Final answer:

Kincaid defines the widening and darkening space as a room or darkened rooms that serve as an artist's private and creative sanctuary.

Explanation:

Kincaid's concept of the expanding and darkening space, as described in the given context, refers to the room or darkened rooms. These spaces become a canvas for the artist's imagination to roam freely, birthing ethereal figures that find their way onto his paintings. The dark room, in this context, symbolizes more than mere physical space; it embodies a private sanctuary where creativity blossoms.

It serves as the backdrop for the artist's introspective journey, a retreat into the depths of his thoughts, free from external distractions. Within this secluded realm, artistic expression takes form, and ghostly entities materialize, reflecting the unbridled creativity that flourishes in the embrace of solitude. Kincaid's exploration of this evolving and darkening space underscores the profound connection between the artist's surroundings and the ethereal creations that emerge from the depths of his contemplative retreat.
