    "However that may be, Aristotelian syllogistic concerned itself exclusively with monadic predicates. Hence it could not begin to investigate multiple quantification. And that is why it never got very far. None the less, the underlying grammar of Aristotle's logic did not in itself..

    "Philosophy meant Greek. Rome had nothing to offer except a stern traditional moralism exemplified by Cato, which found the rigid Semitic ethic of the Stoics congenial, and a reaction away from this, which expressed itself in a loose Epicureanism, such as Epicurus himself and his sincere exponents would have utterly disowned. 'And so it is not Epicurus who has driven them to debauchery. They have already given themselves over to immorality, and now try to hide their debauchery in the lap of philos…Read more

    "Husserl's work include lengthy treatment of universals, categories, meanings, numbers, manifolds, etc. from an ontological perspective. Here, however, we shall concentrate almost exclusively on the Logical Investigations, which contain in a clear form the ontological ideas which provided the terminological and theoretical basis both for much of the detailed phenomenological description and for many of the metaphysical theses presented in Husserl's later works

    "Any linguistic study of the Greek verb be is essentially conditioned, and perhaps ultimately motivated, by the philosophic career of this word. We know what an extraordinary career it has been. It seems fair to say, with Benveniste, that the systematic development of a concept of Being in Greek philosophy from Parmenides to Aristotle, and then in a more mechanical way from the Stoics to Plotinus, relies upon the pre-existing disposition of the language to make a very general and diversified use…Read more

    "General Survey. The succession of thinkers and schools. The history of ancient philosophy covers about eleven centuries, from Thales who lived during the sixth century B.C. to Boethius and Simplicius who flourished at the beginning of the sixth A.D. From the point of view of the history of formal logic this long epoch may be divided into three periods. (1) The pre-Aristotelian period, from the beginnings to the time at which Aristotle..

    "On the June 16th, 1996, Richard Sylvan died of a sudden and unexpected heart attack. His death, at the relatively young age of 60, robbed Australasia of one of its greatest philosophers, arguably the most original that it has ever produced. Richard was born Francis Richard Routley at Levin, New Zealand, on 13 December, 1935. He changed his name to Sylvan -- much to the confusion of a number of people -- when he remarried in 1983. After studying at the Victoria University of Wellington, he took …Read more

    "At the end of the fourteenth century there were roughly three categories of work available to those studying logic. The first category is that of commentaries on Aristotle's 'Organon'. The most comprehensive of these focussed either on the books of the Logica Vetus, which included Porphyry's Isagoge along with the Categories and De Interpretatione; or on the books of the Logica Nova, the remaining works of the 'Organon' which had become known to the West only during the twelfth century. In addit…Read more

    "In this essay, I wish to question the view that the distinction between medieval and early modern philosophy is primarily one of method. I shall argue that what has come to be known as the modern method in fact owes much to the natural philosophy of John Buridan (ca. 1295-1361), a secular arts master who taught at the University of Paris some three centuries before Descartes. Surrounded by conflicts over institutional governance and curricular disputes, Buridan emerged as a forceful voice for th…Read more

    "The difficulty of piercing the screen, sometimes very opaque, which is the Aristotelianism of so many centuries, based substantially on the thinking of a thousand and one more or less faithful "disciples," is doubled by a difficulty probably unique in its kind: the impossibility of always being able to determine exactly the sort of things the writings of the authentic Aristotelian Corpus are. For we suspect that scholars often have to deal with texts whose definitive form owes something to the …Read more

    especially Aristotle, and contented that philosophy proceeds in cycles of advance and decline. He is best known for reintroducing the scholastic concept of intentionality into philosophy and proclaiming it as the characteristic mark of the mental. His teachings, especially those on what he called descriptive psychology, influenced the phenomenological movement in the twentieth century, but because of his concern for precise statement and his sensitivity to the dangers of the undisciplined use of …Read more

Other philosophers belonging to the Peripatetic school were: Aristoxenus, Dikaiarchos, Phanias, Straton, Duris, Chamaeleon, Lycon, Hieronymus, Ariston, Critolaus, Phormio, Sotion, Hermippus, Satyrus and others. Straton even succeeded Theophrastus as director of the Lyceum but his name and those of the other Peripatetics of Aristotle's old school should not be considered in a history of logic as they were mainly concerned with history and …Read more

    "With Abelard, the term 'copula' enters into western thought. In fact, although widely attested, the use of the term 'copula' in reference to Aristotle's work is totally anachronistic. (1) What led to this term? In his Dialectica, Abelard was mainly concerned with the way syllogisms can be construed. The interest of the copula was in fact derivative from this main concern. As Kneale and Kneale (The development of logic, 1962: 206) put it, 'it is clear that for his [Aristotle's] theory of syllogi…Read more

    "Heidegger's way of understanding the originary phenomenon of truth is to "make clear the mode of being of the cognition itself." His starting point is a proposition that is not based on intuition. Someone says with his or her back to the wall: this picture hangs askew. The proposition embodies the claim to have discovered the picture (as a being) in the "how" (the mode) of its being. The proposition displays this "how" of being in language. In the attempt to verify the proposition by sensuous e…Read more

    "Abelard composed four works on logic: (1) Introductiones Parvulorum, which consists of short glosses on Porphyry Eisagoge and Aristotle Categories and De Interpretatione; (2) Logica Ingredientibus (so called because ingredientibus is the first word of its text), which consists of longer glosses on the texts covered by the previous work together with Boethius' De Differentiis Topicis and was probably written while Abelard was teaching in Paris before 1120; (3) Logica Nostrorum Petitioni (so call…Read more

    Now we should have to answer the question: when were the questions on Perihermeneias written? Little is known about the chronology of Buridan's works. Even a relative date is difficult to establish. However, some remarks can be made. First, there is the fact that the questions on Perihermeneias are quoted several times in Tractatus I of the Summule (4), in a way that makes it highly probable that the Summule were written after the Questiones on Perihermeneias (5). Now, according to professor Pinbo…Read more

He must be placed historically in fairly close proximity to Leibniz, with whom he shares important thoughts and fundamental conceptions, and to whom he is also p…Read more

    "The Sophist seems to be concerned with two things: being and nonbeing, on the one hand, and true and false speech, on the other. If speech is either true or false speech, it seems not even plausible for being to be either being or nonbeing, since we would then be compelled to say that nonbeing is as much being as false speech is speech. If nonbeing, however, is being, then nonbeing cannot be nonbeing, for otherwise the falseness of false speech would not consist in its saying 'nonbeing.' And, i…Read more

    "Ingarden held that philosophy divides into ontology and metaphysics. Ontology is an autonomous discipline in which we discover and establish the necessary connections between pure ideal qualities by intuitive analysis of the contents of ideas. This is an indispensable preparation for metaphysics, which aims to elucidate the necessary truths of factual existence. Each section of philosophy - theory of knowledge, philosophy of man, philosophy of nature and so on - has ontological and metaphysical…Read more

    "With the philosophy of Nicolai Hartmann we once again enter a world of sober, objective and impartial inquiry, which presses beyond man's self and seeks to grasp the universe of being so far as it is revealed to our limited capacity to know. The basic mood of Existence philosophy, as might be expected, is altogether missing from this universal way of viewing matters. (...). The true concern of his philosophy is to discover the structural laws of the real world, of the world of being, not of som…Read more

    "One of Frege's main semantic principles, is however, missing in Dummett's book, [Frege: philosophy of language] and it is has been ignored by most Frege scholars. That principle is the thesis concerning the ambiguity of the word 'is'.

However, the great majority of Frege scholars have neglected the ambiguity doctrine…Read more

    "Nowadays, a need for formal tools is strongly felt in the treatment of two special areas of ontological inquiry. One area is concerned with intentional objects, an area which seems to contain difficulties on the level of things, but also on the level of states of affairs, facts and other "propositional" entities. An intentional relation holds between either persons (more generally experiencing subjects) or acts of consciousness on the one hand, and the intentional objects on the other. The latter …Read more

    "The central theme of the De interpretatione is the nature of contradiction between assertions. This is a crucially important theme for dialectic, whose regular tasks include that of establishing the contradictory of a proposed thesis, and that of replying to a dilemmatic question by choosing between the affirmation and the negation of a given thesis.(4) The inquiry into language as such, which occupies the first four chapters, is subordinated to this goal. One apparent obstacle to such a view of t…Read more
