Arguments From Observation Flashcards
What is Aquinas’ first way? Reasoning?
- All things are in a state of change.
- Everything is a secondary mover.
- If all things are secondary movers then there must be infinite regress.
- If the above is correct then there is no Prime Mover. Without a Prime Mover, there can be no secondary movers, therefore, the point above is false as infinite regress is impossible. (The reductio ad absurdum technique.)
- Therefore, there must be a prime mover. This we call “God”.
What is Aquinas’ second way?
- There is an order of efficient causes.
- No efficient cause can cause itself.
- If there is infinite regress then there is no First Cause.
- If the point above is true then there can be no subsequent causes. Infinite regress is impossible. (The reductio ad absurdum technique.)
- Therefore there must be a first cause of everything. This we call “God”.
What is Aquinas’ third way?
(1) Things are contingent.
(2) If everything is contingent, there must have been a time when nothing existed.
(3) Therefore (using reductio ad absurdum) nothing can come from nothing.
(4) Therefore, there must be a necessary being.
(5) Every necessary being must have a cause either inside or outside of itself.
(6) Imagine every necessary being had a cause outside itself.
(7) Therefore (using reductio ad absurdum) if (6) is true, then there is no ultimate cause of necessity.
(8) Therefore, there must be a necessary being which causes and contains all other necessary and contingent beings. This being we call “God”.
When was Aquinas alive?
1224-1274
What is the issue with infinite regress for Aquinas’ argument?
Why can’t we have one? For example the theory of the Big Bang has variations that look at rebound universes that would allow for infinite regression on a universal scale. It is a logical leap to say that a Prime Mover makes more sense than an infinite regress - it is either that or the limitations of human thought.
How is there an issue with the image of God? (cosmological)
It does not prove the god of classical theism, only a first cause that could be anything. A monolith a pantheon etc.
What is the issue with God being the exception? (cosmological)
Could the universe not be the exception? The uncaused causer.
How does Quantum physics lead to a lack of causation? (cosmological)
Quantum particles do not always have causes for their wave function collapses, theories such as Schrödinger’s for example allow for this.
What is the issue with infinite regress for contingency?
Why can’t there be overlapping contingent beings going back to infinity? This is a fallacy.
Criticism about the point of cosmological arguments?
Is there a point in knowing what caused everything, this does not aid us on a day to day level.
What is Hume’s first criticism of the cosmological argument?
Just bc we can observe cause and effect in the universe does not mean that this rule applies to the universe itself….The Fallacy of composition…what is true for the parts is not always true for the whole.
This is the fallacy of affirmation and consequent.
How does Mackie agree with the criticisms by Hume of the cosmological argument?
Why should people accept that God is a necessary being?
He argued that there is a ‘permanent stock of matter whose essence did not involve existence from anything else’
How can we criticize the cosmological argument through its language? Who said this?
Analytical and Synthetic statements (reason- true by definition….or you need to prove the statement with outside information)
Bertrand Russell said that only analytical statements are necessary not any being such as God. This is bc a being is not self-explanatory and therefore evidence must be found exterior to Aquinas’ reasoning.
What is the issue with trying to explain things with the cosmological argument?
Why are we looking for an explanation of the universe and not an explanation for God. Why can’t the universe be the unexplained reason for our existence?
What scientific theories should you use to criticize the cosmological argument?
- the big bang (+ rebound universes)
- types of infinity
- steady state theory (Bondi, Gold and Hoyle…energy cannot be created…entropy etc)
- Quantum mechanics
- Background radiation
- Red shift
(Remember some of these are just theories)
What is Leibniz’ defense of the cosmological arguement?
The argument from sufficient reason.
Everything in the world is so amazing and the cause can be no greater than the effect. The effect is amazing and so must be the causer.
What is Copleston’s support of the cosmological argument?
Contingency…objects in the world depend on something for their existence therefore what caused everything in the universe must be external to the universe. And this being must be self-explanatory and ‘necessary’, giving the definition to everything else.
What is Russel’s quote that demonstrates the fallacy of composition?
“every man that exists has a mother…therefore the human race must have a mother”
What is Hume’s second criticism of the cosmological argument?
We can talk about things we have done ourselves with certainty but we have no knowledge of creating the universe and therefore cannot make assumptions about it. There being a cause of the universe can be neither proven nor established.
What is Hume’s third criticism of the cosmological argument?
Even if we accept God as the first cause we cannot prove that it is the classical God of theism. It could actually be a pantheon or a monolith.
This is an inductive leap as it does not link with the premises. We cannot conclude from speculation.
What is a fallacy of composition?
a mistaken belief based on unsound reasoning that makes that argument invalid.
What is Hume’s twenty particle explanation of the cosmological criticism?
If you find an explanation for the particle individually it would be wrong to then reason the function of them as a collective. Knowing everything about bosons, neutrons etc…cannot tell you it is an organ.
How can Aquinas be linked to Aristotle?
The process of going through the stages of actuality to potentiality. This is the form of motion that draws us towards our telos and so fits with the first way.
What is a Cosmological Argument?
A classical argument for the existence of God, it is based on a belief that there is a first cause behind the existence of the universe
What kind of reasoning is the Cosmological Argument?
A posterior - it derives the conclusion that God exists from a posterior premise because it is based on what can be seen in the world and the universe
What kind of reasoning is the teleological arguement?
A posteriori - we are looking to the world for evidence of purpose
What is design qua purpose?
The world has patterns and organisation in it
Everything is designed for a purpose otherwise it would not have been designed in the first place
Anything that is designed must have a designer
How does Pailey account for evil in the world?
Even if a watch is not working it still shows evidence of design
How is Paley making a logical leap when comparing the eye to the world?
They are not really comparable, much like the conclusion of Hume’s house analogy, we can see the workers or the dna that have made up these structures…but we cannot make that leap as we cannot see the makers of this universe.
How does Paley link the watchmaker to God?
Nature must have the highest complexity, perfection and skilled of designers because it is the most complex of all designs
What is the order of Paley’s argument?
- design qua purpose
- the watch analogy
- reasoning towards God
- design qua regularity
Aquinas quote about design?
Everything operates as to a design. This design is from God.
Which if Paley’s arguments fits with Aquinas’ views?
Design qua regualarity
How does Aquinas reason the presence of design qua regularity?
- objects follow natural laws, have a telos
- when something works efficiently this is bc they have been designed
- everything designed must have a designer
- arrow analogy, everything that cannot think for itself in the natural world must be directed
- This is God
Dawkin’s quote from the blind watchmaker about teleology?
No purpose, no evil and no good, nothing but blind and pitiless indifference.
What is Hume’s second argument against teleology?
The Epicurean thought hypothesis…
If we accept there is design…but that we cannot know what God is
At the begging of the universe time particles were in chaotic, random motion and evolved into an ordered system….therefore design happened over time - not via a designer. (2nd law of thermodynamics?)
