In "Use of Weapons" by Iain M. Banks, the narrative explores the nature of belief and the motivations behind human actions. The protagonist reflects on how people's beliefs often stem from instinct rather than careful reasoning. This perspective suggests that many convictions are not the product of rational thought but rather an innate sense of what feels correct to them.

This observation raises questions about the authenticity and depth of our beliefs. It implies that individuals may hold onto ideas or ideologies simply because they resonate with their internal feelings, leading to an instinctual rather than intellectual foundation for their worldview. This insight challenges readers to examine the strength and origins of their own beliefs and the implications of acting on instinct without critical analysis.
