The ancestral voices were prophesying war because ancestral voices never shut up, and they hate to be wrong, and war is a sure thing, sooner or later.
The quote reflects the idea that ancestral voices, representing history, experience, and wisdom, continuously speak to us about the inevitability of conflict. These voices symbolize the lessons learned from past generations, which often highlight the recurring patterns of human behavior. Their constant chatter suggests that history tends to repeat itself, and war is a frequent outcome of underlying tensions and unresolved issues.
This perspective implies that the knowledge passed down through generations is often ignored or dismissed, yet it remains relevant. The notion that these voices "hate to be wrong" underscores a fatalistic view: despite efforts to avoid war, it is presented as an unavoidable outcome, reinforcing the cyclical nature of history where the past inevitably influences the present and future.
