Those sentences are meaningless nonsense.

Not that I'm defending this viewpoint, of course, but it is far from meaningless. Bearing children is quite literally the value of a woman - in most societies "that do not derive from the Enlightenment", as Eliezer would say. A barren woman is worthless and therefore not a woman at all, in the important sense - she is not a functional woman.

To a majority of all men who ever lived, and probably to most women who lived with them, "the value of a woman is in bearing children", or "bearing children is what makes a human being a woman", are nearly tautologies. You should not be surprised to encounter such statements. (Ugh field optional.)
