The quote serves as a sobering tribute to the innumerable individuals who suffered and perished under ideological systems driven by rigid and absolutist beliefs. It underscores the often tragic consequences when political or social dogmas become impervious to critique or flexibility, particularly when these ideologies claim an unyielding historical inevitability. The mention of both fascism and communism suggests a condemnation of extremes on both ends of the political spectrum—systems that have, in various contexts, demanded unquestioning adherence and justified oppression or violence in the name of inevitable historical progress.

Reflecting on this from the standpoint presented in «The Call of the Tribe» by Mario Vargas Llosa, the quote resonates deeply with the author's concerns about ideological fanaticism and the suppression of dissent. Vargas Llosa frequently advocates for individual freedom, open debate, and skepticism towards absolute truths, especially when wielded to justify human suffering. This memorialization is a call to remember the human cost of rigid ideologies that see history as predetermined by inexorable laws, ignoring individual agency and moral complexity.

In a broader sense, the quote also prompts us to critically examine any contemporary political or social belief system that claims certainty about the course of history or humanity's destiny. Such beliefs risk repeating the mistakes of the past by dehumanizing those who resist or do not conform, often leading to oppression or violence. Ultimately, it is a remembrance that challenges us to value pluralism, empathy, and the protection of individual rights against any form of totalitarian determinism.
