⁴³ The distinction between tristitia utilis and sinful tristitia (by Guibert evidently called acedia), deriving from 2 Cor. 7.10, was a commonplace in medieval discussions of the vices, starting with Cassian, Inst. 9.10–11. Google Scholar

⁴⁴ Cassian, , Inst. 9.2–3, quoting Prov. 25.20, ‘Sicut tinea vestimentum….’ Guibert not only knew Cassian but considered him and St. Gregory the chief authorities on the inner life, ‘quorum lectio utilitatis immensae studiosis lectoribus fructum praestat’ (PL 156.27C). As to the capital vices, Guibert once refers to ‘octonus vitiorum capitalium numerus’ (422C). It is not clear which scheme he had in mind, but I suspect it was C with tristitia replaced by acedia.

⁴⁸ Epist. 78.4 (PL 182.193C). The greater emphasis on identifying acedia with taedium in St. Bernard and following authors of the twelfth century (in contrast to earlier authors in our survey) may have been influenced by the Glossa ordinaria (early twelfth century), which, in commenting on ‘Dormitavit anima mea prae taedio’ (Ps. 118.28), explains: ‘Dormitatio est quae dicitur accidia’ (ed. Antwerp 1617). The gloss comes from Cassiodorus (PL 70.846) and ultimately relies on Cassian, Inst. 10.4. Dormitatio is glossed as acedia also by Gerhoh of Reichersberg (PL 194.754) and Peter Lombard (PL 191.1058f.).Google Scholar

⁴⁹ Frigus is connected with Ps. 147:17: ‘A facie frigoris ejus quis sustinebit ?’ Before that, Bernard had mentioned aquilo, the cold north wind, which in biblical exegesis was traditionally connected with torpor mentis (cf.

⁶⁷ Ibid. (PL 32.1456). The basis for the idea that acedia can be overcome by a frequent change of occupation seems to be an exemplum relating St. Anthony's vision of an angel who alternates prayer with work: Apophthegmata; Antonius 1 (PG 65.76); Vitae Patrum V.vii,1 (PL 73.893, without ‘acedia’), whence it passed into later medieval literature as a standard exemplum against the vice.

⁹¹ The sizeable body of relevant (and much irrelevant) literature I have scanned yielded approximately 145 passages with acedia or acediosus — a rather meagre yield for five centuries. Of these, (a) 62 contain the terms within a scheme of vitia principalia; (b) 58 in isolation; and (c) some 25 in a series of vices usually including some or all of the chief ones. Many items of group (c) should therefore be counted with group (a); that is, in them acedia probably meant the chief vice and was suggested to the author by association with the vitia principalia. These figures should be taken cum grano salis because all three groups contain some instances whose classification is arguable. Google Scholar

⁹² See supra, p. 83. Google Scholar

⁹³ One might raise the question whether, in the twelfth century, the distribution of acedia depended on the intended audience. It seems as though in isolation the word occurs only in treatises on the spiritual life (except for dictionaries and glossaries), addressed to monastic audiences. At least one case substantiates this impression, the works by Richard of St. Victor. His commentary on Canticles deals with the spiritual life; it contains three passages with acedia in isolation (nos. 60–63). On the other hand, at least one of his sermons (23) is addressed to priests and tells them what to teach their people (PL 177.946); here acedia appears in the scheme of capital vices.Google Scholar

⁹⁴ In addition, Benedictine monasticism from the eighth to the tenth century seems to have stressed the contemplative life less than Cassian and Benedict had envisioned; see Rousselle, A.-Estève, ‘S.
