In "Darker Than You Think" by Jack Williamson, the author presents a perspective on materialism, contrasting his own views with the approach of law enforcement. He identifies as a strict materialist, suggesting a philosophical grounding in the belief that only material or physical things truly exist. This stance highlights a certain pragmatism in understanding the world based on tangible evidence.

However, Williamson also critiques the police, labeling them as "brutal materialists." This term implies that, while they may focus on the physical aspects of reality, their methods can be harsh and oppressive. The quote underscores a tension between a rational, materialistic worldview and the often violent realities of enforcing order, revealing a deeper commentary on society’s treatment of both individuals and ideas.
