I’m a big-picture kind of guy. I like to know where things are headed, and why. Only then can I really focus on the particular parts or steps.
So, in looking at living a virtuous life, a fully human and humane life, my first question is, “What makes an action or a habit to be virtuous?”
As far as I can see, there are three contenders for the title of “form of the virtues,” or, to put it another way, “foundation of morality.” They are:
- Duty
- Interest
- Love
Now, before I go any further, I think it’s clear that any coherent approach to human action has to take account of all three of these aspects of morality. But the question of priority, of which one governs the others, is critical. I’m convinced that most ethical problems – both personally and in the public square – would become much more manageable if we had the big picture straight.
Duty and interest: how we think and how we act
When I ask a moral question, I tend to phrase it something like this: “What should I do?” or “What’s the right thing to do?” And the thing that makes me worry or question my decisions is usually a conflict between what I think I ought to do and what I want to do. I want another beer, but I promised to be the designated driver; I ought to treat my boss with respect, but I want to tell everybody what a jerk he/she is; I want that new smart phone, but I know I can’t afford the monthly payments; that sort of conflict.
That sense of duty is strongest (for me, at least,) in the little everyday decisions. I’ll ignore the duty to eat healthy food and get exercise, but I’ll feel guilty about it. When I’m in the checkout line, I don’t even think about not paying for the food or clothes or whatever I’ve bought. It’s a duty, after all.
But whenever I’m not strictly bound by duty, the sense of my own interest becomes more important. I ask, things like: “Do I want to marry this person?” or, “Do I want to take this job?” rather than, “Should I marry so-and-so?” or “Should I work for Mom & Pop Inc.?” The question of desire, of what is in my “best interest” seems to dominate in those kinds of decisions.
Duty is a category of justice: it tells us what we owe (what is due) to each other or, in a reflexive way, even to ourselves. It looks at the world in terms of what is required or necessary in any given situation.
Interest is more personal: it is focused on how to get what is best for me. My will, my desire, is the only standard it recognizes. It looks at the world in terms of what is desirable and possible.
In other words, duty doesn’t know how to deal with optional or free choices; and interest doesn’t know how to deal with obligations, seeing laws or rules merely as obstacles to be overcome. Stated this baldly, it’s pretty clear that neither duty nor interest works as a basis for moral life. But that doesn’t stop me from thinking in terms of duty and from acting in terms of my interests.
Love: forming and shaping desire
This is where the virtue of love shows its ability to support every aspect of human life. I’m not talking about the emotion of love, or affection, or being in love. Love as a virtue shows us the big picture of what is good in life.
Thomas Aquinas notes that “good” has two aspects: “One, the ultimate and universal good, the other proximate and particular.” Love is what shows us the ultimate good, and puts everything else in context. It’s like looking at the picture of a puzzle: it shows where each piece belongs.
If I love the environment, that shapes the kind of transportation I use and how I dispose of my trash and the kinds of things I eat and so on. If I love my spouse, then I look for things we can enjoy together and for ways I can contribute to his/her comfort and happiness.
Duty and interest are both important to help us make choices about particular goods. But Love knows when to call on them, how to balance them, how to choose in optional matters and how to accept obligations and requirements. Love shows us how to be fully ourselves, and fully human. That is why love is the form of all the other virtues.
