What does that quote indicate to us?

One can read, as I read when I was a boy, the brochures about lovely South Africa, that land of sun and beauty sheltered from the storms of the world, and feel pride in it and love for it, and yet know nothing about it at all. It is only as one grows up that one learns that there are other things here than sun and gold and oranges. It is only then that one learns of the hates and fears of our country. It is only then that one's love grows deep and passionate, as a man may love a woman who is true, false, cold, loving, cruel and afraid. chapter 24
