Final answer:
Without the specific context of Dickinson's "The Soul unto itself," it's not possible to definitively answer which two roles the soul plays according to the speaker.
Step-by-step explanation:
The poem "The Soul unto itself" by Emily Dickinson explores the complex nature of the soul. Unfortunately, the excerpts and references provided do not explicitly identify the two roles the speaker associates with the soul in this specific poem. Therefore, without the correct poem context, it is not possible to accurately answer which two roles the soul plays according to the speaker in "The Soul unto itself."
However, Dickinson's poetry often portrays the soul as introspective and self-sufficient, hinting at themes of identity and inner strength. It is essential to consult the actual text of "The Soul unto itself" to determine the roles mentioned.
