Against the Stream: Chesterton, Mill and the Case for Thinking for Yourself

In 1925, G.K. Chesterton published The Everlasting Man, a big, cheerful, argumentative book about the whole history of the human race. Somewhere in it he dropped a sentence that people have been quoting ever since: a dead thing can go with the stream, but only a living thing can go against it.

It is worth a minute beside any river to see why it lands. A dead leaf never has to decide anything. It is carried, it arrives wherever the water arrives, and from a distance it looks exactly like a leaf that chose its course. The fish pushing upstream is doing something the leaf cannot do, and it is paying for it in every muscle.

Most of us spend most of our days as leaves. That is not an insult; it is how a mind works. We pick up opinions the way we pick up accents, from whoever is around us, and we do it so smoothly that we mistake the result for conviction. Nobody sits down and decides what they think about a hundred different things. The current decides, we agree with it, and the agreement feels like thinking.

That is the case for thinking for yourself, and Chesterton is only half of it. The other half comes from a man who would have argued with him about almost everything.

A warning first, because the slogan has a cheap version. Going against the stream is not a virtue in itself. A rock in the rapids does not go with the stream either; it just sits there while the water goes around it. And there is a kind of contrarian who swims the other way purely so the bank can watch him swimming. That is still the current deciding, only in reverse. The direction is picked by what everybody else is doing.

Chesterton's fish is not contrary. It has somewhere to go. The point of the sentence is not the direction of the swimming but the fact that something living is steering at all.

So the real question is not "am I against the crowd?" It is "who is steering?" Which brings us to Mill.

John Stuart Mill published On Liberty in 1859, and in its second chapter he made an argument that sounds modest and is actually brutal. He who knows only his own side of the case, he wrote, knows little even of that. If you have only ever heard your own position, you do not really understand it. You have never watched it get hit, so you do not know where it is strong and where it only looks strong.

Mill went further. A belief that is never challenged does not stay a belief; it hardens into what he called dead dogma, not a living truth. You can hold something true in a dead way. You can repeat it, defend it by reflex, and have no idea why it is true. Mill thought that was a real loss even for people who happened to be right.

Notice the vocabulary. Chesterton says dead things drift and living things swim. Mill says a belief can be dead or living. They disagreed about God, about the Church and about much of the shape of a good life, and still they reached for the same word. A conviction is alive when somebody is steering it, and steering takes work.

Here is the practical test that follows. Can you state the case against your own view so well that the people who hold it would say, yes, that is exactly what we think? If you cannot, you are not yet in a position to reject it. You are only in a position to wave at it from the bank.

There is nothing soft about this. Mill's test is harder than shouting. It asks you to do the one thing a crowd cannot do for you: spend an honest hour inside the opposite argument. Sometimes you come out where you went in, with firmer reasons. Sometimes you come out somewhere else. Either way, you have swum.

There is a second warning, and this one is Chesterton's own. Thinking for yourself does not mean thinking alone. In Orthodoxy he described tradition as the democracy of the dead: a vote given to the most obscure of all classes, our ancestors. His point was that the fashions of the present are also a stream, the loudest and most crowded one, and that the people who faced these same questions before us, without a feed, deserve a hearing before we decide the matter was settled last Tuesday.

That surprises anyone who assumes going against the stream means going against everything old. Often the stream of today is running away from the oldest wisdom there is, and the living thing swims upstream toward it. The test is not whether a view is old or new, popular or lonely. The test is whether you have looked at it with your own eyes.

This is why the best intellectual company is mixed. Orwell wrote that if liberty means anything at all, it means the right to tell people what they do not want to hear. Voltaire, in a letter, called doubt an unpleasant condition but certainty an absurd one. Lord Acton, who had thought hard about unchecked power, wrote that it tends to corrupt. Different centuries, different politics, one shared habit: each of them kept a door open to the other side.

Three questions are worth carrying into the week. What stream am I floating in right now, and who put me there? Can I state the best case against my own view, in words its holders would accept? And what would it take to change my mind? If the honest answer to the last one is nothing, the belief may be less alive than it feels.
