Rabbi Abraham Cohen de Herrera

The Philosophical and Kabbalistic Teaching of Rabbi Abraham Cohen de Herrera: A Synthesis of the Renaissance, Logic and Lurianic Kabbalah

The spiritual world of Rabbi Abraham Cohen de Herrera (also called Alonso Núñez de Herrera or Abraham Irira) constitutes one of the most fascinating intellectual encounters in the history of Jewish thought at the beginning of the modern era. As a figure who embodied in his personality the transition from the life of a converso in Spain and Portugal to the life of a kabbalist and philosopher in the Jewish community of Amsterdam, de Herrera laid the foundation for a veritable revolution in the ways of interpreting Lurianic Kabbalah.^{[1, 2]} His teaching is not merely a local interpretation of the esoteric teaching but a bold and systematic attempt to anchor the fundamental kabbalistic concepts within the philosophical system of Neoplatonism and Renaissance humanism.^{[3, 4]} In his writings, and especially in his monumental work "Sha'ar ha-Shamayim" (Puerta del Cielo), he sought to prove that the Jewish esoteric teaching does not contradict philosophical rationalism, but is itself the ancient and true source on which the greatest philosophers of Greece and Rome relied.^[5]

Chapter 1: The Biographical Journey and the Geography of the Spirit

The life of Abraham Cohen de Herrera spreads across a wide geographical map, reflecting the wanderings of the Spanish-Portuguese diaspora and the vicissitudes of fortune of the conversos who sought to return to their Judaism. He was born around 1570, apparently in Lisbon, Portugal, to a noble converso family (Marrano family).^{[1, 2, 6]} Information about his early years is shrouded in fog, but it is evident that he received a profound humanistic and philosophical education in Italy, apparently in Florence and Venice, where he was exposed to the thought of the Florentine Academy and to Marsilio Ficino's translations of the writings of Plato and Plotinus.^{[1, 7]}

During the 1590s, de Herrera acted on behalf of his uncle, Yehuda de Marchena, who served as a commercial agent for the Moroccan sultan Moulay Ahmad al-Mansur.^{[1, 2, 8]} A dramatic turn in his life occurred in 1596, when he was staying in the city of Cádiz on the sultan's mission; during the capture of the city by the English fleet, de Herrera was taken captive and transferred to London.^{[1, 6, 8]} His release was obtained only in 1600, after a vigorous exchange of diplomatic letters between the Moroccan sultan and Queen Elizabeth I, an event that attests to de Herrera's high political and economic standing at that time.^{[2, 6]}

After his release, de Herrera began an accelerated process of open return to Judaism. He settled in Ragusa (today's Dubrovnik), where he met Rabbi Israel Sarug, one of the most prominent and influential disciples of the Ari.^{[1, 2, 8]} The encounter with Sarug was decisive; Sarug disseminated a version of Lurianic Kabbalah that was organized in a rigid logical structure and included philosophical elements that did not appear in the writings of Rabbi Chaim Vital.^{[7, 9]} Under Sarug's guidance, de Herrera became a kabbalist in the full sense, while using his earlier philosophical tools to understand the new cosmological structures of the Ari.^{[3, 7]} Finally de Herrera moved to Amsterdam, where he joined the Sephardic congregation "Talmud Torah" and became one of its most influential thinkers until his death in 1635 (or 1639).^{[2, 6, 10]}

Chapter 2: The Corpus of Writings and the Language of Composition as a Pedagogical Tool

De Herrera's uniqueness among the kabbalists is expressed first and foremost in his choice to write his principal works in Spanish. This decision did not stem merely from a lack of full command of Hebrew, but was the fruit of deliberate pedagogical planning intended to serve the community of conversos returning to Judaism in Amsterdam.^{[11, 12]} These conversos, who were educated in European culture and had mastered the secrets of general philosophy, found it difficult to digest the kabbalistic myths in their original version; de Herrera sought to give them an intellectual "key" that would enable them to embrace the Jewish tradition without renouncing their rational education.^{[12, 13]}

The Principal Works

Puerta del Cielo (Gate of Heaven): his most important and comprehensive work, dealing with the doctrine of the Godhead, the Ein Sof (the Infinite), emanation and cosmology.^{[1, 2]} It is a systematic attempt to present Lurianic Kabbalah as a coherent metaphysical system that corresponds with Neoplatonism.^{[3, 14]} The work is divided into ten books, the last of which is devoted to proofs of the existence of a First Cause.^[5]

Casa de Dios / Casa de la Divinidad (House of God): a work devoted mainly to the doctrine of angels (angelology), the structure of the spiritual worlds and mystical psychology.^{[1, 2, 3]} Here de Herrera examines the relations between the soul and the higher powers through a philosophical-religious prism.^{[3, 4]}

Epitome y compendio de la lógica o dialéctica (Epitome of Logic): this is his only book printed in his lifetime. It is a manual of Aristotelian logic and dialectic, including a dictionary of philosophical terms (Libro de Diffinitiones).^{[2, 13, 15]} The book was intended to serve as a methodical introduction for the beginning kabbalist, on the assumption that only one who masters the laws of thought can understand the secrets of Kabbalah.^{[12, 13]}

After his death, "Sha'ar ha-Shamayim" and "Beit Elohim" were translated into Hebrew by his disciple, Rabbi Isaac Aboab da Fonseca, and published in Amsterdam in 1655.^{[6, 7, 11]} These translations were not literal translations but free adaptations (Adaptations), which adapted the text to a Hebrew-speaking audience but also omitted some of the direct references to Christian and pagan philosophers.^[7] The Hebrew edition enjoyed wide circulation and became the source through which kabbalists of later generations came to know de Herrera's teaching.^{[2, 11]}

Chapter 3: The Synthesis between Kabbalah and Neoplatonic Philosophy

De Herrera is considered the first kabbalist to establish a methodical and comprehensive philosophical system for the esoteric teaching. At the heart of his teaching stands the assumption that Kabbalah is the Prisca Theologia, the ancient and true "theology" that was given to Moses at Sinai and passed down in the oral tradition until it was corrupted or partially adopted by philosophers such as Plato.^{[5, 13]} In his view, these are not two separate fields but two layers of the same truth, with philosophy serving as the intellectual vessel for understanding the metaphysical secrets.^{[3, 12]}

He drew deep inspiration from the Neoplatonism of the Renaissance, and especially from the thought of Marsilio Ficino and Giovanni Pico della Mirandola.^{[2, 14, 15]} Pico della Mirandola, whom de Herrera called "the phoenix of his time," was an exemplary figure for him as one who had succeeded in finding the connection between Jewish Kabbalah and Christian and classical thought.^[7] In his work "Sha'ar ha-Shamayim," de Herrera cites and interprets entire passages from Pico's writings (such as the Commento), showing how they accord with the words of the Ari.^[7]

The use of philosophical tools enabled de Herrera to "normalize" the Lurianic myth. Whereas classical Lurianic Kabbalah abounds in anthropomorphic descriptions (personification) and in mythical images of breaking and repair, de Herrera translated these concepts into terms of being, causality, ideas and Neoplatonic emanation.^{[2, 8]} In this way he turned Kabbalah from a closed mythical doctrine into a system of thought open to dialogue with Western philosophy.^{[3, 4, 13]}

Chapter 4: The Doctrine of the Godhead and the Ein Sof (Ensoph)

One of de Herrera's central contributions is his redefinition of the concept of the "Ein Sof" (Ensoph). He defines the Ein Sof as the "First Cause" and as "Necessary Being," a distinctly scholastic term describing an entity whose existence derives from its own essence and does not depend on anything.^{[2, 3, 5]} For him the Ein Sof is absolute perfection, exalted above all human or angelic comprehension, and it is not defined by any positive attribute but by way of negation (Negative Theology).^[2]

Nevertheless, de Herrera incorporates into his definition of the Godhead the dialectical concept of Coincidentia Oppositorum, the "unity of opposites."^[2] In the Ein Sof all the opposites exist in one simple point; it is both everything and nothing, both the source of all multiplicity and absolute unity. This conception enabled him to bridge between the remote transcendent God of philosophy and the providential and involved God of the kabbalistic tradition.^[5]

The Relation between the Ein Sof and the Worlds

De Herrera stresses that although the Ein Sof contains within itself all of reality in an exalted and infinite form, it must not be identified with the sum total of empirical reality (this world). In this way he seeks to prevent a simple pantheistic interpretation that might lead to a denial of God's transcendence.^[2] He uses the metaphor of "light" and of "infinite expansion" (Hitpashetut) to explain how the divine abundance bursts forth from the source without diminishing it, like the light of the sun that illuminates the world without the sun changing.^[2]

Chapter 5: The Doctrine of Metaphorical Tzimtzum: A Revolution in Lurianic Interpretation

The doctrine of "tzimtzum" (Tzimtzum) is the cornerstone of Lurianic Kabbalah. According to the Ari, in order to create the finite world, the Ein Sof had to "contract" itself and clear a space (a vacated space) in which reality would become possible. De Herrera, in the spirit of his philosophical teaching, was one of the most prominent and earliest representatives of the approach holding that "the tzimtzum is not literal."^[11]

According to his interpretation, no real change or motion is possible within the infinite Godhead, since that would be a flaw in its perfection. Therefore the tzimtzum is not a physical withdrawal of the divine light but a volitional and metaphorical act intended to adapt the divine abundance to the capacity of finite creatures to receive it.^{[2, 3, 4]} The tzimtzum is in fact a "concealment" (Occultation) of the light, which allows the creatures to sense themselves as separate entities without being nullified in the infinite source.^[11]

This position, which came to be called "tzimtzum she-lo ki-feshuto" (non-literal tzimtzum), was essential for de Herrera in order to defend Kabbalah against accusations of corporealism and of ascribing changes to God. Over the years it became the accepted position in wide parts of the kabbalistic world, and especially within the Hasidic movement and Chabad thought.^[11]

Chapter 6: Adam Kadmon and the Cosmic Logos

The concept of "Adam Kadmon" (Primordial Man) occupies a central place in de Herrera's cosmology. He identifies Adam Kadmon with the Neoplatonic "Intelligible World" and sees in it the "First Effect" (Primum Principium / First Effect) proceeding from the First Cause.^{[2, 3, 4]}

Unlike the Ein Sof, which is entirely undefined, Adam Kadmon is the beginning of multiplicity and structure. De Herrera describes it as the "supreme thought" or the "simple intelligence" that contains within it the archetypes (Archetypes) of everything that is to be created.^[2] This is the kabbalistic "Logos," the shaping and organizing principle of reality, based on the structure of the number four (the Tetragrammaton, the name Havayah) in accordance with the Pythagorean tradition.^{[3, 4, 5]}

Adam Kadmon constitutes the link connecting the absolute and the limited. Despite its immense perfection, de Herrera stresses that it is "finite" (Finite) relative to the Ein Sof, since it is emanated and has a beginning, unlike God, who is eternal and uncreated.^[2] This distinction is essential in order to preserve the ontological gap between the Creator and the created.

Chapter 7: De Herrera's Influence on Baruch Spinoza

The connection between de Herrera and Baruch Spinoza is one of the most fascinating and most researched topics in modern thought. Spinoza, who grew up in the Amsterdam community and studied in its institutions, was undoubtedly exposed to the writings of de Herrera, which formed an inseparable part of the community's intellectual atmosphere at that time.^{[10, 16]}

Many scholars, foremost among them Miguel Beltrán, point out that many of the central themes of Spinoza's "Ethics" were foreshadowed in de Herrera's "Sha'ar ha-Shamayim."^{[16, 17]}

Metaphysical Points of Similarity

• God as infinite substance: Spinoza's conception of God as a single and infinite Substantia (substance) with infinitely many attributes closely parallels de Herrera's definition of the Ein Sof as a First Cause that contains all beings in an exalted form.^{[16, 17]}
• Immanent causality: the Spinozist concept of Causa Sui ("cause of itself") appears in de Herrera as part of the definition of the Ein Sof as a necessary being whose nature is to exist.^{[16, 17]}
• Acosmism and panentheism: both share the conception according to which reality does not exist "outside" God but within Him (Panentheism). This view leads to some extent to acosmism, the conception that the finite world in itself is a kind of illusion or a partial perspective of the true divine reality.^{[16, 17]}
• The geometrical method: scholars point out that de Herrera's dialectical and systematic style of writing, especially in the use of logical propositions and proofs at the end of "Sha'ar ha-Shamayim," may have served as a model for Spinoza's famous "geometrical order."^{[10, 16]}
• Biblical criticism: de Herrera, in his attempt to give a rational interpretation to the kabbalistic and biblical sources, anticipated in certain respects Spinoza's critical-rationalist approach to religious tradition.^{[10, 16]}

There is a fascinating scholarly hypothesis according to which the ban (cherem) on Spinoza in 1656 did not stem merely from outright heresy, but perhaps precisely from an overly radical and "pantheistic" interpretation of the writings of de Herrera, which were still considered to be within the bounds of orthodox Kabbalah.^[16]

Chapter 8: Dissemination in Europe: Leibniz, Henry More and the Kabbala Denudata

De Herrera's teaching broke through the boundaries of the Jewish community and reached the great minds of European thought in the 17th and 18th centuries. The main channel of transmission was the book Kabbala Denudata (Kabbalah Unveiled), a Latin anthology edited by Christian Knorr von Rosenroth.^{[2, 7, 18]} Von Rosenroth included in his book Latin translations of extensive parts of "Sha'ar ha-Shamayim" and "Beit Elohim" (under the titles Porta Caelorum and Pneumatica Cabbalistica), and thereby made de Herrera the most authoritative source for the Christian world for understanding Kabbalah.^[7]

Gottfried Wilhelm Leibniz, one of the most important philosophers and mathematicians in history, kept de Herrera's writings in his library and engaged with them extensively.^{[7, 14, 15]} Leibniz found particular interest in the description of the angels and the spiritual levels in "Beit Elohim," something that echoed to some extent in his theory of "monads." The English philosopher Anne Conway was also deeply influenced by de Herrera's description of the tzimtzum in her interpretation of the process of creation as a diminution of the divine light.^[8]

The thinker Johann Georg Wachter (Johan Georg Wachter) even claimed in 1699 that it was de Herrera who gave Spinoza the seeds of his pantheistic "heresy," a claim that aroused a broad controversy around the question of the connection between Jewish mysticism and modern philosophy.^{[3, 4]}

Chapter 9: Controversies and Rabbinic Kabbalah: Reception and Opposition

Despite its distinctly philosophical character, de Herrera's teaching was deeply integrated into the world of rabbinic Kabbalah, though not without storms.

Supporters and Successors

• Rabbi Yosef Ergas (1685–1730): in his famous work "Shomer Emunim," Ergas defends with great devotion de Herrera's position regarding non-literal tzimtzum. Ergas used philosophical tools similar to those of de Herrera to prove that the Godhead does not change, and this position became a permanent asset of Italian and Sephardic Kabbalah.^[11]
• Rabbi Moshe Chaim Luzzatto (the Ramchal): de Herrera's influence is clearly evident in the systematic structure of the Ramchal. The Ramchal, who also sought to give a logical and rational explanation of Kabbalah, adopted many of de Herrera's methods in organizing the teaching of the Ari.^[11]
• Hasidism and the Chabad movement: de Herrera is considered one of the important sources for the doctrine of "non-literal tzimtzum" in Hasidism. Rabbi Shneur Zalman of Liadi, the founder of Chabad, based part of his doctrine of unity on these principles. His grandson, the "Tzemach Tzedek," mentions de Herrera in his writings with great esteem.^[11]
• Rav Kook (the Ra'ayah): Rav Kook cites de Herrera in his letters (for example, letter 926), linking his cosmological distinctions in "Sha'ar ha-Shamayim" with halakhic and spiritual concepts of holiness.^[11]

Opponents and Critics

On the other hand, there were kabbalists who saw in de Herrera's way a dangerous deviation from the pure tradition. Rabbi Tzadok ha-Kohen of Lublin, one of the great figures of later Hasidic thought, spoke out sharply against studying de Herrera's books. In his view, de Herrera confronted the words of the Ari with "the reasoning of his own heart" and with the words of pagan philosophers, something that harms the prophetic and divine character of Kabbalah.^[11] The Sabbatean controversy also cast a shadow over de Herrera's name, when the Sabbatean kabbalist Abraham Miguel Cardoso adopted many of his conceptions in order to establish the Sabbatean theology of the "mystery of the Godhead," which aroused suspicion toward the original writings among conservative circles.^[11]

Chapter 10: Modern Research and Critical Editions

In the last hundred years de Herrera has attracted enormous scholarly interest, not only as a historical figure but as a key to understanding the transition from the Middle Ages to modernity in Judaism. Gershom Scholem, the father of Kabbalah research, devoted extensive space to him in his studies and pointed to him as a key figure in the spread of Lurianic Kabbalah in Western Europe.^{[9, 19]}

In 2002 a scholarly annotated Hebrew edition of "Sha'ar ha-Shamayim" was published by Nissim Yosha (Ben-Zvi Institute).^{[11, 20, 21]} This edition, translated directly from the original Spanish writings (unlike Aboab's translation), revealed anew the wealth of de Herrera's sources. The work is studded with references to the writings of Plato (Timaeus, Parmenides, Phaedo), Aristotle, Plotinus (Enneads), Proclus (Elements of Theology), and Renaissance philosophers such as Ficino, Patrizi and Pico della Mirandola.^{[2, 5, 7, 13]}

Summary and Conclusions

Rabbi Abraham Cohen de Herrera stands as an intellectual bridge between worlds that seem at first glance to be opposed: intricate Lurianic mysticism on the one hand, and Neoplatonic and scholastic rationalism on the other. His achievement lies not merely in the attempt to "translate" one language into another, but in the creation of a deep synthesis offering a religious worldview that does not give up the dignity of the human intellect.

Through his interpretation of the tzimtzum, his definition of the Ein Sof as a First Cause and his presentation of the figure of Adam Kadmon as a cosmic Logos, he gave Kabbalah tools of survival in the approaching age of Enlightenment. His influence on Baruch Spinoza and Gottfried Leibniz makes him one of the Jewish thinkers who most influenced the shaping of modern Western philosophy. For the world of Torah, de Herrera remains the highest model of the "kabbalist-philosopher," a figure who reminds us that the secrets of the Torah and pure reason may spring from the same supreme source. His teaching continues to resonate to this day wherever the depth of mystical thought meets the clarity of philosophical analysis.
