A quick and dirty definition of love, according to Thomas Aquinas, is “to will the good of another.”
This even works for loving oneself, if what you’re willing is really what is good for yourself – that is, what will make you the best person you can be, rather than what simply feels good at the moment.
The trick is, how do you know what’s really good for someone? Isn’t it just arrogant beyond belief to think that I know better than anyone else what’s best? Isn’t it horribly patronizing? Doesn’t it belittle the person I’m supposedly loving?
How to know what’s good
Well, think of the alternative for a moment. Wouldn’t it be a false “humility” to neglect to do nice things for a friend, or to refuse to warn someone of a danger, on the excuse that “I can’t really know what’s good for so-and-so”?
There is a danger of arrogance or a false “superiority,” because we can only judge based on our own perceptions. We can be deceived by apparent goods, or by the illusion of ease or safety. We can be blinded or distracted from what’s really going on.
But none of this means that we’re incapable of recognizing real good things when we meet them. It just means there are limits, and that we therefore need each other’s help.
I’ve found in my own life that the best way to know what’s really good – and therefore what’s really loving – is to double-check with someone I trust. Sometimes, I talk to my mom. Sometimes, to one of my close friends. For some situations, I ask a priest or a counselor.
In other words, when I’m not sure how to love, I ask someone with a different perspective than mine. I ask them to love me, by helping me to love someone else. I don’t always do what they advise, but their point of view gives me a better picture of what’s real, and helps me sort out the real good from apparent goods.
Knowing love and doing love
Of course, actions speak louder than words. This is where the other virtues come into play. I need temperance to work when I need to work so that I can play when my friends are available to play. I need courage to stand my ground when I’m tempted to give in. I need justice to remember and to guide me in my obligations toward others. I need prudence to figure out how to put my knowledge and my love into practical action in the first place.
So, if love is willing someone’s good, then all the other virtues are the tools that help me to accomplish that will. They enable me to actually do good, rather than just thinking or desiring it.
And that’s encouraging, because I often mess up the doing part. But if I learn, and practice, and continue to grow in virtue, then I’ll come closer to that ultimate goal of loving my family, my friends, my neighbors.
