On liberty’s limits: why Mill was wrong about freedom

This month, it’s 150 years since philosopher JS Mill died. His definition of freedom remains hugely influential. But is it still the right one for healthy relationships and contentment amid the isolation of modern life?

You can tell what a society values by what it goes to war over. In the 17th century we fought our wars over religion. In the 19th it was empire. In the 20th and 21st, we fought our wars over freedom, either defending our own or trying to export our version of it to other parts of the world. We tend, of course, to assume we know what freedom is: the liberty to do what we like, as long as don’t harm other people. But we rarely know how time-conditioned and recent such a view of freedom is.  

John Stuart Mill, child prodigy, colonial administrator, Member of Parliament and philosopher, who died 150 years ago this year, is one of the primary architects of our contemporary ideas of freedom. In his own words, his book On Liberty, published in 1859, was an exploration of the ‘nature and limits of the power that can legitimately be exercised by society over the individual’. Mill famously argues that the only valid reason for interfering with another person’s liberty of action is to protect them from physical harm. It is never justifiable to interfere with another person’s freedom to ensure their happiness, wisdom or well-being, because that is to determine what that person’s well-being is. Freedom is defined as liberty of conscience, thought, feeling and opinion, as ‘liberty of tastes and pursuits … doing as we like … without impediment from our fellow creatures, so long as what we do does not harm them’. 

For Mill... individual liberty is vital, not just for the sake of the individual, but for the sake of human progress.

Mill is one of the great champions of nonconformity in thought and action. Even if just one person held a particular opinion while everyone else in the world held the opposite, there would be no justification in silencing that one voice. For Mill, one of the main ingredients of social progress is freedom from the traditions and customs imposed by others, both the past constraints of tradition, and the present ones of custom, which restrict the cultivation of individuality, which in turn ‘is one of the leading essentials of well-being’. Individual liberty is vital, not just for the sake of the individual, but for the sake of human progress. Without it there will be no originality or genius, no new discoveries or innovation. Civilisation cannot advance without individual freedom which encourages spontaneous expression, the development of new thoughts and ideas unconstrained by the patterns of the past.  

It is a powerful argument. On Liberty is full of the fear of Victorian conformity – the individualist’s reaction to a stifling society with a high degree of social control. It is very much a book of its time, assuming the cultural superiority of the modern age. It also breathes an elitism that looks down on the mediocrity of what it calls ‘average men’.  

But more than that, there is, I think, a deeper flaw in this way of thinking about freedom. If freedom is essentially my liberty to say or do what I like, as long as I don’t tread on the toes of my neighbour, then what does that do to my relationship with my neighbour? He or she becomes at best a limitation, or at worst a threat to my freedom. There may be all kinds of things I want to do – play music loud on a summer’s night, or drive my car at 100 mph on a quiet suburban road – but I can’t because I might disturb my neighbour’s peace or risk crashing into an oncoming bus. Or even worse, my neighbour might want to play her music too loud for me, or drive her car too fast in my direction, thus invading my personal space. This approach keeps the peace between us, but at the cost of making us see each other either as irritating limitations to our desires which of course define our self-chosen goals in life, or threats to our own precious autonomy. 

The German sociologist Hartmut Rosa argues that  

“the ethical imperative that guides modern subjects is not a particular or substantive definition of the good life, but the aspiration to acquire the resources necessary or helpful for leading one.”  

In other words, in the individualised world imagined by Mill, we are all left to dream our own dreams, choose our own ambitions, and are all caught up in the fight to get hold of the money, rights, friends, looks, health, and knowledge that will enable us to get to our self-chosen destination. It therefore makes us competitors with each other, not only seeing each other as rivals in this race for resources, but also as potential threats who might stand in the way of our freedom to pursue our dreams.  

There is however another, older view of freedom, rooted more in character and virtue than in individualised personal goals. This version, found in classical literature, sees liberty not as freedom from the limitations and social expectations that stop us following our self-chosen desires, but freedom from the passions. The Greeks viewed the soul as like a ship which should sail serenely towards the harbour of such virtues as prudence, courage and temperance. It was guided on this journey by paideia, or education in virtue, yet was at the same time buffeted by the winds of irrational and destructive impulses such as envy, anger or lust that threaten to blow it off course. For them, our passionate inner desires are not the sacrosanct moral guide to our true selves but are a distraction from the true path of virtue.  

True liberty is freedom from anything that would stop us becoming the person we were created to be.

This version was developed further by Christian thinkers such as St Paul, St Augustine and Thomas Aquinas. For them, true liberty is freedom from anything that would stop us becoming the person we were created to be: someone capable of love for what is not ourselves – for God and our neighbour. True liberty is freedom from internal urges such as the greed, laziness or pride that turn us in upon ourselves rather than outwards towards God and each other. It is also freedom from external forces such as the grinding poverty that dangles the temptation to steal in order to survive, or an economy that constantly tells us that if you don’t acquire as much stuff as your neighbour you are a failure. It is not so much freedom for ourselves, but freedom from ourselves: freedom from self-centred desires, or the crippling self-absorption that makes us think only of our own interests. It is freedom to create the kind of society where we are more concerned with our neighbours’ wellbeing than our own.  

In this view of freedom, my neighbour becomes not a limitation or a threat, but a gift – someone without whom I cannot become someone capable of the primary virtue of love. Putting it bluntly, if I am to become someone capable of other-centred love, I need someone to practice on.  

This Christian understanding of freedom offers a vision of society where you might begin to trust other people to look after your own needs, because they are looking out for yours. It is also a vision of freedom that delivers personal happiness better than the libertarian view. Becoming the kind of person who has learnt, as St Paul once put it, to ‘look not to your own interests, but to the interests of others’ is in fact a recipe for healthy relationships and contentment rather than the increasing isolation of much modern life.  

Mill may have had a point in the stifling conservatism of Victorian Britain, but in an age of increasing loneliness, isolation and anxiety, his view of freedom doesn’t help build good neighbourhoods, families or communities. We need a better version - one that brings us together, rather than drives us apart.

Ethics needs to catch-up with genetic innovation

Are we morally obliged to genetically edit?

It makes me feel very old when I realise that Louise Brown, the first baby to be born via in vitro fertilisation (IVF), will be 47 years old on July 25th this year. Since her birth in 1978, over 10 million IVF-conceived babies have been born worldwide, of whom about 400,000 have been in the UK. Over that period, success rates have increased such that in some clinics, about 50 per cent of IVF cycles lead to a live birth. At the same time, there have also been significant advances in genetics, genomics and stem cell biology all of which, in relation to human embryos, raise interesting and sometimes challenging ethical issues. 

I start with a question: what is the ‘moral status’ of the early human embryo? Whether the embryo arises by normal fertilisation after sexual intercourse or by IVF, there is a phase of a few days during which the embryo is undergoing the earliest stages of development but has not yet implanted into the wall of the uterus; the prospective mother is not yet pregnant. In UK law, based on the Human Fertilisation and Embryology Act (1990), these early embryos are not regarded as human persons but nevertheless should be treated with some respect. Nevertheless, there are some who oppose this view and believe that from the ‘moment of conception’ (there actually isn’t such a thing – fertilisation takes several hours) embryos should be treated as persons. In ‘conventional’ IVF this debate is especially relevant to the spare embryos that are generated during each IVF cycle and which are stored, deep-frozen, in increasing numbers for possible use in the future.  

A further dimension was added to this area of debate when it became possible to test IVF embryos for the presence of genetic mutations that cause disease. This process is called pre-implantation genetic diagnosis and enables prospective parents who are at known risk of passing on a deleterious mutation to avoid having a child who possesses that mutation. But what about the embryos that are rejected? They are usually discarded or destroyed but some are used in research. However, those who hold a very conservative view of the status of the early embryo will ask what right we have to discard/destroy an embryo because it has the ‘wrong genes’. And even for the many who hold a less conservative view, there are still several questions which remain, including ‘which genetic variants we should be allowed to select against?; should we allow positive selection for genes known to promote health in some way?’; should we allow selection for non-therapeutic reasons, for example, sporting prowess?’ These questions will not go away and there are already indications that non-therapeutic selection is being offered in a small number of countries. 

Genetic modification 

This leads us on to think about altering human genes. Initially, the issue was genetic modification (GM) which in general involves adding genes. GM techniques have been used very successfully in curing several conditions, including congenital severe immune deficiency and as part of treatment programmes for certain very difficult childhood cancers. One key feature of these examples is that the genetic change is not passed on to the next generation – it just involves the body of someone who has already been born. Thus, we call them somatic genetic changes (from the Greek, sōmatikos, meaning ‘of the body’).  

Genetic modification which is passed on to the next generation is called germline GM which means that the genetic change must get into the ‘germ cells’, i.e., the sperm or egg. Currently, the only feasible way of doing this is to carry out the genetic modification on the very early embryo. At present however, with just one very specific exception, GM of human embryos is forbidden in all the countries where it would be possible to do it. There is firstly the question of deciding whether it is right to change the genetic makeup of a future human being in such a way that the change is passed to succeeding generations. Secondly, there are concerns about the long-term safety of the procedure. Although it would involve adding specific genes with known effects, the complexity of genetic regulation and gene interactions during human development means that scientist are concerned about the risks of unforeseen effects. And thirdly, germline GM emphasises dramatically the possibility of using GM for enhancement rather than for medical reasons.  

Genome editing 

This leads us to think about genome editing. In 2011, it was shown that a bacterial system which edits the genomes of invading viruses could also work in other organisms This opened up a large array of applications in research, agriculture and medicine. However, the ethical issues raised by genome editing are, in essence, the same as raised by GM and so there is still a universal prohibition of using the technique with human embryos: germline genome editing is forbidden. Despite this, a Chinese medical scientist, He Jiankui, announced in 2018 that he had edited the genomes of several embryos, making them resistant to HIV; two babies with edited genomes had already been born while several more were on the way. The announcement caused outrage across the world, including in China itself. He Jiankui was removed from his job and then, after a trial, was imprisoned for three years; his two colleagues who collaborated in this work received shorter sentences. 

At present the universal prohibition of human germline genome editing remains in place. However, the discussion has been re-opened in a paper by an Anglo-Australian group.  They suggest that we need to develop heritable (i.e. germline) polygenic genome editing in order to reduce significantly an individual's risk of developing degenerative diseases. These includecoronary artery disease, Alzheimer’s disease, major depressive disorder, diabetes and schizophrenia. I note in passing that one of the authors is Julian Savulescu at Oxford who is already well-known for his view that parents who are able to do so, are ‘morally obliged’ to seek to have genetically enhanced children, whether by PGD, GM or genome editing. The use of polygenic editing, which would, in all likelihood, be available only to the (wealthy) few, fits in well with his overall ethical position. Needless to say, the paper, published in the prestigious journal Nature, attracted a lot of attention in the world of medical genetics. It was not however, universally welcomed – far from it. Another international group of medical scientists and ethicists has stated that ‘Human embryo editing against disease is unsafe and unproven …’ and even go as far as to suggest that the technology is ‘… going to be taken up by people who are pushing a eugenics agenda …’ remain very pertinent. 

Harder still and harder 

I have no doubt that amongst different reader there will be a range of opinions about the topics discussed so far. For anyone who is Christian (or indeed an adherent of almost any religious faith), one of the difficulties is that modern science, technology and medicine have thrown up ethical questions that could not have even been dreamed of by the writers of the Bible (or of other religious texts). We just have to use our wisdom, knowledge and general moral compass (and for some, prayer) to try to reach a decision. And if what I have already written makes that difficult, some recent developments multiply that difficulty still more.  

In the early years of this century, scientists developed methods of transforming a range of human cells into ‘pluripotent’ stem cells, i.e., cells capable of growing into a wide range of cell types. It also became possible to get both induced stem cells and natural stem cells to develop into functional differentiated cells corresponding to specific body tissues. This has huge potential for repairing damaged organs. However, other applications are potentially much more controversial. In 2023, Cambridge scientists reported that they had used stem cells to create synthetic mouse embryos which progressed at least as far as brain and heart formation within the normal pattern of mouse embryo development. 

At about the same time, the Cambridge group used individual human embryonic stem cells (from the blastocyst stage of embryonic development), to ‘grow’ early human embryos in the lab. There is no intention to use these embryos to start a pregnancy – indeed, it would be illegal to do so – but instead to study a period of embryo development which is not permitted with ‘real’ human embryos (research must not continue past 14 days of development). But how should we regard synthetic embryos? What is their moral status? For those who hold a conservative view of the normal human embryo (see earlier), should we regard these synthetic embryos as persons? Neither does the law help us. The legal frameworks covering in vitro fertilisation and early embryos (Human Fertilisation and Embryology Acts, 1990, 2008) do not cover artificial embryos – they were unknown at the times the legislation was drawn up. Indeed, synthetic embryos/embryo models are, in law, not actually embryos, however much they look like/behave like early embryos. Earlier this month, the Human Fertilisation and Embryology Authority (HFEA) discussed these developments with a view to recommending new legislation, but this will not dispel an unease felt by some people, including the science correspondent of The Daily Telegraph, who wrote that this research is irresponsible.  

But there is more. In addition to synthetic embryos, the HFEA also discussed, the possible use of gametes – eggs and sperm – grown from somatic stem cells (e.g., from skin) in the lab. Some authors have suggested that the production of gametes in vitro is the ‘Holy Grail’ of fertility research. I am not so sure about that but it is clear that a lot of effort is going into this research. Success so far is limited to the birth of several baby mice, ‘conceived’ via lab-grown eggs and normal sperm. Nevertheless, it is predicted that lab-grown human eggs and sperm will be available within a decade. Indeed, several clinicians have suggested that these ‘IVGs’ (in vitro gametes) seem destined to become “a routine part of clinical practice”.  

The lab-grown gametes would be used in otherwise normal IVF procedures, the only novelty being the ‘history’ of the eggs and/or sperm. Clinicians have suggested that this could help couples in which one or both were unable to produce the relevant gamete, but who still wanted to have children. In this application, the use of IVGs poses no new ethical questions although we may be concerned about the possibility of the gametes carrying new genetic mutations. However, some of the more wide-ranging scenarios do at the least make us to stop and think. For example, it would be possible for a same-sex couple to have a child with both of them being a genetic parent (obviously for males, this would also involve a surrogate mother). More extremely, a person could have a child of which he or she was actually, in strictly genetic terms, both the ‘father’ and the ‘mother’. What are we to make of this? Where are our limits?  

Dr Christopher Wild, former director of International Agency for Research on Cancer, explores in depth many of the developments and issue I outlined above. His article on why a theology of embryos is needed, is clear, well-written, helpful and thought-provoking.
