Spinoza (1632-1677), the great Dutch philosopher, had a life almost entirely devoid of interest, which makes a biographer's task difficult. This author shows him to be in almost every way admirable and lovable. He earned his living polishing lenses while he corresponded with other philosophers, and discussed philosophy in a small circle of enlightened friends. Dr Gullan-Whur turns with enthusiasm to his intellectual life, very clearly explains the reasons for Spinoza's religious doubts and his excommunication by his fellow Jews, and amply demonstrates the formidable difficulties of his great work, the Ethics, with its axioms and propositions, its geometrical design, and his exploration of the question of the legitimacy and scope of metaphysical speculation.
