Is open-mindedness a moral virtue? Surprisingly, this question has not received much attention from philosophers. In this paper, we fill this lacuna by arguing that there are good grounds for thinking that it is. In particular, we show that the extant account of open-mindedness as a moral virtue faces an objection that appears to show that exercising the character trait may not be virtuous. To offset this objection, we argue that a much stronger argument can be made for the case that open-mindedness is a moral virtue by appealing to the notion of moral understanding. Specifically, we provide a new rationale as to why we should exercise open-mindedness and offer several arguments to allay the concern that doing so can at times cause us to be in an epistemically and morally weaker position.

豁达是一种道德美德吗？

豁达是一种道德美德吗？令人惊讶的是，这个问题并没有受到哲学家们的太多关注。在本文中，我们通过论证有充分的理由认为它存在来填补这个空白。特别是，我们表明，将思想开放作为一种道德美德的现存解释面临着一个反对意见，该反对意见似乎表明，行使这种性格特征可能不道德。为了抵消这一反对意见，我们认为，通过诉诸道德理解的概念，可以对思想开放是一种道德美德的情况提出更有力的论据。具体来说，我们提供了一个新的理由来解释为什么我们应该保持开放的态度，并提供一些论据来减轻人们的担忧，即这样做有时会导致我们在认识上和道德上处于弱势地位。
