Prologue: Baruch, Bento,  Benedictus    By what right is Benedictus Spinoza included in this series, devoted as   it is to Jewish themes and thinkers?
    Can the seventeenth-century rationalist, who produced one of the most   ambitious philosophical systems in the history of Western philosophy,   be considered, by any stretch of interpretation, a Jewish thinker? Can   he even be considered a Jew? Benedictus Spinoza is the greatest   philosopher that the Jews ever produced, which adds a certain irony to   his questionable Jewishness.
    He was excommunicated at the age of twenty-three by the   Portuguese-Jewish community in which he had been raised and educated.   It was a community of refugees from the Spanish-Portuguese Inquisition,   a Jewish calamity whose tragic proportions would be exceeded only in   the twentieth century. The members of the community were predominantly   former Marranos, who had lived on the Iberian Peninsula, mostly in   Portugal, as practicing Christians since Judaism had been formally   outlawed on the peninsula at the end of the fifteenth century. The word   marrano is believed to derive from the old Castilian for “swine,” a   particularly apt slur to insult those believed to be concealing Jewish   practice beneath Christian performance. The relatively liberal city of   Amsterdam provided the conditions for their reconnecting to a Judaism   that most of them barely knew. Brutal forces of history had given this   community its distinctive tone: ambitious for the material trappings of   middle-class stability and yet skittish, anxious; enviably accomplished   and cosmopolitan and yet filled with religious intensity, confusion,   disillusion, and messianic yearning.
    Before his expulsion from it, the hothouse world of Amsterdam’s   Sephardim—as Jews who derived from Spain (Sepharad in Hebrew) continue   to be called to this day—had been Spinoza’s world as well. Yet when it   closed its doors to him, he made no attempt to reenter it or any other   Jewish community.
    Excommunication, as it was practiced in his community, was not as   severe and final a punishment as the word now suggests. The period of   isolation from the community (the terms of excommunication did not   extend outside of Amsterdam) typically lasted anywhere from a day to   several years. The imposed banishment was a tool of chastisement   resorted to with quite common frequency, fundamentally a form of public   embarrassment with which to exert control over the volatile mix   contained within “the Portuguese Nation,” as the Amsterdam Sephardim   continued to identify themselves.
    Whereas others among the chastised had obediently—and sometimes   desperately—sought reconciliation, Spinoza calmly removed himself from   any further form of Jewish life. Nor did Spinoza seek out another   religion. In particular, he did not convert to Christianity, though it   would have been convenient for him to do so. Spinoza opted for   secularism at a time when the concept had not yet been formulated.
    He supported himself by grinding lenses, which was no lowly menial   occupation, as it is often presented to have been in romanticizing   versions of the philosopher’s life, but was rather a craft that drew   extensively from Spinoza’s serious interest in the science of optics.   The quality of his wares was highly valued by other scientists of his   day. The important Dutch astronomer Christiaan Huygens, who discovered   Saturn’s rings as well as one of its four moons, preferred Spinoza’s   lenses to all others. “The [lenses] that the Jew of Voorburg has in his   microscopes have an admirable polish,” Huygens wrote to his brother in   1667. The one part of the romantic lens-grinding legend that is sadly   true is that the dust from the optical polishing was unhealthy for   Spinoza, whose mother and brother had both died young from   tuberculosis. He himself succumbed to the disease at the age of   forty-four.
    Spinoza’s personal life was, as he wished it to be, simple and   relatively isolated. There was a small circle of devoted friends,   freethinking Christians from various dissenting Protestant circles, who   regarded Spinoza as their master and closely studied, and guarded, his   thoughts. He combined a Marranoist cautious discretion about revealing   his true views to the dangerously narrow-minded with a touching faith   in the power of reason to persuade. So he published his Tractatus   Theologico-Politicus (The Treatise on Theology and Politics)   anonymously, but also hoped that it would convince the powers that be   of its main conclusion, which is succinctly stated in the book’s   subtitle: Wherein is set forth that freedom of thought and speech not   only may, without prejudice to piety and the public peace, be granted;   but also may not, without danger to piety and the public peace, be   withheld. The book evolves into one of the most impassioned defenses of   a free democratic state in the history of political theory, an eloquent   plea for the separation of church and state. Spinoza allowed himself to   hope that, should its argument for tolerance find its mark, he might be   able to publish the work on which he had been toiling for years. The   rain of abuse that poured down on the author of the Tractatus, whose   true identity was soon an open secret throughout Europe, made him a   very dangerous man to even remotely acknowledge, and all but foreclosed   the possibility of his publishing his magnum opus in his lifetime. This   is The Ethics, a work that makes all the claims for reason that have   ever been made.
    Some favors came his way. The University of Heidelberg, which had   fallen from its perch of previous glory through the prolonged   tribulations of the Thirty Years’ War, had no professor of philosophy   on staff and, in the name of Karl Ludwig, Elector Palatine, offered him   a chair of philosophy. “You will not find elsewhere a Prince more   favorably disposed to men of exceptional genius, among whom he ranks   you. You will have the most extensive freedom in philosophizing, which   he believes you will not misuse to disturb the publicly established   religion.” The philosopher delicately declined: “If I had ever had any   desire to undertake a professorship in any faculty, I could have wished   for none other than that which is offered me through you by the Serene   Highness the Elector Palatine, especially on account of the freedom to   philosophize that this most gracious Prince is pleased to grant, not to   mention my long-felt wish to live under the rule of a Prince whose   wisdom is universally admired.” But his instinct for caution had been   alerted by the ambiguity of the terms of the offered freedom. “I do not   know within what limits the freedom to philosophize must be confined if   I am to avoid appearing to disturb the publicly established religion. .   . . So you see, most Honorable Sir, that my reluctance is not due to   the hope of some better fortune, but to my love of peace, which I   believe I can enjoy in some measure if I refrain from lecturing in   public.”
    Some important intellectual figures of the day made their way to the   modest rooms he rented in the Hague in his last years, including the   up-and-coming young go-getter Gottfried Wilhelm Leibniz, who would   emerge as one of the most dazzling figures in the seventeenth century’s   impressive lineup of genius. Leibniz spent a few days with Spinoza,   conversing on metaphysics. The only written record of their extensive   conversations was a slip of paper on which Leibniz had written down,   for Spinoza’s approval, a proof for God’s existence. Leibniz was   profoundly influenced by Spinoza’s ideas but sought always to conceal   his philosophical debt, and is on record as denouncing the philosopher.   When a professor of rhetoric at the University of Utrecht, one Johan   Georg Graevius, wrote to Leibniz, castigating the Tractatus   Theologico-Politicus as a “most pestilential book,” whose author “is   said to be a Jew named Spinoza, but who was cast out of the synagogue   because of his monstrous opinions,” Leibniz prudently chimed in with   his own diplomatic calumny: “I have read the book by Spinoza. I am   saddened by the fact that such a learned man has, as it seems, sunk so   low.”
    Spinoza remained throughout his life, and well into the eighteenth   century, a thinker whom one could admire only in secret, hiding one’s   sympathy just as his Marrano antecedents had concealed their wayward   Jewishness. Open admiration could destroy even the most established of   reputations, well into the eighteenth century’s so-called Age of   Reason. In the 1780s, for example, Friedrich Heinrich Jacobi launched a   generalized attack on Enlightenment thought by claiming that the late   poet Lessing had been a closet Spinozist, a charge sufficient to   compromise the entire movement for which Lessing had been a leading   spokesman. Jacobi even went after Immanuel Kant and his successors,   arguing that “consistent philosophy is Spinozist, hence pantheist,   fatalist, and atheist.”
    The holy furor aroused by the name Spinoza is in contrast to the man’s   predilection for peace and quiet. He confessed himself to have a horror   of controversy. “I absolutely dread quarrels,” he wrote an   acquaintance, explaining why he had declined to publish a work that   contains some of the main themes of The Ethics, titled Short Treatise   on God, Man, and His Well-Being. The signet ring he wore throughout   his life was inscribed with the word caute, Latin for “cautiously,” and   it was engraved with the image of a thorny rose, so that he signed his   name sub rosa. One might argue that the very form of The Ethics,   written in the highly formalized “geometrical style” inspired by   Euclid’s Elements, is partially designed for the practical purpose of   keeping out any but the most gifted of readers, rigorously cerebral and   patiently rational.
    Spinoza’s ambitions on behalf of reason are staggering: he aims to give   us a rigorously proved view of reality, which view will yield us, if   only we will assimilate it, a life worth living. It will transform our   emotional substance, our very selves. The truth shall set us free. His   methodology for exposing the nature of reality was inspired by one of   the strands that the seventeenth century’s men of science were weaving   into what we now refer to as the scientific method, that magnificently   subtle, supple, and successful blend of mathematical deduction and   empirical induction. Spinoza was keenly interested, and involved in the   intellectual innovations that we now look back on as constituting the   birth of modern science. His inspiration came from the mathematical   component of modern science, not its empiricism. The methodology he   believed could reveal it all was strictly deductive, which is not the   way that science ultimately went. (Still, there are contemporary   physicists and cosmologists who are inspired by the Spinozist ideal of   “a theory of everything,” one in which the mathematics alone would   determine its truth. String theorists, in particular, pursue physics   almost entirely as a deductive endeavor, letting their mathematics   prevail over niggling empirical questions. The spirit motivating them   is Spinozism, which sometimes makes other scientists question whether   what string theorists are up to really qualifies as science at all.)
    But if the claims Spinoza makes on behalf of pure reason can strike us   as staggering, there are also, staggeringly, a number of propositions   that he produced from out of his deductive system that have been,   centuries later, scientifically vindicated. A leading neurobiologist,   Antonio Damasio, argues in his Looking for Spinoza: Joy, Sorrow, and   the Feeling Brain that Spinoza’s view of the relationship between mind   and brain, as well as the complicated theory of the emotions that he   deduced from it, are precisely what the latest empirical findings   support. Spinoza, despite his nonempiricist methodology, is not   scientifically irrelevant.
    But there are claims that come out of Spinoza’s deductive system that   are even more important for our times, more piercingly relevant, than   his happening to have produced a stunningly contemporary answer,   through pure deductive reason, to the mind-body problem and given us a   view of the emotions that science has caught up with, in thinkers like   Damasio, after some three hundred years. What Spinoza has to say about   the importance of allowing the discovery of nature to proceed unimpeded   by religious dogma could not speak more pertinently to some of the   raging controversies of our day, including the recurring public debate   in America over Darwin’s theory of evolution. The sides are drawn up   now much as they were in Spinoza’s own day.
    Just as relevant to current concerns, particularly in America, is his   fundamental insistence on the separation of church and state. John   Locke, who spent some years in Amsterdam, right after Spinoza’s death,   associating with thinkers who had known and been influenced by Spinoza,   transmitted this insistence to the founding fathers of America. The   spirit of Spinoza lives on in the opening words of the First Amendment   to the U.S. Constitution, the phrase referred to as the Establishment   clause: “Congress shall make no law respecting an establishment of   religion.”
    Spinoza placed all his faith in the powers of reason, his own and ours.   He enjoins us to join him in the religion of reason, and promises us   some of the same benefits—while firmly denying us others—that   traditional religions promise. Rigorous reason will lead us to a state   of mind that is the height of what we can achieve not only   intellectually but also, in a sense—the only sense compatible with his   rationalism—spiritually. The aim of his ethics is to give us the means   to arrive at a “contentment of spirit, which arises out of the . . .   knowledge of God.” This is the state of mind dubbed “blessedness” by   the man who had been known in three different languages—Hebrew,   Portuguese, and Latin—by a name that translates into “blessed”: Baruch,   Bento, and Benedictus.
    It is hard for us to appreciate the loneliness of Spinoza’s secularized   spirituality. For an individual of the early seventeenth century to   live outside the bounds of a religious
    identity—to aim to be perceived as neither Jew, nor Christian, nor   Moslem—was all but unthinkable; and, in fact, Spinoza did continue to   be called, with predictable disdain, a Jew. Huygens, for example, never   refers to Spinoza by name in his letters, even though the two often   conversed on such fields of mutual interest as mathematics and optics;   but rather Spinoza is always “the Jew of Voorburg” or, even more   belittlingly, “our Israelite,” “our Jew.”
    The social frame of reference enclosing every individual of the   premodern era was inherently religious. Spinoza’s choice was an   instance of a principle that had yet to be discerned in even the   vaguest outline. Part of the horror he invoked throughout Europe   derived from the radical stance he assumed simply by pursuing a life   with no religious affiliation. Though the Romantic poet Novalis called   him, and for good reason, “God-intoxicated,” he was also routinely   excoriated as an atheist. He seemed to have been genuinely dismayed by   the charge, though his conception of God is sufficiently peculiar—and   subtle—that one can see how his constant talk of God might strike even   us today as disingenuous, yet another old Marranoist trick of hiding   one’s unacceptable beliefs under formulaic insincerities.
