Theme 1A: Inductive arguments - cosmological Flashcards
What does the cosmological argument attempt to prove?
That God is the cause of the universe
What type of argument is the cosmological argument?
Inductive
Posteriori
What does inductive argument mean?
Probability not proof, even if the premises are true the conclusion can still be false
what does posteriori mean?
Based on experience not logic
What is the cosmological argument based on?
It is based on our experience that everything has a cause - posteriori
What does the cosmological argument presume?
That the universe must have a first cause - priori
Why is the cause of the universe a external cause?
As it must be located outside of the universe
What are the key facts about the external cause in the cosmological argument?
- Not itself cause
- Doesn’t need an explanation
- The external cause is God
- God’s existence is necessary
Who came up with the 5 ways of the cosmological argument?
Thomas Aquinas
What is the name of the book that Aquinas wrote the cosmological argument in?
Summa Theologica
What is Aquinas first way referred to as?
‘Motion and change’
What is the first way?
- Everything in the world is in a state of change or motion
- When we look down the changes we would have to come to something that started the sequence off
- At the start of the sequence there must be an unmoved mover
- Aquinas called this God
Who was Aquinas influenced by for the first way?
- Aristotle’s idea of a prime mover
- He used Aristotle’s examples and explanations
What was Aristotle’s idea of a prime mover (first way)?
- Aristotle uses things moving from a state of potentiality to a state of an actuality
- There must be an efficient cause that moves potentiality to actuality
What did Aquinas believe about infinite regress?
- He rejected it
- He believed we would not find the first cause of things by simply going further and further back in time
- He said there must be a beginning point
What is infinite regress?
Finding the first cause of things by simply going further and further back in time
What was Aristotle’s analogy that can be used to illustrate the first way?
- The example of a block of marble
- The block has the potentiality to become a statue (actuality) but only when acted on by the sculptor (efficient cause)
- The universe is the same
What was Aquinas analogy that can be used to illustrate the first way?
- The example of wood
- Wood has the potential to become hot but it needs actual heat to do so
- An efficient cause (fire) must cause the wood to become hot.
- The universe is the same
What concept does the second way deal with?
Cause and effect
According to Aquinas, what is controlled by the law of cause and effect?
Everything observable in nature
What is the second way based on?
efficient causality
How do we see efficient causality in the world around us?
As there is an order of efficient causes and it is impossible that something is its own efficient cause
What can the order of efficient causes not do (second way)?
Cannot proceed to infinity
What is the second way?
- Everything has a cause as nothing can cause itself
- There can’t be an infinite number of causes as with an infinite chain there can be no first cause
- Therefore there must be a first cause on which all other things depend on
- Aquinas called this God
