"When a torrent sweeps a man against a boulder, you must expect him to scream, and you need not be surprised if the scream is sometimes a theory"
About this Quote
The intent isn’t anti-intellectual so much as anti-pretense. He’s warning readers to treat certain doctrines - moral systems, political programs, even fashionable philosophies - as responses to pressure before they’re treated as timeless truths. It’s a line about the psychology of explanation: when life is violent or chaotic, people reach for a narrative that gives the collision meaning. “Theory” becomes a way to metabolize fear, humiliation, or helplessness into coherence. The subtext is compassion laced with skepticism: don’t mock the scream, but don’t mistake it for a map of the river.
Context matters. Stevenson wrote in an age when scientific certainty, social Darwinism, and ideological confidence were booming alongside brutal class realities and empire. As a novelist who understood both adventure and fragility - and as someone chronically ill - he knew how often belief is forged under duress. The line doubles as a reader’s tool: when you encounter a grand explanation, ask what torrent it came from, what boulder it hit, and what kind of scream it had to become.
