"The presentations and conceptions of the average man of the world are formed and dominated, not by the full and pure desire for knowledge as an end in itself, but by the struggle to adapt himself favourably to the conditions of life"
About this Quote
The intent is partly epistemological and partly cultural. As a physicist-philosopher working in the late 19th century, Mach was pushing against metaphysics and against the heroic myth of pure reason. His broader project treats concepts as economical summaries of experience, not divine revelations. Here, the subtext is Darwinian without needing to name Darwin: beliefs persist because they help you manage work, status, danger, and social friction, not because they’re pristine or complete. “Full and pure desire” is framed like an ideal so rare it borders on fiction.
Context matters: this is modernity talking to itself after industrialization, mass politics, and the professionalization of science. Mach knows that even science isn’t immune to comfort-seeking abstractions and prestige-driven orthodoxies. The line lands because it implicates everyone while pretending to observe “the average man.” It’s a mirror offered at arm’s length: you can laugh at the crowd, then realize you’re in it, using ideas less to see clearly than to land safely.
