It seems to me there is a striking similarity between Economics and Philosophy. It's hard to find the words, but I feel like the 'same parts' of my brain are being used when I am trying to solve a philosophical problem (generally) and when I think about a problem in economics (and this isn't the case in other Arts subjects). It could be because the problems in economics overlap with problems in philosophy but I feel there's more to this intuition (something methodological?) than that.
It is no surprise many prominent philosophers contributed greatly to the field of economics (JS Mill, Hume, A Smith, Marx, etc) and Philosophy/Economics majors score closely in standardized tests like the LSAT.
Is this an impression that is common amongst professional philosophers?
