excite the sympathy of his contemporaries and posterity, he wrote his autobiography and confession, which, however, contain no new thoughts, only bitterness and furious attacks against the Jews, intermingled with fresh aspersions of them in the eyes of Christians: that even at this time they would have crucified Jesus, and that the state ought not to grant them freedom of religious profession. This document, drawn up amidst preparations for death, breathed nothing but revenge against his enemies. After he had finished his impassioned testament, he loaded two pistols, and fired one at his relative, who was passing his house. He missed his aim, so he shut the door of his room, and killed himself with the other weapon (April, 1640). On opening his residence after the report of the shot, they found on the table his autobiography, "An Example of Human Life," in which he brought Jews and Judaism to the bar, and with pathetic sentences described them as his excited imagination in the last hour suggested. By this act and legacy Da Costa showed that he suffered himself to be overpowered by his feelings rather than guided by reason. He was neither a thinker nor a wise man, nor was his a manly character. As his system of thought was not well balanced, leading him to oppose what existed as false and bad, because it was in his way, he left no lasting impression. His Jewish contemporaries persisted in stubborn silence about him, as if they wished his memory to fall into oblivion. He acted like a boy who breaks the windows in an old decaying building, and thus creates a draught. The second seditious thinker of this time, Leo (Judah) ben Isaac Modena (born 1571, died 1649), was of another stamp, and was reared in different surroundings. Leo Modena was descended from a cultivated family which migrated to Modena, in Italy, on the expulsion of the Jews from France, and whose ancestors, from lack of intellectual clearness, despite their education, fostered every kind of superstition and fanciful idea.
