A middle fact is a true proposition about what would have happened had A been true (where A is in fact false), whose truth isn't entailed by any non-counterfactual facts. I argue that there are no middle facts; if there were, we wouldn't know them, and our ignorance of them would result in ignorance about whether regret is fitting in cases where we clearly know it is. But there's a problem. Consider an unflipped fair coin which is such that no non-counterfactual fact determines that it would have landed heads had it been flipped (or tails had it been flipped). If there are no middle facts, it's not true that it would have landed heads had it been flipped nor that it would have landed tails had it been flipped. Yet each counterfactual is still possibly true for all we know. I argue that we can resolve this tension in the anti-middle fact position, further strengthening the case against middle facts.

中间没有事实

中间事实是关于如果A为真会发生什么的真命题（其中A实际上是错误的），其真实性不被任何非反事实事实所蕴含。我认为没有中间事实；如果有，我们就不会知道它们，而我们对它们的无知会导致我们不知道后悔是否适用于我们清楚知道的情况。但是有一个问题。考虑一个未翻转的公平硬币，没有非反事实事实确定如果翻转它会正面朝上（或者如果翻转它会出现反面）。如果没有中间事实，那么如果它被翻转它就不会是正面的，如果它被翻转它也不会是反面的。然而，就我们所知，每个反事实仍然可能是正确的。我认为我们可以在反中间事实的立场上解决这种紧张关系，进一步加强反对中间事实的论据。
