"The limits of the possible can only be defined by going beyond them into the impossible"
About this Quote
The cleverness is the pivot from definition to action. “The limits of the possible” sounds like something you’d measure with instruments or prove with a theorem. Clarke refuses that comfort. Limits are not discovered; they’re stressed, negotiated, sometimes shattered. The phrase “going beyond them” frames progress as a willful, almost athletic act, not a passive accumulation of facts. And “into the impossible” isn’t a mystical realm so much as a temporary holding pen for ideas that haven’t yet earned bureaucracy’s permission.
Subtext: risk is not an unfortunate byproduct of innovation; it’s the method. Clarke is also smuggling in an ethic for artists and scientists alike. If you only work where outcomes are guaranteed, you’ll never learn where the guarantees were flimsy. The sentence flatters audacity, but it also warns against timidity dressed up as realism.
Context matters: coming from a science-fiction writer who collaborated with real engineers and wrote during the space age, the quote is both prophecy and self-justification. Science fiction becomes not escapism, but a pressure test for the boundaries everyone else treats as fixed.
