الإنسان الحر لا يفكر في الموت إلا أقل القليل؛ فحكمته تسوقه إلى إمعان التفكير في الحياة، لا الموت. - Benedictus de Spinoza

...Yes, you must read Spinoza. Those who accuse him of atheism are asses. Goethe said, 'When I am upset or troubled I reread the Ethics.' Perhaps like Goethe you will find calm in the reading of this great book. Ten years ago I lost the friend I had loved more than any other, Alfred Le Poittevin. Fatally ill, he spent his last nights reading Spinoza. [Original in French: A propos de Spinoza (un fort grand homme, celui-là), tâchez de vous procurer sa biographie par Boulainvilliers. Elle est dans l'édition latine de Leipsick. Emile Saisset a traduit, je crois, l'Éthique. Il faut lire cela. L'article de Mme Coignet, dans la Revue de Paris était bien insuffisant. Oui, il faut lire Spinoza. Les gens qui l'accusent d'athéisme sont des ânes. Goethe disait: « Quand je me sens troublé, je relis l'Éthique ». Il vous arrivera peut-être, comme à Goethe, d'être calmée par cette grande lecture. J'ai perdu, il y a dix ans, l'homme que j'ai le plus aimé au monde, Alfred Le Poittevin. Dans sa maladie dernière, il passait ses nuits à lire Spinoza.]

[Nietzsche and Spinoza: Enemy-Brothers] Amor fati—love of fate—is the defiant formula by which Nietzsche sums up his philosophical affirmation. The term, never before used in philosophy, is clearly a polemical transformation of Spinoza's amor dei intellectualis, rejecting the primacy of the intellect and putting fatum (fate) in place of Spinoza's nature-God as the object of love. The pair amor dei and amor fati provides an apt verbal representation of the complex relationship between Nietzsche and Spinoza, the two enemy-brothers of modern philosophy. Perhaps no two philosophers are as akin as Spinoza and Nietzsche, yet no two are as opposed. If Spinoza initiated the modern philosophy of immanence and undergirds it throughout, then Nietzsche brings it to its most radical conclusion—and, as we shall see, turns this conclusion against Spinoza himself. Nietzsche explicitly recognizes his debt and kinship to Spinoza. Speaking of his "ancestors," Nietzsche at various times gives several lists, but he always mentions Spinoza and Goethe—and always as a pair. This is no accident, for Nietzsche sees Goethe as incorporating Spinoza and as anticipating his own "Dionysian" ideal.
