当前确定性宇宙学的基本假设，即所谓的宇宙学原理，只能用概率概念来精确地表述。因此，如果决定论被抛弃，而代之以坦率的概率宇宙论，那么可以预期会有相当大的进步和美学收获。这就需要采纳这样的观点，即宇宙是一个随机过程的实现，它在三个（空间）坐标上是静止的（宇宙学原理），也可能在第四个（时间）坐标上是静止的（“完美”宇宙学原理）。给出了两个例子，确定性的宇宙学理论，逃避确定性的治疗有关的问题，但借给自己一个不确定性的统计研究。
Thebasic hypothesis underlying current deterministic cosmologies, namely the so-called cosmological principle, can be stated precisely only in terms of probabilistic concepts. Consequently, considerable progress and aesthetic gain may be expected if determinism is abandoned and replaced by a frank probabilistic treatment of cosmology. This requires the adoption of the view that the Universe is a realization of a stochastic process which is stationary in the three (spatial) co-ordinates (cosmological principle) and possibly also stationary in the fourth (time) co-ordinate (“perfect” cosmological principle). Two examples are given of problems relevant to deterministic cosmological theories that elude deterministic treatment, but lend themselves to an indeterministic statistical study.
