Aquinas' Three Ways

  1. What are the first two premises for Aquinas' First Way?
    • 1.) We can observe that things in the world are in a process of motion
    • 2.) Everything that is in motion is in the process of changing from a potential to an actual state
  2. What are the last three premises for Aquinas' First Way?
    • 3.) A thing cannot be at the same time potentially and actually the same thing.
    • 4.) So everything that is in motion must be put into this state by another thing.
    • 5.) So the chain of movers 'cannot go on to infinity, because then there would be no first mover, and consequently, no other mover.
  3. What is the conclusion of Aquinas' First Way?
    It is necessary to arrive at a first mover, put in motion by no other; and this everyone understands to be God.
  4. What is an example of Aquinas' First Way?
    If something is actually hot, it cannot be potentially hot, but it can be potentially cold.
  5. What are the first two premises for Aquinas' Second Way?
    • 1.) Nothing is an efficient cause of itself.
    • 2.) Efficient causes follow in order: a first cause, a second cause, a third and so on.
  6. What is the third premise for Aquinas' Second Way?
    It is not possible for efficient causes to go back to infinity, because if there is no efficient first cause, there will not be any following causes.
  7. What is the conclusion of Aquinas' Second Way?
    It is necessary to admit to a first efficient cause to which everyone gives the name of God.
  8. What are the first three premises for Aquinas' Third Way?
    • 1.) Everything within the universe corrupts - goes in and out of existence.
    • 2.) So there must have been a time when there was nothing in existence.
    • 3.) But nothing can come from nothing.
  9. What are the last three premises for Aquinas' Third Way?
    • 4.) If there once was nothing, there would be nothing now, which is absurd.
    • 5.) So there must be a necessary being on whom all existence depends.
    • 6.) This necessary being we call 'God'.
  10. What is an example of Aquinas' Third Way?
    The Dodo existed continently, it is now extinct and the universe continues happily without it.
