The Berlin of the day – the day of Frederick the Great – was in a moral and intellectual ferment. Lessing had recently produced the drama Die Juden, whose moral was that a Jew can possess nobility of character. This notion was then generally ridiculed as untrue. Lessing found in Mendelssohn the realization of his dream. Within a few months of the same age, the two became brothers in intellectual and artistic camaraderie. Lessing also brought Mendelssohn to public attention for the first time: Mendelssohn had written an essay attacking Germans' neglect of their native philosophers (principally Gottfried Leibniz

), and lent the manuscript to Lessing. Without consulting the author, Lessing published Mendelssohn's Philosophical Conversations (Philosophische Gespräche) anonymously in 1755. In the same year there appeared in Danzig (Gdańsk) an anonymous satire, Pope a Metaphysician (Pope ein Metaphysiker), which turned out to be the joint work of Lessing and Mendelssohn.

Early prominence as philosopher and critic


Mendelssohn became (1756–1759) the leading spirit of Friedrich Nicolai's important literary undertakings, the Bibliothek and the Literaturbriefe, and ran some risk (which Frederick's good nature mitigated) by criticizing the poems of the King of Prussia. In 1762 he married Fromet Guggenheim, who survived him by twenty-six years. In the year following his marriage Mendelssohn won the prize offered by the Berlin Academy for an essay on the application of mathematical proofs to metaphysics, On Evidence in the Metaphysical Sciences; among the competitors were Thomas Abbt

They insisted on Mendelssohn telling them his views on Jesus and managed to get from him the statement, that, provided the historical Jesus had kept himself and his theology strictly within limits of orthodox Judaism, Mendelssohn "respected the morality of Jesus' character". Six years later, in October 1769, Lavater sent Mendelssohn his German translation of Charles Bonnet

When, in 1775 the Swiss-German Jews, faced with the threat of expulsion, turned to Mendelssohn and asked him to intervene on their behalf with "his friend" Lavater, Lavater, after receiving Mendelssohn's letter, promptly and effectively secured their stay.

Illness


In March 1771 Mendelssohn's health deteriorated so badly that Marcus Elieser Bloch

, his doctor, decided his patient had to give up philosophy, at least temporarily. After a short and restless sleep one evening, Mendelssohn found himself incapable of moving and had the feeling of something lashing his neck with fiery rods, his heart was palpitating and he was in an extreme anxiety, yet fully conscious. This spell was then broken suddenly by some external stimulation. Attacks of this kind recurred. The cause of his disease was ascribed to the mental stress due to his theological controversy with Lavater. However, this sort of attack, in milder form, had presumably occurred many years earlier. Bloch diagnosed the disease as due to 'congestion of blood in the brain' (a meaningless diagnosis in modern medical practice as such congestion is anatomically impossible), and after some controversy this diagnosis was also accepted by the famous Hanoverian court physician, Johann Georg Ritter von Zimmermann

Works on Religion and Civil Society


It was after the breakdown of his health that Mendelssohn decided to "dedicate the remains of my strength for the benefit of my children or a goodly portion of my nation" – which he did by trying to bring the Jews closer to "culture, from which my nation, alas! is kept in such a distance, that one might well despair of ever overcoming it". One of the means of doing this was by "giving them a better translation of the holy books than they previously had". To this end Mendelssohn undertook his German translation of the Pentateuch and other parts of the Bible. This work called was called the Bi'ur (the explanation) (1783) and also contained a commentary, only that on Exodus having been written by Mendelssohn himself. The translation was in an elegant High German, designed to allow Jews to learn the language faster. Most of the German Jews in that period spoke Yiddish and many were literate in Hebrew (the original language of the scripture). The commentary was also thoroughly rabbinic, quoting mainly from medieval exegetes but also from Talmud-era midrash

(1783; Eng. trans. 1838 and 1852). It is a forcible plea for freedom of conscience, described by Kant as "an irrefutable book". Mendelssohn wrote:

Brothers, if you care for true piety, let us not feign agreement, where diversity is evidently the plan and purpose of Providence. None of us thinks and feels exactly like his fellow man: why do we wish to deceive each other with delusive words?


Its basic thrust is that the state has no right to interfere with the religion of its citizens, Jews included. While it proclaims the mandatory character of Jewish law for all Jews (including, based on Mendelssohn's understanding of the New Testament

, may be the most congenial to the national genius—so individuals may need different religions. The test of religion is its effect on conduct. This is the moral of Lessing's Nathan the Wise (Nathan der Weise), the hero of which is undoubtedly Mendelssohn, and in which the parable of the three rings is the epitome of the pragmatic position.

To Mendelssohn his theory represented a strengthening bond to Judaism. But in the first part of the 19th century, the criticism of Jewish dogma

" — something which Lessing was accused of being anyway by religious circles. This led to an exchange of letters between Jacobi and Mendelssohn which showed they had hardly any common ground. Mendelssohn then published his Morgenstunden oder Vorlesungen über das Dasein Gottes (Morning hours or lectures about God's existence), seemingly a series of lectures to his oldest son, his son-in-law and a young friend, usually held "in the morning hours", in which he explained his personal philosophical world-view, his own understanding of Spinoza and Lessing's "purified" ("geläutert") pantheism. But almost simultaneously with the publication of this book in 1785, Jacobi published extracts of his and Mendelssohn's letters as Briefe über die Lehre Spinozas, stating publicly that Lessing was a self confessed "pantheist" in the sense of "atheist". Mendelssohn was thus drawn into a poisonous literary controversy, and found himself attacked from all sides, including former friends or acquaintances such as Johann Gottfried von Herder and Johann Georg Hamann
