or less learned discourse. One would like to know what he actually did say, and what he thought of it all afterwards!
In the meanwhile his time must have been fully occupied. He was at school from 8 till n each morning, and from 2 till 5 in the afternoon on weekdays; and some of the hours when he was not at school were occupied in school preparation, and also in the study of secular subjects under a private teacher or teachers. Most probably he continued to study at the Jewish school or academy until he was eighteen, so as to give him an opportunity to develop that uncommon ability of which he showed unmistakable signs at the age of fifteen in the perplexing questions which he asked of Rabbi Morteira. At eighteen it was high time to think of a means of livelihood. His brother, or half-brother, Isaac died just about that time. His father may have thought of taking him into business. But Spinoza's tastes did not lie in the direction of business. He preferred to seek the means of support in some occupation that would keep him in touch with science and scholarship. This probably determined him to learn the art of polishing lenses, which was taken up by many learned men of his generation. By that time he may already have shown some of his heretical tendencies, and these may have given rise to some little friction at home. Possibly this was the reason why his half-sister Rebekah and his brother-in-law de Casseres tried soon afterwards to exclude him from his share of the property which his father left when he died. Spinoza, however, could scarcely have been so inconsiderate as to cause his father unnecessary pain, and most probably he kept most of his doubts to himself, and remained in his father's house so long as his father lived, that is to say, till March 1654, when he was in his twenty-second year.
