Book of Disquietude

by Roberto Bolaño

Like Soares, Bolaño's narrators are obsessed with tracking something elusive—in this case, a mysterious poet—across fragmented testimonies and digressive monologues that circle back on themselves. Both books treat the search for identity and meaning as more important than any resolution, and both authors use their prose style itself as a character grappling with existence.

by Samuel Beckett

Beckett's protagonist narrates his own dissolution with the same circular, obsessive quality as Soares—returning again and again to the question of who he is and whether his memories are even real. The prose itself becomes a maze of contradictions and retractions, mirroring the impossibility of self-knowledge that haunts the Book of Disquietude.

by Italo Calvino

This is a surprise pick, but Calvino shares Pessoa's fascination with fractured identity and multiple selves—here, the reader becomes a character navigating through incomplete narratives and shifting perspectives. Where Pessoa uses heteronyms to explore consciousness, Calvino uses metafiction to make you experience the vertigo of not knowing who 'you' are in a text.

by Unknown

Published in 1925, this earlier modernist work shares Pessoa's interest in authenticity versus artifice—Gide's characters are constantly performing versions of themselves, and the novel itself contains a novel-within-a-novel, creating the same hall-of-mirrors effect you find in Soares's heteronymic existence. Both authors ask: what remains when we strip away all the masks?

by Winfried Georg Sebald

Sebald's narrator wanders through landscape and memory in a state of profound melancholy, accumulating observations and digressions that feel less like a plot and more like consciousness itself—much like Soares's entries. Both writers use fragmentation and tangential thinking to capture the texture of being alive and uncertain, and both pair sparse, meditative prose with an almost archaeological attention to forgotten details.
