God's existence - a posteriori Flashcards
a posteriori arguments
• Inductive arguments - they reach conclusions which are statements of probability rather than conclusive proofs.
• A posteriori - draw inferences from our experiences.
o Romans 1:19-20 - ‘since what may be known about God is plain to them, because God has made it plain to them. For since the creation of the world God’s invisible qualities - his eternal power and divine nature - have been clearly seen, being understood from what has been made, so that people are without excuse’.
pattern of design argument/teleological argument
- Whenever we see things made by people, which are ordered in a pattern, or beautiful, or particularly complex, which work well to achieve a goal, we can infer that an intelligent designer must have designed them that way.
- Order, beauty (Augustine), complexity and/or purpose do not arise by blind chance.
- We can see order, beauty, complexity and/or purpose in the natural world, and that things work well together to perform a function, the resemblance to human inventions is close.
- Therefore an intelligent being must have created the natural world like with machines.
- God is that intelligent being, and therefore God exists.
different versions of design/teleological argument
• Different versions of the argument stress different aspects of the design in the world:
o Regularity in the universe (Cicero)
o Movements of the planets and the seasons
o Evidence of purpose in the world (Aristotle - link to Natural Theology)
o Beauty in the natural world
aquinas design/teleolgical argument - context
o Aristotle’s works recently discovered by Europeans, come to light due to Christianity’s contact with Islam - immensely impressive due to its range and common-sense appeal to logic.
o Aquinas wanted faith and reason to work alongside each other (Natural Theology).
o Believed God could be reached through:
• Revealed Theology e.g. through the Bible
• Natural Theology, using our reason to reach valuable truths.
aquinas design/teleological argument - 5th way
- Aquinas notes that nature seems to have order and purpose to it.
- Nothing inanimate is purposeful without the aid of a guiding hand, no non-living thing can have its own purpose, metaphor of archer and arrow
- Therefore, when we look at the world around us and the purposiveness of inanimate objects, we can conclude the guiding hand of God must be behind it, meaning everything in nature which is moving without intelligence must be directed to its goal by God.
• ‘Everything operates as to a design. This design in from God.’ (Linking both purpose and regularity, nature is ordered to fulfil a purpose).
teleological argument: analogy of archer and arrow
- An arrow hits a target even though it doesn’t have a mind of its own.
- The archer, who has a mind of its own, shot the arrow.
- Things in the natural world follow natural laws.
- God caused the natural world to behave this way, just like the archer caused the arrow to behave in that way.
• This is an example of regularity of succession, the idea that everything in nature follows certain laws that lead to certain results.
positives of aquinas design/teleological argument
o Socrates would support: ‘With such signs of forethoughts in the design of living creatures, can you doubt that they are the work of choice or design?’
o Written in Christian book, tailored towards those who already believe.
paley design argument/teleological - context
o 17th-18th century: Great strides in the fields of science, used scientific discoveries to prove existence of God, as these rules appeared to work uniformly in all kinds of circumstances, revealing an order in the way inanimate objects operated.
o Paley = Archbishop of Carlisle.
paley design argument/teleological - design qua purpose
• 1st part of argument: design qua purpose
o Used analogy of a heath:
1. Walking on a heath, find a watch on floor.
2. Person notices how well the watch is ordered in order to tell the time, and would conclude that someone had made the watch, rather than it just happening by chance (complex, intricate, all cogs are perfectly intertwined).
3. All parts are assembled purposefully, if any of the parts were shaped differently, then they wouldn’t work.
4. Compare watch to nature
a. Human eye = extraordinary flexibility and ability to achieve purpose of sight
b. Wings of birds = engineered for flight
c. ‘Every manifestation of design, which existed in the watch, exists in the works of nature’.
5. Could compare watch and eye to world, most intricate design of all, too intricate to have developed by chance, must have been ordered by divine intelligence.
6. The whole of nature needs the grandest of all designers = GOD.
7. ‘The contrivances of nature surpass the contrivances of art, in the complexity, subtlety, and curiosity of the mechanism’ ¬- Natural Theology, 1802.
positives of paley design qua purpose
- Can link with idea of evolution - anthropic principle that these constants seem fine-tuned specifically to allow intelligent life to evolve.
- Socrates argued that the adaptation of human parts to one another, such as eyelids protecting the eyeballs could not have been due to chance and was a sign of wise planning in the universe.
- Aristotle strong believer in telos.
- 4 Causes: formal cause (design) and final cause (purpose).
paley design argument - design qua regularity
• 2nd part of argument: design qua regularity
o There is regularity and order in the universe - objects follow natural laws.
• Looked at:
• Astronomy e.g. planets
• Newton’s laws of motion e.g. acceleration
• Gravity
• = Design in universe
o The reason objects perform their job efficiently is because they were designed that way, could not be chance.
o Everything that is designed must have a designer; therefore due to the evidence of regularity in the universe, the universe must have a designer.
o ‘The universe is far more complex than a watch and so if a watch needs a watchmaker, the universe needs a universe maker, and that could only be God…’
positives of paley design qua regularity
- Cicero uses astrology, would have supported: ‘What could be more clear or obvious when we look up to the sky and contemplate the heavens, than that there is some divinity or superior intelligence?’
- Swinburne - there is beauty in the regularity of the universe, which we can observe. Given the regularity and the beauty, it is simpler to accept that there is a designer God, rather than assume this all happened by chance.
criticisms of teleological argument - hume
• David Hume (never directly criticised Paley, as was written 24 years before Paley’s book, Paley tried to respond to the critics of the teleological argument)
o Just because humans perceive design in the world, doesn’t mean there is design.
o We’ve got nothing to compare this universe to; can’t say what a non-designed universe would like. ‘You must acknowledge, that it is impossible for us to tell, from our limited views, whether this system contains any great faults, or deserves any considerable praise, if compared to other possible or even real systems’.
o The analogy between the ‘designed thing - world’ and ‘human designer - God’ is not a good one, ‘whenever you depart from the similarity of cases, you diminish proportionally the evidence; and may at last bring it to a very weak analogy’.
o Can only observe effect of creation of world, not cause. Uses analogy of a ‘body raised in a scale’.
o There’s no unity of the deity suggested in the design argument. ‘Why may not several Deities combine in contriving and framing a world?’
o There’s no reason if there is a designer, that it is a Christian God.
criticisms of teleological argument - mill
o If the world is designed by God, it does not indicate a loving God - ‘the order of nature, in so far as unmodified by man, is such as no being, whose attributes are justice and benevolence’.
o Seems simpler that it leads to no God than a bad God (link to Ockham’s razor - simplest explanation).
criticisms of teleological argument - dawkins
o ‘Natural selection has no purpose in mind. If it can be said to play the role of a watchmaker, it is the blind watchmaker…’
o Attempt to teach Intelligent Design is an ‘under-hand attempt to undermine secular education’.
o ‘Design can never be an ultimate explanation for anything. It can only be a proximate explanation. A plane or a car is explained by a designer but that’s because the design himself, the engineer, is explained by natural selection’.
o Dawkins is strong supporter of God of Gaps - can’t find explanation so simply place God in the missing evidence.
