- Together, law and science can create evidence
Why do we need to study knowledge? (PLATO)
- If we believe based on what others tell us, how can we know our sources are accurate and thus our beliefs are accurate?
- Knowledge is not social
Why study knowledge? (Phantom Limb Problem)
If our beliefs are based on sensation, how do we know our sensations correspond to reality?
Senses are decieved - therefore they are not concrete
- We cannot claim to have knowledge because there is no way to confirm that our beliefs are actually true.
- We cannot prove correspondance is necessarily true
Is skepticism self defeating?
How do we KNOW we cannot confirm the truth of our beliefs?
Rationalism believs knowledge..
- Comes from mental insights into the true nature of reality.
- It is either innate to the mind, or proceeses innate ot the mind lead to knowledge
- - PLATO, DESCARTES, KANT
- knowledge comes from sensation
- -LOCKE, HUME

Descartes concluded that our existence as thinking minds is known..
- we cannot doubt it without contradiction
Descartes beleived that knowing melted wax is the same wax as a candle was showing
- the view that our beliefs map the true properties of the mind independent from reality
- Maybe the devil plants these ideas in us so that our ideas of time are not true of reality
- Knowlede is only in things that are certain
- Cast doubt on all of them
- Our senses fool us
- Logic could be true, but evil could plant these ideas
- So, if it can be knowledge, it can be doubted as therefore isnt a stable foundation for knowledge
Meditation 2 - Descartes
- As I doubt, I cannot doubt myself
- I think therefore I am
- Soul is immarterial
- I can doubt the existence of material things
- I cannot doubt my soul
- Therefore I am immaterial
Meditaiton 3 - GOD EXISTS
- I have the ideas of perfection
- I am not perfect
- Therefore this idea must have come from outside of me
- Not from nature- it's imperfect too
- Must come from being who is perfect
- God is perfect
Meditation 4 - TRUTH AND ERROR
- God is not the deciver - he'd be imperfect
- My soul can have knowledge/will
- Knowledge is limited
- Will is not limited
- Judgement is an act of will people choose to believe is true
- Error is judgement where will is free and what they believe isnt supported by knowledge
Meditation 5 - AREAS OF REALITY
- Res cogito: innate ideas
- Res extensia: world of space/time
- Imagaination: Combo of ideas and the world of space/time
Innate ideas are necessarily true because they cannot be changed at will
- Idea of God is perfection
- What does not exist is imperfect
- God, exists
- He isnt a deceiver -imperfect
- So innate ideas, are not product of deceiving god,
- so they must be true
- I am not made of immaterial because I can take sense perception and form ideas from it
- Ideas come from outside the soul
- My body exists
- So my sense genuine point to an independent existing material world

- Senses convey out perceptions
- Our opinions shape our thoughts -REFLECTION
John Locke Book 8
- Original qualities of the body observe to produce simple ideas
- Secondary qualities - Powers to produce various sensations
