Cosmological argument

View mindmap
  • Cosmological argument
    • Summary
      • Developed by Aquinas
      • A posteriori     Synthetic      Inductive
      • Based on observation of the world
    • 1st Way- MOTION (kinetological)
      • Everything in the world is moving or changing. Nothing can move or change by itself. There cannot be an infinite regress of things changing other things. Therefore there must be a Prime Mover (or changer). This is called God
    • 2nd Way- CAUSATION
      • Everything in the world has a cause. Nothing is the cause of itself. There cannot be an infinite regress of causes. Therefore there has to be a first cause to start the chain of causes. This first cause we call God
    • 3rd Way- CONTINGENCY
      • P1) Everything has a cause P2) Nothing is its own cause       P3) Chain of causes cannot be infinite      P4) Must be a 'first cause' C1) This is God
      • Reductio ad absurdum
        • P1 and P4= contradiction
          • Therefore logical to reject P1 and accept P4
            • Otherwise P3 and C wouldn't link
    • Coppleston
      • 1) There are things in this world that are contingent – they might not have existed 2)Everything depends on something else for it's existence      3)Therefore there must be a cause of everything in the universe that exists outside of it   4)This cause must be a necessary being                5)= God
      • Fredrick Copleston reformulated Aquinas' argument by concentrating on contingency. He proposed his argument in a BBC radio debate in 1947
