Wielka, większa i największa (Great, Greater, and Greatest) is a Polish science fiction young adult novel by Jerzy Broszkiewicz, published in 1960 by Nasza Księgarnia.

The protagonists experience three titular adventures – rescuing a kidnapped child, saving survivors from a plane crash, and finally, meeting aliens and diplomatically defending humanity from them.

[2][5][6][7]: 147–148 [8] The book's author, Jerzy Broszkiewicz, began writing in 1948; his works over time turned from biographies to science fiction, and were increasingly aimed at younger audience.

Her review was highly positive, praising the poetic mood of the novel, though she criticized the excessive "humanization" (anthropomorphization) of the car, Captain, as a minor flaw.

Jakubowski concluded that while the pedagogical and artistic dimensions of the novel could be further debated, it was "undoubtedly a very interesting and ambitious attempt at a modern book for young readers... combining elements of realism, science fiction, and philosophical-moral issues".

[28] In 1969, Kuliczkowska revisited the book, describing it as a poetic and engaging mix of realism and science fiction that addressed moral and philosophical problems.

[21] In 1983, Józef Zbigniew Białek [pl] noted that the book was praised for its intellectual and moral ambitions, and as a convincing introduction of children to contemporary issues.

[27] Słupska identified book themes such as youth's responsibility for the fate of the world, and the importance of ethical values such as kindness, nobility, and courage.

[5] Stefania Wortman [pl] also highlighted the novel's educational value, emphasizing the moral virtues (courage, loyalty, sacrifice, nobility, bravery) represented by the child protagonists.

[21] In 1983, he revisited the book, describing it as "didactic and philosophical... formally innovative and containing various narrative techniques, diverse genres, and literary conventions".

Here, the adult world "is tainted by evil (injustice, violence, lies)", and the burden of saving humanity falls on the shoulders of innocent youth.

[26] She also viewed the society of the Vegans as illustrating "the boldest dreams of an earthly paradise", where work was reduced solely to intellectual operations, as automation and robotics had eliminated the need for physical labor.

J. Słupska writing for Polonistyka [pl] in 1963 noted the novel message about benefits of peaceful nuclear energy, contrasted with the dangers of using atomic weapons.

[5] Niewiadomski and Antoni Smuszkiewicz [pl], writing in 1990, interpreted the book as a warning to adults about "the harmful direction of ethical and ideological evolution".

[34] In 2024, Piotr Konieczny of The Encyclopedia of Science Fiction similarly noted that the novel can also be read as a critique of the Cold War and nuclear weapons.

[26] In 1962, Jakubowski described the novel as one of the most interesting titles published in recent years by Nasza Księgarnia and expressed hope that the book represented the future of creative development of young adult literature.

[27] Kuliczkowska revisited the work in 1967, noting that it surprised critics with its quality and vision as "a piece firmly rooted in the realities of the contemporary world, multi-layered, with underlying themes"; she compared it to Porwanie w Tiutiurlistanie [pl] (The Abduction in Tiutiurlistan) by Wojciech Żukrowski from 1946.

[33] According to Dyduch, writing in 1991, "situated on multiple levels – realistic, fantastic, and futuristic – the parabolic novel by Broszkiewicz allows for unconventional analysis, serving the understanding of the modern novel, whose plot adheres to non-chronological orders".

Analyzing the novel's narrative, she emphasized the importance of the travel motif, which stimulates children's imagination, focusing on positive, optimistic thinking about the future.

However, he also observed that the book innovativeness and uniqueness in the Polish youth literature had a downside, as it led some teachers and students to consider the book "difficult", which he attributed to a lack of understanding of the concept of fiction writing among the young readers due to the dominance of realistic and documentary works in the Polish reading canon, as well as the simultaneous lack of experience in interpreting science fiction literature among both youth and educators.

[2][37] In 2008, Maria Ostasz observed that the work was "innovative in terms of the artistic conventions used and the boldness of its axiological message", noting that the author "completely departed from the realistic convention" and "effectively combined the poetics of fairy tales with science fiction, giving the adventure-thriller novel a completely new character – a parable about humanity as responsible for the fate of the world".
