"The discovery of truth is prevented more effectively, not by the false appearance things present and which mislead into error, not directly by weakness of the reasoning powers, but by preconceived opinion, by prejudice"
About this Quote
The subtext is characteristically Schopenhauerian: humans are not primarily truth-seeking animals but will-driven creatures, protecting comfort, status, and self-image. Preconceived opinion isn’t just a cognitive glitch; it’s a psychological investment. Once a belief becomes part of identity, counterevidence stops being information and starts being an insult. That’s why “false appearance” is almost a secondary problem; the deeper issue is selective attention, motivated interpretation, and the quiet veto power of “I already know.”
Context matters. Writing in a 19th-century Europe intoxicated with system-building philosophies and national mythmaking, Schopenhauer is skeptical of the era’s optimism about reason’s sovereignty. He’s also prefiguring a modern insight: bias is not the opposite of intelligence; it often recruits intelligence. The sentence reads like a warning label for any debate, newspaper, or feed: the obstacle isn’t that reality is hard to see. It’s that we keep looking with our verdict already written.
