  1. 1Define realismThe claim that there is an external world
  2. 2Define direct realismThe claim that we are immediately aware of a real external world
  3. 3Define indirect realismThe claim that our perceptions are representations of the real world
  4. 4Define mind independentX exists regardless of whether it is perceieved
  5. 5Define mind dependnetX only exists so long as it is percieved
  6. 6What is sense dataThe direct object of perception (IR)
  7. 7What are primary qualitiesthose which are inseperable from the object - relative position
  8. 8What are secondary qualitiesqualities which produce ideas upon perception - such as colour
  9. 9Argument for DRcommon sense
  10. 10Argument of perceptual variationI see an object
    the object does not change
    as i approach the object my perception does, therefore i cannot be perceiving the object directly
    begs the question - there is a change in relational properties
  11. 11Argument of illusionI am directly aware of X (an illusion)
    X is not physically true
    therefore I am directly aware of something non-physical
    perceptual experience is the same regardless of illusion
    therefore the cause is the same
    therefore i am directly perceiving the non physical - SD
    but 1 and 2 contradict, relationsal properties also resolves this
  12. 12Argument from hallucinationWe perceive objects
    we can hallucinate objects
    those which are hallucinated are MD
    perception is same regardless
    explanation is the same
    all perception is MD
    if this were true there would be no semantic distinction
  13. 13Time lag argumentwhen one looks at a star they are looking millions of years into the past
    the star may no longer exist #therefore one cannot be directly aware of the star if it no longer exists
    relational properties
  14. 14What are the two claims of IRMI exist
    we are indirectly, but accurately, aware of them
  15. 15IR Argument that MI exist - Locke and RusselLocke - perception is uncontrollable - we are not the cause - Mi is the cause
    What about demon doubt?
    Russel - Same as abover but MI is likely cause, more likely than demon
  16. 16IR argument that our perceptions are accurateLocke - we are accurately aware of an objectis primary qualities - size, we are unsure about secondaries
    Russel - we are only truly aware of relational properites, that is all
  17. 17Issues for IRDissimilarite betweeen MI and MD - consistent/inconsistnet - representing eachother seems incoherent
    cuasal issues - how does the physical cause the non-physical
  18. 182 claims of idealismWe are immediately aware of MD
    Only MD exists
  19. 19Arguments that we are immediately aware of MD only (Not PQs)Relativity - all pereption is variable even if the object is not
    Abstraction - one cnanot concieve of an objecti without SQs, they are necessary for the object and as they are MD so is the object
    Resemblence - MD and MI are entirely different so it does not make sense for one to represent the other
  20. 20Argument that only MD exist - master argumentIf MI exist they do so independent of perception
    they can exist without ever being concieved
    we cannot concieve of an objecti without concieving it though such action
    therefore MI cannot eixts independent of thought
    therefore all MI are MD, thus MI do not exist
  21. 21Issue with the master argumentcontradiction in terms - perception and conception are not synonomous
    conclusion is unjutified - ambiguous at best
    reducible to absurd - objects cease when not experienced
    one can conceive of the unconcieved without conceiving the specific
  22. 22Issues for idealismsollipsism
    illusion and hallucination
    space and time
    reliance on god
  23. 23Sollipsism issueall that exists is my ecperience - uncomfortable but not damning - i do not perceive my mind, it does not exist
    the mind is that which can perceive, i can perceive, i must have a mind. if i have one others could exist, as i do not control my perception they must originat from another (gods) mind
  24. 24Illusion and hallucnination issue for idealismillusion and hallucination are just as accurate as "reality", this is not what we mean by usie of these terms
    also entails that god is a deciever
  25. 25space and time issuetwo people perceive the same tree differently, there is no tree but 2 different trees
    there is no objectivity in idealism, no right and wrong synthetic knowledge
    secured by God
  26. 26issue of GodGods existence reolves most previous issues but with illusion and hallucination one must concede god is a deciever
    also gods existence is not certain
