真理 (zhēnlǐ) carries significant weight in Chinese thought, far beyond a simple “true/false” dichotomy. It's a cornerstone concept in philosophy and politics.
You will encounter 真理 (zhēnlǐ) in formal, academic, and rhetorical contexts. It is rarely used in casual, everyday conversation.
The most common mistake for English speakers is using 真理 (zhēnlǐ) for everyday, factual truths. It is a “false friend” to the broad English word “truth” in this sense.
