"Begin challenging your own assumptions. Your assumptions are your windows on the world. Scrub them off every once in awhile, or the light won't come in"
About this Quote
The intent is quietly radical because it reframes certainty as clutter. Assumptions aren’t treated as beliefs you heroically defend, but as surfaces that inevitably gather grime: bias, habit, the lazy shortcuts our brains prefer. “Scrub them off every once in awhile” lowers the temperature of ideological combat. It suggests that the problem isn’t that you’re uniquely wrong; it’s that you’re human, and humans accumulate smudges.
Subtextually, Alda is also selling humility without the piety. Windows don’t generate light; they admit it. That implies a world full of information, other people’s experiences, inconvenient data - but you only get access if you do the unglamorous work of cleaning your lens. Coming from an actor famously associated with communication (and later, science communication), the line reads as a plea for better listening: clarity isn’t just about speaking well, it’s about keeping your perception usable. The warning is simple and a little chilling: you can live in daylight and still choose dimness, one unexamined assumption at a time.
