thanks for the list echo, 'masters of the mind' looks interesting, and I read a brief history of madness by Roy Porter, so I will look into 'madmen:..'
poppy, as to what my definition of madness is.., I'm not sure if I can answer that. Only that personally, I would much rather be described as mad then be termed mentally ill. I tend to think that madness is an external issue and not only involves the madman but the environment which possibly makes them 'mad' or termed mad. I tend to think 'Mental illness' is just a new word for an age old struggle. I suppose I have a bit of a spiritual/mythological bent on madness and believe that ancient ecstaticism and modern day psychosis may be one of the same only that societies reception to it has changed.
I'm not sure if I've given you my definition sorry, but more my line of inquiry I think...
