Vacío perfecto (Biblioteca del Siglo XXI)

Lem's concept of reviewing nonexistent books adds a layer of philosophical complexity. I wonder what led him to this metafictional approach.

The book cleverly exposes the pretensions of literary critics, but it also made me question how much of our own judgments are influenced by biases.

The philosophical undertones are quite evident, and I'm curious how Lem's personal interests influenced the way he constructs these layered critiques.
