Intellectual Virtues

One of my favorite works in philosophy is a book by the English philosopher John Stuart Mill (1806-1873) titled On Liberty. Throughout this elegantly written essay Mill offers excellent advice on how to think clearly about the proper limits of state coercion and the freedom of the individual citizen.

In chapter two he takes up the related topic of a citizen's responsibility to inform him or herself on important matters like "morals, religion, politics, social relations, and the business of life". In these, Mill suggests, we should make it our practice to follow the example of one of the greatest rhetoricians in history, Marcus Tullius Cicero.

Mill writes:
The greatest orator, save one, of antiquity, has left it on record that he always studied his adversary’s case with as great, if not with still greater, intensity than even his own. What Cicero practised as the means of forensic success, requires to be imitated by all who study any subject in order to arrive at the truth.

He who knows only his own side of the case, knows little of that. His reasons may be good, and no one may have been able to refute them. But if he is equally unable to refute the reasons on the opposite side; if he does not so much as know what they are, he has no ground for preferring either opinion.

The rational position for him would be suspension of judgment, and unless he contents himself with that, he is either led by authority, or adopts, like the generality of the world, the side to which he feels most inclination.
How many people know, for example, the arguments on the other side of the issue from their own on matters like the existence of God, evolution, immigration, climate change, abortion, gay marriage, etc.? If we don't know what the opposing arguments are on such questions how are we justified in dogmatically declaring or believing that our opinion is the only one that it's reasonable to hold?

Mill continues:
Nor is it enough that he should hear the arguments of adversaries from his own teachers, presented as they state them, and accompanied by what they offer as refutations. That is not the way to do justice to the arguments, or bring them into real contact with his own mind.

He must be able to hear them from persons who actually believe them; who defend them in earnest, and do their very utmost for them.

He must know them in their most plausible and persuasive form; he must feel the whole force of the difficulty which the true view of the subject has to encounter and dispose of; else he will never really possess himself of the portion of truth which meets and removes that difficulty.
In other words, if we only hear opposing views from those who agree with our position then we're probably not hearing those views presented as cogently as they would be by someone who really believed them. We shouldn't be afraid to read books and listen to lectures by people with whom we disagree. It'll either sharpen our own views or lead us closer to the truth.

Those on college campuses today who seek to shout down speakers they disagree with, or to prevent them from even appearing on campus, are, in addition to revealing their own intellectual primitiveness, doing both the truth and their fellow students a grave disservice.

John Stuart Mill
Most people, even educated people, Mill laments, don't really know the arguments against the positions they hold:
Ninety-nine in a hundred of what are called educated men are in this condition; even of those who can argue fluently for their opinions. Their conclusion may be true, but it might be false for anything they know: they have never thrown themselves into the mental position of those who think differently from them, and considered what such persons may have to say; and consequently they do not, in any proper sense of the word, know the doctrine which they themselves profess.

They do not know those parts of it which explain and justify the remainder; the considerations which show that a fact which seemingly conflicts with another is reconcilable with it, or that, of two apparently strong reasons, one and not the other ought to be preferred.

All that part of the truth which turns the scale, and decides the judgment of a completely informed mind, they are strangers to; nor is it ever really known, but to those who have attended equally and impartially to both sides, and endeavoured to see the reasons of both in the strongest light.
Of course, few people have the time, let alone the inclination, to thoroughly explore all sides of all important issues, but if we don't then we certainly have no justification for being dogmatic in expressing our opinions. It would be better instead to display a genuinely open-minded intellectual humility which, so far from communicating the message, "I'm right and you're wrong", says instead that, "I might well not know all that I should about this matter, but here's what I think based on what I do know...."

Unfortunately, just as in Mill's time, open-mindedness and humility are two intellectual virtues not conspicuous among those participating in debates on the issues of our day.
