Gilbert de la Porrée, also known as
Gilbert of Poitiers, Gilbertus
Porretanus or Pictaviensis (1070 –
September 4, 1154) was a scholastic logician and theologian.
Life
He was born in Poitiers. He was educated under Bernard of
Chartres and Anselm of Laon. After teaching for about
twenty years in Chartres,
he lectured on dialectics and theology in Paris (from 1137). At Paris Stephen of
Alinerre was among his pupils. In 1141 he returned to Poitiers,
being elected bishop in the following year. At Poitier Jordan Fantosme
was one of his pupils.
Gilbert's heterodox opinions regarding the doctrine
of the Trinity drew upon his works the
condemnation of the church. The Council of Rheims
in 1148, at which both Gilbert and Stephen were present, procured
papal sanction for four propositions opposed to certain of
Gilbert's tenets, and his works were condemned until they should be
corrected in accordance with the principles of the church. Gilbert
seems to have submitted quietly to this judgment; he yielded assent
to the four propositions, and remained on friendly terms with his
antagonists till his death.
Works
Gilbert is almost the only logician of the 12th century who is
quoted by the greater scholastics of the succeeding age. His chief
logical work, the treatise De sex principiis, was regarded
with a reverence almost equal to that paid to Aristotle, and furnished matter for numerous
commentators, amongst them Albertus Magnus. Owing to the fame of
this work, he is mentioned by Dante as the Magister sex
principiorum. The treatise itself is a discussion of the
Aristotelian categories, specially of the six subordinate
modes.
Gilbert distinguishes in the ten categories two classes, one
essential, the other derivative. Essential or inhering (formae
inhaerentes) in the objects themselves are only substance,
quantity, quality and relation in the stricter sense of that term.
The remaining six, when, where, action, passion, position and
habit, are relative and subordinate (formae assistentes). This
suggestion has some interest, but is of no great value, either in
logic or in the theory of knowledge. More important in the history
of scholasticism are the theological consequences to which
Gilbert's realism led him.
In the commentary on the treatise De Trinitate
(erroneously attributed to Boetius) he proceeds
from the metaphysical notion that pure or abstract
being is prior in nature to that which is. This pure being is God, and must be distinguished from the
triune God as known to us. God is incomprehensible, and the
categories cannot be applied to determine his existence. In God
there is no distinction or difference, whereas in all substances or
things there is duality, arising from the element of matter.
Between pure being and substances stand the ideas or forms, which
subsist, though they are not substances. These forms, when
materialized, are called formae substantiales or
formae nativae; they are the essences of things, and in
themselves have no relation to the accidents of things. Things are
temporal, the ideas perpetual, God eternal. The pure form of
existence, that by which God is God, must be distinguished from the
three persons who are God by participation in this form. The form
or essence is one, the persons or substances three. It was this
distinction between Deitas or Divinitas and
Deus that led to the condemnation of Gilbert's
doctrine.
