Any argument from analogy is weak as it relies on experience
We have no experience of any other universe so we can't compare ours to anything
Can't compare human circulatory systems with the way sap circulates in a tree.
A machine is no comparison to a tree, this links to Paley's argument - but remember he wrote AFTER Hume
Unless there is a perfect similarity between the two objects you can not draw a conclusion about their design
Ship analogy: Many designs, trial and error
Ship anaolgy: Not just one person that builds the ship
No comarison between a house and the universe
If the house is faulty, what does that say about the designer?
PALEY rejected this: Not concerned with quality in the design
In this situation the tendancy is for things to go from disorder to order
Subsequently backed up by natural selection - order coming out of apparent randomness.
All living things are related
We have evolved over billions of years from a common ancestor
No evidence of design
DARWINISM not Darwin
Explains the emergence of complex living organisms without design or purpose
Survival of the fitest
Those that develop the skills to survive are the ones that do and manage to reproduce
