A historical sequence is said to be hyperfactual whenever it contains facts that have been proved to exist twice, that is, they exist under two alternative courses of events: the factual and the counterfactual. In such cases, we may verify whether multiple courses of action lead to the same outcome. Drawing upon an idea from Nelson Goodman, each section of this article highlights a different type of hyperfactual sequence: those resulting from the turbulence of historical turning points; those resulting from long term historical sequences; and those resulting from competing courses of action. The final section conveys how hyperfactuals represent the resistance of the multiple layers of history to the formalism of subjunctive conditionals.

只要历史序列包含事实已被证明存在两次的事实，就说它是超事实的，也就是说，它们在两种备选的事件过程中都存在：事实事实和反事实事实。在这种情况下，我们可能会验证多个行动方案是否会导致相同的结果。本文借鉴纳尔逊·古德曼（Nelson Goodman）的观点，着重介绍了另一种类型的超事实序列：那些由历史转折点的动荡产生的结果；长期历史序列产生的那些；以及因相互竞争的行动方针而产生的结果。最后一部分传达了超事实主义者如何代表历史的多个层面对虚拟语气条件形式主义的抵制。
