This is someone whose cause of death is unknown because, as far as we know at this point, the revelation of his death is new, not because it's a scientific field of inquiry and experiment.
I disagree politely. Even the death of a beloved person is not above the scientific method. One may choose not to investigate, but that is a personal decision. I don't see a problem if someone far away speculates. Also, I don't see a problem talking about these speculation. As long as speculations stay speculations in the absence of evidence and are discarded in front of conflicting evidence, it seems sound to me.
That is an arrogant and aggressive appeal to emotion. But even following that non-logic, as soon as someone dies we are supposed to turn our head off and to shut up? I think quite the contrary, we should think even harder why it happened, and learn from that. After all, it is a significant event, and, in this case, a loss for all of us.
Ironically, your comment was putting fuel into the fire of speculation because here we weren't even conversing about the details and circmustances of the death. Now, a debate about the danger of alcohol, and, more interesting, the causes of alcoholism would be helpful. Alcoholism often has a cause, in my experience. Is that really so? Are these causes identifiable and fixable? That are questions that I wish we knew more about.
