Just a few days apart, two debates recently took place in the House of Commons concerning life and death. In the first, MPs voted to decriminalise late-term abortions. In the second, they voted for assisted dying. Both times, the reach of death grew a little longer.

Imagine a mother about to have a baby who is suddenly having grave doubts about whether she can manage a new child as the moment draws near. It’s not hard to sympathise with many in this situation, but rather than recommend she goes through with the birth, and perhaps putting the baby up for adoption for childless parents desperate to adopt, we now have passed legislation that allows us to terminate the baby’s life instead. Proponents argued this was to relieve a small number of women who had been prosecuted for late-term abortions. The reality is, however, that it will probably become more common. In the debate, Jim Shannon MP pointed out that in New Zealand, in the first year after their parliament voted the same way, late-term abortions increased by 43 per cent.

A baby a week before and a week after birth are virtually identical. Yet as a result of this bill, it will not be a criminal act to end the life of the first, but it will be to do the same to the second. What’s the betting that the logic of this will stretch before long to allowing parents to terminate the lives of newborn babies with a new limit – say up to one month after birth? The arguments will be exactly the same – sympathy for distressed parents who suddenly realise they cannot cope with a new life on their hands, especially if the baby is discovered to be flawed in some way. When emotional sympathy, personal choice and the rights of the mother over the baby become the only moral arguments, the logic is inevitable.

Despite the argument shifting rapidly against the Terminally Ill Adults Bill – the vote passed by 314 votes to 219, with 32 MPs apparently having changed their minds - it now looks likely that this second bill will pass into law in a few years’ time, despite scrutiny in the Lords.

Here on Seen & Unseen, we have scrutinised the arguments put forward for assisted dying over past months. We have argued about the unintended consequences for the many of permitting assisted dying for the few. In The Times a while ago, I argued that if ‘dignity’ means autonomy — my ability to choose the place, the time and the manner in which I die — there is no logical reason why we should refuse that right to someone who, for whatever reason feels their life is no longer worth living, however trivial we may feel their problems to be. With this understanding of dignity as unlimited choice, the slippery slope is not just likely, it is philosophically inevitable.

In both cases the logic of the arguments used means the march of our ability to bring about death will not stop with these measures, despite their proponents’ assurances that safeguards are in place.

These two votes reminded me of something Pope John Paul II once wrote. In an encyclical, Evangelium Vitae – the Gospel of Life - he warned that “we are facing an enormous and dramatic clash between what he called a “culture of death” and a “culture of life”.

He warned that this “culture of death” would be “actively fostered by powerful cultural, economic and political currents which encourage an idea of society excessively concerned with efficiency.” It is, in effect, he argued, “a war of the powerful against the weak: a life which would require greater acceptance, love and care is considered useless, or held to be an intolerable burden, and is therefore rejected in one way or another. A person who, because of illness, handicap or, more simply, just by existing, compromises the well-being or lifestyle of those who are more favoured tends to be looked upon as an enemy to be resisted or eliminated. In this way a kind of ‘conspiracy against life’ is unleashed.”

They were strong words, and in the UK at least, back in 1995, might have seemed alarmist. Yet I couldn't help thinking of them as these two bills passed through the UK’s national parliament. In both cases, the bills were introduced very rapidly with little time for serious moral deliberation. Both depended on emotional appeals to a small number of admittedly distressing cases without serious consideration for the wider cultural and philosophical ramifications of these seismic moves. Both encouraged the steady encroachment of death on demand.

What concerns me is what these bills say about the kind of culture we are becoming. MND sufferer Michael Wenham makes the point powerfully that this is all about autonomy and independence, a spurious kind of compassion, and the fact that palliative care is more expensive than subtly encouraging the dying to take their own life. Looking behind the arguments for compassion, it's not hard to spot the iron law of libertarian ideas of freedom, where individuals have absolute rights over their own lives and bodies that trump everything else. This is the kind of libertarian freedom that prizes personal autonomy above everything else and therefore sees our neighbours not so much as gifts to be valued and cherished, but limitations, or even threats to our precious personal freedoms.

Pope John Paul was right. It does seem that we are opting for a culture of death. And my fear is that it won’t stop here.
