Denis Diderot (October 5, 1713 – July 31, 1784)
was a French
philosopher,
art critic and writer. He was a prominent figure
during the
Enlightenment and is
best known for serving as chief editor of and contributor to the
Encyclopédie.
Diderot also contributed to literature, notably with
Jacques le fataliste et son maître
(
Jacques the Fatalist and his Master), which emulated
Laurence Sterne in challenging
conventions regarding
novels and their
structure and content, while also examining
philosophical ideas about
free will. Diderot is also known as the author of
the dialogue,
Le Neveu de
Rameau (
Rameau's Nephew), upon which many
articles and sermons about consumer desire have been based. His
articles included many topics of the Enlightenment.
Life and death
Denis
Diderot was born in the eastern French city of Langres
and
commenced his formal education in the Lycée Louis le
Grand
. In 1732, he earned a master of arts degree
in philosophy. He abandoned the idea of entering the clergy and
decided instead to study law. His study of law was short-lived; in
1734, Diderot decided instead to become a writer. Because of his
refusal to enter one of the learned professions, he was disowned by
his father, and for the next ten years he lived a rather bohemian
existence.
In 1743, he further alienated his father by marrying
Antoinette Champion, a devout
Roman Catholic. The match was considered
inappropriate due to Champion's low social status, poor education,
fatherless status, lack of a dowry, and, at thirty-two, being four
years his senior. The marriage produced one surviving child, a
girl. Her name was Angélique, after both Diderot's dead mother and
sister. The death of his sister, a nun, from overwork in the
convent may have affected Diderot's opinion of religion. She is
assumed to have been the inspiration for his novel about a nun,
La Religieuse, in which he depicts a woman who is forced
to enter a monastery, and suffers at the hands of the other nuns in
the community.
He had affairs with the writer
Madame
Puisieux and with
Sophie Volland.
His letters to
Sophie Volland contain
some of the most vivid of all the insights that we have of the
daily life of the philosophic circle of Paris during this time
period.
Though his work was broad and rigorous, it did not bring him
riches. He secured none of the posts that were occasionally given
to needy men of letters; he could not even obtain the bare official
recognition of merit which was implied by being chosen a member of
the
Académie française.
When the time came for him to provide a
dowry
for his daughter, he saw no alternative than to sell his library.
When
Catherine II of Russia
heard of his financial troubles she commissioned an agent in Paris
to buy the library. She then requested that the philosopher retain
the books in Paris until she required them, and act as her
librarian with a yearly salary.
In 1773 and 1774, Diderot spent some months
at the empress's court in Saint Petersburg
.
Diderot
died of gastro-intestinal problems in Paris
on July 31,
1784, and was buried in the city's Église
Saint-Roch
. His heirs sent his vast library to Catherine
II, who had it deposited at the National Library
of Russia
.
Early works
Diderot's earliest works included a translation of
Temple Stanyan's
History of Greece
(1743); with two colleagues,
François-Vincent Toussaint
and
Marc-Antoine Eidous, he
produced a translation of
Robert James's
Medical
Dictionary (1746–1748) at about the same time he published a
free rendering of
Shaftesbury's
Inquiry Concerning Virtue and Merit (1745), with some
original notes of his own. In 1746, he wrote his first original
work: the
Pensées philosophiques, and he added to this a
short complementary essay on the sufficiency of
natural religion. He then composed a volume
of bawdy stories,
Les bijoux
indiscrets (1748); in later years he repented this work.In
1747, he wrote the
Promenade du sceptique, an
allegory pointing first at the extravagances of
Catholicism; second, at the
vanity of the pleasures of the world which is the rival of the
church; and third, at the desperate and unfathomable uncertainty of
the philosophy which professes to be so high above both church and
world.
Diderot's celebrated
Lettre sur les aveugles ("Letter on
the Blind") (1749), introduced him to the world as a daringly
original thinker. The subject is a discussion of the interrelation
between man's reason and the
knowledge
acquired through perception (the
five
senses). The title, "Letter on the Blind For the Use of Those
Who See" also evoked some ironic doubt about the who exactly were
"the blind" under discussion. In the essay, a blind English
mathematician named Saunderson argues that since knowledge derives
from the senses, then mathematics is the only form of knowledge
that both he and a sighted person can agree about. It is suggested
that the blind could be taught to read through their sense of touch
(a later essay,
Lettre sur les sourds et muets, considered
the case of a similar deprivation in the
deaf
and
mute). What makes the
Lettre
sur les aveugles so remarkable, however, is its distinct, if
undeveloped, presentation of the theory of
variation and
natural
selection.
This powerful essay ... revolves around a remarkable
deathbed scene in which a dying blind philosopher, Saunderson,
rejects the arguments of a providential God during his last
hours.
Saunderson's arguments are those of a Neo-Spinozist, Naturalist, and
Fatalist, using a sophisticated notion of
the self-generation and
natural evolution of species without Creation or supernatural
intervention.
The notion of "thinking
matter" is upheld and the "argument from design" discarded ... as
hollow and unconvincing.
The work appeared anonymously ... and was vigorously
suppressed by the authorities.
Diderot, who had been under police surveillance since
1747, was swiftly identified as the author ... and was imprisoned
for some months at Vincennes, where he was
visited almost daily by Rousseau, at the
time his closest and most assiduous ally.
After signing a letter of submission and promising never to write
anything prejudicial against religion ever again (with the result
that from then on his most controversial works were henceforth
published only after his death), Diderot was released from the
dungeons of the
Vincennes fortress after
three months. In collaboration with
d'Alembert, he subsequently embarked on his
greatest project, The
Encyclopédie, ou dictionnaire raisonné des sciences, des arts et
des métiers.
Encyclopédie
André Le Breton, a bookseller
and printer, approached Diderot with a project for the publication
of a translation of
Ephraim
Chambers' Cyclopaedia,
or Universal Dictionary of Arts and Sciences into French,
first undertaken by the Englishman
John Mills, and followed by the
German
Gottfried Sellius. Diderot
accepted the proposal. During this translation his creative mind
and astute vision transformed the work. Instead of a mere
reproduction of the
Cyclopaedia, he persuaded Le Breton to
enter upon a new work, which would collect all the active writers,
ideas, and knowledge that were moving the cultivated class of the
Republic of Letters to its
depths; however, they were comparatively ineffective due to their
lack of dispersion. His enthusiasm for the project was transmitted
to the publishers; they collected a sufficient capital for a more
vast enterprise than they had first planned.
Jean le Rond d'Alembert was
persuaded to become Diderot's colleague; the requisite permission
was procured from the government.
In 1750 an elaborate prospectus announced the project to a
delighted public, and in 1751 the first volume was published. This
work was very unorthodox and had many forward-thinking ideas for
the time. Diderot stated within this work, "An encyclopedia ought
to make good the failure to execute such a project hitherto, and
should encompass not only the fields already covered by the
academies, but each and every branch of human knowledge." Upon
encompassing every branch of knowledge this will give, "the power
to change men's common way of thinking." This idea was profound and
intriguing, as it was one of the first works during the
Enlightenment. Diderot wanted to give all people the ability to
further their knowledge and, in a sense, allow every person to have
any knowledge they sought of the world. The work, implementing not
only the expertise of scholars and Academies in their respective
fields but that of the common man in their proficiencies in their
trades, sought to bring together all knowledge of the time and
condense this information for all to use. These people would
amalgamate and work under a society to perform such a project. They
would work alone in order to shed societal conformities, and build
a multitude of information on a desired subject with varying view
points, methods, or philosophies. He emphasized the vast abundance
of knowledge held within each subject with intricacies and details
to provide the greatest amount of knowledge to be gained from the
subject. All people would benefit from these insights into
different subjects as a means of betterment; bettering society as a
whole and individuals alike.
This message under the
Ancien
Régime would severely dilute the regime's ability to
control the people. Knowledge and power, two key items the upper
class held over the lower class, were in jeopardy as knowledge
would be more accessible, giving way to more power amongst the
lower class. An encyclopedia would give the layman an ability to
reason and use knowledge to better themselves; allowing for upward
mobility and increased intellectual abundance amongst the lower
class. A growth of knowledge amongst this segment of society would
provide power to this group and a yearning to question the
government. The numerated subjects in the
folio were not just for the good of the
people and society, but were for the promotion of the state as
well. The state did not see any benefit in the works, instead
viewing them as a contempt to contrive power and authority from the
state.
Diderot's work was plagued by controversy from the beginning; the
project was suspended by the courts in 1752. Just as the second
volume was completed accusations arose, regarding seditious
content, concerning the editors entries on religion and natural
law. Diderot was detained and his house was searched for
manuscripts for subsequent articles. But the search proved
fruitless as no manuscripts could be found. They were hidden in the
house of an unlikely confederate—
Chretien de
Lamoignon Malesherbes, the very official who ordered the
search. Although Malesherbis was a staunch absolutist-loyal to the
monarchy, he was sympathetic to the literary project. Along with
his support, and that of other well placed influential
confederates, the project resumed. Diderot returned to his efforts
only to be constantly embroiled in controversy.
These twenty years were to Diderot not merely only a time of
incessant drudgery, but harassing persecution and desertion of
friends. The
ecclesiastical party
detested the
Encyclopédie, in which they saw a rising
stronghold for their philosophic enemies. By 1757 they could endure
it no longer. The subscribers had grown from 2,000 to 4,000, a
measure of the growth of the work in popular influence and power.
The
Encyclopédie threatened the governing
social classes of France (
aristocracy) because it took for granted the
justice of
religious tolerance,
freedom of thought, and the value
of
science and
industry. It asserted the doctrine that the main
concern of the nation's government ought to be the nation's common
people. It was believed that the
Encyclopédie was the work
of an organized band of conspirators against society, and that the
dangerous ideas they held were made truly formidable by their open
publication. In 1759, the
Encyclopédie was formally
suppressed. The decree did not stop the work, which went on, but
its difficulties increased by the necessity of being clandestine.
Jean le Rond d'Alembert
withdrew from the enterprise and other powerful colleagues,
including
Anne Robert Jacques
Turgot, Baron de Laune, declined to contribute further to a
book which had acquired a bad reputation. Diderot was left to
finish the task as best he could. He wrote several hundred
articles, some very slight, but many of them laborious,
comprehensive, and long. He damaged his eyesight correcting
proof and editing the
manuscripts of less competent contributors. He
spent his days at workshops, mastering manufacturing processes, and
his nights writing what he had learned during the day. He was
incessantly harassed by threats of
police
raids. The last copies of the first volume were issued in 1765. At
the last moment, when his immense work was drawing to an end, he
encountered a crowning mortification: he discovered that the
bookseller, fearing the government's displeasure, had struck out
from the proof sheets, after they had left Diderot's hands, all
passages that he considered too dangerous. The monument to which
Diderot had given the labor of twenty long and oppressive years was
irreparably mutilated and defaced. It was twelve years, in 1772,
before the subscribers received the final 27 folio volumes of the
Encyclopédie, ou dictionnaire raisonné des sciences, des arts
et des métiers since the first volume had been
published.
Other works
Although the
Encyclopédie was Diderot's monumental piece,
he was the author of many other works that sowed nearly every field
of intellectual interest with new and creative ideas. He wrote
sentimental
plays,
Le Fils naturel (1757) and
Le Père
de famille (1758), accompanying them with essays on theatrical
theory and practice, including
Les Entretiens sur Le Fils
naturel (
Conversations on Le Fils naturel), in which
he announced the principles of a new
drama—the
serious, domestic,
bourgeois drama of real
life, in opposition to the stilted conventions of the classical
French stage. His
art criticism was
also highly influential. Diderot's
Essais sur la peinture
was described by
Johann
Wolfgang von Goethe, as "a magnificent work, which speaks even
more helpfully to the poet than to the painter, though to the
painter too it is as a blazing torch."
Diderot's most intimate friend was the
philologist Friedrich Melchior Grimm. They were
brought together by their friend in common at that time,
Jean-Jacques Rousseau.
Grimm wrote
newsletters to various high personages in Germany
, reporting
the happenings of art and literature in Paris, then the
intellectual capital of Europe.
Diderot helped Grimm between 1759 and 1779, by writing an account
of the annual exhibitions of paintings in the
Paris Salon. These reports are highly readable
pieces of art criticism. According to
Charles Augustin Sainte-Beuve,
they initiated the French into a new way of laughing, and
introduced people to the mystery and purport of colour by ideas.
"Before Diderot,"
Anne Louise Germaine de
Staël wrote, "I had never seen anything in pictures except dull
and lifeless colours; it was his imagination that gave them relief
and life, and it is almost a new sense for which I am indebted to
his genius."
Jean-Baptiste
Greuze was Diderot's favorite contemporary artist. Greuze's
most characteristic pictures were the rendering in colour of the
same sentiments of domestic virtue and the
pathos of common life, which Diderot had attempted to
represent upon the stage. Diderot was above all things interested
in the life of individuals. He did not care about the abstract life
of the race, but the incidents of individual character, the
fortunes of a particular family, the relations of real and concrete
motives in this or that special case. He was delighted with the
enthusiasm of a born
casuist in curious
puzzles of right and wrong, and in devising a conflict between the
generalities of
ethics and the conditions of
an ingeniously contrived practical dilemma. Diderot's interest
expressed itself in
didactic and
sympathetic form. However, in two of his most remarkable pieces,
this interest is not sympathetic, but ironic.
Jacques le fataliste (written in
1773, but not published until 1792 in German and 1796 in French) is
similar to
Tristram
Shandy and
The Sentimental Journey. His dialogue
Le Neveu de Rameau
(Rameau's Nephew) is a "farce-tragedy" reminiscent of the
Satires of
Horace. A favorite
classical author of Diderot's, Horace's words
Vertumnis,
quotquot sunt, natus iniquis are quoted at the top of the
Nephew. Diderot's intention in writing the dialogue is
disputed; whether it is merely a
satire on
contemporary manners, or a reduction of the theory of
self-interest to an absurdity, or the
application of
irony to the ethics of ordinary
convention, or a mere setting for a discussion about
music, or a vigorous dramatic sketch of a parasite and
a human original. Whatever its intent, it is a remarkable
conversation, representing an era of that held the art of
conversation in the highest regard. The writing and publication
history of the
Nephew is likewise a bit mysterious.
Diderot never saw the work through to publication during his
lifetime, but there is every indication it was of continual
interest to him. Though the original draft was written in 1761, he
made additions to it year after year until his death twenty-three
years later. Goethe's translation (1805) was the first introduction
of
Le Neveu de Rameau to the European public. After
executing it, he gave back the original French manuscript to
Friedrich Schiller, from whom he
had it. No authentic French copy of it appeared until the writer
had been dead for forty years (1823). Diderot's miscellaneous
pieces range from a graceful trifle like the
Regrets sur ma
vieille robe de chambre (
Regrets for my Old Dressing
Gown) up to
Le Rêve de d'Alembert, where he plunges
into the depths of the controversy as to the ultimate constitution
of
matter and the
meaning of life. Diderot was
not a coherent and systematic thinker, but rather "a philosopher in
whom all the contradictions of the time struggle with one another"
(
Rosenkranz). He
did not develop a comprehensive system of
materialism, but he may have made some
contributions to the atheistic materialist works of his friend
Paul Henri Thiry, baron
d'Holbach.
