The real gift here isn't tolerance—it's intellectual agility. Aristotle distinguishes between *understanding* something fully and *believing* it, a gap most people never bother crossing. When you can genuinely inhabit another's reasoning, feel its logic from the inside, you've done the harder work than simply dismissing it or accepting it wholesale. A good scientist reading a flawed study, a parent listening to their teenager's worldview, a reader of opposing political arguments—these people aren't just being polite. They're training their minds to separate comprehension from capitulation, which is how we actually learn rather than merely accumulate opinions.
