Applied ontologies have been used more and more frequently to enhance systems engineering. In this paper, we argue that adopting principles of ontological realism can increase the benefits that ontologies have already been shown to provide to the systems engineering process. Moreover, adopting Basic Formal Ontology (BFO), an ISO standard for top-level ontologies from which more domain specific ontologies are constructed, can lead to benefits in four distinct areas of systems engineering: (1) interoperability, (2) standardization, (3) testing, and (4) data (...) exploitation. Reaping these benefits in a model-based systems engineering (MBSE) context requires utilizing an ontology’s vocabulary when modeling systems and entities within those systems. If the chosen ontology abides by the principles of ontological realism, a semantic standard capable of uniting distinct domains, using BFO as a hub, can be leveraged to promote greater interoperability among systems. As interoperability and standardization increase, so does the ability to collect data during the testing and implementation of systems. These data can then be reasoned over by computational reasoners using the logical axioms within the ontology. This, in turn, generates new data that would have been impossible or too inefficient to generate without the aid of computational reasoners. (shrink)

Although other quasi-Kantian theories have been adapted, Jürgen Habermas’s discourse theory has been largely ignored in discussions of environmental ethics. Indeed on some versions of what an environmental philosophy must entail, Habermas’s anthropocentric approach must be disqualified from the start. Yet, there are some environmentally friendly implications of his discourse theory. They may not give us everything we would wish, but in the contemporary political context we must treasure any moral theory that can draw on the still-extensive theoretical and political (...) resources of liberalism.

Heidegger’s characterization of Dasein as Being-in-the-world suggests a natural relation to environmental philosophy. Among environmentalists, however, closer inspection must raise alarm, both since Heidegger’s approach is in some senses inescapably anthropocentric and since Dasein discovers its environment through its usability, serviceability, and accessibility. Yet Heidegger does not simply adopt a traditionally modern, instrumental view. The conditions under which the environment appears imply neither that the environment consists only of tools, nor that what is true of the parts is also true (...) of the whole, nor that an orientation to use—where appropriate—precludes any other orientation. Heidegger’s anthropocentric commitments thus do not rule out the possibility of a non-instrumental perspective on the natural world. (shrink)

Since my article in C.Q. xli, pp. 86 ff., a further discussion of the problem has come to my notice. H. Jacobsohn, in an article entitled Σκνθικ in Zeitschr. f. vergleichende Sprachforschung, liv, pp. 254 ff., anticipates my point that the Greek ᾊξενƿς is borrowed not from Avestan but from some other Iranian language, probably Scythian. He also makes outan attractive case, based on the word παφδεισ¿ς, for considering the Iranian pronunciation at the period when the loan occurred to have (...) been αχšēna, with ē from original ai. It is unfortunate that he should have supported his case with the argument that a form αχšaina is too remote from Greek ξειν¿ς for the identification to have taken place: this insistence on complete homonymy in folk-etymology I have already criticized in discussing Moorhouse's article; and in any case it is by no means certain that ξεινႿς is the earliest form of the name in Greek.

The following modern editions are referred to: Sillig ; Jan ; Mayhoff ; Bailey , The Elder Pliny's Chapters on Chemical Subjects ; Loeb editions ; Budé editions . Abbreviations include: Urlichs1 = K. L. Urlichs, Chrestomathia Pliniana ; Urlichs2 = K. L. Urlichs, Vindiciae Plinianae ii.

By far the best edition is that of L. D. Reynolds . Other modern editions referred to are those of W. C. Summers ; R. M. Gummere ; F. Préchac et H. Noblot.

Before daybreak on 23 November 57 B.C., about 11 weeks after his return from exile, Cicero wrote to Atticus and recorded for him, in diary form, events at Rome between 3 November and the date of writing. Clodius and his gangs were still causing trouble on the streets, interfering with the rebuilding of Cicero's house on the Palatine, and even molesting Cicero himself. Clodius was a candidate for the curule aedileship; if he were elected, he would succeed in evading the (...) accusation for vis which had been brought against him by Milo; he therefore made full use of his gangs to intimidate Rome and thus accelerate the elections. He was supported in this manœuvre by the consul Q. Caecilius Metellus Nepos, who planned to hold the comitia by surprise; this plan, however, was being thwarted by the tribune Milo, who was ready to use his power of obnuntiatio to prevent the elections being held.

The most recent and by far the best edition of this work is that of H. M. Hine , to which I refer for full bibliographical information. Many passages of the text are most helpfully discussed in the same scholar's Studies in the Text of Seneca's Naturales Quaestiones . ut nubes infici possint, … sol ad hoc apte ponendus est; non enim idem facit undecumque effulsit, et ad hoc opus est radiorum idoneus ictus. Seneca is dealing with rainbows. Hine shares (...) Axelson's suspicion of ictus, but is unhappy both with Axelson's situs and with my tractus, ‘direction’ ; very tentatively he suggests angulus. Much more credible palaeographically and still yielding good sense and a good clausula would be i etus, a noun which is very common in this work of Seneca's. Hostius fuit Quadra obscenitatis in scaenam usque perductae. (shrink)

The pseudo-Ciceronian Epistula ad Octavianum enjoys the unmerited distinction of being preserved not only in most of the manuscripts which contain the Ad Atticum letters but also in some of those which contain the second half of the Ad Familiares letters; the former tradition is usually designated Ω, the latter I shall designate X. It was on the Ω tradition that the earliest printed texts were based. In the sixteenth century Cratander and Turnebus introduced a number of readings from the (...) X tradition; some of these were incorporated in the vulgate, but the printed editions from that of Lambinus to that of Purser still continued to be based mainly on Ω. In 1913, in an article in Eranos, xiii. 136–46, Sjögren set himself to prove that the value of Ω had been overrated in the establishment of the text, and that greater importance should be attached to X than to Ω; and in accordance with this view, in his 1914 Teubner text, Sjögren follows X, as against Ω, about twice as often3 as Purser does. This view of Sjögren's, I believe, will not stand examination, and to disprove it is the purpose of the present article. (shrink)

This is a concise introductory textbook for a one semester course in the history and philosophy of mathematics. It is written for mathematics majors, philosophy students, history of science students and secondary school mathematics teachers. The only prerequisite is a solid command of pre-calculus mathematics. It is shorter than the standard textbooks in that area and thus more accessible to students who have trouble coping with vast amounts of reading. Furthermore, there are many detailed explanations of the important mathematical procedures (...) actually used by famous mathematicians, giving more mathematically talented students a greater opportunity to learn the history and philosophy by way of problem solving. Several important philosophical topics are pursued throughout the text, giving the student an opportunity to come to a full and consistent knowledge of their development. These topics include infinity, the nature of motion, and Platonism. This book offers, in fewer pages, a deep penetration into the key mathematical and philosophical aspects of the history of mathematics. (shrink)

Odysseus' man, disguised as the captain of a merchant ship, is explaining to Neoptolemus how he chanced unexpectedly to meet Neoptolemus' sailors. Jebb's note, ‘the same land ; not, strictly, the same “spot” ’, and his rendering, ‘off the same coast’, somewhat contradict one another.

Since S000983880000149X_inline1 is a good Greek word, most scholars have assumed that it must be retained, and that the corruption is confined to the unintelligible letters which precede it. Constans deleted these letters as the remnant of a gloss, Sternkopf emended them to velut; neither solution is satisfactory, since S000983880000149X_inline2 by itself, without an indication of the recipient, is hardly intelligible.
