save freedom of thought and free expression of opinion. Every man has this right by nature, the only one which he has not transferred to the state, because it is essentially inalienable. It must be conceded to everyone to think and judge in opposition to the opinion of the government, even to speak and teach, provided this be done with reason and reflection, without fraud, anger, or malice, and without the intention of causing a revolution. On this weak basis, supported by a few other secondary considerations, Spinoza justified his conflict with Judaism and his philosophical attacks upon the sacred writings recognized by the Dutch States. He thought that he had succeeded in justifying himself before the magistrates sufficiently by his defense of freedom of thought. In the formulation of this apology it was apparent that he was not indifferent to the treatment which he had experienced from the college of rabbis. Spinoza was so filled with displeasure, if not with hatred, of Jews and Judaism, that his otherwise clear judgment was biased. He, like Da Costa, called the rabbis nothing but Pharisees, and imputed to them ambitious and degraded motives, while they wished only to secure their treasured beliefs against attacks. Prouder even than his contemporaries, the French and English philosophers, of freedom of thought, for centuries repressed by the church, and now soaring aloft the more powerfully, Spinoza summoned theology, in particular, ancient Judaism before the throne of reason, examined its dogmas and archives, and pronounced sentence of condemnation upon his mother-faith. He had erected a tower of thought in his brain from which, as it were, he wished to storm heaven. Spinoza's philosophy is like a fine net, laid before our eyes, mesh by mesh, by which the human understanding is unexpectedly ensnared, so that half voluntarily, half compulsorily, it surrenders. Spinoza recognized, as no thinker before, those universal laws, immutable as iron, which are apparent in the development of the most insignificant grain of seed no less than in the revolution of the heavenly bodies, in the precision of mathematical thought as in the apparent irregularity of human passions. Whilst these laws work with constant uniformity, and produce the same causes and the same phenomena in endless succession, the instruments of law are perishable things, creatures of a day, which rise, and vanish to give place to others: here eternity, there temporality; on the one side necessity, on the other chance; here reality, there delusive appearances. These and other enigmas Spinoza sought to solve with the penetration that betrays the son of the Talmud, and with logical consecutiveness and masterly arrangement, for which Aristotle might have envied him.
