Spinoza famously equated God and Nature. Most people take this to be a thoroughly materialist position, but this means ignoring Spinoza’s frequent and insistent distinctions between matter and thought. In the early twentieth century, two proponents of Spinoza, Constantin Brunner and Harry Waton, attempted to set the record straight. In doing so, they revealed Spinoza’s god as the basis of the real itself.
As Max Dimont puts it:
Constantin Brunner’s book, Our Christ: The Revolt of the mystical genius, contains a significant passage wherein the god of Spinoza is identified with the idea at the root of the Biblical Jahve:
Harry Waton develops this theme:
In the work of these two great teachers we find the foundation of a truly rational spirituality that provides the way forward for mankind and science.
As Max Dimont puts it:
The nineteenth-century Jewish Enlightenment was like a beam of light refracted through a prism into a spectral band of brilliant intellectual colors spread across Western Europe. The prism through which Jewish thought was refracted was a Jew born in Amsterdam in 1632, a Jew so modern in his thinking that the second half of the twentieth century has not yet caught up with him. Excommunicated by the Jews in the seventeenth century, abhorred by the Christians in the eighteenth century, acknowledged great in the nineteenth century, Baruch Spinoza will perhaps not be fully understood even in the twenty-first century. But perhaps by then Spinoza's philosophy will have become the basis of a world religion for neomodern man.
Constantin Brunner’s book, Our Christ: The Revolt of the mystical genius, contains a significant passage wherein the god of Spinoza is identified with the idea at the root of the Biblical Jahve:
Jahveh ehad, cried Moses: "Hear O Israel, Being is our God, Being is One" (Deut. 6:4).
Yet this quotation provides precisely the historically monstrous example of how Israel hears and how the truth is straightway transformed into superstition in Israel's ears. For this magnificent saying is at once a hymn of exultation and a wrathful protest against idol worship of any kind; but despite this protest, it now signifies—in the conception of Israel, the Jewish, Christian and Muslim Israel—the well-enough known, imbecilically wrong translation: "Hear O Israel, the Lord our god is the only God!" (Brunner, Spinoza gegen Kant, page 43). Moses said that thou shalt not make unto thee any image of this Jahveh, no imagination of it, i.e., it is that which cannot be thought as things are thought, as if it had the same sort of being as things—I am that I am (Ex. 3:14)! Jahveh, Being, is the term for the wholly abstract spiritual; it has no relation to the relative world. By Jahveh, the wholly great is meant. It means the same thing as Spinoza does in his great—his absolutely great expression, Ens constans infinitis attributis (Absolute Being with infinite attributes.) And Jahveh Tsebaot, Jahveh of infinite powers, is nothing but the mystical expression of the same thing as is expressed philosophically by Ens constans infinitis attributis. The whole tremendous concern of Judaism lies in this phrase Jahveh ehad [Ehad=one and only. Pronunciation; with a gutteral 'kh', accent on the second syllable], in that single word Jahveh, which was ultimately forbidden even to be pronounced, and to pronounce which was a deadly sin. The mystical primordial character of Judaism—so naturally mystical that the Jews, in spite of their having made Jahvism into religion, never established a mythology, even while their Jahveh always remained exalted as God over every god of other religions, so that other ancient civilizations did not recognize him as a god, and said the Jews were without religion and atheistic—the mystical primordial character of Judaism expressed itself in this, its ineffable holy word.
Harry Waton develops this theme:
In a grain of sand God is as absolute, infinite and eternal as in the whole infinite and eternal existence. But the realities of existence are implicit, that is, they are not conscious of God. Only man is destined to attain to explicitness, that is, the consciousness of God. Man attains to this consciousness of God when he attains to the intellect. The intellect is the soul wholly explicit. The soul becomes conscious of God, the soul perceives that she is part of God. The soul then identifies herself with God, and then attains to what Spinoza calls the intellectual love of God. When man attains to the intellect, he then perceives that he is the I am I of God; that is, God sees himself in man as the I am I, and man sees himself in God as the I am I of God. Then man and God are one, not only in essence, but also in consciousness and understanding. This is the highest state that man can attain. This profound idea was expressed in the Shemah— the holiest sentence in the Bible and in Judaism. The Shemah tells us: Hear, O Israel, Jehovah our God Jehovah is one! Here the name Jehovah is mentioned twice. What does this mean? This expresses the profound truth. The second Jehovah is man— the man that attained to the intellect and who perceives that he is the I am I of Jehovah. This sentence tells us that Jehovah our God and Jehovah the man of intellect is one. This is the deepest and highest truth that mankind attained and will ever attain. Thus we see that Moses and the Prophets already attained to the deepest and the highest idea — there will never be a deeper and higher idea revealed to man.
In the work of these two great teachers we find the foundation of a truly rational spirituality that provides the way forward for mankind and science.
