"Two kinds of blindness are easily combined, so that those who do not see really appear to see what is not"
About this Quote
The “two kinds” hints at a double failure that feels pointedly ancient and modern: intellectual incapacity joined to spiritual refusal. One is the limitation of the mind (not understanding); the other is the posture of the will (not wanting to understand). Put together, they produce a confident counterfeit: the dogmatist who cannot perceive reality but can manufacture convincing pictures of it. Tertullian’s verb choice matters: it’s not that the blind actually see; they “appear” to. He’s diagnosing rhetoric and social performance - how error becomes persuasive when it dresses itself in the language of certainty.
Contextually, this sits comfortably in early Christian polemic, where Tertullian is often sparring with pagans, heretics, and philosophers he suspects of mistaking verbal cleverness for truth. The subtext is a warning to his own side as well: the church isn’t immune to self-deception when zeal substitutes for discernment. The line works because it treats false belief as an active construction, not a passive mistake - a psychological technology that can turn absence into spectacle.
