The
Philosophy of
Plotinus
TABLE OF
CONTENTS
I.
Life
Plotinus (picture),
who brought forth the last great system of Greek
speculative philosophy, was born in Egypt. At the
age of thirty he came into contact with Ammonius
Saccas and immediately became his disciple; on
meeting the master, Plotinus exclaimed: "I have
found the man I need." He studied under Saccas for
ten years, that is, until the death of his teacher.
He then joined an expedition to the East under
Jordanus, and there obtained a knowledge of
Oriental religions. After the failure of the
expedition, Plotinus went to Rome, where he taught
for the next twenty years.
Plotinus was an ascetic and a meditative man,
and was reported to have twice reached the state of
ecstasy which he held to be the highest state of
life, and which defined as losing one's personality
and being united with God. Because of the religious
character of their philosophy, both he and his
pupils were considered as directors of souls and
spiritual fathers. During the last years of his
life, Plotinus retired to Campania, where he wished
to build a town of philosophers, to be called
"Platontown"; he died, however, before anything was
accomplished. Porphyry put Plotinus' books in order
(the Enneads) and wrote an account of his
life.
II.
General Notions
The problem: "What is man and what must he do to
reach happiness?" was not resolved by the Stoics
and Epicureans.
Plotinus tried to resolve this question by
overcoming dualism with monism.
God, according to
Plotinus, is not only the supreme inconceivable
reality but also the principle of all
realities. The invisible world as well
as the visible world, man included, is nothing
other than a derivation or emanation from God.
God is true happiness for
man; but as man cannot reach full knowledge of God
by reason, so also he cannot possess happiness of
himself; his intellectual knowledge is
not sufficient. Man needs a superior help in order
to reach God and to possess Him. This superior help
comes from God who, beyond all forces of reason,
manifests Himself to man, and makes him happy. This
what Plotinus calls "ecstasy": towards this
all his speculation points.
III.
Theory of Knowledge
Plotinus distinguishes four kinds of
knowledge:
- Sense
knowledge, which is an obscure
representation of truth;
- Reason
cognition, which gives us knowledge
of the essences of things;
- Intellectual
cognition, which gives us knowledge
of ourselves;
- Ecstasy,
which consists in a supernatural intuition of
God, in which our natural knowledge ceases in
the divine unconsciousness.
Plotinus offers a well-developed theory of
sensation. The objects of sensation are of a lower
order of being than the perceiving organism. The
inferior cannot act upon the superior. Hence
sensation is an activity of the
sensory agent upon its objects. Sensation provides
a direct, realistic perception of material things,
but, since they are ever-changing, such knowledge
is not valuable. In internal sense perception, the
imagination also functions actively, memory is
attributed to the imaginative power and it serves
not only in the recall of sensory images but also
in the retention of the verbal formulae in which
intellectual concepts are expressed. The human soul
can look either upward or downward; up to the
sphere of purer spirit, or down to the evil regions
of matter. Rational knowledge is a cognition of
intelligible realities, or Ideas in the realm of
Mind which is often referred to as Divine. The
climax of knowledge consists in an intuitive and
mystical union with the One; this is experienced by
few.
IV.
Metaphysics
The metaphysics of Plotinus may be considered in
two ways: as progression downward from God to the
world, i.e., the divine emanations; and upward from
the world to God, i.e., morality. Emanation is
marked by four degrees: matter, world soul, Nous,
and God or One. All the degrees of being partake of
the divinity, but in a different way (Monism). The
first three degrees: the world soul, Nous, and One,
form a sort of trinity, one that is impersonal,
attached to and dependent on the world.
a. One
The One (God) is the
principle of all knowledge, and all things are
dependent on Him. He has neither
material nor spiritual qualities; neither knowledge
nor will belong to Him. He
is above all understanding, and can be best
approached by negative theology. All we
can attribute to Him is "oneness" in
contrast to everything else, which implies
multiplicity. To sustain the absolute unity of God,
Plotinus was compelled to deny Him thought and
knowledge, for these operations suppose distinction
between subject and object, between thinker and
thoughts, and therefore imply multiplicity.
The universe proceeds from God not by free and
willing creation but by constant
emanation.
Through these emanations the "God-substance"
becomes common to all other degrees of reality
(Pantheism). God transcends the world, yet the
world-stuff is God-stuff. The emanations are the
Nous, the world soul, and nature. To explain the
emanations Plotinus compared them to the
superabundance of a flowing river, and a beam of
light. Just as a beam of light, as it goes farther
from its source, grows weaker and finally vanishes
into darkness, so it is with the emanations which,
after leaving the "One," lose their unity and
finally vanish into matter and evil.
b. Nous
The first emanation is the Nous; it is
intelligence, unchanged thoughts. The object of its
thoughts are three: the One, itself, and the ideas
which are in its spiritual nature. (This roughly
corresponds to the Ideal World of Plato.) The Nous
is inferior to the One, because multiplicity starts
with Nous -- i.e., there is a distinction between
the Nous and its thoughts.
c. World
Soul
The second emanation is the world soul. It
proceeds from the Nous as the Nous proceeds from
the One; it is therefore inferior to the Nous. The
world soul has two kinds of activities,
contemplative and plastic. Its act of contemplation
is beyond matter and time and its object is the
Nous. The plastic activity of the world soul
consists in forming the particular things of the
universe according to the ideas the world soul is
contemplating in the Nous.
d. The
Universe
The third emanation is the universe, i.e., the
sky, demons (good and evil spirits), human souls,
matter, and evil. The plastic forces of the world
soul inform the multiplicity of ideas in the
visible world. Thus particular souls originating in
the Nous come through the world soul into the
world; first, those souls that animate the sky;
second, those for the stars; third, those for
demons; and lastly, human souls, which fell down
into the world because of some mysterious sin.
Human souls, which were in a state of preexistence
in the Nous, are now imprisoned in the body. As in
the universal soul there are two activities,
contemplative and plastic, so also in each
individual soul (in the stars and in man) there are
two activities. In man these are the rational and
informative virtues; the rational, tending to the
formation of ideas, the informative, to the
informing of the body. Matter is the final step of
emanation; it is darkness and evil.
V.
Ethics
In Plotinus' theory of emanation the progress is
from God to the world; Plotinus' moral philosophy
is the reverse process or the return to God. Man is
able to make this return by means of purification
from matter (catharsis). Such a purification is
marked by three states: practical, contemplative
and ecstatic. Accordingly, there are three virtues
in man, ethical (practical), dianoetic
(theoretical), and ecstatic.
Ethical
Virtues: The ethical virtues are
practical and are concerned with and attached to
the world. They are not evil in themselves, but
there is always the danger that they might oppose
and rule the higher virtues in man. The practical
virtues, such as temperance, fortitude, prudence,
and justice, assure us of the practical domination
of the sensible world, and open the way toward the
operation of the superior contemplative
virtues.
Dianoetic
Virtues: The second grade of catharsis
or purification is marked by the function of
contemplative virtues ("dianoetic" being from the
Greek: "dia-noeomai -- I know throughout").
Plotinus divides these into aesthetic and rational
virtues. We know that in matter there are
intelligible ideas with which it is informed. If
these intelligibles are considered in regard to
their goodness or beauty, their residence is the
world soul. It is the function of the aesthetic
virtues to separate these intelligibles from matter
and to contemplate them as they exist in the world
soul, which is the residence of beauty. On the
other hand, if these intelligibles are considered
as truth, their residence is the Nous. It is the
function of the rational virtues to contemplate
as true, that is, as they exist in
the Nous, intelligible ideas separated from matter;
this is philosophy. Thus through the aesthetic
virtues our mind is united with the world soul, and
through the rational virtues it is united with the
Nous.
Ecstatic
Virtues: The ethical and dianoetic
virtues cannot lead us to absolute perfection,
which is the One. This can be done only through
ecstasy, the supreme degree of virtue. In the state
of ecstasy man remains passive and unconscious of
everything except his union with the One. This is
the supreme state of happiness for man. As in all
great systems in Greek philosophy, the theory of
knowledge in Plotinus corresponds to his theory of
being. As there are four degrees of emanation,
there are four degrees of knowledge: sensible,
rational, intellectual, and ecstatic. Sensible
knowledge (practical) deals with the world; it is
small and in darkness. The knowledge of reason is
discerning and deals with ideas and the essences of
things. Intellective knowledge is knowledge of
self, obtained through auto-contemplation. The
knowledge which crowns our mental activity is
ecstatic or knowledge of the One. It is acquired
not by virtue of the powers of the intellect but
through God.
Religion:
Plotinus placed God high above and transcending the
whole world and its activities; He can be known by
ecstasy alone. Between God and matter Plotinus
placed emanations, but in order to justify all
religions he also admitted intermediary demons or
spirits. His successor Porphyry arranged and
published Plotinus' works. Later Proclus and
Iamblichus developed the theory of demons and were
the advocates of a mysterious kind of knowledge
called gnosis.
