What I really want to hone in on is the actual logical method Aristotle uses when he is attempting ascertain and discern the "observed" nature of both slaves and masters. It's not really clear, I think, that he's using induction for this operation in method; no, I think he's defaulting to one of deduction, particularly where he recognized that both slaves and masters are "people," but then goes on to delineate that we can discern that one is not the same as the other and by what he thinks are "natural" inferences.
So you think that natural inferences cannot be inductive? I'm not sure why you think that. You may be mixing Hume with Aristotle. Aristotle is going to observe humans, both slaves and masters, and then produce arguments on the basis, and in favor, of his understanding of them. Same for most philosophers, actually. If you pick a paragraph from any philosopher and start asking questions about whether induction or deduction is occurring you can create false dilemmas. Authentic reasoning is always going to involve both induction (movement from the particular to the universal) and deduction (inferences based on at least one universal or categorical premise).
And if you are going to disagree with Aristotle you will be faced with your own dilemma: "inductive or deductive." How do you know human nature? How do you understand the nature of human beings? Do you disagree with Aristotle via inductive or deductive arguments?
For example, if we take one of Aristotle principles, "Every community is established with a view to some good," we can nitpick about how he arrived at such a universal principle. But unless one is a pure skeptic who does not believe in argument and knowledge, the principle must be treated as a knowledge claim that deserves consideration, just as his own principle claims deserve consideration. For Aristotle that principle is going to reduce to his psychological and ethical works, but for politics it is largely functioning as a premise.
I appreciate the sources, and I may look at them later. Keep in mind that I already have a number of sources describing Aristotle's thought, so it's not like I'm coming at this without my own sources for reference.
And you're welcome to bring some of those sources to bear on your points.
As for Groarke, I can't see how his thesis will displace the other appraisals of Aristotle we already have had for the last 450 years since Francis Bacon.
I do. The moderns were notoriously dismissive of Aristotle, mostly because he was tied up with late scholasticism. I don't know of Aristotelian scholars who think those appraisals are worth much. The paper quoted above, "The Nature and Origin of Ideas," is a good example of how far the era of Bacon was deviating from Aristotle, and how their novel ideas turned out to be less robust than was hoped, to say the least.
For me it's kind of like someone coming along and saying, "Hey, 2PhiloVoid! You need to let go of Jesus and go back to Moses ..." I know this analogy I'm giving isn't exact, but some aspects of what Groarke is proposing sort of sound this way from a "face value" level.
For me it's kind of like someone coming along and saying, "Hey Zippy! You need to let go of Jesus and update yourself with Immanuel Kant and religion within pure reason." I don't think newer is always better, and what are needed here are concrete arguments. If you think Aristotle's arguments against slavery show up his weak spots, then I expect that you will be able to explain why you think this. If you want a peek into a bit of that scholarship, then I would point you to, "
Aristotle's Defensible Defense of Slavery," written by the same Aristotelian scholar who wrote the other article, Peter Simpson. He belongs to the same school as Groarke regarding the nature of Aristotle's induction.
The reason I said, "...Or if you don't want to [engage Aristotle on slavery], then fine, whatever," is because slavery represents a presupposition and even taboo in our culture, such that we are prone to believe that "Any argument in favor of slavery must be a bad argument." For that reason one can do an extrinsic dismissal of Aristotle's arguments, "Aristotle argued for slavery, therefore he gave bad arguments (for slavery)." But of course this approach has nothing to do with a serious appraisal of Aristotle's arguments,
and that is in many ways the point at issue. We can perform extrinsic dismissals of Aristotle or the pre-moderns on the basis of what Lewis called chronological snobbery, but Templar and I don't accept this as a rational move. Note that it is this same sort of reasoning that justifies PH in his dismissal of, say, Paul where he has decided that Paul is outdated. A cavalier attitude towards ancient thinkers is the basic reason why no one takes religions seriously anymore, and for this reason I press people to try to actually engage ancient thought rather than simply dismiss it.
