My philosophy textbook was asking to make a reconstruction of his argument to avoid his logical error where he basically says that there is 1 being that makes sure that natural things do their functions. I made the reconstruction allowing for the possibility of there being more than 1 designer.
I said: Unintelligent things always act in the same to get the best result.
If a thing always acts in a way to achieve the best result, then that thing does a function.
Therefore unintelligent things do a function.
If a thing does a function, it does so through design.
Therefore unintelligent do their functions through design.
If an unintelligent thing does a function by design, then there is at least one or more intelligent beings that make sure that it performs this function.
There exists at least one or more intelligent beings that ensures that natural objects do their functions.
Do you think this reconstruction is correct?
