Moses Mendelssohn - Lavater

Lavater

So far, Mendelssohn had devoted his talents to philosophy and criticism; now, however, an incident turned the current of his life in the direction of the cause of Judaism. In April 1763, Johann Kaspar Lavater, then a young theology-student from Zurich, made a trip to Berlin, where he visited the already famous Jewish philosopher with some companions. 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's essay on Christian Evidences, with a preface where he publicly challenged Mendelssohn to refute Bonnet or if he could not then to "do what wisdom, the love of truth and honesty must bid him, what a Socrates would have done if he had read the book and found it unanswerable". Mendelssohn answered in an open letter in December 1769: "Suppose there were living among my contemporaries a Confucius or a Solon, I could, according to the principles of my faith, love and admire the great man without falling into the ridiculous idea that I must convert a Solon or a Confucius." The ongoing public controversy cost Mendelssohn much time, energy and strength.

Lavater later described Mendelssohn in his book on physiognomy, "Physiognomische Fragmente zur Beförderung der Menschenkenntnis und Menschenliebe" (1775–1778), as "a companionable, brilliant soul, with piercing eyes, the body of an Aesop—a man of keen insight, exquisite taste and wide erudition frank and open-hearted"—ending his public praise with the wish of Mendelssohn recognizing, "together with Plato and Moses... the crucified glory of Christ". 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.
