In Samuel Beckett's works, particularly in "Nohow On," themes of perception and existence are intertwined. The phrase highlights the contrasting perceptions of color and absence, portraying a landscape rich with existential dread while depicting the struggle between visibility and invisibility. The character's longing to escape from reality suggests a deep sense of despair and a desire to be absolved from the burdens of existence.

Beckett’s reflections on black, white, and the void resonate with a sense of hopelessness. The notion of letting someone or something vanish underscores a yearning for freedom from suffering and the complexities of life. This intense emotional landscape challenges readers to confront the uncomfortable truths of their own perceptions and the human condition, ultimately signaling a profound exploration of existence and oblivion.
