Is Health Care a Human Right?

How can libertarians be so heartless as to not believe in a right to health care? I will try to answer that question. While I might not convince you that there isn't a right to health care, I hope to at least convey that, whatever a "right" to health care is, it is something fundamentally different from the sort of thing we usually call a "right"-so different, in fact, that we probably shouldn't be using the same word.
