Introduction
Central question
Why have socialism and anarchism become plausible mass movements, and what should a serious reader expect from them?
Main argument
Russell opens by treating utopian social thought as old, but modern socialism and anarchism as new in one decisive respect: they are linked to organized movements and to the actual suffering of wage-earners. He frames the book as an attempt to separate the genuine moral impulse behind radical reform from the caricatures that reduce it to violence, dogma, or mere resentment.
He also signals the book's practical angle. Rather than asking which doctrine is purest, he asks which arrangements would actually make people freer and happier. That concern governs the whole work.
Key ideas
- Radical reform comes from sympathy with social suffering, not from abstract theory alone.
- Socialist and anarchist ideas matter because they became tied to labor organization.
- Syndicalism is treated as anarchism adapted to trade-union life.
- The book will judge systems by human consequences, not slogans.
Key takeaway
The introduction establishes the book's standard: ideas about society must be tested against freedom, organization, and real human welfare.
