Few philosophers have been so mythologised as the 17th century Jew, Baruch Spinoza. Legends abound regarding his life, thought and character. He has … - Benedictus de Spinoza

The supreme mystery of despotism, its prop and stay, is to keep men in a state of deception, and with the specious title of religion to cloak the fear by which they must be held in check, so that they will fight for their servitude as if for salvation.

I think back to the last discussion I had with the great conductor Otto Klemperer. We talked about Spinoza and he said “Spinoza's Ethics is the most important book ever written”. Klemperer was, as we know, Jewish. At the age of 22 he converted to Christianity because he believed that only as a Christian could he conduct Bach's St Matthew Passion. Many years later, after the War, when Klemperer had already reached old age, he converted back to Judaism. And the reason he gave was Spinoza's Ethics. Perhaps the most important Jewish philosophy. Questions about Jewish ethics and morals and “What is being Jewish?” were long identified as being a minority. The traditional thinking and perceived identity of the Jewish people in its 2,000 year history was as a minority. Historically the Jews were integrated into social and cultural life but tragically persecuted under the Spanish Inquisition and the tyranny of Adolf Hitler. What is special about Spinoza's philosophy is that, despite persecution, abuse and alienation, his thinking was never based on the premise of Jews being a minority. That is precisely why his philosophy is so contemporary, now that the Jewish people have their own state, i.e. are no longer a minority. Spinoza's Ethics remains a potent formula for creating intellectual and moral unity among the Jews.

Spinoza's views on God, religion and society have lost none of their relevance. At a time when Americans seem willing to bargain away their freedoms for security, when politicians talk of banning people of a certain faith from our shores, and when religious zealotry exercises greater influence on matters of law and public policy, Spinoza's philosophy – especially his defence of democracy, liberty, secularity and toleration – has never been more timely. In his distress over the deteriorating political situation in the Dutch Republic, and despite the personal danger he faced, Spinoza did not hesitate to boldly defend the radical Enlightenment values that he, along with many of his compatriots, held dear. In Spinoza we can find inspiration for resistance to oppressive authority and a role model for intellectual opposition to those who, through the encouragement of irrational beliefs and the maintenance of ignorance, try to get citizens to act contrary to their own best interests.
