problems with analogy

N – A problem with analogy argument is that we as human beings have no experience of world making.
E – We cannot reasonably claim that our world has been made because we have nothing of a similar making to compare it; we have not experience worlds being made. We can however do this with most objects because we can compare them to other manufactured objects. But e cannot use these objects to justify the creation and design of the earth.
I – From understanding and observing the growth of a hair, can we learn anything about the creation of man/woman?
L – Analogy isn’t coherent because, just because there is objects that have been designed (like a watch), they cannot justify the design of the world because we have no other experience of a designed universe.

N – It can also be argued that the arguments for analogy are weak.
E – The argument for analogy is that the world is designed just like a machine. Hume however argues that this is not a correct comparison because the world is far greater and more complex than a machine.
I – it is more sensible to compare the world to an animal or a plant, in the sense that a plant just grows and has not been designed. This example is still flawed though as to make comparisons they have to be alike in all relevant ways.
L – There are flaws with analogy because we cannot compare the complex world which we do not totally understand with something that isn’t a relevant comparison

Explains: Arguments from analogies are only reliable when the things being compared are similar.
Illustrate: Paley’s watch analogy is weak. Because a watch does not have many similarities to the universe. Hume argued that a better analogy would in fact be a vegetable because the earth is organic, like a vegetable and not mechanical like a watch. It would also be a better analogy because vegetables just grow and are not designed and we have no reason to suppose the universe is designed so this would be a better analogy. Hume said that the vegetable analogy was equally flawed but that we cannot infer on the basis of an analogy with a machine that the universe was designed.
Link: This is a problem because there are no good analogies to fit the universe so all arguments using analogies in this area will be weak.
