"Beware of false knowledge; it is more dangerous than ignorance"
About this Quote
The line carries the dramaturgist’s instinct for social mechanics. Shaw watched modernity invent new authorities - scientific, bureaucratic, journalistic - and he distrusted how easily their language could be performed. “False knowledge” is a kind of costume: it lets the speaker occupy the role of the expert, collect deference, and shut down argument. Ignorance, at least, can be admitted; false knowledge resists correction because it comes pre-loaded with status and certainty.
Subtextually, it’s a jab at respectable complacency. The danger isn’t only error; it’s error that has been institutionalized, repeated until it becomes common sense. Shaw, a contrarian with a taste for puncturing Victorian pieties, is pointing at the moral comfort that comes from having “the facts” on your side - even when those facts are just prejudice in lab-coat form.
Context matters: an era of rising professionalization and ideological crusades, when confident half-truths could steer public health, economics, and empire. Shaw’s line still reads like a diagnostic for our information economy: misinformation isn’t persuasive because it’s subtle, but because it’s certain.

Evidence: A learned man is an idler who kills time with study. Beware of his false knowledge: it is more dangerous than ignorance. (Appendix: 'Maxims for Revolutionists' → 'EDUCATION' (page number varies by edition)). This line appears in Shaw’s play Man and Superman inside the appended text 'The Revolutionist's Handbook' → 'Maxims for Revolutionists' under the heading 'EDUCATION'. The commonly-circulated shorter form ('Beware of false knowledge; it is more dangerous than ignorance') is a truncated version that drops the preceding sentence and changes 'his false knowledge' to 'false knowledge.'
