Carelessness in the singing of the services was not, however, the most serious result of reaction against routine. If the men and women of sensibility failed to keep intelligence active in the pursuit of spiritual or temporal duties, if they cared no longer to use brain and spirit as they performed the daily round, accidia[922], that dread disease, half ennui and half melancholia, which, though common to all men, was recognised as the peculiar menace of the cloister, lay ever in wait for them. Against this sin of intellectual and spiritual sloth all the great churchmen of the middle ages inveigh, recognising in it the greatest menace of religious life, from which all other sins may follow[923]. If accidia once laid hold upon a monk he was lost; ceasing to perform with active mind his religious duties, he would find them a meaningless, endless routine, filling him with irritation, with boredom and with a melancholy against which he might struggle in vain. The fourth century cenobite Cassian has left a detailed description of the effects of accidia in the cloister, declaring that it was specially disturbing to a monk about the sixth hour “like some fever which seizes him at stated times,” so that many declared that this was “the sickness that destroyeth in the noon day,” spoken of in the ninetieth psalm[924]. Many centuries later Dante crystallised it in four unsurpassable lines. As he passed through the fifth circle of hell he saw a black and filthy marsh, in which struggled the souls of those who had been overcome by anger; but deeper than the angry were submerged other souls, whose sobs rose in bubbles through the muddy water and who could only gurgle their confession in their throats. These were the souls of men who had fallen victims to the sin of accidia in their lives

Fitti nel limo dicon: Tristi fummo
Nel’ aer dolce che dal sol s’ allegra,
Portando dentro accidioso fummo:
Or ci attristiam nella belletta negra.

Fixed in the slime, they say, “Sullen were we in the sweet air, that is gladdened by the sun, carrying lazy smoke in our hearts; now lie we sullen here in the black mire”[925].

But the working of the poison is most brilliantly described by Chaucer, in his Persones Tale:

“After the sinnes of Envie and of Ire, now wol I speken of the sinne of Accidie. For Envye blindeth the herte of a man, and Ire troubleth a man; and Accidie maketh him hevy, thoghtful and wrawe. Envye and Ire maken bitternesse in herte; which bitternesse is moder of Accidie and binimeth him the love of alle goodnesse. Thanne is Accidie the anguissh of a trouble herte.... He dooth alle thing with anoy and with wrawnesse, slaknesse and excusacioun, and with ydelnesse and unlust.... Now comth Slouthe, that wol nat sufre noon hardnesse ne no penaunce.... Thanne comth drede to biginne to werke any gode werkes; for certes he that is enclyned to sinne, him thinketh it is so greet an empryse for to undertake to doon werkes of goodnesse.... Now comth wanhope, that is despeir of the mercy of God, that comth somtyme of to muche outrageous sorwe, and somtyme of to muche drede; imagininge that he hath doon so much sinne, that it wol nat availlen him, though he wolde repenten him and forsake sinne: thurgh which despeir or drede he abaundoneth al his herte to every maner sinne, as seith seint Augustin. Which dampnable sinne, if that it continue unto his ende, it is cleped sinning in the holy gost.... Soothly he that despeireth him is lyk the coward champioun recreant, that seith creant withoute nede. Allas! allas! nedeles is he recreant and nedeles despeired. Certes the mercy of God is euere redy to every penitent and is aboven alle hise werkes.... Thanne cometh sompnolence, that is sluggy slombringe, which maketh a man be hevy and dul in body and in soule; and this sinne comth of Slouthe.”

He proceeds to describe further symptoms,

“Necligence or recchelnesse ... ydelnesse ... the sinne that man clepen Tarditas” and “Lachesse,”

and concludes thus,

“Thanne comth a manere coldnesse, that freseth al the herte of man. Thanne comth undevocioun, thurgh which a man is so blent, as seith seint Bernard, and hath swiche langour in soule, that he may neither rede ne singe in holy chirche, ne here ne thinke of no devocioun, ne travaille with his handes in no good werk, that it nis him unsavory and al apalled. Thanne wexeth he slow and slombry, and sone wol be wrooth, and sone is enclyned to hate and to envye. Thanne comth the sinne of worldly sorwe, swich as is cleped tristicia, that sleeth man, as seint Paul seith. For certes swich sorwe werketh to the deeth of the soule and of the body also; for therof comth, that a man is anoyed of his owene lyf. Wherfore swich sorwe shorteth ful ofte the lyf of a man, er that his tyme be come by wey of kinde”[926].

This masterly diagnosis of the sin of spiritual sloth and its branches is illustrated by several stories which bear unmistakably the impress of a dreadful truth. Johann Busch’s account of his early temptations and doubts has often been quoted. A strong character, he overcame the temptation and emerged stronger[927]. But Caesarius of Heisterbach has two anecdotes of weaker brethren which show how exactly Chaucer described the anguish of a troubled heart. The first is of particular interest to us because it concerns a woman:
