在整个科学世界概念的起伏中，始终存在着一个人类推理可以理解的世界的愿景。在当代递归理论的理解中，术语“推理”可以解释为“建设性的”，或者更具体地说，是“机械可计算的”。这一说法的一种表述是假设我们的宇宙是由某种确定性计算代理的行动产生的；或者，尖锐地说，我们生活在计算机生成的宇宙中。然后，物理学沦落到对特定虚拟现实--恰好是我们的宇宙--的内在“内在观点”的研究上。在这种解释中，形式逻辑、数学和计算机科学只是更一般的“虚拟”现实的物理科学，无论它们是否“真正”实现。我们将研究这个概念的几个方面，其中一个猜想是，物理学中的随机性可以被建设性地重新解释为对应于数学中的不可计算和不可判定。我们还将通过揭示经典物理的不一致性来攻击它的非建构性。另一个令人关注的问题是接口的建模，即两个宇宙之间通信的手段和方法。在推测层面上，这可能会为诸如“奇迹”的发生或“心身问题”等臭名昭著的问题提供一些线索。
Throughout the ups and downs of scientific world conception there has been a persistent vision of a world which is understandable by human reasoning. In a contemporary, recursion theoretic, comprehension, the term “reasoning” is interpretable as “constructive” or, more specifically, “mechanically computable.” An expression of this statement is the assumption that our universe is generated by the action of some deterministic computing agent; or, stated pointedly, that we are living in a computer-generated universe. Physics then reduces to the investigation of the intrinsic, “inner view” of a particular virtual reality which happens to be our universe. In this interpretation, formal logic, mathematics and the computer sciences are just the physical sciences of more general “virtual” realities, irrespective of whether they are “really” realized or not. We shall study several aspects of this conception, among them the conjecture that randomness in physics can be constructively reinterpreted to correspond to uncomputability and undecidability in mathematics. We shall also attack the nonconstructive feature of classical physics by showing its inconsistency. Another concern is the modeling of interfaces, i.e., the means and methods of communication between two universes. On a speculative level, this may give some clue on such notorious questions such as the occurrence of “miracles” or on the “mind-body problem.”
