Understanding others—metaphor and its use in medicine
Peter Dorward
Metaphor is a powerful tool towards better understanding and healing.
‘It’s a debt that just gets bigger. Like a bad loan from the happiness bank.’
Today, Margot is talking about cocaine. But we’ve had this conversation before. Heroin, alcohol, Valium—there are a lot of street drugs around where I work. There are a lot of people looking for a fix.
Margot is thin, wide-eyed, shaky, tired, withdrawing. Her eyes plead.
‘I start off just to get a wee bump, but then later I’m feeling even worse, needing more, and then I’m just chasing my tail. And there’re always folk happy to give you a wee chucky bag when you’re rattling!’
A ‘chucky bag’ is a loan: of heroin, or cocaine or anything really. It’s a common business model. Drug dealers need to keep their clients happy, just like other business owners.
But I liked this line of hers—the bad loan metaphor. Later, I try it out myself, on another patient.
Big Tam needs something for his ‘anger management’. Big Tam has issues with alcohol, gambling, cocaine, violence, his past, his future and his personality. He’s trembling with rage. He’s barely holding it together as he stares hard at me through little pinhole eyes. He wants me to prescribe him more of the Valium a junior doctor in the emergency room gave him the other night, to ‘calm him down’.
’I won’t prescribe that for you,’ I tell Tam. I just won’t.
’Why the F not!?’ Tam can be pretty intimidating.
’Because valium will make everything worse,’ I remark.
Tam’s getting angry, ‘Raging Bull’ angry. I have an emergency response button somewhere. Under my desk, I think.
‘If I prescribe this for you, it will work for about a week. Then you won’t be able to manage without it. You’ll need more. Then stopping will be out of the question. The longer you take it, the worse it gets. It’s like…’
Pause. Think.
‘It’s like a debt. A high interest loan. From the happiness bank.’
Tam pauses. Tam has been in debt most of his adult life. Gambling, drugs, rent. How could he be otherwise? He’s been in and out of prison. Tam knows how men, left wild, use debt to coerce and control. He’ll have done it himself to others, no doubt. But to my absolute surprise, Tam nods a little.
‘So, what can you do for me, Doc?’
It’s not words nor their attendant facts that make us human. After all, animals communicate. Even computers have a language. Instead, it’s our ability to think in terms of unrelated things that makes us special: the power to imagine ourselves, potentially, as other than we are.
Margot compares her cocaine habit—the tenor of her metaphor—to a debt. Debt is the metaphor’s vehicle. Our shared world of mutual understanding—that which connects tenor to vehicle—is the metaphor’s ground. In this case, the false friend who traps you in crippling, worsening, dependency (figure 4).
Figure 4The structure of metaphor.
A good metaphor is flexible, arresting, immediately and effortlessly understood. It is creative, a little unpredictable. It is pregnant with meaning, and the meaning is undefined. And metaphor entails risk: we can’t always know what powerful change it might produce.
