‘Socialism today and tomorrow’ looks at tactics used to discredit socialism, throughout history and today. Is socialism still relevant? Do technological developments like automation threaten its future? What lessons should have been learned? Cooperation and social solidarity may be more important now than ever. Socialists still need to develop viable economic strategies and work towards genuinely democratic governments. Despite the difficulties in practice, 21st-century socialism should be internationalist. Modern socialists need to resist looking back at a ‘golden age’ of socialism but will still be able to learn positive lessons from the movements and utopias of the past.
