Basically, this is an introduction to (or maybe a synopsis of) Aristotle's Categories by the Neo-Platonist Porphyry. I just finished Aristotle's logical works, so that subject matter is still fresh enough in my mind that nothing here struck me as terribly novel or elucidative. That being said, this work was popular during the Middle Ages and some have found it helpful when reading Aristotle's categorical writings.

I am going through Porphyry's works at the moment, so I will save my comments regar

I rate this five stars not because it's original in any way but because it's a very clear explanation of a dense text. Porphyry is, like Aquinas, sometimes better at writing Aristotle than Aristotle is. Highly recommended to anyone struggling with Aristotle but who doesn't want to use boring contemporary secondary texts. Porphyry rocks (pun very much intended).

Invaluable introduction to Aristotle's works. I've been reading this along with others for a philosophy discussion group. We'll be starting on Aristotle's Categories next.

These are my notes on the passage. Unfortunately, OneNote doesn't transfer all of my notes nicely, and so certain parts have to be omitted.

Genus

Descriptio of Genus: that which is predicated essentially of many things differing in species.

Differs from property in that genus is predicated of many species, whereas property is predicated only one species and to the individuals belonging to that species.

Genus different from difference and common accident. Though difference and common accident may be

This interesting little treatise was intended as an introduction to the categories of Aristotle. Specifically, it is concerned with the hierarchical classification of different things; readers familiar with the biological concept of taxonomy (kingdom > phylum > class > order > family > genus > species) will recognize many of the basic concepts and terminology that remain in use to this day.

I've read some Aristotle in my day, but I'm certainly not an expert, and I'd be lying if

The best introduction to philosophy. This should be the first philosophy text students read. They should read Aristotle's Categories and On Interpretations second.

I read the translation by Octavius Freire Owen, M. A. of Christ Church, Oxford. It might as well be in the original greek. It served only to complicate things. I feel like it was begging for an illustrated version, or one in which hierarchy could be better illustrated, for the words were legible, but their combinations were not.

I get the usefulness of the document and its historical importance, but holy shit was this translation confusing.

I thought I said: this is a good introduction to Aristotelian logic. (The finishing date is approximate.)

Recommends it for: those stymied by Aristotle's works regarding logic

Excellent! If only I had known it exsisted before I tackled Aristotle's Prior and Posterior Analytics. It would have saved my hours of diagramming the structures of proper argument.

Porphyry's parents were Phoenician, and he was born in Tyre. His parents named him Malchus ("king") but his teacher in Athens, Cassius Longinus, gave him the name Porphyrius ("clad in purple"), possibly a reference to his Phoenician heritage, or a punning allusion to his name and the color of royal robes.

Porphyry of Tyre (Greek: Πορφύριος, Porphyrios, AD c. 234–c. 305) was a Neoplatonic philosophe
