SEVEN Australians will die today as a result of suicide, the leading cause of death in young Australian men. So the media interest surrounding one in particular, that of 45-year-old Nigel Brayley’s suicide, needs some explanation.

The sensational midnight meeting that led to the suspension of euthanasia campaigner Dr Philip Nitschke’s medical registration for his role in that suicide was certainly newsworthy, though Nitschke’s activities do not wholly depend on his licence to practise medicine.

Most likely interest is driven by the linked ideas of a “right to die” and “rational suicide”, terms that have been used repeatedly by Nitschke in explaining his support for Brayley’s actions. Neither idea is new (both stem from libertarian ideas of individual autonomy), nor is the drug Nembutal, which Brayley used, a new or unique means to achieve death through suicide.

But there’s a back-story here that’s essential to making sense of the theatre.

The ‘‘right to die’’ is not listed in the Universal Declaration of Human Rights. Article 5, which prohibits torture and inhuman treatment, certainly implies a right to relief of suffering at end of life, and it finds legal support in many jurisdictions (including Victoria).

But the language of rights is in any case bewildering, as it imposes an obligation on others (your right to die becomes my obligation to kill) and invariably engages with opposing rights. Consider the role of a doctor in a botched suicide attempt, for instance.

While it has served as useful shorthand for supporters of the evolving idea of providing exceptions to the Crimes Act in certain cases of deliberate killing by commission or omission, the “right to die” is ethics reduced to a bumper sticker and does little to further our understanding.

And as a statement of the bleeding obvious – we all are born with a right to die that cannot be infringed. Only the suffering associated with dying can be changed.

Rational suicide, on the other hand, has been with us for millennia. Acceptance that there are some circumstances where you should kill yourself or knowingly allow yourself to be killed is widespread in most cultures, including Western Christian ones.

Arguments against rational suicide based on a revealed truth that our bodies and lives do not belong to us do not convince philosophers or the broad public that suicide could never be a rational choice. And a scientific assumption that all suicide is due to mental illness is unproven and unprovable.

So rational suicide exists, but does that make it right? Suicide may be rational (it may have clear and understandable reasons) but Nitschke’s conclusion, that we should accept it and educate people on how to carry it out painlessly, is deeply flawed.

For all the millennia that rational suicide has found supporters, it has encountered systematic opposition based on the idea of public interest.

This “public interest” led to the criminalisation of rational suicide in England in the 13th century (you had to be considered sane to be prosecuted; one in eight were).

Punishment was also meted out to surviving family members, who were stripped by the Crown of all their belongings.

In his 1825 Commentaries on the Laws of England, Sir William Blackstone called suicide: a crime against God and nature, as well as a crime of depriving the King of a subject.

Though suicide was decriminalised in England in 1950 (and 17 years later in Australia), we still use the word “commit” with suicide, a term otherwise reserved for murder and sin.

Nowadays, the law prohibits suicide in more specific settings, guided by a US case that suggested, among other things, that “protection of the interests of innocent third parties” and “maintaining the integrity of the medical profession” could weigh against self-determination.

Philosophers vigorously disagree, but most continue to see contemporary reasons to question rational suicide, some arguing that the idea is nonsensical, while others argue that intervention to prevent suicide is warranted in any case, as an assessment of rationality is difficult to make.

The pragmatic findings that suicide commonly has an impulsive element, and that failed suicide may be associated with good quality survival, lend weight to the view that attempting to prevent suicide is a greater good than making it safer and more accessible.

The historical evidence that suicide rates vary with the philosophy of the times, with surges during the Age of Enlightenment and more recently with the Romantics, urges some caution in adopting an unqualified libertarian stance that privileges autonomy over all else.

At a time when extreme libertarian philosophers still find free will “unintelligible”, there are grounds for caution in embracing libertarianism as the principle upon which we judge acts of terminal self harm.

Rational suicide may exist, but is as sad as that driven by mental illness. It deserves our attention and our compassion, but not our complicity.
