The Character of the Volume
Moses Mendelssohns Kleine philosophische Schriften is not a single sustained treatise but a collected edition of shorter pieces by Moses Mendelssohn, gathered and edited by Johann Georg Müchler and introduced by Daniel Jenisch, whose “Skizze seines Lebens und Charakters” (“Sketch of His Life and Character”) stands at the front. The title itself signals the nature of the book: these are Mendelssohn’s kleine — shorter, occasional, “minor” in scale though not in seriousness — philosophical writings, the essays, dialogues, letters and verse translations that appeared alongside his major books. The volume thus presents Mendelssohn in the several roles he occupied for the German reading public of the late Enlightenment: popular philosophical essayist, dialogue writer in the manner of Shaftesbury and Plato, correspondent on questions of sentiment and mortality, and mediator of Hebrew poetry and Jewish thought.
Jenisch’s Sketch of Life and Character
The book opens with Jenisch’s biographical and characterological essay. Its purpose is introductory and commemorative: it presents Mendelssohn to readers as a philosopher formed outside the universities and academies, and it treats his life as the natural prologue to the writings that follow — his origins and early education, his entry into the intellectual world of Berlin, his friendships among the German men of letters of his day, and the temperament that contemporaries remarked on: mildness, clarity, a combative patience in controversy, and a double loyalty to philosophical reason and to the Jewish tradition in which he was raised. The sketch is, in effect, a portrait of the sage designed to frame the shorter pieces as the natural expression of that character, rather than a critical biography in the modern sense.
The Collected Shorter Writings
The pieces assembled in the volume are varied in form and subject, and the contents page shows a mixture of didactic prose, moral reflection, epistolary writing and verse translation. Among the pieces the volume is known to contain are:
- An “Anweisung” — an instruction or guidance addressed to young people on how they should read the old writers. It belongs to the pedagogical side of the Enlightenment: the formation of judgment through the disciplined reading of the ancients, written in Mendelssohn’s characteristic plain and orderly prose.
- A “Betrachtung über die Ungleichheit und Gesellschaft” — a reflection on inequality and society. This places the collection in conversation with the eighteenth-century debate over the origins of social inequality, a debate in which Mendelssohn had already taken part as a translator and respondent to Rousseau.
- A “Brief der Cenie über die Furcht vor dem Tode” — a letter attributed to “Cenie” on the fear of death, one of the volume’s several pieces written in epistolary or quasi-dramatic form. Fear of death and the grounds for equanimity before it were abiding themes of Mendelssohn’s philosophy, and the letter form allowed him to treat them with the intimacy of a correspondence rather than the apparatus of a treatise.
- An “Elegie an die Burg Zion gerichtet” — an elegy addressed to the stronghold of Zion, showing that the collection also reaches into the territory of Hebrew poetry and lament, rendered into German verse.
- A piece titled “Rabbi Judaja Hapnini Badraschi Prüfung” — a text presented under the name of a medieval Hebrew authority and his “examination” or “test,” evidence of Mendelssohn’s interest in making the Hebrew literary and philosophical heritage accessible to German readers.
These titles, taken together with the dialogues and letters that make up much of the rest of the book, indicate the shape of the whole: a sampler of Mendelssohn’s shorter work rather than a system. Some pieces are composed as conversations after classical and Shaftesburian models — the volume’s pages are populated by figures with the names of philosophical dialogue (Socrates, Euthydemus, Theophanes, Clytander) and of the early-modern debate over matter and perception (Hylas and Philonous, drawn from Berkeley) — while others take the form of letters between cultivated correspondents, including female voices such as Isabella.
Recurring Themes
The vocabulary that runs through the volume maps its intellectual territory. Much of it concerns the metaphysics of the soul and of knowledge: the power of thought, its relation to the brain and to bodily organs, the modifications of the mind, matter and extension, the proofs of immateriality. Mendelssohn’s argument that the soul’s simplicity and immortality can be secured by philosophical analysis is present here in its shorter, more popular form rather than in the elaborate architecture of Phaedon. A second cluster of concerns is ethical and aesthetic: sensation, feeling, virtue, happiness, the education of the heart, the moral uses of poetry. A third is theological and Jewish: the Talmud and the Torah, the Jews and their civil position, the name Jehovah, the relation of revelation to reason. A fourth points toward the controversies of Mendelssohn’s last years: the recurrence of Spinoza’s name, of Lessing, and of d’Alembert indicates that the volume also carries material from, or adjacent to, the pantheism dispute and the public arguments over Lessing’s legacy that occupied Mendelssohn at the end of his life.
Reading the Collection
The book is best understood as an anthology with a commemorative purpose: Jenisch’s sketch supplies the life, and the shorter writings supply the mind, in the forms in which Mendelssohn most often addressed the general public — the essay, the dialogue, the letter and the translated poem. It shows him as a philosopher who wrote for readers rather than for schools, moving easily between metaphysics and moral reflection, between German letters and Hebrew sources, and between the calm exposition of ideas and the heat of public controversy. For the historian of the German Enlightenment it preserves the occasional, fugitive side of Mendelssohn’s authorship; for the general reader it offers the most accessible entrée into his thought, in the mode in which his contemporaries first encountered it.
The Hebrew item is more than an isolated curiosity. It is a German rendering of Jedaiah ha-Penini’s Bechinat Olam (Examination of the World), a medieval Hebrew ethical meditation on the transience of worldly goods and the conduct of life. Placing such a text beside metaphysical dialogues and aesthetic letters makes the volume a practical demonstration of Mendelssohn’s larger project: Hebrew moral literature can be read as philosophy in German, and the Jewish tradition can supply edifying wisdom rather than only confessional argument. The translated laments and poems serve a related end, extending the anthology from abstract reasoning to feeling, consolation, and moral instruction.
Methodologically, the dialogues are experiments in public reasoning. The Socratic settings allow objections to be voiced and answered, while the idealist interlocutors drawn from Berkeley signal that Mendelssohn is willing to bring the strongest challenge to ordinary realism into the open rather than argue only within Wolffian categories. The letters, for their part, treat sentiment, sympathy, and the education of the heart as philosophical topics, and the use of female correspondents shows the Enlightenment ideal of conversation as a scene of philosophizing. In this volume, genre is not decoration: dialogue and letter are the forms in which Mendelssohn’s shorter philosophy becomes sociable and testable.
Read together, the pieces show how tightly Mendelssohn connected his questions: the analysis of sensation and thought supports aesthetics and ethics; the defense of the soul’s simplicity and immortality underwrites religion and providence; and the Jewish and Hebrew materials keep revelation, law, and the civil position of Jews within the same philosophical conversation. The collection’s significance is therefore twofold: it preserves the occasional, public-facing side of Mendelssohn’s authorship, and it shows the German Enlightenment being conducted across confessional and linguistic boundaries—Hebrew source, German prose, and English, French, and classical philosophical interlocutors—without settling into a single school system.
