What this quote means

Lang's scathing formula condemns gullibility and reliance on irrational beliefs. Superstition, whether religious, popular, or modern, fills a void in those who do not seek to understand the world through reason. It reveals a weakness of mind, not limited intelligence, but intellectual laziness or fear of the unknown. Lang urges us to cultivate our critical spirit and prefer analysis to blind belief.
