arguments based on observation - teleological Flashcards
the teleological argument is the study of what
telos
what does telos mean
everything in the world is designed to reach a purpose
is this argument apriori or a posteriori
a posteriori because gains knowledge from design in the world to prove the existence of god
what is aposteriori
knowledge gained from experience
william paleys book
‘natural theology’
paley uses the analogy of
the watch
what is an analogy
a comparison of two similar things
paley uses an analogy in his argument to demonstrate
why it is reasonable to infer that there is a designer of the world and from this that there is therefore a god
paleys first argument - design qua purpose
if i found a stone in a field, i could assume it had been there forever
if i found a watch in a field, i would not make the same inference
this is because the watch and the stone differ in significant ways
the watch (purpose and complexity)
the watch has a purpose which is to tell time
the watch is complex as individual parts work together to fulfil its purpose
what happens if the watch does not work ?
it does not matter if the watch fails to work, the point is the watch’s existence suggests it was designed for a purpose. just because the watch doesn’t work, doesnt mean the watch does not show elements of design. there is a difference between having no purpose and failing to work properly to fulfil the purpose
conclusion of paleys first argument
- the fact that the watch has both purpose and complexity infers that it has design, and is not the product of chance. if it has design, it follows that it must have a designer, we can call this designer watchmaker.
- if any parts were shaped differently the watch would not work. all parts are assembled purposefully in this order, meaning there must be a designer. the designer is a watchmaker
watch quote
“every manifestation of design, which existed in the watch, exists in the works of nature”
paley states the same design in the watch is found in the natural world
evidence of purpose in the world
many systems that work to ensure life exists - eg water cycle, carbon cycle, food chains.
these also show complexity, as all systems work together
paley’s evidence of purpose and complexity using science at his time
scientific knowledge at his time, how muscles and tendons in the arm work or how the eye works
these both show purpose and complexity
purpose and complexity still exist in these things even if it goes wrong eg. (from examples)
earthquakes in the natural world
being blind - how eye works
breaking arm - muscles and tendons in arm
purpose and complexity still exist
paley is not saying the world is like a machine (the watch) he is saying…
the world has purpose and complexity, just like a watch does, so we can infer they each have a designer
the second part of paleys argument
design qua regularity
three things that show design in the universe
- astronomy (planets)
- newtons laws of motion
- gravity
this design shows regularity, routine and consistency so is known as ‘design qua regularity’. for example, the planets orbit the sun, they do not know themselves how to do this, nor that they need to do it
these are laws of nature, but nature is not able to create laws which organise the universe. therefore there must be an intelligence which is responsible for these laws. we can infer that there is a designer that created these called God.
thomas aquinas quote
“everything operates as to a design”
in ‘summa theologica’ aquinas has five ways to prove the existence of God. which is design qua regularity
the fifth way
what is aquinas fifth way
- the world shows evidence of purpose
- the world lacks the intelligence to direct this purpose
- so there must be an intelligence that directs this
Archer and arrow analogy - we call this intelligence God
analogy: archer and arrow
- an arrow hits a target even though it does not have a mind of its own
- the archer (someone with a mind of their own) shot the arrow
- things in the natural world follow natural laws
- god caused the natural world to behave in this way
the archer and the arrow is an example of ‘regularity of succession’
everything in nature follows certain laws that lead to certain results being achieved.
richard dawkins quote
“no purpose, no evil no good, nothing but blind indifference” from ‘the blind watchmaker’ - the world is so faulty that the watchmaker must be blind
