I’ve been reading through John Stuart Mill‘s On Liberty over the past couple of weeks. It’s a short work, less than a couple hundred pages, but dense enough to read slowly. For those unfamiliar with Mill, he’s seen as a “father of liberalism”. Liberalism has many branches now but I would say that what holds them together is an emphasis on the right of the individual to believe and live the “good life” as they see fit as long as it doesn’t violate “the harm principle,” meaning as long as it doesn’t hurt anyone else. Obviously, that’s easier said than done but I think most “western” societies have tried to abide by this principle.

Mill lived from 1806-1873 in Victorian England. While his ideas may be the water in which we swim now, or so argues the philosopher Alexander Lefebvre in his excellent Liberalism As a Way of Life (a book that I finished reading and need to say something about here soon), his ideas regarding individual freedom were radical for the time. This isn’t too difficult for me to understand if I consider the plight of LGBTQIA+ Americans in my own lifetime and slightly before. Harvey Milk was killed a mere four years before I was born. Even in “liberal” California where I was raised, I heard plenty of voices desiring to push queer people “back into the closet” because their “way of life” was something, in the view of many of the adults in my life, a private matter, at best. I heard many preachers refer to nearby San Francisco as “Sodom,” citing the common misconception that the city of Sodom from the biblical Book of Genesis was destroyed by the Bible’s God because of homosexuality. On the other hand, I’ve seen society because far more tolerant, at least, and accepting, at best, of our LGBTQIA+ friends (mostly the LG part; there’s a lot of work to be done after that still). And this “progress” as many of us would call it has little to do with the generosity and gracefulness of Christians. Instead, it has to do with the continued impact of people like Mill whose “live and let live” philosophy continues to influence us, even as forces of illiberalism threaten it, like, for example, the Christian Nationalist movement.
Rejecting Christian Nationalism
For Mill, ideologies like Christian Nationalism, which argue that the United States is a “nation by Christians for Christians to practice Christianity,” and that everything from our “moral” laws to immigration policies should reflect that, are in error. They’re in error for two reasons: (1) history and (2) epistemology. With regard to history, Mill argues that Christians, and others, have made mistake after mistake when they tried to use the power of the state to force others to live as they wished, and that this history should be a warning to us that we could do the same if we veer away from being liberal. With regard to epistemology, Mill points to the frailty of human knowledge, how we are limited to our own time and place and how those limitations keep us from the “god’s-eye view” that we assume when they forget that we’re not infallible by forcing everything from our metaphysics to our morality upon others, especially if their metaphysics and morality, when practiced, doesn’t impact us directly. Let me unpack this with some exegesis of On Liberty (from the edition published by Arcturus Press for page number references).
Answering the Questions for Ourselves
Mill begins by acknowledging that one may be convinced on the truthfulness of their understanding of Christianity. He doesn’t want to attack that when we warns us about the problem of our own fallibility, at least not directly. Instead, he begins with the principle that as convinced as we might be, we can’t force that conviction upon others. He writes, “…it is not the feeling of sure doctrine (be it what it may) which I call the assumption of infallibility. It is the undertaking to decide the question for others, without allowing them to hear what can be said on the contrary side.” (p. 36) For those Christians who care about our foundational sources in the New Testament, it is clear from the Gospels, the Book of Acts, the epistles of St. Paul, etc., that the earliest Christians felt the need to persuade people of their Gospel. They didn’t have the power of the Roman state to help them, so this was necessary, but also it says something about the very nature of Christian proclamation: ultimately, reception of the Gospel must be voluntary, even for those that inherit the faith from previous generations.
Killing Socrates and Jesus
As a warning, Mill reminds his audience of the great mistake of the Athenians who voted to execute the great father of western philosophy, Socrates, and how in retrospect that proved short-sighted and foolish. But not to stop there: if the death of Socrates was an injustice, “the event which took place on Calvary rather more than eighteen hundred years ago” (p. 37) should stop Christians in their tracks when they try to use the power of the state. It was the power of the Roman state that was used to wrongly execute Jesus himself! How then can Christians make the same mistake?!
Similarly, Christians should ponder the origins of their religion, and how the Romans mistreated (at best) and persecuted (at worst) Christians, only for Christianity to eventually emerge as the religion of the empire. If Christianity was true, and it was going to be true for your average Roman, what foolishness to persecute it! But persecute they did and persecute they continued to do, even after becoming Christian, just against Christians that were perceived as “unorthodox” or “heretical”. Seemingly, Christians didn’t learn from the early rejection and persecution the concept of tolerance. Once the oppressed was in power, they became the oppressor, and Mill wants to warn against the impulse to do this. As Mill writes “Orthodox Christians who are tempted to think that those who stoned to death the first martyrs must have been worse men than they themselves are, ought to remember that one of those persecutors was Saint Paul.” (p. 38) If St. Paul could be in error, so can you!
Now, the example of early Christian persecution may lead some to think that persecution is justified. In other words, they may conclude that persecute we must because if something is true, it will rise to the challenge, just like Christianity did. Mill rejects this (“the dictum that truth always triumphs over persecution, is one of those pleasant falsehoods which men repeat after one another till they pass into commonplace,” p. 41). If for no other reason, that such a mindset deprives a generation, or many generations, of the benefits of that truth. Mill observes, “The real advantage which truth has, consists in this, that when as opinion is true, it may be extinguished once, twice, or many times, but in the course of ages there will generally be found persons to rediscover it, until some one of it reappearances falls on a time when from favorable circumstances it escapes persecutions until it has made such head as to withstand all subsequent attempts to suppress it.” (p. 42) This is wonderful, but bad for the many generations who lost out on the truth that was buried by the arrogance of the times.
The Impotence of Intolerance
What does our intolerance accomplish? Not much. Mill uses the example of the atheist who is willing to face the public consequences of their atheism in Victorian England. Are they not the most honest hearted people? They must believe their atheism truly? What about the atheist who poses as a believer to avoid penalty? What does this create? Churches with atheists who don’t want to be there, i.e., Christians who are pretending! “Under pretense that atheists must be liars, it admits the testimony of all atheists who are willing to lie, and rejects only those who brave the obloquy of publicly confessing a detested creed rather than affirm a falsehood.” (p. 43) To do this is to cultivate vice among the people and suppress virtues like truth-telling, all in the name of preserving “Christianity” among the people.
What does our intolerance accomplish? It doesn’t remove the “heretics,” according to Mill. Instead, it suppresses the greater minds of a generation. If people’s very livelihoods are at risk, they won’t pursue the truth (p. 45). If they don’t pursue the truth, that generation loses out on their insights (p. 46):
“A state of things in which a large portion of the most active and inquiring intellects find it advisable to keep the genuine principles and grounds of their convictions within their own breasts, and attempt, in what they address to the public, to fit as much as they can of their own conclusions into the premises which they have internally renounced, cannot send forth the open, fearless characters, and logical, consistent intellects who once adorned the thinking world. The sort of men who can be looked for under it, are either mere conformers to commonplace, or time-servers for truth those arguments on all great subjects are meant for their hearers, and are not those which have convinced themselves”
The Universal, Ugly Side Effects of Intolerance
And it’s the fear of being wrong that hurts us all. Because an environment open to free thinking may create heretics, yes, but it will create much more good: “Truth gains more even by the errors of the one who, with due study and preparation, thinking for himself, than by the true opinions of those who only hold them because they do not suffer themselves to think.” (p. 47) When a society suppresses free thinking, it hinders creativity-within-orthodoxy, making orthodoxy dull and lifeless. Mill writes, “The greatest harm is done is to those who are not heretics, and whose mental development is cramped, and their reason cowed, by fear of heresy. Who can compute what the world loses in the multitude of promising intellects combined with timid characters, who dare not follow out any bold, vigorous, independent train of thought, lest it should land them in something which would admit of being considered irreligious or immoral?” (p. 47)
Steel Man
In Mills’ view, “orthodoxy” should be able to hold its own in the court of public opinion. Religious dogma proves itself weak when it must be forced upon others, as if suddenly people pretending to believe something out of fear makes it true! Mill argues, “Whatever people believe, they ought to be able to defend against at least the common objections.” (p. 49) (On a side note, I don’t think this is meant to encourage the “I did my own research” culture of the Internet. Remember, he qualified that research must be done by “one who, with due study and preparation” is “thinking for himself” with a strong emphasis on that “due study and preparation”. If I want to talk about climate, or astronomy, or geology, or vaccines, etc., “due study and preparation” may take years!) For Mill, one shows that they have a strong view not because they can articulate it, but when they can articulate it and its opposing view. When you can steel man your opponent’s argument, but still find it weak, then you know you have some solid ground upon which to make your stand. And you can’t debunk a view you don’t like by citing opponents of the view. One “must be able to hear them from person who actually believe them” (p. 51). Now, maybe the average person doesn’t have the time to do all this “research”. So be it. But those who shape public thought and policy must! “If not the public, at least the philosophers and theologians who are to resolve the difficulties, must make themselves familiar with those difficulties in their most puzzling form; and this cannot be accomplished unless they are freely stated, and placed in the most advantageous light which they admit of.” (p. 52)
Dead Beliefs
Mill notes that many “teachers of all creeds” often can be heard “lamenting the difficulty of keeping up in the mind of believers a lively apprehension of the truth which they nominally recognize” (p. 54). But he says, “No such difficulty is complained of while the creed is still fighting for its existence” (p. 54) In other words, if you want people to remain committed to a belief, you shouldn’t want it to be commonplace. You must want people to be confronted by it! Mill comments, “To what an extent doctrines intrinsically fitted to make the deepest impressions upon the mind may remain in it as dead beliefs, without being ever realized in the imagination, the feelings, or the understandings, is exemplified by the manner in which the majority of believers hold the doctrines of Christianity.” (p. 55) For Mill, the teachings of the New Testament “are considered sacred, and accepted as laws, by all professing Christians,” but they’re rarely practiced in actuality, because they’ve become so common place. People take comfort in merely affirming these doctrines, but they’re rarely confronted by them. How can this be? “The standard to which he does refer it, is the custom of his nation, his class, or his religious profession. He has thus, on the one hand, a collection of ethical maxims, which be believes to have been vouchsafed to him by infallible wisdom as rules for his government; and own the other, a set of every-day judgments and practices, which go a certain length with some of those maxims, not so great a length with others, stand in direct opposition to some, and are, on the whole, a compromise between the Christian creed and interests and suggestions of worldly life.” (p. 55) In short, Christians interpret something like say the “Sermon on the Mount” through the lens of their culture, denominational teachings, etc., seeing them as morals that they affirm because those morals have been interpreted for them and to them in such a way that they feel like they’re in the right.
Once this has happened, whatever power such teachings had to confront said Christians has been removed, and now this sense of “rightness” can be weaponized. “But in the sense that living belief which regulates conduct, they believe these doctrines just up to the point to which it is usual to act upon them. The doctrines in their integrity are serviceable to pelt adversaries with; and it is understood that they are to be put forward (when possible) as the reasons for whatever people do that they think laudable.” (p. 56) Anyone who has been around Christianity for any length of time knows this is true if they’re honest. And speaking personally, I know it to be true of myself. When I read the Sermon on the Mount without trying to justify myself, I often come away thinking “how can I live up to this?” Christ’s teachings will do that. One can weaponize Christ’s teachings only if they’ve found a way to interpret them so that they, suspiciously, always align with the morals and values of the reader! Mill knew this and tried to spotlight it for his readers.
Now, Mill thinks it’s actually a good thing if we’re a bit syncretistic. That may be a topic for another post. So, Mill isn’t trying to shame Christians for building their morality from multiple points of view. All he wants is for us to admit that this is what we’re doing, and he wants Christians who act as if they’re the ones who alone understand the New Testament and its teachings rightly to pause and be a little more introspective.
Mill’s Liberalism
When I say that Mill thinks Christians should be liberal, I don’t mean, necessarily, that they hold to a “liberal” theology, like say one that reinterprets the creeds, or that they embrace the individualism of libertarianism, or that they embrace the policies of neoliberalism, etc. I mean, specifically, that we take into consideration our own fallibility, especially around matters regarding religion, or philosophies of how we should live, and that we recognize from history how often the most confident were the most in error. This demands humility. It requires a little of “live and let live,” especially if we can’t show how someone else’s actions, beliefs, associations, mythologies, etc., hurt other people (and by “hurt” we mean actual harm, not just discomfort or a feeling of disagreeableness). Christians should take from their own scriptures the scenes where people crucified Christ wrongly, and how St. Paul boldly persecuted, and how the Roman Empire suppressed, as a reminder of how easy it can be to be confidently wrong. If Christians abide by the principles Mill sets forth, they won’t have microwaved answers on what politicians or policies to support in modern democratic life, for example, and at best they’ll have one driving principle for dogmatism: avoid harming others. If Christians took these ideas into consideration, I think we’d see a far healthier Christianity, at least in the part of the world where I live.
