Christian Wolff (less correctly Wolf, German: [vɔlf] ; also known as Wolfius; ennobled as Christian Freiherr von Wolff in 1745; 24 January 1679 – 9 April 1754) was a German philosopher. Wolff was the most eminent German philosopher between Leibniz and Kant. His main achievement was a complete oeuvre on almost every scholarly subject of his time, displayed and unfolded according to his demonstrative-deductive, mathematical method, which perhaps represents the peak of Enlightenment rationality in Germany.


Wolff was also the creator of German as the language of scholarly instruction and research, although he also wrote in Latin, so that an international audience could, and did, read him. A founding father of, among other fields, economics and public administration as academic disciplines, he concentrated especially in these fields, giving advice on practical matters to people in government, and stressing the professional nature of university education.

Wolff was born in Breslau, Silesia (now Wrocław, Poland), into a modest family. He studied mathematics and physics at the University of Jena, soon adding philosophy. In 1703, he qualified as Privatdozent at Leipzig University, [4] where he lectured until 1706, when he was called as professor of mathematics and natural philosophy to the University of Halle. By this time he had made the acquaintance of Leibniz (the two men engaged in an epistolary correspondence), [5] of whose philosophy his own system is a modified version. At Halle, Wolff at first restricted himself to mathematics, but on the departure of a colleague, he added physics, and soon included all the main philosophical disciplines.

However, the claims Wolff advanced on behalf of philosophical reason appeared impious to his theological colleagues. Halle was the headquarters of Pietism, which, after a long struggle against Lutheran dogmatism, had assumed the characteristics of a new orthodoxy. Wolff's professed ideal was to base theological truths on mathematically certain evidence. Strife with the Pietists broke out openly in 1721, when Wolff, on the occasion of stepping down as pro-rector, delivered an oration "On the Practical Philosophy of the Chinese" (Eng. tr. 1750), in which he praised the purity of the moral precepts of Confucius, pointing to them as an evidence of the power of human reason to reach moral truth by its own efforts.

On 12 July 1723 Wolff held a lecture for students and the magistrates at the end of his term as a rector. [6] Wolff compared, based on books by the Flemish missionaries François Noël (1651–1729) and Philippe Couplet (1623–1693), Moses, Christ and Mohammed with Confucius. [7] According to Voltaire, professor August Hermann Francke had been teaching in an empty classroom but Wolff attracted with his lectures around 1,000 students from all over. [8] In the following up Wolff was accused by Francke of fatalism and atheism. [9]

As a consequence, Wolff was ousted in 1723 from his first chair at Halle in one of the most celebrated academic dramas of the 18th century. His successors were Joachim Lange, a pietist, and his son. His enemies had gained the ear of the king Frederick William I and told him that, if Wolff's determinism were recognized, no soldier who deserted could be punished, since he would only have acted as it was necessarily predetermined that he should. This so enraged the king that he immediately deprived Wolff of his office, and commanded him to leave Prussian territory within 48 hours or be hanged. The same day Wolff passed into Saxony, and presently proceeded to Marburg, Hesse-Kassel, to whose university (the University of Marburg) he had received a call even before this crisis, which was now renewed. The Landgrave of Hesse received him with every mark of distinction, and the circumstances of his expulsion drew universal attention to his philosophy. It was everywhere discussed, and over two hundred books and pamphlets appeared for or against it before 1737, not reckoning the systematic treatises of Wolff and his followers.

According to Jonathan I. Israel "the conflict became one of the most significant cultural confrontations of the 18th century and perhaps the most important of the Enlightenment in Central Europe and the Baltic countries before the French Revolution." [10] In 1726 Wolff published his Discours, in which he again mentioned the importance of listening to music put on pregnant Chinese women [note 1] , and had reworded some on Moses. At the University of Marburg, as one of the most popular and fashionable university teachers in Europe, he increased matriculation figures within five years by about 50%.

The Prussian crown prince Frederick defended Wolff against Joachim Lange and ordered the Berlin minister Jean Deschamps, a former pupil of Wolff, to translate Vernünftige Gedanken von Gott, der Welt und der Seele des Menschen, auch allen Dingen überhaupt into French. [11] Frederick proposed to send a copy of Logique ou réflexions sur les forces de l'entendement humain to Voltaire in his first letter to the philosopher from 8 August 1736. In 1737 Wolff's Metafysica was translated into French by Ulrich Friedrich von Suhm (1691–1740). [12] Voltaire got the impression Frederick had translated the book himself.

In 1738 Frederick William begun the hard labour of trying to read Wolff. [13] In 1740 Frederick William died, and one of the first acts of his son and successor, Frederick the Great, was to acquire him for the Prussian Academy. [14] Wolff refused, [15] but accepted on 10 September 1740 an appointment in Halle. His entry into the town on 6 December 1740 took on the character of a triumphal procession. In 1743, he became chancellor of the university, and in 1745, he received the title of Freiherr (Baron) from the Elector of Bavaria. But his matter was no longer fashionable, he had outlived his power of attracting students, and his class-rooms remained, while not empty, then certainly emptier than they had been during his heyday in Marburg.

When Wolff died on 9 April 1754, he was a very wealthy man, almost entirely due to his income from lecture-fees, salaries, and royalties. He was also a member of many academies and probably the first scholar to have been created hereditary Baron of the Holy Roman Empire on the basis of his academic work. His school, the Wolffians, was the first school, in the philosophical sense, associated with a German philosopher. It dominated Germany until the rise of Kantianism.

Christian Wolff redefined philosophy as the science of the possible, and applied it in a comprehensive survey of human knowledge to the disciplines of his time. Wolffian philosophy has a marked insistence everywhere on a clear and methodic exposition, holding confidence in the power of reason to reduce all subjects to this form. He was distinguished for writing copies in both Latin and German. Wolff's teachings held virtually undisputed sway in Germany till the Kantian revolution, and even after that, Wolff continued to be regarded as one of the most important philosophers from German-speaking lands.

Until the 1960s, it was usually maintained by historians that Wolff's philosophy amounted to a common-sense adaptation or watering-down of the Leibnizian system; or, more charitably, Wolff was said to have methodized and "reduced" to dogmatic form the thoughts of his great predecessor. The Wolffian system retains the determinism and optimism of Leibniz, but the monadology recedes into the background, the monads falling asunder into souls or conscious beings on the one hand and mere atoms on the other. The doctrine of the pre-established harmony also loses its metaphysical significance (while remaining an important heuristic device), and the principle of sufficient reason is once more discarded in favor of the principle of contradiction which Wolff seeks to make the fundamental principle of philosophy.

Wolff had philosophy divided into a theoretical and a practical part. Logic, sometimes called philosophia rationalis, forms the introduction or propaedeutics to both.

Theoretical philosophy had for its parts ontology or philosophia prima as a general metaphysics, [16] which arises as a preliminary to the distinction of the three special metaphysics [17] on the soul, world and God: [18] [19] rational psychology, [20] [21] rational cosmology, [22] and rational theology. [23] The three disciplines are called empirical and rational because they are independent of revelation. This scheme, which is the counterpart of religious tripartition in creature, creation, and Creator, is best known to philosophical students by Kant's treatment of it in the Critique of Pure Reason . In the "Preface" of the 2nd edition of Kant's book, Wolff is defined "the greatest of all dogmatic philosophers." [24] Wolff was read by Kierkegaard's father Michael Pedersen, and his son himself was influenced by both Wolff and Kant to the point of resuming the tripartite structure and philosophical content to formulate his own three Stages on Life's Way . [25]

Practical philosophy is subdivided into ethics, economics and politics. Wolff's moral principle is the realization of human perfectionseen realistically as the kind of perfection the human person actually can achieve in the world in which we live. It is perhaps the combination of Enlightenment optimism and worldly realism that made Wolff so successful and popular as a teacher of future statesmen and business leaders. [26]


Wolff's most important works are as follows:

  1. What happened in Halle should not be seen as an isolated case, but as trendy and fashionable. Around 1720 Chinese porcelain was loaded in enormous quantities to Europe. In the Albrechtsburg the Meissen porcelain manufactory had been started up to copy it and Chinoiserie was popular among artists and buyers.

Gottfried Wilhelm Leibniz German mathematician and philosopher

Gottfried Wilhelm (von) Leibniz was a prominent German polymath and one of the most important logicians, mathematicians and natural philosophers of the Enlightenment. As a representative of the seventeenth-century tradition of rationalism, Leibniz's most prominent accomplishment was conceiving the ideas of differential and integral calculus, independently of Isaac Newton's contemporaneous developments. Mathematical works have consistently favored Leibniz's notation as the conventional expression of calculus. It was only in the 20th century that Leibniz's law of continuity and transcendental law of homogeneity found mathematical implementation. He became one of the most prolific inventors in the field of mechanical calculators. While working on adding automatic multiplication and division to Pascal's calculator, he was the first to describe a pinwheel calculator in 1685 and invented the Leibniz wheel, used in the arithmometer, the first mass-produced mechanical calculator. He also refined the binary number system, which is the foundation of all digital computers.

Metaphysics Branch of philosophy dealing with the nature of reality

Metaphysics is the branch of philosophy that examines the fundamental nature of reality, including the relationship between mind and matter, between substance and attribute, and between potentiality and actuality. The word "metaphysics" comes from two Greek words that, together, literally mean "after or behind or among [the study of] the natural". It has been suggested that the term might have been coined by a first century CE editor who assembled various small selections of Aristotle’s works into the treatise we now know by the name Metaphysics.

Wilhelm Wundt German physician, physiologist, philosopher and professor

Wilhelm Maximilian Wundt was a physician, physiologist, philosopher, and professor, known today as one of the founders of modern psychology. Wundt, who distinguished psychology as a science from philosophy and biology, was the first person ever to call himself a psychologist. He is widely regarded as the "father of experimental psychology". In 1879, at University of Leipzig, Wundt founded the first formal laboratory for psychological research. This marked psychology as an independent field of study. By creating this laboratory he was able to establish psychology as a separate science from other disciplines. He also formed the first academic journal for psychological research, Philosophische Studien, set up to publish the Institute's research.

Hermann Lotze German philosopher

Rudolf Hermann Lotze was a German philosopher and logician. He also had a medical degree and was well versed in biology. He argued that if the physical world is governed by mechanical laws, relations and developments in the universe could be explained as the functioning of a world mind. His medical studies were pioneering works in scientific psychology.

P. F. Strawson British philosopher

Before that, he was appointed as a college lecturer at University College, Oxford, in 1947, and became a tutorial fellow the following year, until 1968. On his retirement in 1987, he returned to the college and continued working there until shortly before his death. His portrait was painted by the artists Muli Tang and Daphne Todd.

Carl Gustav "Peter" Hempel was a German writer and philosopher. He was a major figure in logical empiricism, a 20th-century movement in the philosophy of science. He is especially well known for his articulation of the deductive-nomological model of scientific explanation, which was considered the "standard model" of scientific explanation during the 1950s and 1960s. He is also known for the raven paradox.

<i>Théodicée</i> book by Gottfried Wilhelm Leibniz

Essais de Théodicée sur la bonté de Dieu, la liberté de l'homme et l'origine du mal, more simply known as Théodicée, is a book of philosophy by the German polymath Gottfried Leibniz. The book, published in 1710, introduced the term theodicy, and its optimistic approach to the problem of evil is thought to have inspired Voltaire's Candide. Much of the work consists of a response to the ideas of the French philosopher Pierre Bayle, with whom Leibniz carried on a debate for many years.

Cosmology (philosophy) discipline directed to the philosophical contemplation of the universe as a totality, and to its conceptual foundations

Philosophical cosmology, philosophy of cosmology or philosophy of cosmos is a discipline directed to the philosophical contemplation of the universe as a totality, and to its conceptual foundations. It draws on several branches of philosophy—metaphysics, epistemology, philosophy of physics, philosophy of science, philosophy of mathematics, and on the fundamental theories of physics. The term cosmology was used at least as early as 1730, by German philosopher Christian Wolff, in Cosmologia Generalis.
