Matters of religion should never be matters of controversy. We neither argue with a lover about his taste, nor condemn him, if we are just, for knowing so human a passion.
This quote sums up the apparent futility of argument—not only about religion, but about so many things that arouse strong feeling. I have never seen, or even heard of, a discussion about religion or politics that ended with one of the participants being convinced. If anything, conversations about these topics seem only to entrench the opposing parties in their positions.
This occurrence appears common and universal; and yet its implications strike at one of the pillars of western thought—that rational arguments can be used to reach the truth and to convince others—as well as of liberal democracy, which rests on the ideal that, to paraphrase John Milton, truth emerges victorious from open encounters with untruth. If debate is really futile in matters religious (which involves our ultimate views of life and the universe) and politics (which involves our stance on society), then are we doomed to endless tribal bickering based on nothing more than group mentality?
I strongly wish that this wasn’t the case; but I admit that, judging on my actions in daily life, I have little faith in the power of reason in these matters. I tend to avoid topics like religion and politics, even among friends. Powerful emotions underpin these aspects of life; values and identity are implicated; and individual psychology—background, traumas, inadequacies—may render the action far removed from cold calculation.
To a large extent, admittedly, rationality has only a subsidiary role in decision-making. Hume was quite right, I believe, to call reason a “slave of the passions.” We are never motivated by reason alone; indeed I don’t even know what that would look like. We are motivated, instead, by desires, which are organic facts. In themselves, desires are neither rational nor irrational. Rationality only applies, first, when we are figuring our how to satisfy these desires; and, second, when multiple, conflicting desires are at play.
The desires to be skinny and to eat three pints of ice cream a day, for example, conflict with one another, and reasoning is needed to achieve a harmony between these two. A reasoner may realize that, however, delicious ice cream may be, the desire to be skinny is consonant with the strong desire to be healthy and live long, so the ice cream is reduced. Both internally, within our psyches, and externally, within society, reason is how we achieve the most satisfying balance of competing desires.
Since reason rests on a fundamentally non-rational bases—namely, desires—it may be the case that reason has no appeal. In politics, for example, somebody may crave equality, and another person freedom; and no argument could move or undermine these desires, since neither is rational in the first place. Different political orientations are rooted in different value systems; and values are nothing but orientations of desires.
But I think it is often the case that competing value systems have many points in common. Grave inequality can, for instance, curtail freedom; and enforced inequality can do the same. For either party, then, a satisfactory society cannot have absolute inequality, absolute equality, absolute freedom, or absolute slavery. These different values are therefore not totally at odds, but are merely different emphases of the same basic desires, different ways to harmonize competing pulls. And in cases like these, rational argument can help to achieve a compromise.
What about religion? Here the case seems somewhat different from politics, since religion is not just a question of values but involves a view of reality.
Admittedly, political ideologies also involve a certain view of reality. Each ideology comes with its own historical narrative. Sometimes these narratives are nothing but a tissue of lies, as with the Nazis; and even the most respectable political narrative may make some dubious assumptions. Nevertheless, the validity of political opinions is not purely a matter of the truth of their historical narrative. Somebody may genuinely desire communism even if everything they assert about the Soviet Union is wrong; and if debunking their history makes us doubtful of the possibility of satisfying their desire, it does not invalidate the desire itself.
With religion, to repeat, the case is somewhat different, since religions assert some set of facts about the universe; and without this set of facts, the religion falls to pieces. All of Marx’s theories of history may be wrong, but you can still rationally want a communist society. But a Christianity without a belief in a divine Jesus has lost its core. It is no longer a religion. In this way religion is decidedly not like falling in love, contrary to Santayana, since love, being pure desire, makes no assertion about the world.
This seems to put religions on a different footing, since they rest not only on desires, but beliefs. And if these beliefs prove incorrect or irrational, then the religion ceases to make sense. From my readings in history, science, philosophy, and theology, it seems quite clear to me that this is the case: that insofar as religious notions can be disproved, they have been; and insofar as they are unprovable, they are irrational to believe.
Indeed, I think with enough time I could explain this quite clearly to a believer. But I have never tried, since I am almost positive it wouldn’t work—that their religious beliefs would be impervious to argument. I also admit that the thought of doing so, of trying to talk someone out of a religion, makes me feel uneasy. It seems impolite and invasive to try to exert so much pressure on somebody’s fundamental beliefs. And even if I were successful, I believe I would feel somewhat guilty, like I had just told a child that Santa wasn’t real.
But is this uneasiness justified? If religions are truly irrational, based on a mistaken picture of the world, then they can give rise to unjustifiable actions. The religiously inspired fight against gay marriage, climate change, and abortion are excellent examples of this. Furthermore, if people habitually accept an irrational picture of the world, basing beliefs on religious authority rather than reasoned arguments, then perhaps they will be more easily manipulated by unscrupulous leaders.
On the other hand, living in a liberal society requires tolerance of others’ beliefs, rational or otherwise. And living in a polite society requires that we respect even when we do not agree. So it seems that a balance must be struck between arguing against an irrational belief and keeping considerate silence.
