At some level this makes sense – philosophers (can) specialise in the study of ethics and morality, and as a result of this training they will have a better idea of what is “right or wrong”, and why it is so, then other people. My impression of “rightness” and “wrongness” is that it is subjective – deciding what is wrong involves making moral judgments.
As a result, if we accept this, then when forming policy it is Philosophers that should be the ones forming the subjective value judgments required to qualify what the appropriate policy is.
The job of economists is to describe – we have to objectively describe what happens to a bunch of variables in society when one of them is moved. However, if Philosophers are the experts when in comes to value judgments – they should be the ones that place a values on different variables, so when the economists model moves it can come to some sort of conclusion.
What do you guys think? How do other disciplines fit into the policy creation process?
