MODERN PHILOSOPHERS - 1
Leonardo
da Vinci
(1452-1519)
For nearly four centuries after Leonardo da
Vinci's death, humanity remained uninformed about
the scientific and philosophical performances of
one of the greatest painters of the Italian
Renaissance. Leonardo (picture)
himself published only his Treatise on
Painting in which the author combined the
display of his artistic skill and experiences with
epistemological and mathematical disquisitions. But
the immense range of Leonardo's studies, researches
and knowledge remained hidden in his diaries,
notebooks and sketchbooks, which were printed late
in the nineteenth century. They make manifest that
Leonardo anticipated many important discoveries. He
knew that the earth is a star which turns around
the sun, and that moonlight is a result of
reflection. He invented a submarine and an
airplane, a parachute, poison gas and shrapnel.
But, as one of his notes clearly indicates, he kept
his inventions secret because he did not wish these
instruments of destruction to be used.
To Leonardo, sensual experience is the
interpreter between man and nature. But the visible
form is regarded by him as the symbol of a
spiritual reality. The artist's eye is a perfect
instrument of experience but mathematical thought
has to control it, and every practice must be
founded upon sound theory. Leonardo was of a
religious mind though independent of traditional
faith. No other artist of the renaissance but
Leonardo could have dared to portray St. John the
Baptist and Bacchus, the pagan god, as resembling
one another like brothers. And none of that age
could combine the character of an altar piece with
that of a psychological study, as Leonardo did in
his "Last Supper."

Ben
Jonson
(1573-1637)
Starting as a bricklayer, Ben Jonson (picture)
made his way to become a dramatic poet who held a
dominant place in English literary life during the
last years of Queen Elizabeth and the reign of
James I. In his progress to this position, Jonson
was a soldier who distinguished himself on the
battlefield. He fought many duels, and attacked
many of his fellow writers with the weapon of
sarcasm, though he respected the gentle
Shakespeare. Because he killed an actor, Jonson
narrowly escaped capital punishment. While in
prison he became a convert to the Catholic Church,
but twelve years thereafter, he returned to
Protestantism.
Ben Jonson's best known works are his plays
Every Man in His Humour (1598) and
Volpone (1605). In his essays Timber
or Discoveries Made Upon Men and Matters, he
dealt mostly with the dignity and value of
literature, while he also cast sidelights on the
daily life of his time. Algernon Charles Swinburne
praised these essays, and put them above those of
Francis Bacon. Recent scholars have discovered that
Jonson was much indebted to Latin authors, but they
do not deny that he also relied on personal
observation and expressed original views.

Uriel
Acosta
(1590-1647)
Born in Portugal, the descendant of a Marrano
family, religiously observant of Catholicism, the
young Acosta prepared himself for the priesthood.
But, tortured by doubts about the Christian
religion, he decided to flee to Holland. Here he
embraced Judaism, not because he was convinced of
the truth of his new faith, but he was resolved to
deny his former beliefs. He defied Jewish
orthodoxy, the very basis of Judaism, because he
was incapable of integrating himself into the
Jewish community or of understanding its precarious
situation and vital needs. His attacks upon the
fundamental doctrines of Christianity, which he
wrote as a member of the Jewish congregation of
Amsterdam angered the congregation because they
felt the Christian authorities who had given the
Jews refuge would be offended. Banished, he
recanted, revolted anew, was banished anew, and
ostracized for seven years.
No longer able to endure solitude, he was
willing to withstand the most severe penance in
order to be allowed to reenter the Jewish
community. But the rigors of the ceremony destroyed
his will to survive. Soon thereafter, he committed
suicide, unrepenting and irreconcilable. To some
extent, he was the victim of his temper, but more
so of an era in which it was impossible for an
independent thinker to live unharmed outside a
religious community.
Many novelists and dramatists, Jew and non-Jew,
have idealized his life and thoughts, for the
poetic transfiguration of his fate is the tragedy
of an uprooted man in revolt against tradition and
any community based on tradition -- the tragedy of
a humiliated man, unable to live in isolation,
whose only alternative was death. He entitled his
autobiography Exemplar Humanai Vitae
(Example of a Human Life), but his life was
certainly anything but typical.

Duc
de La Rochefoucauld, François VI [Prince
de
Marsillac]
(1613-1680)
The almighty Cardinal Richelieu and his
successor, the no less powerful Cardinal Mazarin,
were defied by the Duke of La Rochefoucauld
(picture) who,
descending from a family as noble and as old as the
Plantagenets, treated the statesmen -- virtually
absolute rulers over France -- as snobs. Fearless
on the military and political battlefield, La
Rochefoucauld lacked and detested brutality. He was
a brilliant soldier, but no warrior. Twice exiled
because of his frankness, La Rochefoucauld was more
inclined to observation and meditation, and
thinking gave him more solace for his experiences
without mellowing his impressions.
His sentiments were benevolent but his eyes and
ears were inexorable. He called himself an
Epicurean and skeptic. In fact, La Rochefoucauld, a
grand-seigneur of the highest rank in the
French kingdom, was melancholic. What he had
experienced and observed he condensed with
admirable artistic skill in his Maxims
(1665). He had seen the triumph of intrigues, the
victory of meanness over generosity, and he had
penetrated into the secrets of statesmen and kings,
of court-cabals and political plotters. He had
participated in foreign and civil wars, and felt
himself defeated and disappointed. From all these
occurrences he drew the conclusion that egoism is
the rule of human actions.
His feelings were in constant revolt against
this knowledge of his comprehensive mind. The
Maxims scandalized the society of his time
but were eagerly read and translated into many
languages, and their resigned wisdom continues to
attract philosophers and laymen in France and
elsewhere, despite all cultural changes.

Ralph
Cudworth
(1617-1688)
A theologian, Ralph Cudworth (picture)
constantly warned against the overestimation of
dogmatic differences. He was Regius professor of
Hebrew at Cambridge University, England, from 1645
to 1688 and while there became known as the leader
of the Cambridge Platonists. In his True
Intellectual System of the World (1678), he
concentrated upon the refutation of all the
atheistic schools, particularly those of
Democritus, Lucretius, and Hobbes. However, he did
consider it incumbent upon him to present fairly
the disputed doctrines. This caused many critics,
among them Dryden, to express apprehension lest
readers of these presentations become converts to
atheism, and stop reading before perusing
Cudworth's refutation.
Cudworth maintained that a primitive
monotheistic creed could be found even in ancient
paganism. In his explanation of the universe, he
tried to avoid both the assumption of chance and
the hypothesis of a steady interference of God.
Therefore, he introduced the concept of "plastic
nature" which was to act in a creative manner in
accordance with its own laws. This concept, very
likely, influenced Spinoza, and the nineteenth
century French philosopher, Paul Janet, whose work
was based on the idea of "plastic nature."
When the Stuarts resumed their reign of England
in 1660, Cudworth encountered some governmental
difficulties. They hesitated to reappoint him
because he had been an intimate friend of Thurloe,
Cromwell's secretary, and Cromwell had consulted
Cudworth in 1655 on the question of the readmission
of the Jews to England.

Arnold
Geulincx
(1624-1669)
For twelve years, Geulincx was professor at the
University of Louvain, Belgium, a stronghold of
Catholic orthodoxy. Then he was converted to
Calvinism, and became professor at the University
of Leyden, Holland, at that time the center of
learning, and an asylum for scholars who had been
persecuted in their native country. He wrote all of
his works in Latin, and died before his principal
books, namely Ethica and Metaphysica,
could be published.
Although Geulincx often and intensely dealt with
metaphysical questions, he was even more interested
in ethics, but did not separate one from another.
On the contrary, his ethics is founded upon
metaphysics, though he also used psychological
experience for his argumentation. He summed up his
doctrine in the words: Ita est, ergo ita sit
(So it is, therefore be it so). His view on life is
colored with optimistic resignation. His steady
confidence in God does not shut his eyes to the
shortcomings of the existing world; if he expressed
the idea of what Leibniz, about twenty-five years
after Geulincx' death, has called the
"pre-established harmony," he did not intend to
assert that the existing world was good or the best
of all possible but rather that it were good enough
for Man who is morally and intellectually far from
perfection.
Geulincx was a man of moderation, opposite to
any kind of extremism. Following Descartes, he
regarded doubt as the force that makes Man ask for
truth. He appreciated the educational value of
provisional skepticism, but demanded that mature
men must believe in God whom he regarded as the
first cause of all things, without denying second
causes. Geulincx therefore, while adopting the
Scholastic term of occasional cause, held that
occasionalism was an indispensable hypothesis, apt
to explain natural and mental facts, but was far
from the radical standpoint of Malebranche who
published his views only five years after Geulincx'
death.

Pierre
Bayle
(1647-1706)
Although not widely known today, Pierre Bayle
(picture) was a very
influential philosopher in the seventeenth century.
And throughout the first half of the eighteenth
century, Bayle was one of the most widely-read
thinkers of that period. Born into a Huguenot
(French Calvinist) family, he eventually concerted
the Catholicism and then, after a few years,
converted to the Reformed faith and spent many
years as a teacher of Calvinism. He was born in
Carlat-le-Comte, France. In 1675 he took the chair
of philosophy at Sedan until forced into exile at
the University of Rotterdam in 1681, where he
published a strong defense of liberalism and
religious toleration. Bayle was dismissed from the
university in 1693 following the accusation that he
was an agent of France and an enemy of
Protestantism. In 1696 he completed his major work,
the Historical and Critical Dictionary, a
skeptical analysis of philosophical and theological
arguments, which became the most widely owned book
in private libraries in France throughout the
eighteenth century.
According to Bayle, critical reason prepares one
for faith and faith must not fear critical reason
or erudition. One should rely only on faith
(fideism) and, for there to be faith, there must be
an obligation to natural judgment. He raised such
issues as the mystery of salvation and the
questions of justification and sanctification. He
also addressed the problem of evil and said that
neither logic nor evidence can overcome someone who
doubts the goodness of God. Natural reason cannot
explain why God allows evil. For Bayle, all areas
of human belief show the incapacity of reason and
the need for faith. His skepticism is directed
against all intellectual confidence. Bayle was
opposed by outraged theologians. He criticizes the
very foundation of his culture's intellectual
inheritance. He tries to show that Christianity
becomes superstitious when it departs from simple
faith. Always, one must avoid overextension of
human claims and hold to simple faith.

Emanuel
Swedenborg
(1688-1772)
Emanuel Swedenborg (picture)
was born in Stockholm and studied at Uppsala.
Emerson once remarked that it would require "a
colony of men" to do justice to Swedenborg's work.
Goethe adopted several of Swedenborg's ideas.
Balzac founded essential views on human and cosmic
nature on Swedenborg's doctrine. So have many
modern authors. And today there are thousands of
faithful Swedenborgians in Europe and America.
Until his fifty-third year, Swedenborg had been
known as a great engineer, a scholar and a
scientist. He had written important books on
mathematics, mechanics, physiology and astronomy.
Then he experienced a grave crisis. As a young boy,
he had already yearned to know God and had eagerly
discussed theological questions with clergymen. In
his advanced age he became more and more anxious
about his spiritual conditions. He was deeply
impressed by dreams in which he had visions.
In 1757 he became convinced of having witnessed
in one of his visions the Last Judgment. In his
Arcana Coelestia (in 12 volumes, 1749-56) he
offered a mystical interpretation of the first
books of the Old Testament which, according to him,
was purposely written to prevent profanation, and
by exposing their true meaning, he developed his
own religious and philosophical system.
Of fundamental importance to Swedenborg's system
is his doctrine of correspondence, which, as he
asserts, was known to the ancient people in Canaan,
Chaldea, Syria and Egypt and since had been
forgotten. Greek travelers who visited these
countries misunderstood the doctrine and changed it
into fabulous stories which, however, allow a
reconstruction of the true sense. According to this
doctrine, everything in our visible, natural or
material world corresponds to something in the
invisible, spiritual astral world. The total
natural world corresponds to the spiritual world
not only in general but in particular. Thus,
everything in the natural world represents an
idea.
Swedenborg distinguishes four styles in the
world. The first, the style of the most ancient
mankind which extends until Noah and the Flood, has
been transcribed by Moses but has an offspring in
the third style, the prophetic, while the second,
the historic, extends from Abraham to the time of
the kings of Judah and Israel. The fourth style,
that of David's psalms, is mixed with the prophetic
style and common speech. The restitution of the
most ancient religion is Swedenborg's purpose. He
claims to be sent by God to announce the end of the
Christian and the beginning of the New Jerusalem
dispensation. He recognizes Jesus Christ as Savior
but rejects the Christian doctrine of Trinity and
excludes the Epistles of Paul from the Biblical
Canon. God is one, both in essence and person. He
is uncreated, eternal, infinite, omnipotent, the
union of love and wisdom.
Related with the doctrine of correspondence is
Swedenborg's doctrine of degrees. Man is a
recipient of three degrees, and capable of thinking
analytically and rationally of things within the
sphere of nature, and of spiritual and celestial
things above the natural sphere. At the highest
degree, man may see God.
Swedenborg's behavior showed nothing eccentric.
Apart from his visions, he was very practical and
free from emotion. He was a strict vegetarian and
admonished his disciples to refrain from eating
meat. His modesty and simplicity won him many
friends and admirers even among those who did not
share his opinions.

Carolus
Linnaeus
(1707-1778)
On New Year's Day of 1730, the dean of the
University of Upsala, Sweden, found on his desk a
peculiar form of season's greetings. It was a
manuscript, written by an unknown student and
entitled Preliminaries on the Marriage of
Plants. In his preface, the author of the
manuscript confessed to his incapability of making
verses, and excused himself for having, instead,
written a juvenile treatise, in which he handled
the analogy between plants and animals as he saw
it.
This manuscript contained the germ of Carolus
Linnaeus' (picture)
great contributions to botany. Searching for a
principle for the classification of plants,
Linnaeus, dissatisfied with any division according
to color, use of the season of flowering, found the
key in the reproductive parts of the plants, and
classified them according to their different ways
of producing offshoots. In addition to this sexual
system, Linnaeus also contributed to the natural
sciences by originating the binominal system of
naming plants and animals. The first name indicates
the genus and the second, the particular species by
Latin or Greek words. In this way, Linnaeus made
his naming system internationally applicable.
Linnaeus furthermore contributed to mineralogy and
ethnology by his report on his scientific
expedition to Lapland and his miscellaneous essays.
He was a charming writer because he was a loving
character and a unique observer. As a great
scientists said, Linnaeus saw plants "just as an
insect sees them."
Born in a small farm cottage in a remote
district of Sweden, Linnaeus as a little boy
already astonished his relatives and teachers by
his interest in, and knowledge of, plants. He liked
to remember his native village and preserved his
country-boy outlook even after he had become
internationally renowned. It is an almost general
custom among botanists to make a botanical
excursion on Linnaeus' birthday, although modern
botany has ceased to concern itself with the
flowers in the fields and has become a kind of
department of physics and chemistry.

Julien
Offray de La
Mettrie
(1709-1751)
This "scapegoat of 18th century materialism," as
Friedrich Albert Lange rightly called him, has been
blamed and despised by many who had not read a
single page of his books. La Mettrie (picture)
was a physician in the French army. In this
capacity he entered into conflict first with
medical routine, then with his superiors, and,
finally, the government. He was dismissed, and
emigrated to Holland. In his books L'homme
machine and L'homme plante (1748), La
Mettrie demonstrated by comparative methods the
relationship between man other living beings, and
proceeded to a theory of the evolution of
organisms. He stated that psychical life is
observable already on the lowest level of the
evolution. Investigating the functions of the
brain, La Mettrie tried to discern various stages
of its formation which are of primary importance in
the development of mental life. Also, he protested
again an evaluation of the moral character of men
which depends on the acceptance of religious
doctrines. Although La Mettrie was decried as a
crude materialist, he also influenced idealist
philosophers. To him Goethe owes the inspiration
for his botanical ideas.

Samuel
Johnson
(1709-1784)
Samuel Johnson (picture)
was most popular among his British contemporaries,
especially the citizens of London, as "the
philosopher," but he disliked philosophers just as
he disliked country life, music, learned women.
Whigs, history for its own sake and a lot of other
things. To him, Berkeley was a madman, Hume nothing
but an infidel and Voltaire, whose literary skill
he admired, a rascal. He was a critic of literature
but he held that the fundamental aspects of life
were not proper subjects for poetry.
Although Johnson was not a profound thinker, he
was a man of deep convictions, acquired by hard
experiences. His poem The Vanity of Human
Wishes (1749) outlines his philosophy of life,
which he formulated again and again in satirical
and earnest, resigned and irate sayings. To him
life is mostly litter, and rarely sweet. It is
endurable only because there are short intervals of
satisfaction. The end of writing is to enable
mankind "better to enjoy life or better to endure
it." Poetry must stand the test of reason and
common sense. Fabulous images, Johnson maintained,
have worn thin.
In politics, Johnson was a staunch Tory, in
religious questions uncompromisingly orthodox. He
demanded that literature, in which he was mainly
interested, does not have to explain the riddles of
existence, but that it should support moral and
religious doctrines and defend the king and the
Church. Much of this philosophy was expressed by
Johnson in casual remarks in his Lives of the
Poets (1779-81). However, he is best known not
by his own writings but rather by the book of his
biographer James Boswell, who wrote down Johnson's
remarks about daily life, literature, politics, and
contemporary history. The biography presents a
genial man, who -- though difficult to deal with, a
sarcastic conversationalist, sometimes sound,
sometimes queer -- was always sincere and
original.

Claude
Adrien
Helvétius
(1715-1771)
Claude Adrien Helvétius (picture)
was a French philosopher and financier, born in
Paris, whose thought influenced Jeremy Bentham, and
through him, the British utilitarians.
Many moralists of many ages have complained that
personal interest in the pursuit of happiness is
the only efficient principle of human actions. The
awareness of this fact has made some of them
melancholy, others resigned to that fate, and still
others fundamentally pessimistic, or indignant, or
hypocritical. There has been no lack of efforts to
deny such statements or to change the character of
man if the statement were true. Helvétius,
contrary to all of these critics of egoism, was the
first to draw an optimistic conclusion from the
conviction that personal interest was the real rule
of human behavior. His book De l'Esprit (On
the Mind, 1758), in which Helvétius
explained his views and founded them upon
Condillac's sensualism, was condemned by the
Sorbonne and burned in Paris after the judges had
declared it dangerous to state and society.
Helvétius was a clever financier by
profession. He used his large income for the
promotion of literature, philosophy and social
welfare. He was one of the first to insist on
taking the social environment and economic
conditions into consideration before sentencing a
defendant. Not this demand but other suggestions
advanced by Helvétius were later realized by
the legislation of the First French Republic and by
Napoleon.

Johann
Georg Hamann
(1730-1788)
During a stay in London, where he was bound to
become acquainted with British business methods,
Johann Georg Hamann (picture),
a native of Königsberg , Prussia, had a
mystical experience which made him a grim adversary
of rationalism and the spirit of enlightenment that
fascinated most of his contemporaries. With the aid
of allegorical interpretation, Hamann regarded the
Bible as the fundamental book of all possible
knowledge, including that of nature. Allegory and
symbol gave Hamann truer knowledge than notions.
Myths and poetry were to him of greater validity
than scientific research and logical
conclusions.
Language was the key that opens the door to
reality. Hamann was a past master in sensing the
unconscious tendencies of speech. But in his style
there are no consequences, no development of ideas.
He tried to grasp the flux of life, but, according
to his own avowal, often forgot the meaning of the
similes he had used and to which he alluded in
later pages of the same treatise. His fugitive
associations, therefore, are of greater value than
his efforts to express his intentions
elaborately.
Devout and coquettish, excessive in his piety
and repentance of transgressions with which his
imagination remained fascinated, Hamann tried to
embrace spirit and sensuality, sometimes
illuminating their relations, sometimes becoming
hopelessly confused. His writings were inspired by
sublime earnestness and brilliant irony. He accused
the rationalistic spirit of his age of ignoring God
and nature, human genius, creative action and the
enjoyment of real life. His views deeply impressed
Herder, Goethe, Friedrich Heinrich Jacobi, Hegel
and Kierkegaard.

Johann
Kasper Lavater
(1741-1801)
Protestant orthodoxy and pietism, formerly
opposed to each other, became allied in the mind of
Johann Kasper Lavater (picture),
whose complicated character made him sometimes
obstinate, sometimes humble. He always tried to
realize, by his thinking and conduct of life, the
ideal of Christian humanity. He also tried to
combine belief in miracles with the modern cult of
poetic genius. Trained in psychological
self-analysis, he was, nevertheless a helpless
illusionist, whose extreme gullibility exposed him
to the suspicion of being insincere.
A staunch adversary of rationalism, Lavater was
often the victim of fanatics, charlatans and crooks
who exploited his longing or miracles and the
manifestation of supernatural forces.
Notwithstanding his attempts to reach simple faith,
an unsophisticated belief in the Word of the Bible,
he was never satisfied with plain truth, and was
always ready to take divination for knowledge and
phantoms for reality because they stirred his
imagination more than did reason. But when he was
not occupied with the propaganda for his ideas,
Lavater always proved to be a noble-minded and
charitable man.
However, it was not his theological writings
that made him famous but his Physiognomics
(1774-78), which was translated into several
languages. This work contains a wealth of material
and has inspired psychologists and poets, but it
lacks scientific method. Lavater, who collected and
interpreted a great number of historical or
artistic portraits, was convinced that his
physiognomical studies would promote not only a
knowledge of man but also a mutual love of men.
