Hey all! I have a personal question, but hopefully this will be useful to more than just me. I'm going for a Ph.D in cognitive neuroscience. I am convinced this is what I want to do. Once I've achieved that, is it totally unrealistic to attempt another postgraduate degree in another field (say, mathematics / physics / biology / philosophy / linguistics)? Even if it is realistic, is it worth it? For example, I find linguistics (Kripke, Chomsky etc.) indispensable for understanding certain papers on the brain; ditto abstract algebra / quantum theory / philosophy of mind. However, I don't know if this means I actually want a degree in these fields, if a degree in these fields would means knowledge vs. no degree, or if having multiple degrees would improve my career prospects as a brainguy. In short, would I be better off with a Ph.D in my field and a ton of self-study in others, or multiple Ph.Ds (and less self-study)?
