The conventional view was that Phaedo presents four arguments for the soul's immortality, and I see no reason to doubt that Socrates believes them to be true. — Wayfarer
Correct. And nor must we forget that the dialogue's author is Plato who uses his Theory of Recollection to establish the validity of his Theory of Forms.
The basic argument from recollection is as follows:
(A). On seeing something that reminds us of something else, there is a case of recollection (
anamnesis) (Phaedo 73c – 74a).
(B). On seeing things that are equal, e.g., sticks, and thinking “these sticks are equal”, we intuitively think of Equality, i.e., the Form of Equal (Phaedo 74a – c).
(C). This cognitive act corresponds to the one described in (A), hence it is a case of recollection (74c – d).
(D.) As we can recollect only things that were previously known to us (73c), the Form of Equal was previously known to us (74d - 75a).
(E). But the knowledge of it was not acquired at any time between birth and the present act of recollection (75a - 76c).
(F). Nor was it acquired at birth (76c - d).
(G). Therefore it was acquired before birth (76c).
(H). Therefore our soul existed before birth, and possessed knowledge or wisdom, including knowledge of the Forms (76c).
It may of course be argued that what Socrates calls “recollection of Forms” is simply the result of pattern recognition produced by neural activity in the brain. However, research has shown that humans are capable of pattern recognition within days of being born and, to some extent, even whilst in the womb, which brings us very close to the concept of knowledge as a result of previous existence (see Ian Stevenson and others).
In any case, the existence of Forms remains a possibility, quite independently of pre-existence. Certainly, we know from Diotima’s teachings in the Symposium that the Form of the Beautiful does appear to the philosopher who has learned how to look at it.
In connection with learning how to see, Socrates in the Phaedo makes some important observations.
Through the use of our senses, we start regaining our lost knowledge of the Forms (75e).
In normal circumstances, the soul is dragged down into the world of material particulars whose ever-changing nature leaves it disturbed and giddy as if drunk (79c).
But when the soul is detached from the body and the material world, and is alone by itself, it perceives immaterial things that are pure, eternal, and immortal like itself (79d).
Therefore the true philosopher distances himself from the body and turns toward the soul (64e).
The philosopher releases his soul as much as possible from its association with the body (65a).
The Forms cannot be grasped through the bodily senses. Only those who train themselves most and with the greatest precision to think about each thing investigated as an object in its own right, will come closest to knowing each of them (65e).
The man who will hit upon reality is he who attempts to hunt down each real thing alone by itself and unalloyed, by using thought alone by itself and unalloyed, and separated as far as possible from eyes and ears and virtually from his entire body (66a).
To have pure knowledge of something we must be separated from the body and view things by themselves with the soul by itself (66e).
Full wisdom can only be acquired when we are dead because that is the only time when the soul will be alone by itself apart from the body (67a).
However (as philosophy is the practice of being dead, i.e., being detached from the body), we will be closest to knowledge even whilst living if we do not associate with the body except to the extent absolutely necessary, and we retain that state of purity until the God himself releases us (67b).
It can be seen that in order to acquire knowledge of the Forms, in addition to living a pure life, we need to detach ourselves from the body and sensory perception, and try to grasp reality first with our reason and then with our soul (
nous).
Detachment from the body, and focus on the soul and on a higher reality by means of our thought alone, and without the assistance of sensory perception, can only refer to a contemplative or meditative state.
So, without going into details, my feeling is that a Buddhist or Hindu may be in a better position to understand Plato than a Straussian atheist.
In any case, some key lessons to draw from the Phaedo are:
Philosophy = Separation from Body
Separation from Body = Death
Death = "Retreating" to or Rejoining the Intelligible World
The Intelligible World = The Realm of Eternal Realities like Soul and Forms
Knowledge of the Realm of Eternal Realities = Knowledge of Reality, including Forms
As already stated, additional pointers occur in other dialogues, such as Symposium:
“It neither comes to be nor perishes, neither waxes nor wanes … nor again will the beautiful appear to him [the philosopher] like a face or hands or any other portion of the body … or piece of knowledge … but itself by itself with itself existing for ever in singularity of form” (Symp. 211a ff.)
“In that state of life above all others, a man finds it truly worth while to live, as he contemplates essential Beauty […] there only will it befall him, as he sees the Beautiful through that which makes it visible, to breed not illusions but true examples of virtue, since his contact is not with illusion but with truth” (211d – 212a).
The Beautiful here stands for the Good or Truth itself and seeing the Good is identical with being with the Good and part of the Good. (As later Platonists would say, being one with the Good.)
Similarly, in the Republic we find the Analogy of the Sun where the Good is compared with the Sun (
508a ff.).
Here again, we can learn something from Strauss himself:
Plato never chooses an example at random. The example always means more than just an example … Let us not forget that the Sun is a cosmic God
- On Plato’s Symposium, pp. 201, 277
The analogy can only mean that the Good is a divine being like the Sun. We know that Plato’s theology has a hierarchy of divine beings proceeding from (1) the Gods of the City of Athens to (2) the Cosmic Gods like the Sun to (3) the Supreme God (the Good, the Creator of the Universe, the Universal Intelligence/Consciousness) who is the Ultimate Reality.
Come then, and join me in this further thought, and do not be surprised that those who have attained to this height are not willing to occupy themselves with the affairs of men, but their souls ever feel the upward urge and the yearning for that sojourn above. For this, I take it, is likely if in this point too the likeness of our image holds (Rep. 517c – d).
Where the Republic describes the hierarchy of sensible realities ascending from sensible objects to sight, light, and the source of light (the Sun) itself, and of intelligible realities ascending from intelligible objects to knowledge, truth, and their source (the Good), the Phaedo and the Symposium explain how the true philosopher may learn to obtain the vision of the highest.
In sum, quite aside from the arguments' ultimate validity, and considering that all Platonic
logoi can only be pointers, the dialogue certainly presents valuable advice for the philosophical and spiritual life.
