Cousin,) but makes difference, property, and accident to be all predicated Moreover, property is inherent in the whole species, of which it is the property, in it alone, and always, but genus in the whole species indeed of which it is the genus, and always, yet not in it alone; once more, properties being subverted do not co-subvert genera, but genera being subverted, co-subvert species, to which properties belong; wherefore, also those things of which there are properties, being subverted, the properties themselves also, are co-subverted.

Also it is common to both to be always present, and to every one, for though a biped should be mutilated, yet (the term biped) is always predicated with reference to what is naturally adapted, since also risible has the "always" from natural adaptation, but not from always laughing. Commonly the word Again, species subsists prior to property, but property accedes to species, for man must exist, in order that risible may: besides, species is always present in energy with its subject, but property sometimes also in capacity, for Socrates is a man always in energy, but he does not always laugh, though he is always naturally adapted to be risible. |617 genus of the species will also be necessarily predicated, also that genus of the genus up to the most generic; for if it is true to say that Socrates is a man, but man an animal, and animal substance, it is also true to say that Socrates is animal and substance. Isagoge AbeBooks. According then, to the differences which produce another thing do the divisions of genera into species arise, and the definitions arising from genus and such differences are assigned. 23. XI. The scholastic classification, obtained from Boëthius's version of the Isagoge, modified Aristotle's by substituting differentia (diaphora) and species (eidos) for definition (horos). xlviii. Now it is common to them all to be predicated, as we have said, of many things, but genus (is predicated) of the species and individuals under it, and difference in like manner; but species, of the individuals under it; and property, both of the species, of which it is the property, and of the individuals under that species; again, accident (is predicated) both of species, and individuals. Cf. It remains to speak of property and accident, for how property differs from species, difference, and 33, 34. Since then, there are three species of difference considered, some indeed separable, but others inseparable, again, of the inseparable, some are per se, but others accidental, moreover of differences per se, some are those according to which we divide genera into species, but others according to which the things divided become specific:--thus of all such differences per se of animal as these, animated and sensitive, rational and irrational, mortal and. Nevertheless, such is not the case, but always those successive being enumerated, and two being deficient by one difference, from having been already assumed, and the three by two differences, the four by three, the five by four; all the differences are ten, namely, four, three, two, one.

He adds also, that the difference is not always one quality, but is frequently compounded of several together, no one of which would alone suffice." opera. This text was transcribed by Roger Pearse, Ipswich, UK, Again, of species the participation is equal, but of accident, even if it be inseparable, it is not equal; for an Ethiopian may have a colour intense, or remitted, according to blackness, with reference to an(other) Ethiopian. Again, we declared how species differs from difference, when we showed how difference differs from species; also we showed how species differs from genus, when we explained how genus differs from species; what remains then, viz.

Now genus is such as "animal," species as "man," difference as " rational," property as " risible," accident as "white," "black," "to sit." --Of Community and Difference of Species and ch. In descending then, to the most specific, it is necessary to proceed by division through multitude, but in ascending to the most generic, we must collect multitude into one, for species is collective of the many into one nature, and genus yet more so; but particulars and singulars, on the contrary, always divide the one into multitude, for by the participation of species, many men become one man; but in particulars and singulars, the one, and what is common, becomes many; for the singular is always divisive, but what is common is collective and reductive to one.13. --Of Community and Difference of Genus and Property. From property, moreover, genus differs because property is predicated of one species alone of which it is the property, and of the individuals under the species, as "risible" of man alone, and of men particularly, for genus is not predicated of one species, but of many things, which are also different in species. 1 For the exemplification of the above, see the "Arbor Porphyriana," (sometimes called by the Greek logicians, the "ladder," So many then are the points common and peculiar to difference and the others.

Thus, Agamemnon is Atrides, Pelopides, Tantalides, and lastly, (the son) of Jupiter, yet in genealogies they refer generally to one origin, for instance, to Jupiter; but this is not the case in genera and species, since being is not the common genus of all things, nor, as Aristotle says, are all things of the same genus with respect to one summum genus. VI. Neither genus nor species appear to be simply denominated, for that is called genus which is a collection of certain things, subsisting in a certain respect relatively to one thing, and to each other, according to which signification the genus of the kind of a thing it is. XIV.--Of Community and Difference of Accident and Difference. 1. ἐϝ τῷ ὁποῖόν τὶ ἐστιν: Boethius distinguishes quale in substantia, from quale non in substantia. The definition here given of difference, as to its being the excess of species over genus, is clear, from a reference to what was stated in the last note of the preceding chapter. Log. Summa, p. 1; Qu. It is common then to difference and species to be equally participated, for particular men partake equally of man, and of the difference of rational. For animal is divided by the difference of rational and irrational, and again, by the difference of mortal and immortal; but the differences of rational and mortal are constitutive of man, but those of rational and immortal of God, those again, of mortal and irrational, of irrational animals.17 Thus also, since the differences of animate and inanimate, sensitive and void of sense, divide the highest substance, animate and sensitive added to substance, complete animal, but animate and deprived of sense, form plant; since then, the same  Yet the media will be the species of such as are before them, but the genera of things after them, so that these have two conditions, one as to things prior to them, according to which they are said to be their species, the other to things after |622 man, in the same manner as the statue there. Concerning genus then, and species, we have shown what is the most generic, and the most specific, also what the same things are genera and species, what also are individuals, and in how many ways genus and species are taken. They also define it thus; accident is that which may be present and not present to the same thing; Moreover, because it is predicated in reply to what a thing is, it is distinguished from differences and from accidents commonly, which are severally predicated of what they are predicated, not in reply to what a thing is, but what kind of a thing it is, or in what manner it subsists: the description therefore of the conception of genus, which has been enunciated, contains nothing superfluous, nothing deficient.8, Species indeed is predicated of every form, according to which it is said, "form is first worthy of imperial sway;"9 still that is called species also, which is under the genus stated, according to which we are accustomed to call man a species of animal, animal being genus, but white a species of colour, and triangle of figure.

For in reply to the question, what kind of a thing man is, we say, that he is rational, and in answer to what kind of a thing a crow is, we say that it is black, yet It is common then to property and inseparable accident not to subsist without those things in which they are beheld, for as man does not subsist without risible,25 so neither can Ethiopian subsist without blackness, and as property is present to every, and always, so also is inseparable accident. 1 Ammonius remarks that, "It is worth while to doubt why Porphyry says that the first signification of genus appears to be the one easily adopted, and not the second signification, which is the habitude of one thing to one; since this nature first knows, for she first produces one thing from one, and thus many from many." Nevertheless, they differ, in that property is present to one species alone, as the being risible to man, but inseparable accident, as black, is present not only to an Ethiopian, but also to a crow, to a coal, to ebony, and to certain other things. --Of Community and Difference of Genus and Species.

II.--Of the Nature of Genus and Species. From such things then, as are predicated of one thing only, genera differ in that they are predicated of many, but on the other hand, from those which are predicated of many and from species, (they differ) because those species are predicated of many things, yet not of those which differ in species, but in number only, for man being a species, is predicated of Socrates and Plato, who do not differ from each other in species, but in number, while animal being a genus is predicated of man, and ox, and horse, which differ also in species from each other, and not in number only. On the other hand, as to those which only make a thing different in quality, diversities alone consist, and the changes of XVII.-- Of Community and Difference of Property and Accident. Accident is that which is present and absent without the destruction of its subject. Still, of these, substance is the most generic, and that which alone is genus; but man is most specific, and that which alone is species; yet body is a species of substance, but a genus of animated body, also animated body is a species of body, but a genus of animal; again, animal is a species of animated body, but a genus of rational animal, and rational animal is a species of animal, but a genus of man, and man is a species of rational animal, but is no longer the genus of particular men, but is species only, and every thing prior to individuals being proximately predicated of them, will be species only, and no longer genus also. Difference also and property have it in common to be equally shared by their participants, for rational are equally rational, and risible (equally) risible (animals). On the Cave of the Nymphs in the Odyssey (De Antro Nympharum) includes Porphyry’s allegorical interpretation of Homer’s Odyssey 13.102-112. Philoponus, in his extracts from Ammonius, illustrates this as follows: Let a seal-ring be conceived, having the image of Achilles upon it, from which seal let there be many impressions taken in pieces of wax, afterwards let a man perceiving the pieces of wax to have all the impression of one seal, retain such impression in his mind: then the seal in the ring is said to be prior to the many; the impression in the wax to be in the many, and the image remaining in the conception of the spectator, after the many, and of posterior origin.

Besides, difference indeed docs not admit of intension and remission, but accidents accept the more and less; moreover contrary differences cannot be mingled, but contrary accidents may sometimes be mingled. 1  At the request of Chrysaorius, his pupil, who had recently met with the Categories of Aristotle, Porphyry wrote this introduction, in order to his comprehension of that treatise: nearly the whole of it is composed from the writings, and often almost in the very words of Plato. 2   Dialectic, according to Plato, consists of four parts, division, definition, demonstration, and analysis; hence a treatise adapted to the formation of these, will be evidently useful to the dialectic of Plato. 2. pp.609-633. note; Crakanthorpe, Log.

If physical, do they have a separate existence from physical bodies, or are they part of them? subsistence of a thing; beginning then, again, from the first, we must say that of differences some are separable, others inseparable, thus to be moved, and to be at rest, to be ill, and to be well, and such as resemble these, are separable, but to have a crooked, or a flat nose, to be rational, or irrational, are inseparable differences. We have shown then, wherein genus differs from the other four, but each of the other four happens also to differ from the rest, so that as there are five, and each one of the four differs from the rest, the five being four times (taken), all the differences would appear to be twenty. The agreement between the first and last, proves that there is no real difference between nominalism and conceptualism, since they were both. The first genus, moreover, is so called, which is the principle of each man's generation, but afterwards the number of those who are from one principle, e. g. from Hercules, which defining and separating from others, we call the whole collected multitude the genus of the Heraclidse. and this by Porphyry will appear, upon which see Mansel's comment.

They assign, therefore, species thus: species is what is arranged under genus, and of which genus is predicated in reply to what a thing is: moreover, thus species is what is predicated of many things differing in number, in reply to what a thing is. As then, genus is predicated triply, the consideration by philosophers is concerning the third, which also they explain by description, when they say that genus is that which is predicated of many things differing in species, in answer to what a thing is, e. g. irrational, as animal does, yet it comprehends man and divinity, which are species. 18. p. 1, Albertus Magnus, Abelard. Chap. As then, substance being in the highest place, is most generic, from there being no genus prior to it, so also man being a species, after which there is no other species, nor any thing capable of division into species, but individuals, (for Socrates, Plato, Alcibiades, and this white thing, I call individual,) will be species alone, and the last species, and as we say the most specific.

Aquinas first removed the genus animal rationale from the Arbor Porphy., and limited rationality to man, distinguishing angels as intellectuales.

Albert de Predicab. It is also common always to be present to their participants, for Socrates is always rational, and always man, but it is the property of difference indeed to be predicated in respect to what kind a thing is of, but of species in respect to what a thing is, for though man should be assumed as a certain kind of thing, yet he will not be simply so, but in as far as differences according to genus constitute him. On the other hand, the most specific they place in a certain number, yet not in an infinite one, but individuals which are after the most specific are infinite; wherefore, when we have come down to the most specific from the most generic, Plato exhorts us to rest,12 but to descend through those things which are in the middle, dividing by specific differences; he tells us however to leave infinites alone, as there cannot be science of these. Hence, those which render it another thing are called specific, but those, In the Aristotelian definition of man, Porphyry is best known for his contributions to philosophy. As moreover, rational is difference, the use of reason is predicated of it, as of difference, yet the use of reason will not be predicated of rational only, but also of the species under rational. Yet more, genus is predicated in reference to what a thing is, but difference in reference to what kind of a thing it is, as was observed before; besides there is one genus according to every species; e. g. of man, animal (is the genus), but there are many differences, as rational, mortal, capable of intellect and science, by which he differs from other animals. Porphyry, ca. |621 differences taken in one way become constitutive, but in another divisive, they are all called specific. 4, Isagog. --Of Things common and peculiar to the Five Predicates.

For since things consist of matter and form, or have a constitution analogous to matter and form, as a statue is composed of brass, matter, but of figure, form, so also man, both common and specific, consists of matter analogous to genus, and of form analogous to difference, but the whole of this, animal, rational, mortal, is 2  Cf.

They say also that these are validly properties, because they reciprocate, since if any thing be a horse it is capable of neighing, and if any thing be capable of neighing it is a horse. As an introduction to Aristotelian logic, therefore logic, it, along with Porphyry's Isagoge, is pretty good if not from the horse's mouth but through neo-platonist philosophical teeth mouthing Aristotle to make it compatible with Plato, as is apparently the bounden duty of the neo-platonists from AD 200 - 600 in 15,000 pages! 1 "Rationales enim sumus et nos et Dii," vetus interpres Latinus.

For it is necessary that either equals should be predicated of equals, as neighing of a horse, or that the greater should be predicated of the less, as animal of man, but the less no longer of the greater, for you can no longer say that animal is man, as you can say that man is animal.

Abelard de Gen. et Spec. by Henry G. Bohn in London in 1853. Many writers, such as Boethius himself, Averroes, Abelard, Scotus, wrote commentaries on the book. Again, after another manner also, the principle of the generation of every one is called genus, whether from the generator or from the place in which a person is generated, for thus we say that Orestes had his genus from Tantalus, Hyllus from Hercules, and again, that Pindar was by genus a Theban, but Plato an Athenian, for country is a certain principle of each man's generation, in the same manner as a father. 20 are rational, but the addition of mortal separates us from them. |619 which make it different in quality, are simply They also co-subvert, but are not co-subverted, for species existing, genus also entirely exists, but genus existing there is not altogether species; genera too, are indeed univocally predicated of species under them, but not species of genera. Elem. Would you like Wikipedia to always look as professional and up-to-date? When however we are asked what man is, we answer, an animal, but animal is the genus of man, so that from genus being predicated of many, it is diverse from individuals which are predicated of one thing only, but from being predicated of things different in species, it is distinguished from such as are predicated as species or as properties. 1   Boethius agrees with Porphyry, that accidents, properly so called, are useless in definition, (vide Opera, p. 3,) accidental definition is, in fact, merely a description. Between the most generic and the most special, there are others which are alike both genera and species, referred, nevertheless, to different things, but what is stated may become clear in one category. porphyry isagoge. Now, what we have stated will be evident in this way: in each category there are certain things most generic, and again, others most special, and between the most generic and the most special, others which are alike called both genera and species, but the most generic is that above which there cannot be another superior genus, and the most special that below which there cannot be another inferior species. [1], The Introduction was translated into Arabic by Ibn al-Muqaffa‘ from a Syriac version. |620 for neither is genus more and less predicated of that of which it is the genus, nor the differences of genus according to which it is divided. Other writers such as William of Ockham incorporated them into their textbooks on logic. Moreover, property is reciprocally predicated of that of which it is the property, and is equally (present), but inseparable accident is not reciprocally predicated, besides, the participation of properties is equal, but of accidents one (subject partakes) more, but another less. Those too, which are per se, do not admit of the more and less, but the accidental, even if they be inseparable, admit of intention and remission, --Of Community and Difference of Accident and Difference. Also genus indeed is predicated of many species, but property of one certain species of which it is the property. Now, it is the property of genus to be predicated of more things than difference, species, property, and accident are, for animal (is predicated) of man and horse, bird and snake, but quadruped of animals alone, which have four feet; again, man of individuals alone, and capacity of neighing of horse alone, and of particulars. For animal being subverted, rational and irrational are co-subverted, but differences no longer co-subvert genus, for even if all of them should be subverted, yet we may form a conception of animated, sensible substance, which is animal. Vide also Huyshe's Log., pp. Moreover, one is most properly said to differ from another, when it varies by specific difference, as man differs from horse by specific difference, i. e. by the quality of rational. 2 and 3. isagoge (plural isagoges) An introduction, especially (particularly capitalized) Porphyry's introduction to the works of Aristotle.

Congratulations on this excellent venture… what a great idea! Again, they define it (difference) also thus: difference is that which is predicated of many things differing in species in answer to the question, of what kind a thing is,19 for rational and mortal being predicated of man, are spoken in reply to what kind of thing man is, and not as to the question what is he. --Of the Community and Distinction of Genus and Difference. The difference between the dialectic of Plato and that of Aristotle, is noticed in the subsequent notes upon the Organon, and the reader will find the subject ably discussed in the introduction to Mansel's Logic; here we need only observe that Aristotle in the Topics, looks to opinion (in his treatment of dialectic), while Plato disregards it, and the former delivers many arguments about one problem, but the latter, the same method about many problems. 5. Now, it is the property of difference, that it is frequently predicated of many species, as rational of divinity and man, but property (is predicated) of one species, of which it is the property. For to be naturally adapted to sail is not the difference, though it is the property of man, since we may say that of animals, some are naturally adapted to sail, but others not, separating man from other animals; yet a natural ability to sail does not complete the essence, neither is a part of it, but only an aptitude of it, because it is not such a difference as those which are called specific differences. be relatively considered as a highest genus. --Of Community and Difference of Species and Property.

Since it is necessary, Chrysaorius, both to the doctrine of Aristotle's Categories, to know what genus, difference, species, property, and accident are, and also to the assignments of definitions, in short, since the investigation of these is useful for those things which belong to division and demonstration,2 I will endeavour by a summary briefly to discuss to you, as in the form of introduction, what on this subject has been delivered by the ancients, abstaining, indeed, from more profound questions, yet directing attention in a fitting manner, to such as are more simple.

Besides, genus differs from difference and from accidents in common, because though differences and accidents in common are predicated of many things, different also in species, yet they are not so in reply to what a thing is, but (what Difference. Sophroniscus, if Socrates alone is his son, and such things are called individuals, because each consists of properties of which the combination can never be the same in any other, for the properties of Socrates can never be the same in any other particular person;15 the properties of man indeed, (I mean of him as common,) may be the same in many, or rather in all particular men, so far as they are men.

Notwithstanding, it is pre-eminently (predicated) of individuals, but secondarily of those things which comprehend individuals. For in what genus differs from difference, species, property, and accident, we have shown, wherefore, there are four differences; also we explained in what respect Genus and species possess in common, (as we have said,) the being predicated of many things, but species must be taken as species only, and not as genus, if the same thing be both species and genus. It is also common (to them) to be equally present, for species are equally present to their participants, and properties to the things of which they are properties, but species differs from property, in that species indeed may be the genus of other things, but property cannot possibly be the property of other things. 1   Risibility is considered to be so dependent upon rationality, as that the latter could not exist without the former, and if this were not so, the term risible would not be a property of man, but only an inseparable accident. 3; Opusc. de Predicab. Porphyry philosopher. 1  The property of a subaltern genus is predicated of all the species comprehended in that genus; that of a lowest species is predicated of all the individuals which partake of the nature of that species: thus, "Shape is the generic property of body,  The Isagoge (Greek: Εἰσαγωγή, Eisagōgḗ) or "Introduction" to Aristotle's "Categories", written by Porphyry in Greek and translated into Latin by Boethius, was the standard textbook on logic for at least a millennium after his death. 5, of the Categories, with the note. Moreover, genus comprehends difference in capacity, for of animal one kind is rational, but another irrational, but differences do not comprehend genera. --Of Community and Difference of Species and Accident. 27. 3  Viz. species |618 both a whole and a part; part indeed of something else, but a whole not of another, but in other things, for the whole is in its parts.

Besides property is reciprocally predicated of that of which it is the property, but genus is not reciprocally predicated of any thing, for neither if any thing is an animal, is it a man, nor if a thing be animal is it risible, but if any thing is a man it is risible, and vice versa. Cf. In medieval textbooks, the all-important Arbor porphyriana ("Porphyrian Tree") illustrates his logical classification of substance. Portland]. Though he did not mention the problem further, his formulation constitutes the most influential part of his work, since it was these questions that formed the basis of medieval debates about the status of universals. 2007. IX. It receives a two-fold division, for one kind of it is separable, but the other inseparable, e. g. to sleep is a separable accident, but to be black happens inseparably to a crow and an Ethiopian; we may possibly indeed conceive a white crow, and an Ethiopian casting his colour, without destruction of the subject. and Mansel's Prolegomena Logica. The five heads of predicables therefore, taken from this Isagoge, which was written in the third century, are an addition to the Aristotelian Logic, in part of which, (the Topics,) the doctrine laid down differs from that enunciated here, in several points, as Porphyry's view also differs from that of Aldrich.
