Cosmological argument Flashcards
What is the argument based on?
The idea that all things in the universe are contingent and do not explain within themselves the reason for their own existence, so must need something necessary to explain them.
Explain Leibniz’s principle of sufficient reason
- Nothing takes place without there being sufficient reason for it. 2. As everything in the world is contingent, to have sufficient reason, we must get back to something that is not contingent. 3. This non contingent sufficient reason must exist outside of the world and the best explanation for it is god.
Describe the background to the kalam cosmological argument
It was developed by 11th century Islamic scholastics al ghazali and was re-examined and updated by 20th century American philosopher William Lane Craig. It argues from the existence of the universe to the existence of god.
What are the four premises of the kalam argument
- Everything that began to exist has a cause. 2. The universe began to exist. 3. Therefor, the universe has a cause. 4. The cause of the universe’s existence must be god. This is a deductive argument which argues from the general to the specific.
Explain Craig’s use of the second law of thermodynamics
- In an isolated system the state of entropy (the amount of unusable energy available) increases with time and never decreases. 2. The universe of the past had a much lower entropy then it has now. 3. A universe which has existed forever could not be now in the present state of disequilibrium. 4. Ergo, the universe began to exist.
What is Aristotle’s cosmological argument?
- Either the universe had an ultimate cause, or the universe had no ultimate cause. 2. If the universe had no ultimate cause, then the chain of cause and effect had no beginning. 3. This is impossible, if the chain of cause and effect had no begging, there would be no chain. 4. Ergo, the universe must have an ultimate cause. This is an example of a Reductio ad absurdum argument.
What is the main problem with the Kalām argument?
It supposed a cause which comes into existence with no cause, how did the universe begin, what is its cause? Modern astrophysics suggest this is the Big Bang.
What are the names of aquinas’ cosmological arguments?
From motion, from cause and from contingency. They are inductive arguments which use Reductio ad absurdum to disprove the idea of infinite regress.
What are the four premises of From Motion?
- There are things in the universe in a state of motion. 2. Nothing can change by itself, they are all secondary movers. 3. If all things were secondary, there would be an infinite regress of movers. 4. If this is true, there would be no first mover, so no secondary movers. C. There are secondary movers, so there must be an unmoved first mover.
What are the four premises of From cause?
- Every event has a cause. 2. Nothing can be its own cause. 3. If the order of causes goes back to infinity, there would be no first cause. 4. If there was no first cause, there would be no causes at all, this is false. C. There must be a first cause, god.
What are the first three premises of From contingency?
- In nature, everything can exist or not. 2. Given infinite time, everything will eventually not exist. 3. If there was once nothing, nothing could come from it.
What are the last three premises of From contingency?
- As something could not come from nothing, there must be something which necessarily exists. 5. Everything necessary must be caused or uncaused. 6. You can’t have an infinite series of necessary things causing each other or there’d be no explanation for the series itself. C. There must be a being which has its own necessity, god.
Give four strengths of aquinas’ argument
- It does not seek to prove a uniquely Christian god, just an uncaused necessary being. This makes its more simple and easier to prove. 2. Inductive arguments are based on probability and our experiences of the world seem to support the argument, raising its probability. 3. Cosmological arguments are supported by scientific arguments like the big bang which argue that the universe had a beginning. 4. Even if an infinite regress was possible, we would still suppose it had an explanation outside of itself.
Give three weaknesses of aquinas’ argument
- Inductive arguments are only probable and do not prove the existence of god. 2. Why does infinite regress have to be impossible? 3. If we think about what god was doing before he chose to create the universe, we are drawn into an infinite regress where god actively chose not to create the universe.
Give three points Hume made against the argument
- We have no experience of the creation of the universe, so can’t speak meaningfully of it. 2. Even if the universe did begin, there is nothing to prove that it was god who caused it. 3. Sufficient reason is flawed, those looking for a sufficient explanation for the universe are looking for something that does not exist.
