Isn't this the truth?

"Among the immediate data of existence there is certainly no greater riddle for man that the fact of the existence of woman and the question as to her nature.  And on the other hand the same applies to women… To live humanly means never to escape the astonishment of one's own sex at the other, and the desire of one's sex to understand the other'

- Karl Barth (Church Dogmatics III.4, Pg., 167)
