and analytical mind to deep reflection and meditation. The natural sciences, mathematics, and physics, which he pursued with devotion, and the new-born, imposing philosophy of Descartes (Cartesius), for which his mind had special affinity, extended his circle of vision and enlightened his judgment. The more he imbibed ideas from various sources, assimilating them with those innate in him, and the more his logical understanding developed, the more did he become alienated from Judaism, in its Rabbinical and Kabbalistic trappings, and love of Van den Enden's learned daughter was not needed to make him a pervert from Jewish belief. Independent, judicial reason, which disregards what is traditional or hallowed by time, and follows its own laws, was his mistress. To her he dedicated pure, undivided worship, and she led him to break with inherited views. All that cannot be justified before the inexorable tribunal of clear human vision, passed with him for superstition and clouded thought, if not actual frenzy. His ardent desire for truth, pure truth and certainty, led him to a complete breach with the religion endeared to him from childhood; he not only rejected Talmudical Judaism, but also regarded the Bible as the work of man. The apparent contradictions in the books of Holy Scripture appear to have first raised his doubts as to their inspiration. It must have cost him a hard struggle to give up the customs and opinions endeared to him through manifold ties, and to become, to a certain extent, a new man. For Spinoza was quite as much a moral character as a deep thinker. To hold anything as false in theory, and yet from fear, custom, or advantage to adopt it in practice was impossible for him. He was differently constituted to his revered master Descartes, who kept away from the church the torch of truth which he had kindled, made a gap between theory and practice to avoid offending that church, and, for example, vowed a pilgrimage to our Lady of Loretto for the success of his system and its destructive tendency. According to Spinoza's idea every action ought to be a true reflection of reason. When he could no longer find truth in Judaism, he could not bring himself to follow its ritual precepts. He ceased to attend the synagogue, cared no longer for the Sabbath and the festivals, and broke the laws concerning diet. He did not confine himself to the renunciation of Judaism, but imparted his convictions to young men who sought his instruction.
