What this quote means

Ajdukiewicz's metaphor compares logic to a hygiene practice for the mind: it allows us to eliminate confused thoughts, fallacious reasoning, and harmful ideas. Just as we wash our hands to avoid disease, we use logic to avoid errors of judgment. It resonates in a world saturated with information and misinformation. It reminds us that clear thinking is a daily discipline.

How to apply it daily

Before sharing information, verify its source and the coherence of the reasoning, just as you would wash your hands before a meal.
