Who is "the woman" and how does she help Marlow? What does Marlow mean by women are "out of touch with the truth?"Are "the women" specific...

"The Woman" is the queen of an African tribe. She is strong and unafraid, unlike others in her tribe who are afraid of the ship and its whistle. She and Kurtz live together in the time he is in the interior. She is a proud and "magnificent" woman.
As Kurtz leaves, she stands at the water's edge with her arms skyward, knowing she will never see him again.

The comment about women being "out of touch" is first said by Kurtz, and later repeated by Marlowe. It shows the view that women are innocent and unaware of life's harsh realities. Their nature cannot comprehend such issues that men are forced to endure.
