What central idea or theme does the speaker develop by referring to his soul in stanzas 1 and 4? Here is the Poem Out of the night that covers me,
Black as the Pit from pole to pole,
I thank whatever gods may be
For my unconquerable soul.

55In the fell clutch of circumstance
I have not winced nor cried aloud.
Under the bludgeonings of chance
My head is bloody, but unbowed.

Beyond this place of wrath and tears10 10Looms but the Horror of the shade, And yet the menace of the yearsFinds, and shall find, me unafraid.

It matters not how strait the gate,
How charged with punishments the scroll.
1515I am the master of my fate:
I am the captain of my soul.
