I don’t know about you, but I’m pretty nervous around horses. They’re very big, and they are (as far as I’m concerned) very unpredictable. I’ve heard horror stories of people who got kicked by horses, and I’m pretty much soured on them. But it occurred to me this evening that managing the caveman within each of us is very much like riding a horse. First you have to tame him, then you can take him wherever you please.

Think of our primal tendencies as the horse. When unsaddled and unbroken, the horse does pretty much what he wants, according to his natural proclivities – he seeks safety, food, and sex, and not necessarily in that order. And he’s big, which means he’s due a wide berth when he’s got a head of steam for something. Our goal as enlightened cavemen (and women) is to contain the horse, to control it. This is not unlike the process of breaking a wild mustang.

I have long believed that the human populations (in Africa or the Middle East, for example) that fare the worst in life are dominated by people who are driven exclusively by unbroken horses. Ancient emotions run wild – the quest for status, the indignation and enmity that come from reciprocal altruism unfulfilled, the in-group versus out-group mentality, the male urge to spread his seed far and wide, the willingness to believe falsehood if it supports any of the aforementioned, all of it. The horse lacks the benefit of a harness that is held by a rational, big-picture thinker. But, lest we miss a critical component of this concept, the thinker is not enough.

Were we jockeys without horses, we would be largely unfit for purpose. The thinker would be deprived of the chief instrument of his plans. Indeed, the thinker is never as good at finding shelter, food, and sex as the horse is. No, the horse is essential. He brings with him the courage, the strength, and the resolve to execute the visions of the thinker, even the most primitive of visions. So the first task is to harness the horse, to control him, and a daunting task it is.

The choice of the horse as the embodiment of the caveman mentality is not arbitrary. It is precisely the juxtaposition of power and unpredictability that make the horse the obvious choice. We cannot simply lasso him and expect him to submit. We have to convince him that he cannot win. Fortunately, the rich history of our species is replete with examples from which we can draw our confidence as horse breakers. So long as the horse believes that we are in control, he is ours to do with what we will. And still, it is not easy.

The unpredictability of our horse, even when broken, limits our options. If he gets spooked by dogs, we cannot expect his submission to override this. We must extend our thinking to include accounting for his quirks, for at least he is predictably unpredictable – he won’t spook for nothing, but when he does, there’s no telling what he’ll do. So the thinker gets to know his horse. He gets to know what spooks him and what soothes him so he can guide him gingerly around the obstacles that promote unpredictability. This is our task, and as with any worthwhile task, the rewards are manifest.

When we tame the horse, when we control the horse, we can ride him. We can find a delicate (but durable) balance between our big-picture designs and his power to achieve them. We can steer him around interpersonal conflicts that back him into a corner, but, when options evaporate, a few heels to the hindquarters are all it takes to spur him into action. This is what I’m after. This is what we should all be after – a tame horse that can be unleashed at will. Luckily, this is all figurative. No matter how much I may like this analogy, don’t look for me on a horse any time soon.
