François Hemsterhuis (1721-1790) was the most significant Dutch philosopher after Spinoza.Daniel Whistler argues that Hemsterhuis’ philosophy matters and that its exclusion from the canon of modern philosophy has been unjust.This is not just because of its reception history - its influence on later German thinkers, such as Goethe, Hamann, Hegel, Herder, Hölderlin, Jean Paul, Kant, Jacobi, Novalis, Schelling, the Schlegels, Schleiermacher, Wieland - but is primarily because Hemsterhuis’ philosophy contains a rich assemblage of ideas and philosophical practices.Whistler looks specifically at Hemsterhuis’ reflections on philosophical style and the strategies he employs to communicate ideas in his late dialogues.Taking seriously Hemsterhuis’ newly-published complete correspondence as a significant philosophical text, he contends that Hemsterhuis deserves to be placed alongside Shaftesbury, Hamann, Friedrich Schlegel, Kierkegaard and Nietzsche as one of the preeminent philosophical stylists of modernity.
