Abstract: Cosmologists often use certain global properties to exclude ''physically unreasonable'' cosmological models from serious consideration. But, on what grounds should these properties be regarded as ''physically unreasonable'' if we cannot rule out, even with a robust type of inductive reasoning, the possibility of the properties obtaining in our own universe?
