In such social and intellectual atmosphere Spinoza grew up. Of his early life, practically nothing is known. His parents, we know, were at least fairly well-to-do, for Spinoza received a good education. And we know that he was, when about fifteen years of age, one of the most brilliant and promising of Rabbi Saul Levi Morteira's pupils. Everyone who then knew Spinoza expected great things of him. He proved himself to be a very acute rabbinical student; at that early age already somewhat too critical, if anything, to suit the orthodox. But all felt reasonably confident he would become a distinguished Rabbi, and perhaps a great commentator of the Bible. Of course, of the orthodox sort. But the Rabbis were early disillusioned. Spinoza soon found the learning of the Synagogue insufficient and unsatisfactory. He sought the wisdom of secular philosophy and science. But in order to satisfy his intellectual desires it was necessary to study Latin. And Latin was not taught in the Synagogue. An anonymous German taught Spinoza the rudiments of the language that was to enable him to enter into the important current of modern ideas especially embodied in the philosophy of Descartes. Francis Van den Ende gave him a thorough technical, not literary, mastery of it. And Van den Ende taught Spinoza much more besides. He acquainted him with the literature of antiquity; he gave him a sound knowledge of the contemporary fundamentals of physiology and physics; and it was he possibly, who introduced him to the philosophy of Descartes and the lyrical philosophic speculation of Bruno. He did much also (we may easily infer) to encourage the independence of mind and the freedom in thinking Spinoza had already manifested in no inconsiderable degree. For although this Van den Ende was a Catholic physician and Latin master by profession, he was a free thinker in spirit and reputation. And if we are to believe the horrified public suspicion, he taught a select few of his Latin pupils the grounds of his heterodox belief. As one can easily understand, to study Latin with Van den Ende was not the most innocent thing one could do. Certainly, to become a favorite pupil and assistant teacher of Van den Ende's was, socially, decidedly bad. But Spinoza was not deterred by the possible social consequences of his search for knowledge and truth. He took full advantage of his opportunities and did not hesitate to follow wherever his master might lead.
