  • Substance Dualism
    • Plato
      • The soul, unlike the body can't be destroyed
        • BC it doesn't have parts
        • Change involves something coming about from the opposite.
          • becoming alive = change from not being alive
          • Alive = Soul joining the body T/F soul must've existed pre-life
            • T/F soul = separate substance to the body
      • Change involves something coming about from the opposite.
        • becoming alive = change from not being alive
        • Alive = Soul joining the body T/F soul must've existed pre-life
          • T/F soul = separate substance to the body
    • Descartes
      • A/Divisibility
        • The body is divisible into parts. The mind is not divisible into parts. T/F the mind and body must be logically distinct.
          • Thought = the essential property of mind bc it has NO SPATIAL LOCATION
            • However, this means that the mind is presupposed to exist b/c it has properties
          • INCOHERENT b/c consciousness = mental state NOT a physical object
          • If the mind is intimately connected to the brain there is a possibility IT COULD BE DIVISIBLE
      • I can doubt that my body exists. I cannot doubt that I exist. T/F I am distinct from my body
        • Descartes has not shown that his mind exists as a substance
        • You can't legitimately infer, from the conception of a mind's existence, that the mind and body are different things
          • EXEMPLIFY USING MASKED MAN FALLOCY
    • A substance is something which can exist independently of anything else
      • Dualism states that there are 2 types of substance; MENTAL & PHYSICAL
    • the idea that the mind and body are 2 DISTINCT LOGICAL SUBSTANCES
  • The body is doubtable through the POWERFUL DEMON analogy
    • Your existence is undoubtable b/c doubting your existence is confirmation that you exist
      • I can doubt that my body exists. I cannot doubt that I exist. T/F I am distinct from my body
        • Descartes has not shown that his mind exists as a substance
        • You can't legitimately infer, from the conception of a mind's existence, that the mind and body are different things
          • EXEMPLIFY USING MASKED MAN FALLOCY
