Final Exam: Philosophy of Religion Flashcards
What are the four attributes of Aquinias God?
Is there a problem with those?
- Omnipotent (all-powerful)
- Omniscient (all-knowing)
- Omnibenevolent (all-good)
- Personal
Logical problem: omnipotency
can God make a stone so heavy that he cannot lift it? (double-bind) if yes and if no, his power is limited
What are Aquinas 5 arguments for God’s existence?
- Motion
- Causation
- Contingent and necessary beings
- Properties in degrees
- Design
How does Aquinas first argument work?
- Some things move
- Any movement requires a cause
- The cause must be before the movement
- There are no infinite chains of movement
- There must be a first cause of movement
- It has to be outside of the natural world
- Therefore, God exists
How does Aquinas second argument work?
- There are events
- Events have causes
- Causes must preceed their events
- There are no infinite chains of events
- Therefore there must be a first event
- This event also must have a cause, but this cause cannot be another event in the natural world
- Therefore, God must have caused the first even and must exist.
What are the problems of Aquinas first two arguments?
- Premises are questionable
- Motion: Aristotles physics vs. Newton’s physics
- Birthday Fallacy
- Everyone has a birthday, therefore there must be one day that is everybody’s birthday.
- Is backward causation impossible
What are contigent and necessary truths?
- Contingent truths = truths that are true in at least one possible world
- Necessary truths = truths that are true in all possible worlds
- Possible worlds = all worlds that are (theoretically) possible; worlds that could exist
How does Aquinas third argument work? What type is it?
Reductio ad absurdem argument
- Suppose all beings where contingent
- Contingent beings come into existencs and stop existing somewhen
- If all beings were contigent, there must have been an empty time
- This empty time would have been in the past
- Then the world would also be empty now
- The world is not empty now.
- Therefore there must be a non-contingent being and that being is God
What are some of the problems of Aquinas third arguemt?
- nearly all of the premises can be doubted
- Empty time:
- birthday fallacy
- why in the past?
- Non-contigent being: why must it be God?
- Why cannot an empty world generate things?
- etc.
- Empty time:
What are a priori and a posteriori truths?
- a priori = can be known simply by use of concepts without experience or observations
- a posteriori = can only be known by experience or observations
What does “act for an end” mean?
- it means to have a function or a goal
How does Aquinas Argument from Design work?
- Aquinas, like Aristotle thought that everything acts for an end. E.g. a falling stone tries to get close to earth.
- Argument
- Some things which have a function or act for an end have minds
- Any such thing, which does not have a mind must have been designed by an intelligent designer
- Therefore there is a designer, who created all those things
- Therefore God exists
How can we critize Aquinas argument from design?
- Birthday fallacy: one designer created them all
- Sober: abductive argument
- What about H3: Evolution?
What is Paley’s watch?
- suppose you find a watch on the beach
- What is more likely?
- H1: The random movements of sand, water and wind created this sophisticated masterpieve
- H2: An intelligent designer created the watch
- Surprise principle favours H2 over H1
- Argument by analogy –> same applies to our world
What is an argument by analogy?
What are its components?
What determines its strength?
- An argument that shows one feature and tries to portray this feature on something similar
- Components
- Analog = Thing with feature
- Target = target of analogy
- Strengt depends on similarity of analog and target. Higher is better, but if identical its useless.
What is Hume’s criticism of Paley’s Watch argument?
- Watch is overall not very similar to universe
- Watch is overall not very similar to biological organisms
- Even if argument would be better, it would only conclude that there exists a being “intelligent enough”, does not prove God’s existence
