It is hard to imagine improving on Aristotle without resorting to methods that were simply unavailable to him.
Just wanted to remind everyone that this is straight-up false. Aristotle assumed a lot of wrong things to prove also-wrong things. For example, Aristotle proved lots of stuff based on the infallibility of sensation, but since that’s a false premise, all that stuff was pointless. It’s not at all impossible to surpass historical figures, because not just believing what you like is fairly rare and gets rarer the further back in scientific progress you go.
The reason my criticism was bad is because it was unspecific—a mostly undeserved general impugning rather than noting a specific problem. Which is mostly because I don’t enough to point at a specific problem.
What exactly seems so bad about On The Soul? As I recall, it was about as reasonable a theory as anyone could have at the time. If I recall correctly, it basically identified the soul (i.e., whatever makes organisms capable of moving themselves) with how the physical parts of the body are organized. This certainly compares favorably to other pre-scientific theories, such that the soul is a nonphysical spiritual entity (as Christians believe), or a cloud of special soul particles (as the Greek atomists taught), or some mysterious élan vital (as many pre-20th century biologists held).
Well, I’d agree that it’s much better than élan vital. And as I’m reading it because of this discussion, it really isn’t about the modern conception of souls—“de anima” here is more like “on the essence of animals.” But there are plenty of individual wrong conclusions, where one could “improve on Aristotle without resorting to methods that were simply unavailable to him.” Skimming through book 3, we get stuff like this:
That there is no sixth sense in addition to the five enumerated-sight, hearing, smell, taste, touch-may be established by the following considerations:
-
Therefore, since everything is a possible object of thought, mind in order, as Anaxagoras says, to dominate, that is, to know, must be pure from all admixture; for the co-presence of what is alien to its nature is a hindrance and a block: it follows that it too, like the sensitive part, can have no nature of its own, other than that of having a certain capacity. Thus that in the soul which is called mind (by mind I mean that whereby the soul thinks and judges) is, before it thinks, not actually any real thing. For this reason it cannot reasonably be regarded as blended with the body: if so, it would acquire some quality, e.g. warmth or cold, or even have an organ like the sensitive faculty: as it is, it has none.
-
the soul is in a way all existing things; for existing things are either sensible or thinkable, and knowledge is in a way what is knowable, and sensation is in a way what is sensible
(“in a way” here meaning that like is required to sense like, and like is required to recognize like thoughts. So, false)
-
An animal is a body with soul in it: every body is tangible, i.e. perceptible by touch; hence necessarily, if an animal is to survive, its body must have tactual sensation.

Okay, I think that’s enough. So I do now feel that De Anima is better than I’d represented it as, but it invents models more complicated than justified, and so gets some wrong conclusions, which could have been avoided if stuff had not been made up.
For example, Aristotle proved lots of stuff based on the infallibility of sensation, but since that’s a false premise, all that stuff was pointless.
Could you direct me to where Aristotle asserts that data from the senses are infallible? If I remember correctly, Aristotle defended a kind of virtue epistemology where sense data could only be trusted under very strict conditions and by someone virtuous enough (in rationality) to interpret the experiences correctly.

I don’t know much about Aristotle, but this claim sounds to me like a distortion of something Aristotle might have said.
Hm, well, after a little looking into it I think my criticism wasn’t the best characterization ever, but not entirely unfounded.

So, what is particularly bad about the arguments in Aristotle’s On the Soul?

The infallibility of the senses sounds more like Rand.
