36 - A Principled Stand: Aristotle's Epistemology

Posted on 5 June 2011

Peter discusses Aristotle's Posterior Analytics, asking what demands we must meet in order to count as having knowledge. The bar turns out to be set surprisingly high.

Aristotle's idea of persistent generalization seems to explain why he believed there was a static order in the animal kingdom. It could be said that his epistemics directly relate to his classification of the species according to type and binomial definition, right?

So, where was it that he wrote about what they coined "The Great Chain"? I'm interested to read that work.

Hi Luke,

Yes, you're exactly right about the relation of his biology and epistemology, that's one reason I tried to emphasize the point about the universality of knowledge (according to him).

The "great chain of being" idea is to me most familiar as the title of a book by Arthur Lovejoy. The basic idea is that there is a hierarchy of types of beings with God at the top, down through angels (or whatever), humans, animals, plants, minerals, and perhaps elements or matter itself at the bottom. Aristotle anticipates that to some extent, but doesn't use the expression I don't think.

Cheerio,

Peter

How interesting it is that Aristotle himself seems to be the root for our idea of an axiom.

Hi Peter thanks for your great podcasts! I am just wondering about the 'middle term'. In medicine, doctors are always trying to isolate and identify the causes of various diseases. So after experiment and trial and error they might find that the cause of disease X is Y, and so for example they found that the cause of TB was a particular kind of bacteria that spreads through the air (and not something in the water or something in the food etc). So could this be expressed as an Aristotelian or other kind of syllogism or is this just a different and non-syllogistic kind of cause?

Thank you

In reply to by Charles B

Hi -- that's an excellent example I think, actually, because Aristotle wants the middle term to be a causal link between the extreme terms. So the syllogism would go like this:

All flu sufferers are affected by the flu virus

All who are affected by the flu virus get symptoms X Y and Z

Therefore all flu sufferers get symptoms X Y and Z

So the idea would be that we started by observing that people have these symptoms and we look for the explanatory cause, which turns out to be the virus. It would be important for Aristotle that the same virus is always the cause, because these links for him are supposed to be necessary (so it couldn't be that sometimes the flu has some other underlying cause).

Might be worth thinking about this in the context of the medical epistemology debate I covered in this other episode. Basically I think the Empiricists would claim that the middle term isn't helping you do anything in terms of treatment -- just recognizing the symptoms is enough -- whereas the Rationalists would claim that it is integral to medicine that we discover the underlying cause.

Thanks,

Peter

Thank you Professor, again for this nice Episode! to keep it short here just my question: 

As you have linked the word "Science" from Latin sciencia from Knwoledge directly coming from the influence of Epistēmē, I wanted to ask if there is a possibility that we can also talk of an direct influence on this manner from Al Farbis Book: Ihsa' al-'Ulum (The Listing of the Sciences). Which is righfully tranlated as  "De scientiis" in Latin by Dominic Gundissalinus at around 1140. Where as in contrast, Boehtius and Hugh of St. Victor in his Book: "Didascalicon" (On the Studying of Reading) in the 1120's have a more Art like definition than Scientific Categories of these Principles. 

As always Thank you in advance!

Yunus Hueck 

Hi Yunus,

Definitely, yes. The Ihsa' was a major influence on late 12th and early to mid 13th century classifications of the sciences, I have been coming across lots of references to it in my reading on the 13th episodes which I'm writing at the moment. One should however bear in mind that the double meaning (science and knowledge) is also there in the Greek and so arguably this would have gotten into the Latin tradition no matter what via the translation of the Posterior Analytics.

Permapoesis 23 July 2017

Oh boy, I have so enjoyed this series, until now. Aristotle exempflies the problem of privilege in western culture. From philosopher to consumer we are prone to generating the greatest of pollutions. Go out and plant some corn, Aristotle, catch some fish, spend time with loved ones, your poesis stagnates with your non-oxygenating blood. The lonely male in his garret has done so much harm in the world. You need to walk further than around your Lyceum, go out, get out, away with you.

"Aristotle fails to see that happiness must be found solely in virtue, not physical well-being or in external circumstances; he denies the effective care of providence for human affairs, and so denies the value of prayer and man's answerability hereafter for his actions; he denies that the world is created; he denies the immortality of the soul. Excellent as a guide to terrestrial facts, he is a weak and blind guide on transcendental realities." (Chadwick, Early Christian Thought and the Classical Tradition, 109)
