the blind watchmaker
line of argument in aquinas’ 5th way
- observed from order in the universe
- natural bodies lack knowledge
- yet natural bodies act for an end/goal
- to obtain the best result would be to fully actualise your telos
=things that dont have knowledge must be guided by something that HAS knowledge eg a seed is not conscious but grows towards its telos.
aquinas’ 5th way is what type of argument
teleological, a posteriori
example given in aquinas’ 5th way
eg the arrow in mid flight is directed by the archer and has a target = the unintelligent must be directed by a knowledgeable entity.
paley’s design qua purpose argument summary
analogy of the watchmaker
the complexities of the world suggest that it was created perfectly by an intelligent mind: God.
paley’s design qua regularity argument
evidence from astronomy and newton’s laws that the rotations of the planets obeyed universal laws. things like gravity cannot come about by chance. everything exists in an order and harmony, any different and it would not function - an external agent must have imposed this: God.
paley’s watchmaker analogy
if you were walking and saw a stone on the floor - you would dismiss it and it would not be absurd to say it had lain there forever. if you came across a watch on the floor you would infer that all the parts fitted together for a purpose and has not come into existence by chance. its complex mechanisms and design infers there is an intelligent creator. in the same way we can look at the world and infer there is a creator. eg the eye is incredibly complex to be able to produce sight - the eye was designed for the purpose of sight and that this complex design implies there is an intelligent creator.

hume criticism 1 - questions over the nature of the designer
- since evil exists, what does this say about the creator? since they are responsible for the suffering and inequality in the world.
-the world is far from a perfect design, hume jokes the universe ‘is only the first rude essay of some infant deity’ , not a perfect designer
hume critique 2 - the use of the analogy
-there is no reason to assume this is the work of a monotheistic God, there is jsut as much evidence that there were many Gods involved in creation (none)
-using an analogy of a man-made machine makes the analogy guilty of ‘smuggling the conclusion into the premises’. we already know machines have creators so it is easier to arrive at the answer Paley is arguing
hume critique 3 - the epicurean hypothesis
question of whether a stable universe could randomly arise. in infinite time a huge number of particles freely move around, if one combination happened to represent a stable order, then it must occur. =>hume predicts evolution
hume critique 4 - cause and effect
-we cannot go form an effect to a cause greater than needed to produce the cause. gives example of set of scales where one pan is up - we have no idea how much heavier the other pan is or what each contains.
you cant find the cause of an effect by jsut using a greater cause, this cannot be proved
-Empiricists know knowledge of cause and effect is due to experience - a watchmaker has built a watch as we have seen watches being assembled. we cannot make the ‘necessary connexion’ betwee God and the creation of the universe
