[Evisse the Blue]

There are more examples of foresight, even among less wise and mere mortals, which would appear to suggest that it is a gift from Eru rather than a personal ability. For instance, Theoden's 'heart' tells him that he will not see Aragorn again after he leaves for the Paths of the Dead, and this indeed proves true; but the reason for it is not revealed to him: Theoden assumes it is Aragorn who would die, when instead it is he that meets his end before he can see Aragorn again.
Another example is Hurin and Morwen talking about the future of their children, and each of them feels a strange foreboding at the plans that the other had made, but not at their own. It turns out that they were both right, but because their foresight was limited, they could do nothing about it.
