Challenges to the existence of God COPY Flashcards
Outline the fundamentals of the cosmological argument
-Every effects has a cause. -Universe=effect, has a cause=God. -A posteriori inductive-based on evidence in nature, accepting premises leads to a probable but not necessary conclusion.
Outline the classical cosmological argument
-We can observe that things move/change. -From observation-easy to see things come in to existence/cease to exist. -Cosmology seeks to prove that everything in the universe has a cause-universe in itself has a cause=God.
Outline Aquinas’s 5 ways-summa theologica
Cosmological argument
- Change- things reach potential through external influence- fire makes wood hot, wood has potential to be hot, external influence=fire makes wood hot-wood reaches its potential=hot.
- Cause & effect- Aquinas observed C&A in the universe-nothing can cause itself-would have had to exist before it existed=illogical-rejected infinite regress-must be a first uncaused cause (God). rejection of infinite regress later supported by Leibniz in principle of sufficient reason-must be sufficient reason that explains the cause of the universe.
- Contingency- if there was a time when nothing existed-nothing would still exist as nothing can bring itself into existence-cause of universe must be external to it-must be a necessary being to have always existed.
Outline Aristotle and the prime mover
Cosmological argument
-All movement depends on a mover existing-behind every movement is a chain of events that brought about the movement-must be a common source of all substance that exists necessarily. -Movement is about change- therefore must be an ‘unmoved mover’(prime mover)-because without one-no chain at all.
Outline strengths and weaknesses of Aquinas’ and Craig’s cosmological argument
Strengths: -Value for religious faith: argument based on natural theology-knowledge of god is by using reason alone means no need for special revelation experiences seems convincing.
- May not be in itself sufficient proof for gods existence but along with other arguments (teleological, bible) it is.
- Based on observable evidence-motion/change, cause/effect-more persuasive- Modern versions-Craig-uses science as evidence.
- Big bang supports Craig’s 2nd premise-universe began to exist- logical to accept universe has a logical starting point.
Weaknesses:
- We don’t have to reject infinite regress.
- Idea of God being an uncaused causer can be criticised-doesn’t follow logic of argument- but Aquinas said in response God is unique-doesn’t need anything else for existence.
- Just because things in universe appear contingent doesn’t mean the universe is also contingent.
- Hume states maybe the universe didn’t have a cause since we have no experience of universes being caused so never able to say with certainty- Black Swan arg.
- Quantum physics weakens CA-shows that some movement does not require a set of causes-particles of gas.
Outline the premises of the teleological argument
-A posteriori inductive- based on external evidence, accepting premises leads to a probable not necessary conclusion. -Teleos-greak for end/purpose. P1. all complex/intricate objects require intelligent designer. P2. world/universe=intricate object. P3. Must require an intricate designer. C: intelligent designer of universe is god.
Outline Thomas Aquinas’ design argument
-In book ‘summa theologica’ to strengthen Christian faith. -Believed we can know God through revelation-apparent in the Bible & faith in God. -5th way: Nothing inanimate is purposeful without the aid of a ‘guiding hand (bow/arrow no purpose without guiding hand to fulfil purpose). -2 elements of natural world that show its been designed by an intelligent designer. 1. Order in the universe. 2.order is beneficial.
Outline F.R Tennant’s Anthropic principle as a development of the teleological argument
-Developed in book ‘Philosophical theology’. 3 types of natural evidence in the world in favour of a designer. -1. the world can be analysed in a rational manner. -2. the way inorganic world provided basic necessities required to sustain life. -3. evolution leading to intelligent human life. Claims it would be possible to imagine a chaotic universe where no rules applied but universe isn’t chaotic-designed in which intelligent human life could exist-human life is therefore a culmination in current stage of Gods plan.
Outline the Aesthetic argument as a development of the teleological argument
-Humans posses ability to appreciate beauty of surroundings e.g. art, music but isn’t necessary for survival/development of life. -cannot be a result of natural selection alone.
Outline Paley’s teleological argument
Argued for intelligent designer with two arguments:
- design qua (in relation to) purpose: uses watch argument-Two features of watch reliably indicate its result of intelligent designer, not chance-performs function valuable to intelligent agent-couldn’t perform function if parts sized/arranged differently so some intelligent designer must have designed it-these characteristics endow watch with functional complexity -relate this to the eye-like many things in universe is too complex to not have an intelligent designer.
- design qua regularity: Evidence from astronomy-rotation of planets in solar system & how they obey same universal laws-gravity- couldn’t have come about by chance=external agent must have imposed order=God.
Evaluate Aquinas’ teleological argument
Strengths: -Appears logical universe had to come from somewhere. -Argument open to all, not just religious people. Weaknesses: -Evolution an explanation for design, Charles Darwin wrote in 1859-long after Aquinas-why does the designer have to be God-who designed the designer.
Outline the foundations and premises of the ontological argument
-A priori deductive-works from principles and definitions to pove existence of God, if premises accepted leads to a necessary conclusion.
P1 God is that which nothing greater cane be conceived or the mot supremely perfect being
P2 a real existent being would be greater than an imaginary being
P3 therefore the concept of God is surpassed by an actual being
C God must exist in reality to be the greatest being possible
Outline the 1st part of Anselm’s formulation of the ontological argument
- Formulated argument from perspective of ‘faith seeking understanding’ rather than to convert people to faith.
- Set in book Proslogion.
1st part (proslogion 2):
Defines god- that to which nothing greater can be conceived.
- Refers to Psalm 14:1,53:1 “there is no God”-seeing absurdity of the fools position as there is a contradiction as if athiests understand the defintion of God, they must accept his existence.
- Makes distnction between ‘in ones understanding’ and ‘to understand’ that object exists.
- Anselm said if God exists in intellectu (the mind) then a greater being can be conceived which would exist in reality=G therefore exists.
Define reductio ad adsurbum as part of Anselms ontological argument
The contradiction of the definition of God as to say a ‘greater God is possible’ would be absurd, therefore the opposite must be true=God must exist.
Outline the 2nd part of Anselms formulation of the ontological argument
Says Gods existence is necessary
- P1 ‘God’ = greatest being we can possibly imagine
- P2 greater to be a necessary being than a contingent being
- P3 God only existing as a contingent being , would be possible to imagine a greater necessary being
C1 god has to exist necessarily, thus it is impossible to imagine god not always existing
