You have not provided any support for this claim. — Paine
As I said, I provided the support in an in depth way in the other thread, and outlined it in my last post. That book is clearly inconsistent with works of Aristotle which are well known to have been produced by him. And, since it is also known that the books under the title "Metaphysics" were teachings collected together in Aristotle's school, many years after his death The conclusion that this particular section was not actually his work is justified, in that way.
Regardless though, the point is that this section of "Metaphysics" is inconsistent with other parts of Aristotle's work. This could be a feature of a changing mind of the writer, like we find in Plato. So Plato's works are carefully ordered chronologically, and his thoughts are divided into distinct periods. In the case of Aristotle, we'd have to put that section of "Metaphysics" near the beginning of the order, because we see how he produces arguments to refute those ideas. He would not conclude this after refuting it, but he might propose it prior to refuting it. This is similar to the way that Plato produces arguments which refute the theory of participation, so the dialogues which support participation are presented as earlier. Instead, though, that book Lambda is placed at the end of "Metaphysics", as if it's Aristotle's final conclusion. As I showed in the other thread, and outlined in my last post, he actually moves to refute it those ideas.
In a separate comment, I will list all the places I know of where Aristotle alludes to a separate, independent intellect. I don't have time to run them all down until can get back to my books next week. — Paine
Yes, I remember you brought up a number of mentions of an independent intellect. I agree that with respect to "the intellect" there is obvious inconsistency in Aristotle. And this is an issue which has always been a problem. It is very evident in the Scholastics, manifesting as the division between the active intellect and the passive intellect. The desire to have as a principle, a separate, independent intellect, led to the notion of a complete separation between active and passive intellect. This allows that the active intellect might be free from the influence of the passive matter (potential), allowing the intellect the capacity to know all things.
This is a clear problem, because what Aquinas presents, is that the human intellect is deficient, being dependent on the material body. So Aquinas proposes that the intellect might only adequately know things like God, after separation from the body.
But a completely separate, active intellect appears to be impossible by Aristotle's principles. This is because the intellect in each of its capacities, the capacity to know, prior to learning, and the capacity to act, posterior to learning, are all properly described as potentials. This led Aquinas to assume a potential which is not properly material, to account for the desire to portray a separate, active intellect, unbound by matter.
I do not accept this resolution, because it introduces two distinct types of "potential", and distinctions of type are formal. This distinction of types of potential would put fundamental forms as inherent within matter, instead of allowing for the reality of true separate Forms. But if we allow for true separate Forms, as Aquinas surely wanted to do, with God and the angels, then these Forms (form being actual) cannot be a sort of intellect, because intellect is fundamentally a potential.
The need to conclude separate Forms is produced by the cosmological argument, BK.9 of "Metaphysics". The separate Forms account for the actuality which is necessarily prior to potential, in the absolute sense. If we adhere to what Aristotle discusses in Bk 1, Ch.3 of "De Anima", we see that the separate Forms must be truly immaterial, and cannot be described in material representations like eternal circular motions. Further, the thinking on thinking representation is said to be improper as well, because it does not accurately represent thinking. And, it is later shown how thinking as the act of an intellect is fundamentally a potential, therefore it cannot be used to represent a pure, independent actuality.
So here we find the fundamental inconsistency of Neo-Platonism, specifically Plotinus. We see "the One" as the first, and most fundamental principle. But the One is supposed to be both pure, absolute potential, as well as the first cause, from which all proceeds. But pure, absolute potential cannot be a cause, because it lacks any actuality, as explained in "Metaphysics" Bk.9, the cosmological argument. This argument by Aristotle effectively refutes both materialism (having matter as the first principle), and Pythagorean Idealism (having ideas as the first principle), by classifying both as potential. "Matter" may then be understood as an idea, and ideas are potential. This leaves the aspect of reality which is supposed to correspond to "matter" as something unintelligible, and opens the door to matter based mysticism. Neo-Platonism mistakenly adhered to principles of Pythagorean Idealism which had been refuted by Plato and Aristotle, in a bid to ward off material mysticism.
But I will restate the problem I had with your comment the first time around. You are using a certain set of texts to establish your interpretation of what Aristotle means to say. On the basis of that, you declare Aristotle is not consistent with his own principles when he refers to an active, separate intellect. Whatever explanation might be put forward for the conflict of principles, it is always logically possible that the inconsistency belongs to your interpretation. — Paine
Actually, I refer to a wide variety of material, as indicated above. Chiefly, Aquinas provide a very good presentation of these interpretive problems, because they had become exposed by the Scholastics. Appollodorus accused me of reading Plato through Aristotle, and Aristotle through Aquinas, instead of interpreting the person directly. The problem being that Appollo took this as a fault, when really these are the people who put much effort into solving the puzzles put forward by the philosophers before themselves. So it doesn't work, as a criticism, to accuse me of an idiosyncratic interpretation, and also accuse me of reading one philosopher through the mind of another, as Appollo did.
Outside of its description in Book Lamba, it should be noted that many of the other books of the Metaphysics try to see how and if the introduction of composite beings relate to the method in the Categories. There is much scholarly debate on these topics and disagreement about which statements are consistent with other statements. The statement in Book Lambda: "the soul is the first substance" is a part of that conversation even if you dismiss the rest of the book as Neo-Platonists propaganda. — Paine
The fundamental issue of the "Metaphysics" is, I would say, what Aristotle lays out around BK 3, I think. The question is why is a thing what it is. He dismisses often cited question of why is there something rather than nothing, as unanswerable, and therefore misleading, so he proceeds to the more relevant question of why is any particular thing, the thing which it is. Primary substance according to "Categories" is an individual, a particular, and now, the particular must have an identity by the law of identity.
He points to the following logical argument. A thing must be the thing which it is, by the law of identity. And, when a thing comes into being, it must necessarily come into being as the thing which it is or else a thing could be other than the thing which it is, in violation of the law of identity. It is impossible that the self-same thing could be two distinct things at the same time. Therefore we can conclude that the form of the thing, as "what the thing is" is temporally prior to the existence of the material thing, as the cause of the thing being what it is, rather than something else, when the thing comes into existence. Otherwise a thing would be a random collection of parts, but it is not, it has an orderly form. When taken in the absolute sense, as the cosmological argument (Bk 9), we see that there must be an immaterial Form, prior to all material existence.
Around BK 6, Aristotle questions where the form of the thing comes from. He distinguishes between natural things and artificial things, and provides an in depth description of artificial things. The form of the thing comes from the soul of the artist. This is important, because we see that the form, of what the thing will be, when the thing comes into existence, does not inhere within the matter itself, but comes from some other source. Then he leads us toward the conclusion that there is a very similar situation in natural things. So we must assume separate independent Forms, according to the principle that the form does not come from within the matter.
The issue you point to. "the soul is the first substance", needs clarification. Primary substance is a particular individual, which by Aristotle is a composition of matter and form (hylomorphism). The soul, by "De Anima", is a form, the first form of a body having life potential in it, so we can understand it in the sense of an independent Form, described above, being the cause for the material body coming into being as the body which it is, rather than something else. But it's doubtful whether it is correct to call such a Form a substance, because it doesn't fit into Aristotle's definition of "substance" in "Categories", either in the primary or secondary sense.
When that possibility is not taken seriously the whole of the text or texts may be distorted in order to accomodate an interpretation. That is just bad hermeneutic practice. I follow the advise of those who say that when there is an apparent contradiction look to see if it is or can be reconciled based on further consideration and closer examination. — Fooloso4
More often than not, what is the case is that the inconsistency gets overlooked, it goes undetected by the readers, because each reader interprets in one's own way, ignoring the parts which don't really make sense. However, it manifests later in discrepancies between various interpretations. The inconsistencies in Plato produced discrepancies between Neo-Platonism and Aristotle, for example. And the inconsistencies in Aristotle manifest in the problems which the Scholastics confronted.
So the bad hermeneutic practice is actually the opposite of what you say it is. To attribute the appearance of inconsistency to a deficiency in the skill of the reader, rather than to a deficiency in the skill of the writer is the wrong approach. This is because inconsistency in philosophy is common and pervasive due to the complicated, complex, and unexplored subject matter. Philosophy ventures into the unknown. If we assume the the appearance of inconsistency is a deficiency in reading skills, when the inconsistency is real, and within the material, due to a deficient understanding of the writer, we will either get bogged down in our attempts to understand, never being able to understand inconsistent material, or we'll have to ignore relevant material, and then we'll get bogged down in discussing who's interpretation is the correct one.
Therefore the appropriate procedure is to proceed with a healthy respect for the likelihood of inconsistency in the material, and with a mind open to the reality that the writer most likely did not have a complete understanding of the material. Remember, what is being sought is the truth concerning the subject, not the truth as to what so and so said about the subject. This leaves us in a position to accept whatever an author says, which appears to be consistent with the truth, and reject whatever one says which appears to be inconsistent with the truth. Looking for the truth as to what so and so said will be a fruitless effort because the reality of ambiguity renders this as an impossible ideal.
