Abravanel
Gersonides
- (1288 - 1344)
Main Ideas:
- The passive or material intellect is only a
potentiality for developing pure thought which
is accomplished through the influence of the
Universal Active Intellect.
- It is is that part of the soul which
contains the sum total of the exalted thoughts
which remains immortal, thus intellectuality is
a condition of immortality.
- God knows things from their general aspect
but does not know the particulars in their
infinite ramifications.
- Scientific research must be conducted
independently of the Torah, which does not
compel men to believe what is not true.
- But truth, in accordance with modern
science, is contained in the Torah, though not
explicitly.
- The history of the Jewish people reflects
and confirms the universal truth, in whose
discovery time plays an important part.
Important Work:
- Milhamoth Adonai (The Wars of the
Lord)
Levi ben Gershon, called Gersonides, was an
astronomer, mathematician, and philosopher. He is
considered the greatest astronomer of his time.
Born in Bagnols, France, in 1288, Gersonides was a
controversial commentator on Aristotelian
philosophy, the Bible, and parts of the Talmud. His
most important mathematical work dealt with
trigonometry. His most important astronomical work
reveals Gersonides as an independent and critical
follower of the Ptolemaic tradition. He devised an
instrument for measuring the angular separation
between any two astronomical bodies, the "Jacob's
staff," which was much used in navigation,
especially in the sixteenth century.
In regard to philosophy, Gersonides was the most
radical of medieval Jewish Aristotelians. Returning
under the influence of Averroes to a more genuine
version of Aristotelianism, he makes God the
highest Form, insisting that positive attributes
may be ascribed to Him without impairing His unity.
To think otherwise is to confuse secondary beings
-- which possess their attributes derivatively --
with God who possesses His attributes primo et
per se.
Gersonides was of the Averroist school in his
interpretations and commentaries on Aristotle. His
major philosophic work, Milhamot Adonai (The
Wars of the Lord), treats many of the critical
philosophic problems of his time in the light of a
systematic position found in his commentaries on
commentaries by Averroes on Aristotle. Unlike
Maimonides, who, when faced with an unresolvable
contradiction between Aristotle and the Bible,
accepted the biblical word as primary, Gersonides
tried to accommodate biblical ideas to those of
Aristotle. Because of this he stirred up a great
deal of opposition and was suspected of heresy.
Gersonides rejects emanationism and is thus
forced to admit the existence of uncreated prime
matter. But he plays down its importance as the
barest potentiality; moreover, he derives all forms
from God and interprets the formation of matter as
a free and creative, not a necessary, process.
Divine knowledge, too, must stop short of matter.
God can exert providence over the species only, and
over the individual only in so far as it is a
member of the species. The individual human being
can as such become subject to providence only by
acquiring a share in the intelligible world.
Gersonides follows philosophical exigencies much
more closely and with much less autonomy than
Maimonides. For instead of confronting religion and
philosophy in their principles, he attempts to
achieve the reconciliations needed by the minute
analysis of specific doctrines. A large part of
Gersonides' writings is either lost or still
unpublished.

Hasdai
Crescas - (1340 - 1410)
Main Ideas:
- Criticized Maimonidean Aristotelianism,
which seemed to shelter would-be apostates:
Maimonides wrongly treated belief in God as a
commandment; rather it is presupposed by any
divine commandment.
- Aristotelian cosmology, as outlined by
Maimonides, is systematically refuted.
- There is no contradiction in the idea of
empty space or an infinite magnitude; all bodies
have weight, not a natural tendency upward or
downward.
- Citing the Talmudic view that God governs
18,000 worlds, he suggests that worlds may be
infinite, each providing its own center for the
heaviness of falling objects.
Important Works:
- Or Anonai (The Light of God)
Like almost all Jewish philosophers of the
Middle Ages, Crescas developed his philosophy in
the face of persecution and imminent personal
danger. He was born in Barcelona and was denounced
and victimized there, imprisoned and fined, despite
the recognition of his innocence. He moved and
settled in Saragossa, where he declined appointment
as rabbi of the congregation. He then became an
authority on Jewish law and ritual tradition, and
often intervened diplomatically on behalf of his
co-religionists in Aragon and neighboring kingdoms.
In a letter from him to the Jews of Avignon, he
described the personal pain he and other Jews
endured during the prosecution of Jews in Spain. It
was during this Inquisition period (1391), that he
lost his only son.
Crescas did not content himself with bemoaning
the fate of the Jews. He endeavored to defend the
spirit and doctrines of Judaism against its
religious and philosophical opponents. His
criticism of Christianity, written in Spanish, is
lost, except for those fragments which were
translated into Hebrew by Joseph ibn Shemtob in
1451.
Crescas' principal work, Or Adonai ( The
Light of God), completed in 1410, the year of his
death, was of great consequence. This work refuted
neo-Platonism and Aristotle, and implied a sharp
criticism of Gersonides and Maimonides because of
their efforts to reconcile Judaism with Greek
philosophy. Crescas rejected Aristotle's physics,
metaphysics, and axiology.
Like Gersonides, Crescas ascribes positive
attributes to God, subjecting the doctrine of
negative attributes to subtle criticism. But unlike
the former he rejects the positive attributes of
the Aristotelians. These are product of a false
intellectualism. If God is highest Thought, His
creative activity cannot be made intelligible as
flowing from His nature; He then perforce dwells
above unmoved, indifferent to the creation. God is
primarily Goodness and Love, not Thought; and His
Love is directed on the world, not Himself.
Philosophic ethics, too, suffers from a false
intellectualism. The highest goal of man is not
intellectual self-perfection but the love of God.
To make that goal a reality is the deepest purpose
of the revealed Law, and with it the highest human
goal, is accessible to all who earnestly concern
themselves with it. For only a few may possess the
intellectual capacity for philosophic knowledge;
but all have the emotional capacity for the love of
God.
Immortality does not depend on the intellect;
the soul -- much more than mere intellect -- is
essentially immortal. Like Mainmonides, Crescas
reaffirms biblical voluntarianism against the
necessitarianism of the philosophers. But
Maimonides is concerned with reconciling
philosophically the principles of the Laws with
those of philosophy, prepared to assimilate in
detail a great deal of philosophical
intellectualism. Crescas primarily attacks the
intellectualist values of the philosophers,
concerned with upholding the voluntaristic values
of Jewish tradition.
The importance of Crescas' thinking was by no
means confined to the history of Jewish philosophy.
His rejection of Aristotle, by stating that "there
are no other worlds" than the one system in which
the earth is situated, inspired such Christian
thinkers as Nicholas Cusa, Giordano Bruno, Marsilio
Facino, and Pico della Mirandola. There is little
doubt that Spinoza was indebted to Crescas for his
concept of the universe. And lastly, Crescas
defended the cause of Judaism with a spiritual
originality, radicalism, and courage uncommon in
the history of the Middle Ages.
Joseph
Albo - (c. 1380 - 1445)
Main Ideas:
- Sought to forge a philosophically defensible
Jewish creed centered on God, revelation, and
requital.
- He de-emphasized the Messianic idea, the
sorest point of Christian-Jewish polemics.
- Adopted the idea of natural law from
Aquinas, arguing, with Maimonides, that the
superiority of divine legislation lay in its
credal provision for spiritual felicity, not
just temporal welfare.
Important Work:
- Sefer-Ha-Ikkarim (Book of
Principles)
Very little is known about the life of Albo, but
the few facts that are available present
interesting aspects of medieval Jewish life amidst
Gentile surroundings. A student of Crescas, he was
well versed in mathematics, medicine, Islamic,
Christian, and Jewish philosophy, and biblical and
rabbinical learning. Albo was the representative of
the Jewish community of Daroca, where the impact
and resultant clash of Jewish, Christian, and
Islamic thought gave rise to a number of
intellectual disputes. He participated in the great
religious controversy of Tortosa (1413-14), where
he vigorously defended the Jewish viewpoint of the
Talmud.
He attained popularity among medieval Jews
because of his book Sefer-Ha-Ikkarim (Book of
Principles), a defense of Judaism against
philosophical criticism and Christianity. Although
no new ideas are introduced, the book is important
to the general philosophy of religion because it
established the criterion whereby the primary
fundamental doctrines of Judaism may be
distinguished from those of secondary
importance.
Albo stated that three principles are basic to
every revelational religion: a belief in God, the
concept of divine revelation, and divine
retributive justice.

Isaac
Abravanel - (1437-1508)
Isaac Abravanel was a Spanish Sephardic Jew who
was in the court of Alfonso V, King of Portugal,
but had to flee, at great loss of personal fortune,
when a new ruler ascended the throne. From Lisbon
he went to the House of Castile, and when the Jews
were banished from Spain, he went to Naples, once
again in the service of a king, until he was
banished by the French rulers. He then fled to
Venice where he remained until his death. He was
buried in Padua.
Abravanel is generally considered the last great
Aristotelian. Sometimes a philosophic eclectic, he
was principally concerned with the teachings of the
Bible and the modifications of doctrine expounded
by the Jews. He was a believer in the Torah and
considered the history of the Jews a revelation of
God. His studies of the Bible are frequently used
as reference by Christian scholars.

Essay: The
Interrupted Work, by Isaac Abravanel

Internet
Judah
Abravanel - (c. 1460 - 1530)
Main Ideas:
- Conceives, in Platonic fashion, of love as
the principle permeating the universe.
- Love emanates from God to the beings, and
from the beings reverts back to God.
Important Work:
- Dialoghi d'Amore (Dialogues of
Love)
Judah Abravanel, physician and philosopher, was
born in Lisbon, Portugal. He was one of the
outstanding figures of the period of transition
between the Middle Ages and the Renaissance. He
lived not only at the conjunction of two eras, but
also in contact with three cultures -- Jewish,
Spanish, and Italian. He and his father, Don Isaac
Abravanel, fled in 1483 from their native Portugal
to Spain, and thence to Italy in 1492.
Abravanel practiced medicine, but he was mainly
interested in philosophy, mathematics, and
astronomy. For a time he lectured at the
universities in Naples and Rome. The intellectuals
of both cities requested his friendship; his was a
close association with Pico della Mirandola. During
his sojourn in Italy, Abravanel assumed the name of
Leone, the translation of Judah, the Lion. He was
also a minor poet, but his influence on the poetry
of his age was felt more through his dialogues than
through his verse
His most famous works, Dialoghi di Amore
(Dialogues about Love), composed by 1502, were
first published posthumously in 1535. Probably
written initially in Italian, they were later
translated into Latin, French, Spanish, and Hebrew
and in modern times there have been translations
into English (The Philosophy of Love) and
German.
The Dialogues are landmarks in the
history of metaphysics and ethics. The central
theme of the work, akin to that of the
Symposium of Plato, is that love is the
major creative force in the universe, and that love
of God is the ultimate goal of the human soul. Thus
a circle of love leads from God's creation in love
to man's return to God through love. The work
promulgates love as a cosmic principle inseparable
from being; its spirit, the mirror of reality. The
Dialogues stressed the spiritual character of
physical beauty and helped develop the field of
aesthetic idealism. A portion of the work was
incorporated in a rabbinical commentary on the Song
of Songs.
Abravanel maintained that true happiness is the
"union of the human intellect with the Divine
intelligence," and that it is directly connected to
aesthetic enjoyment. There is a pantheistic strain
in Abravanel's philosophy, but he always emphasized
his orthodox Judaism, and tried to reconcile his
pantheistic feelings with the Biblical concept of
God.
