4. Eduard von Hartmann,
Phänomenologie des sittlichen Bewusstseins,
Phenomenology of Moral Consciousness, German ed. p. 451. Born 1842,
von Hartmann was originally an officer in the Prussian army. Because
of an illness, he retired from military service and took up an
intensive study of philosophy. In 1869 his
Philosophie des Unbewussten
(Philosophy of the Unconscious)
appeared, and made him famous almost overnight. Of the many other works
he wrote, this book remained his most famous. Rudolf Steiner describes
a personal impression of von Hartmann, whom he visited in Berlin in
1888 following a philosophical correspondence with him over some years.
This account may be found in Chapter IX of Steiner's autobiography. Steiner's
Wahrheit und Wissenschaft
(Truth and Knowledge),
published in this present volume, was dedicated to von Hartmann. The
latter died in 1906.
5. In his
Atomistik des Willens,
Atomic Theory of Will,
Ger. ed., Hamburg, 1891, 2 vols. p. 213. Robert Hamerling, the Austrian
poet-philosopher was born March 24, 1830. He early showed ability in
poetry, and although from poor parentage, the generosity of friends
enabled him to attend the gymnasium in Vienna, and afterward the
University there. In the revolutionary movements which swept Europe
in 1848, Hamerling joined the student legion in the Vienna revolt.
The collapse of the uprising in 1849 made it necessary for him to
hide for a long time in order to escape arrest. Later he studied
natural science and philosophy. In 1855 he was appointed master at
the gymnasium in Trieste. Many years of ill health caused him finally
to retire on a government pension in 1866. In comparatively
comfortable circumstances, Hamerling spent the remainder of his life
in his home near Gratz, devoting himself to writing until his death
on July 13, 1889. He is referred to as “one of the most
remarkable poets of the Austrian school; his poems are full of life
and color.” His most popular work was
Ahasver in Rom,
Ahasver in Rome (1866),
with Nero as principal character.
Der König von Sion,
The King of Zion, (1869)
is generally considered to be his masterpiece. In 1888 his
appeared, and was reviewed with extensive comment by Rudolf Steiner. His
Amor und Psyche
was published in 1882; his novel
described Greek life in the age of Pericles. In 1870 his
drama concerning the French Revolution,
Danton und Robespierre,
was published. Rudolf Steiner commented on this drama in his Speech
and Drama Course given in 1924, and in fact, many references to
Hamerling and his work appear in books and lectures by Rudolf
Steiner, including the latter's autobiography.
Wilhelm Friedrich Hegel (1770–1831). A voluminous literature on
Hegel and Hegelian thought exists in English, including biographical
studies, translations, and commentaries on his writings. Consult any
standard encyclopedia for details.
Gottlieb Fichte. Born in 1762, Fichte studied at Meissen, Pforta,
Jena, and Leipzig with the intention of becoming a clergyman. After a
teaching position in Switzerland, and enroute to another in Poland,
he met Kant, under whose influence he wrote his
Study for a Critique of All Revelation.
The printer neglected to place his
name on the title-page, and people thought the work had been written
by Kant. When the true identity of the author became known, Fichte
was hailed as a philosopher of outstanding merit. He lectured at
Jena, Berlin and Erlangen. In 1807 he was made Rector of the
University of Berlin. His death in 1814 occurred when he was at the
height of his fame. Rudolf Steiner made extensive reference to
Fichte, basing his doctoral thesis (published in enlarged form in the
present volume as
(Truth and Knowledge)
on Fichte's scientific
teachings, but perhaps his most memorable study of Fichte's life and
thought was contained in a public lecture given in Berlin on December
The Spirit of Fichte Present in Our Midst.

Wolfgang von Goethe, born Frankfurt a.M., August 28, 1749. Poet,
dramatist, scientist, traveler, state minister, etc., author of
and many other works. Died in Weimar,
March 22, 1832. In August 1781 the Grand Duchess Amalia of
Saxe-Weimar founded the
the Journal of Tiefurt,
to which Goethe contributed at her invitation. When Rudolf Steiner
was active as editor of the natural scientific writings of Goethe
at the Goethe-Schiller Archives in Weimar, he published proof that the
Fragment über die Natur,
The Fragment concerning Nature,
which had appeared in the Journal of Tiefurt was definitely
to be attributed to Goethe
(Schriften der Goethe-Gesellschaft,
Publications of the Goethe Society, ed. by Bernhard Suphan, Weimar,
Vol. VII, 1892, article by Rudolf Steiner). Thus, just 110 years
after the Fragment had appeared, Rudolf Steiner showed its importance
and its relationship to Goethe's work. In the edition of Goethe's
works published by Prof. Joseph Kürschner (1853–1902) (the
volumes of Goethe's natural scientific writings edited by Rudolf
Steiner), the Fragment appears at the beginning of the essays
“On Natural Science in General,”
Vol. XXXIV, p. 1. The Fragment appeared in an English translation with
notes by George Adams under the title,
Nature — An Essay in Aphorisms,
Anthroposophical Quarterly, London, Vol. VII, No. 1, Easter, 1932,
pp. 2–5. In his
Goethe's Conception of the World,
Rudolf Steiner describes this Fragment as “the essay in which the
seeds of the later Goethean world-conception are already to be found.
What is here expressed as dim feeling, later developed into clear,
definite thought.” In similar vein, George Witkowski in his
well-known biography of Goethe (Leipzig, 1899) describes this
Fragment as “the seed from which came all of Goethe's great
thoughts about nature.”
Wilhelm Joseph von Schelling (1775–1854). Often referred to as
the Proteus among philosophers, Schelling was noted for his
ever-changing alertness and brightness of mind and expression. Goethe
(see note 16, above) had a very high regard for him,
and spoke of him as “the most congenial philosopher I know.”
Schelling had a profound influence among the thinkers of his time, including
philosophers of France and England. His last years were dedicated to
what he termed “positive philosophy,” radically different
from the philosophy of identity, the transcendental idealism, and the
pantheistic tendencies of his earlier time. Rudolf Steiner made
extensive reference to Schelling in his writings and lectures, on
various occasions praising that philosopher's “important
inspirations and suggestions for what must afterwards be said by
Anthroposophy, directly out of spiritual vision, on many points of
Christianity.” Steiner further spoke of Schelling, “who
really always made a significant impression whenever he appeared in
public — the short, thick-set man, with the extremely
impressive head, and eyes which even in extreme old age were
sparkling with fire, for from his eyes there spoke the fire of Truth,
the fire of Knowledge.” (From a lecture given at Dornach,
Switzerland, Sept. 16, 1924) Perhaps Steiner's greatest study of
Schelling is to be found in his
Die Rätsel der Philosophie,
The Riddles of Philosophy, Vol. I, Ch. 7.
For English translations of Schelling and further details on his life,
see any standard encyclopedia.
Kant, German philosopher, was born in Königsburg April 22,
1724. He entered the university there in 1740, enrolled for the
study of mathematics and physics. His studies were interrupted by
the death of his father, which left him in poverty. After he
supported himself by tutoring for 9 years, the kindness of a friend
enabled him to resume his studies, to graduate as a doctor and to
qualify as a privatdocent. He occupied this position for 15 years.
His lectures widened from physics to include much philosophy.
Finally, after unsuccessful attempts, in 1770 he was given the chair
of logic and metaphysics at Königsburg. In 1781 his
Kritik der reinen Vernunft,
Critique of Pure Reason
appeared, and in 1783, his
After the appearance of the 2nd edition of the
in 1787, Kant became famous everywhere
in German intellectual circles, and his views were regarded as those
of an oracle. From 1792–97 he was engaged in a struggle with
the government concerning his religious views. In 1794 he withdrew
from society, and gave up all teaching except for one public lecture
course on logic. In 1797 Kant terminated a teaching activity that
had extended over 42 years. He died in Königsburg on February
12, 1804 near the end of his 80th year. Little more than five feet
tall, deformed in his right shoulder, his chest almost concave, Kant
had a weak constitution. He never married, and followed an
unchanging program of activities from youth to old age. For example,
he never failed to rise at 5 o'clock, studied for 2 hours, lectured
for 2 more, and spent the rest of the morning at his desk. He dined
at a restaurant and spent the afternoon in conversation with
friends. He then walked for about an hour — a walk which for
years followed exactly the same course — studied for 2 hours
more, and retired between 9 and 10. He was a prolific reader,
especially in history, science, travel, and philosophy. He knew
English history and literature intimately, especially in the period
of Queen Anne. He read little of Goethe or Schiller, but often
re-read Voltaire and Rousseau. He had little interest in nature, and
in 80 years never traveled more than 40 miles from his native
Königsburg. For further biographical details, works and
translations, consult any standard encyclopedia.
28. Otto Liebmann,
Zur Analysis der Wirklichkeit,
Contribution to the Analysis of Reality, Strassburg, 1880, p. 28.
Otto Liebmann (1840–1912) was well known for his writings on
Kant's philosophical world-view.
Peter Müller, German physiologist and comparative anatomist,
born in Coblentz, July 14, 1801. He studied at the University of
Bonn, and was appointed to a professorship in physiology there in
1826. In 1843 he accepted the call to the chair of anatomy and
physiology at Berlin University, which position he held with great
honor until his death, April 28, 1858. He did much research in
physiology, particularly in relation to human speech and hearing.
His great work was the
Handbuch der Physiologie des Menschen,
1833–40. (The English translation was made by Dr. William
Baly, publ. London 1842). This work opened a new period in the study
of physiology, and Müller is considered the main figure in the
developments in this field in the mid-19th century. In his Handbuch
Müller developed an entirely new principle which he called
“the law of specific energy of sense substances.” This
he expressed as follows: “The kind of sensation following
stimulation of a sensory nerve does not depend on the mode of
stimulation, but upon the nature of the sense organ. Thus, light,
pressure, or mechanical stimulation acting on the retina and optic
nerve invariably produces luminous impressions.” It is to this
law that Steiner refers at this point.
Die Welt als Wille und Vorstellung
The World as Will and Representation,
Four Books, publ. 1819 by Brockhaus, Leipzig. (English translation by Haldane
& Kemp, 1883) Ref. Book I, par. 1, Ger. ed. Biographical data and
translations of Schopenhauer's works, as well as extensive
commentaries on his ideas have been published in English
translation. Consult any standard encyclopedia for details. Rudolf
Steiner edited a collected edition of the writings of Schopenhauer,
12 vols. with introduction by Steiner, publ. 1894.
DuBois-Reymond, German physiologist and educator. Born Berlin,
November 7th, 1818, in 1836 he entered the University of Berlin,
where his teacher was Johannes Müller (see note 32,
above). In 1840 he became the latter's assistant in physiology. His great work
was the study of animal electricity, and his famous book was
Researches on Animal Electricity,
1848–84. For many
years he exerted great influence as a teacher. In 1858, upon the
death of Müller, he was appointed to the latter's chair in
physiology. In 1851 he had been admitted to the Academy of Sciences
in Berlin; in 1867 he became its permanent secretary. His closest
friend after Müller's death was von Helmholtz, who also had
been a student of Müller. DuBois-Reymond died in Berlin on
November 26, 1896. Rudolf Steiner makes many references to his work
in lectures and writings.
Kant-Laplace primordial nebula. On Immanuel Kant,
see note 27,
above. Pierre Simon Marquis de Laplace (1749–1827), was a
French mathematician and astronomer who, at the age of 24 was named
“the Newton of France” for certain of his discoveries.
In the years 1799–1825 his great work, the
which, as its author stated, “offers a complete solution of
the great mechanical problem presented by the solar system,”
appeared in 5 volumes, published in Paris. In his second great work, the
Exposition du système du monde,
appeared his statement of his famous “nebular hypothesis,”
the origins of which he seems to attribute to Buffon, apparently
unaware that Immanuel Kant had at least partially anticipated him in his
General History of Nature,
published in 1755. Rudolf Steiner's criticism of the Kant-Laplace
theory of the primordial nebula may be found in various places in
his lectures and writings.
Heinrich Haeckel (1834–1919), German biologist, originally a
physician in Berlin, became Privatdozent at Jena, afterward
extraordinary professor of comparative anatomy, later professor of
zoology, a chair established for him at Jena. This position he
occupied for 43 years with intervals for zoological travels to
various parts of the world. When Darwin's
Origin of the Species
appeared in 1859, Haeckel was deeply influenced by it, so that he
became “the apostle of Darwinism in Germany.” Among
Haeckel's famous books are his
General Morphology (1866),
Natural History of Creation (1867)
(1899), English title,
The Riddle of the Universe,
publ. 1901. By his 60th birthday Haeckel had published 42 works of some
13,000 pages, plus many monographs. Rudolf Steiner knew Haeckel
personally, and in his autobiography. Chapter 15, Steiner recorded a
very interesting and perceptive impression of the great scientist.
The “genealogical tree” of Haeckel to which Steiner
refers is set forth in its original form in Haeckel's
and developed in his later writings.
Hume (1711–1776), Scottish philosopher and historian. Albert
Einstein wrote, “If one reads Hume's books, one is amazed that
many sometimes highly esteemed philosophers after him have been able
to write so much obscure stuff and even to find grateful readers for
it. Hume has permanently influenced the development of the best
philosophers who came after him.” Among those influenced by
Hume may be numbered Immanuel Kant, William James, George Santayana,
and Bertrand Russell. Hume's writings and biographical and critical
works concerning him and his ideas can be located by consulting any
Julius Schröer was born in Pressburg in 1825. In 1867 he was
made professor of Literature in the Technical College of Vienna. In
addition to his lectures on the history of German poetry as such, he
lectured on Goethe and Schiller, on Walther von der Vogelweide, on
German Grammar and Speech, etc. Rudolf Steiner was a pupil of
Schröer, and refers to him in detail in his autobiography and
in lectures. It was Schröer who recommended Steiner to Prof.
Kürschner for the position of editor of Goethe's natural
scientific writings. (See note 16, above)
Schröer died in Vienna in 1900, and Rudolf Steiner has left an
unforgettable word portrait and estimate of him in his
Riddles of Man, publ. Berlin, 1916.
July 1884 to September 1890, Rudolf Steiner was active as tutor in
the home of Ladislaus (1834–1905) and Pauline (1846–1916)
Specht at Kolingasse 19, Vienna IX. He taught their four sons,
Richard, Arthur, Otto, and Ernst. Richard Specht (1870–1932)
became a well-known author of many works including biographical
studies of Gustav Mahler, Richard Strauss, Franz Werfel, Brahms, and
Beethoven. Steiner gives details of this pedagogical activity in his
autobiography. Chapter VI.
Mayreder (1858–1938), Austrian writer, also known as a
painter. Her entire life was passed in Vienna and surroundings. She
was the author of a number of popular novels. In addition, she was
active in the movement for woman suffrage in Austria, at one time
sharing in the direction of the movement itself, and editing its
periodical. She wrote the libretto for Hugo Wolf's only opera,
Der Corregidor (1896).
Rudolf Steiner refers to Rosa Mayreder in his
autobiography. Chapter IX.

that living organisms come from other living organisms, as opposed
to abiogenesis. The author of the modern formulation of “the
fundamental law of biogenesis” was Fritz Müller (1864).
Haeckel (see note 54, above) called Müller's
formulation “the biogenetic fundamental law,” which can
be stated briefly as the teaching that in its development from the
egg to adult stage, the animal tends to pass through a series of
stages which recapitulate the stages through which its ancestry
passed in the development of the species from a primitive form. In
other words, the development of the individual is a condensed
expression of the development of the race.

Stewart Mill (1806–1873). A stern parent, James Mill taught
his son Greek at the age of three, and at seven he studied Plato's
dialogues. When he was eight he had to teach his sister Latin. His
introduction to the utilitarian teachings of Bentham (the greatest
happiness to the greatest number) at the age of fifteen was decisive
for his life. His great work,

rights, and in the second half of the i9th century his influence

great philosopher but a great reformer in philosophy.” For
