The Distinction between Res Significata and Modus Significandi in Aquinas’s Theological Epistemology

THE DISTINCTION BETWEEN RES SIGNIFICATA AND MODUS SIGNIFICANDI IN AQIDNAS'S THEOLOGICAL EPISTEMOLOGY GREGORY RoccA, O.P. Dominican School of Philosophy and Theology Berkeley, California ST. THOMAS AQUINAS often refers to the distinction between res significata and modus significandi. He asserls that, whie the :absolute and analogical predicates of positive theology may be pveditcated of God with regard to their RS,1 they mrust ,be denied of God with regard to their MS.2 The distinotion, then, is an imporlant element in his 1 For brevity's sake I will refer to res significata, by RS and to modus significand.i by MS; I will also speak of the res/modus distinction. The following abbreviations for Aquinas's works will be used: BDH=Flropositio in librum Boethii De hebdomadibus (Marietti ed., 1954); DA=the disputed question De anima (ed. J. H. Robb [Toronto: PIMS, 1968]) ; DDN=Flropositi super librum Dionysii De divinis nominibus (Marietti ed., 1950); DP=De potentia (Marietti ed., 1949); DSS=De substantiis separatis (Leonine Commission , vol. 40, 1969); DV=De veritate (Leonine Co=ission, vol. 22, 197276 ); Herm.=Sententia libri Peri hermeneias (Marietti ed., 1955); John= Leotura super Johannem (Marietti ed., 1952); Meta.=Sententia libri Metaphysioorum (Marietti ed., 1950); Phys.=Sententia libri Physioorum (Marietti ed., 1965) ; Quod. = Quaestiones quodlibetales (Marietti ed., 1956) ; BOG= Summa contra gentiles (Marietti ed., vols. 2-3, 1961) ; SDO=Eropositio super librum De causis (Marietti ed., 1955) ; SS=Scriptum super libros Sententiarum (Paris: Lethielleuro, 1929, 1933, 1947); ST=Summa theologiae (Alba/ Rome: Editiones Paulinae, 1962). The English translations are my own. For Thomas's positive theology of the divine names, see Gregory Rocca, "Analogy as Judgment and Faith in God's Incomprehensibility: A Study in the Theological Epistemology of Thomas Aquinas" (Ann Arbor: University Microfilms International, 1989) 540-615. 2 A characteristic text: "In every name predicated by us [of God], imperfection is found with respect to the name's mode of signifying [MS], 173 174 GREGORY ROCCA, O.P. theological epistemology and onomatofogy.3 For some, however, the distinction wou1d ultimately lead us back to the univocist camp of Duns Scotus,4 for they see it as hiding within itself 1 a latent core of univocity. One writes that the predication involved in 1anafogy of attribution is both univocal and equivocail: " It is univocal, insofar as it ai1ways denotes the siame proprietas rei; it is equivoca,J since, through a differrent modus significandi, it •connotes ' a different existentiail mode of the denoted proprieta.'J." 5 Another writes, in simil.ar fashion, that "the :same property is signifi·ed, hut the way in which the property inheres in the subject is different." a Another contends tha;t the idis:tinJCtion between RS and MS is a" bogus distinction between what words realily mean and what they mean to us." 7 If the res/niodus distinction is an imwhich does not belong to God, though the thing signified [RS'] is suitable to God in some eminent manner " (SOG l.30.277) ; the same sentiment is found in many other texts such as SS L35.LL ad2 and ST l.13.3. Thomas often explains the saying of Pseudo-Dionysius, that negations about God are true while affirmations are vague, by claiming that affirmations are true as regards their RS but not as regards their MS (SS l.22.l.2. adl; l.4.2.l. ad2; SOG l.30.277; DP 7.5 ad2; ST l.13.12. adl; SDO 6.161). a Hampus Lyttkens, however, thinks the distinction plays no essential role in Thomas's theory of the divine names (" Die Bedeutung der Gottesprltdikate bei Thomas von Aquin," N eue Zeitschrift fur systematisahe Theologie und Religionsphilosophie 6 [1964] 277-80). Klaus Muller claims the application of the res/modus distinction to the divine names " says really nothing at all" (Thomas van Aquins Theorie und Praxis der Analogie. Der Streit um das rechte Vorurteil und die Ana,lyse einer aufsohlussreichen Diskrepanz in der "Summa theologiae ", Regensburger Studien zur Theologie 29 [Frankfurt am Main/Bern/NY: Peter Lang, 1983] 100). 4 See Richard Swinburne, The Coherence of Theism (Oxford: Clarendon, HJ77) 78-80. s Jan Pinborg, Logik und Semantik im Mittelalter: liJin uberblick, Afterword by...
