There is a lot that is vague about this article, maybe it is just a decision not to take sides on the matter?
But to get clear, at least on one point is easy: euthanasia is not suicide. And the author confuses the reasons for one with the reasons for the other.
Euthanasia, or the ‘good death’ is the voluntary decision of putting one’s life to an end because of an illness or unbearable life circumstance (old age, poverty, etc.). It is often quite reasonable and understandable, even if medical institutions tend to limit its application to that of a terminal physical illness.
But what is not spoken clearly about in public is the reason for suicide proper: how can someone without any physical ailment or negative living conditions, still commit suicide and claim to have reason for doing so! This is the real question of ‘rational suicide’. Of course, the moment such a question is asked, the temptation is to always respond by psychologizing suicide as ‘irrational’, then medicalizing it as an illness or a form of depression. But the habitual responses of illness and irrationality bypasses the problem … though it is a reflex of journalists who are forced to quote psychologists on the matter … it is what most have come to expect who borrow the language of the experts.
Are there, however, any reasons for a seemingly irrational suicide? Surely there are, but they are not those we have come to expect. But to detail these would take too much time for such a short response. Besides, I have done this elsewhere on this site.
