“Knowledge without judgment is a double folly.”Baltasar Gracián · Oracolul manual · 1647 · Aforismul 4
Knowledge without discernment does not lead to wisdom, but amplifies errors.
Gracián warns that accumulating knowledge without the ability to evaluate it leads to poor decisions. A scholar lacking judgment can defend absurdities with sophisticated arguments, deceiving even more. Example: an economist who knows all theories but cannot recognize the real context of a crisis. Knowledge becomes a dangerous weapon when not paired with practical wisdom.
Why it matters In the age of abundant information, this maxim teaches you to filter and think critically. It's not how much you know, but how you use what you know.
