The secret science of the Kabbala, which hitherto had assumed a modest deportment and been of a harmless character, began to foment discord in Ben Adret's time, ensnare the intelligence and lead astray the weak. What it lacked in intrinsic truth and power of conviction, it endeavored to supply by presumptuousness. It had already spread from Gerona, its original seat, and from northern Spain by way of Segovia to southern Spain, as far as the Castilian capital, Toledo, the Jewish community of which had before strenuously opposed obscurantism. In the city of Toledo the Kabbala won the adherence, among others, of one man who, by his noble birth, his princely state, his high position, his wealth and learning, gave it great weight. This man, whose influence is even now not fully recognized, was Todros ben Joseph Halevi, of the noble Toledan family of Abulafia (born 1234, died after 1304). He was a nephew of that Meïr Abulafia who had been so obstinate an adversary of Maimuni and rationalistic thought. Todros Abulafia took as a model his uncle, who in his old age had laid his hands on his head, and blessed him. When he grew up, he applied himself to the Talmud and to secret lore; but he must have been a man of affairs, too, for he obtained an honorable position at the court of Sancho IV, and was in special favor with the wise queen, Maria de Molina, as a physician and financier. By the Jews he was esteemed and venerated as their prince (Nasi). When the king and queen of Spain held a meeting in Bayonne with the king of France, Philip le Bel, to settle their mutual hostilities (1290), Todros Abulafia was in the train of the former, and received the most flattering homage from the Jews of southern France. Todros, like his uncle, was a determined opponent of philosophy and its devotees. He had no words bitter enough against the would-be wise people who hold everything which appears incompatible with logic as incredible and impossible. Even Maimuni, whom he highly respected, he censured for undervaluing the importance of the sacrifices so greatly as to explain them merely as a concession to the heathen propensities of the people, and for calling the offering of incense an expedient for purifying the air. He waged vehement warfare against the philosophy
