" It’s important to distinguish between explaining and excusing. Explaining why something happened is vital if you want to stop it from happening in the future. If a train derails, experts are going to do their best to determine what went wrong—they want to explain the wreck. The more accurately they can explain it, the better chance they have of making sure it doesn’t happen again. However, by explaining it they’re not lending it any kind of legitimacy or taking away from the tragedy of what happened. They’re just trying to understand why it happened.

The same is true for people. It’s possible that there’s no excuse for the behavior of someone you’re talking to on the other side. Okay, then. Don’t excuse it. But it’s still important to try to understand and explain why they do what they do—what they understand to be motivating their behavior—even if you completely disagree with their rationale. "
