The Nominalist Ontology of William of Ockham

 

Index of the Section: "The Problem of Universals from the Antiquity to Middle Ages"

 

INTRODUCTION

"Like most philosophers in the Aristotelian tradition, Ockham distinguishes between propositions and the terms out of which they are composed. Central to Ockham's analysis of the concept of a term is his distinction between categorematic and syncategorematic terms. We can get at this dichotomy if we distinguish between expressions that do and expressions that do not yield a meaningful proposition when substituted for x in 'This x -es' or 'This is (a/an) x'. The former (including predicate-expressions, proper names, demonstratives, and pronouns) Ockham calls categorematic terms; the latter (including articles, particles, interjections, quantifiers, and truth-functional connectives) he calls syncategorematic terms.

It is among categorematic terms that Ockham locates the distinction between singular and general, or employing Ockham's own terminology, the distinction between discrete and common terms. Very roughly, this is the distinction between categorematic terms that can and categorematic terms that cannot function as predicate in subject-predicate propositions, or that at least is the way a contemporary Ockhamist would express the dichotomy. Ockham himself construes the subject-predicate nexus more broadly to include identity-statements, existential propositions, and propositions incorporating either the universal or particular quantifier. Against this broad interpretation of subject-predicate discourse, Ockham tells us that while the discrete term is predicable of just one thing, the common term is predicable of many.

I have indicated that this distinction has traditionally been associated with the distinction between universals and particulars. For the medieval, the view that these two distinctions are related was legitimized by Aristotle's claim that the universal is that which is predicable of many. In a number of medieval philosophers this relation was explicated in terms of the notion of signification. The claim was that while discrete or singular terms signify particulars, common or general terms signify universals.

In medieval semantics, 'signify' was used as a transitive verb linking categorematic terms with their non-linguistic counterparts. Underlying this usage was the notion that categorematic terms are signs of objects, and the concept of a sign at work here was interpreted in psychological terms. A categorematic term is the sign of an object in the sense that the utterance of the expression has the effect of "bringing that object before the mind" of anyone familiar with the conventions governing the language in which the expression is embedded. The fact that signification involves a word-thing relationship suggests that the medieval notion of signification corresponds to the contemporary notion of reference; but in fact, the two concepts are quite different. The contemporary view tends to be that terms refer (or are used to refer) to objects only within the context of a proposition. The medievals, however, held that the signification of a term is a property which it exhibits quite independently of its role in any particular proposition; and they claimed that, at least in the case of univocal terms, the significatum of a categorematic expression is invariant over the various referential uses to which the term is put. Although it is explicitly relational, the medieval notion of signification is probably closer to the contemporary notion of meaning. In contemporary terms, the medievals were claiming that to know the meaning of a categorematic term is to know which object is its significatum."

    Texts translated into English with commentary by Martin M. Tweedale.
    "This work is meant to make accessible to students of philosophy and later medieval thought the key texts in one of the most crucial philosophical debates of that period. The concentration is on Scotus's positive doctrine since it is difficult and has not received the detailed attention it deserves. Ockham's polemic against Scotus raises a host of objections to the internal coherence of Scotus's reworking of the traditional line. Some of these are ones it seems to me Scotus could have countered quite easily; others would have required some revisions, but ones that are basically within the spirit of the doctrine. Some, however, are very difficult indeed, and I shall leave to the commentary and its introductory essay the exposition of my own view on whether Scotus's position can survive intact. There is also a positive side to Ockham's views about universals, and that is only partially covered in what follows. The texts that show how Ockham envisioned preserving all the essentials of Aristotelian science even after real universals have been excised, are presented and discussed, and the very real issue of whether Ockham's effort here could possibly succeed is broached but not definitely resolved one way or the other."

     

  5. Scotus vs. Ockham - A medieval dispute over Universals. Vol. II: Commentary. Lewiston: The Edwin Mellen Press 1999.
    "The commentary which composes the greater part of this volume attempts not only to explain the texts translated in the Iirst volume and to understand the positions adopted by the protagonists in this debate, but also to assess the cogency of the various arguments put forward. After all that work is done, however, there remains the task of drawing attention to the crucial issues that have emerged and arriving at some understanding of the debate as a whole and the relative merits of the positions put forward. It is this task that this introductory essay undertakes. Perhaps it would be better read after a thorough study of the commentary, but I am inclined to think that some awareness of the general issues and positions taken by Scotus and Ockham helps in making one's way through the individual texts and their often elaborate argumentation. In explaining these issues and positions I have made free use of philosophical ideas of our own day, at least to the extent that this is not grossly anachronistic."

    This exposition of Ockham's theory of (common, personal) supposition involves the logical form of the four descent/ascent conditions and the logical relations of these with the three main modes of supposition. Central theses: each condition is a one-way entailment, each mode is a truth-functional combination of conditions, two of the three modes are not even coextensive with the two-way entailments commonly taken as their definitions. Ockham's idea of "the singulars" of a general proposition is vague and problematic and the entailment used in the descent/ascent conditions probably cannot be taken to be logical consequence in any strict sense.

    "IV. Schlußbetrachtung. Ockham anerkennt ohne Einschränkung den transzendenten Bezirk, d. h. das Metaphysische oder Übersinnliche als Bezirk; in diesem Sinne ist er also gewiß kein Antimetaphysiker. Aber verwirft er denn die Metaphysik als Wissenschaft, oder höhlt er sie zumindest aus? Zuerst muß anerkannt werden, daß Ockham im Prinzip der Metaphysik das Weisungsrecht über die Seienden (d. h., für Ockham, die individuellen Seienden) keineswegs abspricht. Zugleich kann nicht geleugnet werden, daß bei ihm der Metaphysik eine auffallend bescheidene Stelle zukommt. Wie läßt sich das unter Berücksichtigung von Ockhams unzweifelbarer Ehrfurcht vor dem Übersinnlieben erklären?
    Der Schlüssel zur Lösung dieser Frage liegt nicht bloß in Ockhams Ontologie des individuellen Seins, sondern auch in seinen anthropologischen Auffassungen. Der Mensch ist nach ihm in seinen Denken und Sprechen nicht imstande, das Erhabene wesentlich zu durchforschen. Dessen soll sich der Mensch fort während eingedenk sein. Dies ist für Ockham in zwei deutliche Strategien übersetzbar:
    a) nicht jedem modus significandi oder loquendi entspricht ein modus essendi in der Wirklichkeit
    b) viele maßgebende Aussagen, sowohl sakrale wie profane, soll man nicht de virtute sermonis (dazu reicht unser Sprechen zuwenig aus), ondern der Ab sicht des Redners oder Schriftstellers entsprechend deuten." pp. 326-327 (Notes omitted).

    Reprinted as chapter XIII in: Through language to reality: studies in medieval semantics and metaphysics.

    "Conclusion. There is no single reason, I think, to ascribe to Ockham any feelings of hostility towards metaphysics on this account. God created 'true and real being', but He created it in shaping 'what is truly and really being', individual beings, that is. As created, it is radically changeable and contingent as well. Uncreated, unchangeable being is not to be created, not even as some mysterious constituent present in creatural being. Human beings are not entitled to sublimate their (indispensable) conceptual tools (e.g. universal terms) so that they represent unchangeable ontic standards. Whenever we are inclined to do so, Ockham's razor comes in, not however, to make us say that the metaphysical domain is void. Rather logic (and human thought in general) should make us recognize our own limitations, and refrain from speaking about the unspeakable when, and inasmuch as, our linguistic tools are bound to lead us astray. The same applies to Ockham's view of proofs of God's existence. He only admits the proof of God as first preserver of these actual things in this actual world and rejects all atemporal proofs. However, his faith is unshakeable and not involved in any philosophical thinking either. Likewise it is Ockham's ontology (doctrine of being) which is modest, the onta 'beings') are as abundant as they are. For that matter, Ockham let them really be (ontôs einai Plato would say). Well, in order to let them be, human thinking should be prudent in cautiously managing its homemade conceptual apparatus." pp. 38-39

    "Far from being a sceptic William of Ockham made every effort to corroborate the basis of philosophical and theological thought by purifying it of all sorts of untenable presuppositions. His main contribution to fourteenth century philosophical and theological development lies in systematically rethinking scholastic doctrines, and especially their assumptions, on the firm basis of his own favourite leading principles: the strictly individual nature of all that really is and the radical contingency of all creatural being.
    These two principles also play a major part in Ockham's way of dealing with the Aristotelian theory of demonstration. The present paper aims at investigating Ockham's doctrine of demonstrative proof, focusing on the way in which he felt forced to adapt or rephrase the special requirements Aristotle had laid down for propositions to enter into syllogistic proof, especially strict proof (the so-called 'demonstratio potissima'). Our main argument will concern Aristotle's rather peculiar 'kath holou' requirement and Ockham's appliance of the 'kath hauto' (Latin: `per se') notion which is also involved in framing correct premisses for demonstrative proofs. A few preliminary remarks will be made about the essentials of Aristotle's theory of demonstration." p. 232
    (...)
    "Conclusions.
    To sum up our findings: Ockham's adaptations and manipulations of Aristotle's requirements for genuine demonstrative propositions are as many demands imposed by his own metaphysical views. He comments on Aristotle, always starting from his own favourite views. Though Aristotle is the Master, Ockham is the one to say what the Master meant, or what he should have meant. On the other hand, his introducing the `per se strictissimo modo' rather seems to be a matter of technicality. Whereas in Posterior Analytics Aristotle deals with the scientific procedure of apodeixis in general, in which the apodeictic syllogism is merely a vehicle for correctly framing an apodeixis, the Medievals, and Ockham in particular, were apt to reduce Aristotle's theory of demonstrative proof to a theory of demonstrative syllogism. That is why the 'demonstratio potissima' (including its specific demands) so heavily influenced Ockham's theory of demonstration." p. 239

    "The present paper aims to clarify the attitude towards Aristotle adopted by one of the leading lights of fourteenth century philosophical and theological thought, William of Ockham, by investigating (a) how in some of the vital subjects of Aristotelian doctrine, the Venerable Inceptor understood and interpreted the Master, (b) how and why on specific occasions, he deliberately took the liberty to stray from Aristotle's teachings. It goes without saying that in such an undertaking, one has to confine oneself to certain doctrinal themes the choice of which might seem quite arbitrary. The present author has picked out the Aristotelian doctrine of demonstrative proof as interpreted by Ockham." p. 78

    "Connotation plays a central role in Ockham's analysis of the language of natural philosophy and mathematics. Some simple connotative terms belong to the deep structure of mental language. Ockham's program cannot guarantee the objectivity of things being quantified or located in space and time without his connotation-theory. Ockham's theory provides a partial explanation of why fourteenth- century philosophers shifted attention from discussion about the objects of mathematics to discussion of mathematics as a language. The shift explains in part the adoption of mathematical and metalinguistic approaches to philosophical and theological problems."

    "Many medieval grammar and logic texts contain treatments of relativa grammaticalia, expressions some of which we now call anaphoric pronouns. The first philosopher who paid attention to these treatments seems to have been Peter Geach. Apparently, Geach found their treatments both stimulating and frustrating.' In his main work on semantics, Reference and Generality (1), he presents some theses of Walter Burleigh's on this topic, a fourteenth century logician and opponent of William Ockham, at considerable length. Elsewhere, however, he remarks that while 'the logic of pronouns with antecedents was extensively studied by medieval logicians in their chapters de suppositione relativorum; [...t]his medieval treatment of pronouns was inconclusive" (2) and that '[...] the medievals who discussed relativa - pronouns with antecedents - were groping in the dark despite all their ingenuity'. (3) What Geach deplored was the apparent tendency of 'the medievals' to treat anaphoric pronouns, relativa grammaticalia substantiae identitatis in terms of co-reference, of 'supponere pro eodem'. As is well known, Geach himself favors a rather different approach, according to which it is nonsense to talk about the reference of such pronouns at all, for they act like bound variables. His view on pronouns has now a considerable number of adherents and a few critics - most notably Gareth Evans. (4)
    I am not concerned here with the question whether Geach's own theory of pronouns is correct, but whether his verdict about medieval theories of relativa is justified. His verdict is of unrestricted generality: it is not some medieval treatment of pronouns that is inconclusive, but "the" medieval treatment. This makes his claims an easy target for counterattack: Just find some medieval logician, whose theory does not fit Geach's claims. I have done this elsewhere. (4) Here I want to consider two logicians Geach has actually dealt with himself: Burleigh and Ockham.

    "This volume gives an introduction to William Ockham's theory of signs, his ontology, his epistemology, and the interrelations between these fields. Some recent results of analytic philosophy turn out to be useful instruments for the interpretation of Ockham's thought.
    Part one contains a presentation of the basic concepts of Ockham's semantics. It is followed by an investigation of his ontology, including a comparison with modern ontology. Part three deals with the common and different elements in the conceptions of supposition and of quantification. Part four shows some similarities of Ockham's views on the truth of sentences with those of Davidson. The final part presents Ockham's epistemology within the discussion of his contemporaries and confronts it with actual issues raised by Quine and Putnam."

    "The distinctions between singular and general terms, on the one hand, and abstract and concrete terms, on the other, play crucial roles in discussions of ontological issues. Although these dichotomies can be expressed in purely grammatical terms, they have traditionally been thought to point to two over-arching distinctions among things. Philosophers have frequently claimed that the singular-general term distinction is rooted in a distinction between objects that are particulars and objects that are universals; whereas, the distinction between concrete and abstract terms forces us to confront the distinction between substances (minimally interpreted to include material bodies and persons) and the various characteristics they possess or exhibit.
    But because they appear to carry these far-reaching metaphysical implications, these grammatical dichotomies receive detailed treatment at the hands of the nominalist. If his theory is to be at all plausible, the nominalist must have the resources for providing a metaphysically neutral account of the singular-general and concrete-abstract dichotomies. In this essay I want to examine William of Ockham's ontology by focusing on his treatment of these distinctions. My aim here is twofold. By examining Ockham's analysis I hope to provide an introduction to the central themes of Part I of the Summa Logicae and to clarify the concept of a nominalistic ontology in general." p. 1

    "The author analyses philologically and philosophically the two different expressions 'nomen' and 'terminus' used by Ockham in the chapters given up to the supposition theory in his "Summa logicae". By that we can say that Ockham's logic of terms is interested primarily in the words, and in the concepts just with reference with these last ones, without qualifying Ockham's logic as 'nominalist': in fact 'nomen' receives his own capacity of meaning by the concept as natural linguistic sign."

    "Within the Ockhamist semantics, the predicate 'true' is explained by another more basic semantical relation, the relation of supposition.
    The author shows how this relationship between two semantical predicates figures in the analysis of the truth-conditions of propositions about the past, and demonstrates that it is a model that can be extended to propositions about both the future and the possible. The author indicates how the semantics of alethic modalities is in continuity with the semantics of propositions about the past and about the future. If we consider another aspect of Ockham's modal theory, viz., the fact that modalities are defined as any term that can be predicated of a whole proposition, the importance of this point becomes clear. In conclusion, the author points out the different levels of analysis of alethic modalities within an Ockhamist framework."

    "The importance of the connotation theory in Ockham's semantics and metaphysics can hardly be overstated--it is the main mechanism that brings forth Ockham's famous ontological elimination. Yet none of the extant interpretations can satisfactorily accommodate three widely accepted theses: (1) there is no synonym in mental language; (2) a connotative term has a semantically equivalent nominal definition; and (3) there are simple connotative terms in Ockham's mental language. In this paper I offer an interpretation that I argue can accommodate all."
