Spinoza in Germany presents fifteen newly commissioned essays by a distinguished set of international experts examining the legacy and influence of Spinoza on German thought in the long nineteenth century. The focus on Spinoza's influence illuminates both the nature of his philosophical contribution, as well as novel aspects of the philosophical lineage from idealism to Marxism, psychoanalysis, and beyond. The chapters are at the cutting edge of research on modern German thought, not only concerning canonical figures like Herder, Kant, and Marx, but also thinkers whose importance has since been neglected such as Salomon Maimon and Lou Salome.
