetical malevolent Demon Argument -> constantly deceiving us
- Falsify existence of God [all powerful and can deceive us]
- Substitutes God as Demon (nullify truths) ^^HYPOTHETICAL^^ = uncertainty
“Even if I am deceived in all my beliefs, I must exist in order to be deceived.”
I think, therefore, I am/Cogito ergo sum
- act of doubting/thinking confirms self to be real
DESCARTES’ MAIN OBJECTIVE IN HIS EPISTEMOLOGY (THE MEDITATIONS)
“Total Demolition and Reconstruction of Human Knowledge”
- Traditional knowledge is inadequate. It should be falsified.
- destroy knowledge inadequate of the past
- Once falsified, knowledge must be reconstructed according to principles known by “Reason”.
- recreate knowledge based on REASON-> best way to arrive at certain knowledge in life
- Descartes was a “system builder of knowledge”
*abandon old knowledge and reconstruct based on a better foundations (Reason)
*Thinking = affirming and negating
Doubting=thinking
COGITO ERGO SUM
- Latin
- Act of thinking = I/self = mind/mental entity
- Cannot be body = sense perception
- Foundational principle
- What truly exists is the mind/self
- Existence of self/real
*Clear and distinct - the more you doubt, the more you affirm it
*Independent - universally true in all human minds
*Existence - must pertain to the existence of self/mind
“I” (mind/cogito) - thinking, ideas, free will, (choice/decision), soul (spiritual soul that can exist independently in the body)
REVERSAL OF DOUBT
- replace doubt with certainty
- Prove other truths->mind and body
- Must investigate features of the mind
- Rebuild and reprove everything from the standpoint of Cogito
*Self - abstract/can exist out of body
SUBJECTIVISM (P.99)
- I can only know with certainty = my own mind and my thoughts [mind + ideas about reality]
- Viewpoint — truth=> mind and our thinking
- Everything outside the mind is uncertain
2 MAJOR IMPLICATIONS OF SUBJECTIVISM
- Knowledge of things outside the mind — mind and/or self -> basis for reconstruction
- If mind is certain, outside the mind is uncertain; mind is detached from social world/human beings/physical nature
- find not your own person - own standpoint
- Break away from social norms
Solipsism
- only the self exists and the ideas -> tries to prove material bodies
- Enclosed standpoint
- To overcome, other things exist along with the existence of the mind
- My mind with its thoughts it the only thing that exists, the only reality
Test of Truth
- self-evidently clear and distinct in the mind for it to be true
- “Mathematics” X God
- Prove there is a God to prove Mathematics->material world
- Mathematics - universally true
- Reconstruct God based on reason and logic
THEORY OF IDEAS:
- idea: a concept which we are conscious of; definition of things
- 3 types of ideas:
- Innate
- Naturally born with
- Mathematics, logic, God (perfect Supreme being)
- Self-evident to human reason
- Descartes agrees, from human reason and clear and distinct
- Factitious/Fictitious
- Human imagination
- Futuristic world
- Adventitious
- Caused by sense experience/outside human mind ->sense perception
- Buildings, trees
*factitious and adventitious = illusion and sense perception
- Ideas have 2 kinds of realities [function/objectives]
- Actual/Formal Reality
- Presence of ideas in the mind/the definition of an object
- Ideas not found outside the mind; all definitions are in the mind but not all are clear and distinct
- Objective Reality
- Ideas refer to objects
- Functions of ideas in reference to outside of mind
- Correspondence of ideas to external objects
- Natural function of ideas (hierarchical)
*”7”- what makes 7 a 7 — actual reality [concept]
- idea + objects — objective reality
*For something to exist outside the mind, it should be clear and distinct
THEORY OF CAUSES (p.103)
“All ideas are the effects of causes => all thing do not happen out of the blue
3 Self Evident Propositions about Causes
- There must be as much reality in the cause as in the effect
- Something cannot come from nothing
- must come from certain explanation/thing which is real
- What is perfect cannot proceed from the imperfect
- concept of perfection must come from something perfect
Cause and Effect
- nature of cause should be the same as the nature of effect
- Not merely a connection
DESCARTES RATIONALISTIC PROOFS FOR GOD
- First Proof (p. 105) “Doctrine of Ideas”
- God is the cause and we are the effect
- CRITICISMS:
- Ludwig Feuerbach
- “God is a projection of the human mind”
- Create “perfect being”/ false illusion to escape imperfections of the world
- Perfection is manmade
- Postmodernism
- Criticizes modern structures/idea of humanity
- Concept of perfection => social construct
- Perfection makes us stagnant, limited in our lives
- Assumes that the “innate idea of God is universal” but it is relative
- Second Proof (p. 106)
- I cannot be the cause of my own existence
- Infinite regress - other selves cannot be the cause of our existence [no starting point]
- God - first uncaused cause which makes Cogito exist [1st uncaused cause = matter/energy]
- Process of elimination
- Third Proof (p. 107)
- ontological argument
- Developed by Saint Anselm
- Definition/idea of God as a perfect being -> prove existence -> investigate God as a perfect being
- Political reasons in personal life (Galileo excommunicated)
- Appease the church
- Extra proof to be politically correct
- If God is complete and perfect, then He must exist Proves God through the definition of God
- God exists because He is conceptualized as a perfect being
- To be perfect is to be complete
- A perfect being must have the attribute of existence
AFTERMATH OF PROVING GOD
- God is the ultimate cause of the “self”
- the reason we exist is because of an ultimate creator
- On “human error” — misuse of “free will”
- human mistakes is not based on God
- Free will -> arbitrary, can mislead you from the truth
- God as the basis for the ideas of Math and logical reasoning
“Can the mind be the cause of the idea of a material body?”
Idea of material bodies X mind; X free will
*God cannot be the cause of physical things - God-> all good nature-> idea must come from actual material bodies
“Clear and Distinct” and “Objective”
- objective: exists independently from the human senses
Primary Qualities
- Size and shapes/^^figures^^
- Capacity for ^^motion^^/change [motion based on human reason]
- Volume and space/^^spatial extension^^
*thorough understanding of math/geometry, you will have a thorough understanding of the world.
DESCARTES’ VIEW OF THE UNIVERSE
- Theory on Mechanism (pp. 117-118) -> scientific view of the universe
Clockwork Universe
- infinite extension
- Constant motion
- ^^Physical World^^: works like a clock, determined
- ^^Animals^^: matter in motion; operate on instinct than free will
*Conscience, human reason, and free will sets humans apart from animals
