because a man glances up at the sky at night does not make him an astronomer, you know.' Bruno
Bruno's quote highlights that simply observing something, like gazing at the night sky, does not automatically make someone an expert or someone with deep understanding. It emphasizes the difference between casual observation and active knowledge or expertise in a subject.
This underscores the idea that true understanding requires more than just superficial interest; it involves learning, studying, and engaging deeply with the subject matter, rather than just admiring it briefly or casually.
