I.
Life and Works
Bonaventure (born Giovanni di Fidanza)
(picture) was born at
Bagnorea in 1221 and entered the Franciscan Order
probably about the year 1243. He studied at the
University of Paris, where he was a disciple of
Alexander of Hales, the first Franciscan master of
that university; Bonaventure later succeeded his
master in the chair of philosophy. He taught at the
university from 1248 to 1255 and took part, along
with Thomas Aquinas, in the debate against William
of Saint Amour, adversary of the Mendicants.
In October of 1257 the degree of Doctor was
bestowed on Bonaventure at the university.
Nominated General of the Order in the same year, he
left his studies to devote himself to the affairs
of the Franciscans. At this time he wrote the new
Constitutions of the Order and the biography of St.
Francis of Assisi which helped to pacify the
various Franciscan currents.
In 1273 he was named Cardinal and Bishop of
Alvano. He died in Lyons in 1274 while the Council
being held in that city was still in session.
Bonaventure has been honored with the title "Doctor
Seraphicus."
His principal works are: Commentaries on the
Four Books of Sentences of Peter Lombard;
Itinerarium mentis in Deum; De reductione
artium ad theologiam; and
Breviloquium.
II.
Doctrine: General Notions
Bonaventure is the theorist of what, in a
practical way, was mirrored in the life of St.
Francis of Assisi. Francis had been entirely
consumed by love of God and of Christ crucified;
and the sacred stigmata, visible in his body, were
the manifestation of what had already been verified
within the very depths of his saintly spirit. In
this mystical union with God and with Christ, St.
Francis had found the basis of brotherhood not only
with men but also with all beings, and the human
and physical world was revealed before his eyes as
a sanctuary in which all things spoke to him of
God.
Bonaventure wished to theorize on the life of
the Poverello and to build it into a perfect system
of the Christian life. For this purpose he did not
borrow the teachings of the speculative rationalism
of Aristotle, but looked to Augustinianism, which
already boasted a long tradition in the Church. Its
voluntarism, which placed love of God at the center
of every activity; its theory of illumination,
which made God present to the soul; its analogism,
which revealed an image of God and of His
attributes in each and every creature -- all of
these motives which, outside all speculation, speak
to us most vividly of what should be the ideal of
the Christian life.
It is understood, then, why Bonaventure is not
opposed to the doctrine of Aristotle, why he even
accepts it in part. But his preference is for St.
Augustine, and he again works out all the motives
of Augustinianism, in which all things, the
external and the internal world, matter and spirit,
speak to us of God; following Augustine he holds
that the apex of all human activity is
contemplation or mystical union with God.
In brief, Bonaventure shows the Christian what
kind of life he should live if he wishes to attain
his destiny. This is the historical function of the
mysticism of Bonaventure, which is as important in
the spiritual order as the Aristotelianism of
Thomas Aquinas in the order of rational
philosophy.
III.
Theory of Knowledge
Bonaventure admits three degrees of
knowledge:
- The first degree is knowledge of the
particular, of the individual. For this first
degree of knowledge, sensible experience,
corresponding to the physical senses, is
indispensable;
- The second degree consists in
knowledge of the universal, of ideas, and of all
that we acquire by reflecting upon ourselves.
This knowledge does not come from abstraction as
suggested by Aristotle and Aquinas, but from
illumination. This illumination is for
Bonaventure the result of an immediate
cooperation of God. The intellect needs this
cooperation or illumination in order to know the
intelligible.
- The third degree is the understanding
of things superior to ourselves -- God. This
kind of knowledge can be obtained through the
eye of contemplation. "The eye of contemplation
cannot function perfectly except in the state of
glory, which man loses through sin and recovers
through grace, faith and the understanding of
the Scriptures. By these the human mind is
purified, illumined, and brought to the
contemplation of heavenly things. These are
beyond the reach of fallen man unless he first
recognizes his own defects and darknesses. But
this he can only do by considering the fall of
human nature." (Breviloguium, II,
12.)
IV.
General Metaphysics
Bonaventure accepts the Aristotelian
principle of matter and form, but he wanders
far afield in the interpretation of both. Matter,
created by God, has its proper form, distinct from
all other forms or determinations which may come to
it. Moreover, it contains the seeds of all these
determinations (the doctrine of "rationes
seminales" of St. Augustine).
Nevertheless, it is an essential constituent of
every creature, even of those which are said to be
incorporeal, such as human souls and angels. The
matter of incorporeal substances, on account of the
form which it receives, is spiritual matter
("materia spiritualis"), which expresses what is
contingent and limited in every finite being.
Bonaventure admits in every body a plurality of
forms. Thus, besides the form which is proper to
the matter, in every body there are as many forms
as there are essential properties, all placed in
hierarchical order; that is, the inferior forms are
subordinate to the superior ones.
V.
Cosmology
In his cosmology, Bonaventure does not accept
the Aristotelian concepts of the eternity of the
world and of matter as co-eternal with God. The
world has its origin in the creative act in time;
creation "ab aeterno" is contradictory. God, who
has created matter, has placed in it the seeds or
reasons of all the determinations which it can
assume ("rationes seminales").
VI.
Psychology
In psychology, Bonaventure departs from
Aristotelianism not only in the fact of knowledge,
as we have already seen, but also in judging the
relationship between the soul and the body and
between the soul and its faculties.
For Bonaventure the soul is of its very nature
form and matter (spiritual matter), and as a
consequence is a complete substance, independent of
the body. The body in turn is composed of matter
and form (vegetative and sensitive form), but it
aspires to being informed by the rational form. In
this aspiration and coordination the unity of the
individual consists.
Without doubt, the unity of the person is not as
intimately welded as in Aristotelianism; but
Bonaventure's teaching avoids the danger into which
Aristotelianism entered with its theory of immanent
form, of making the soul dependent on the body even
in its destiny. Such a danger cannot exist in
Bonaventure, for whom the soul is a substance
complete in itself and not indissolubly united to
the body.
With regard to the faculties of the soul,
Bonaventure, in accord with St. Augustine,
distinguishes three -- the will, the understanding
and the intellective memory. For Bonaventure the
faculties are expressions of one and the same soul,
which is endowed with three diverse activities;
between the soul and its faculties there is merely
a logical distinction. In Aristotelianism the
faculties are qualities of the soul and really
distinct from it. Bonaventure holds that among the
faculties of the soul the will has primacy over the
other faculties; therefore it is necessary to love
in order to understand.
This law is applied also to our knowledge of
God: it is necessary to be united to God through
faith and grace in order to know Him and His
attributes. The process of this knowledge is
described in the Itinerarium mentis in Deum.
There are three grades or steps through which the
soul ascends to God.
- The first grade is called "vestigium," which
is the imprint of Himself that God has stamped
on material things outside ourselves.
- The second grade is "imago," or the
reflection of the soul upon itself, by which,
seeing the threefold faculties of the soul --
will, intellect, and memory -- man discerns the
image of God.
- The third grade is "similitudo," or the
consideration of God Himself. By considering the
idea of the most perfect being, we can conceive
the unity of God (the ontological
argument of Anselm, which Bonaventure admits
as valid); and from the concept of infinite
goodness we can reach the consideration of the
Trinity. In "similitudo" the soul attains to
mystical union, the supreme degree of love
between the creature and his Creator.
