Wel may men knowe, but it be a fool,
That every partye dyryveth from his hool.
For nature hath nat take his bygynnyng
Of no partye ne cantel of a thing,
But of a thing that parfyt is and stable,
Descendyng so, til it be corumpable.
(Knightes Tale, vol. ii. p. 92.)
For al þing þat is cleped inperfit . is proued inperfit by þe amenusynge of perfeccioun . or of þing þat is perfit . and her-of comeþ it . þat in euery þing general . yif þat . þat men seen any þing þat is inperfit . certys in þilke general þer mot ben somme þing þat is perfit. For yif so be þat perfeccioun is don awey . men may nat þinke nor seye fro whennes þilke þing is þat is cleped inperfit . For þe nature of þinges ne token nat her bygynnyng of þinges amenused and inperfit . but it procediþ of þingus þat ben al hool . and absolut . and descendeþ so doune in-to outerest þinges and in-to þingus empty and wiþ-oute fruyt . but as I haue shewed a litel her byforne . þat yif þer be a blisfulnesse þat be frele and vein and inperfit . þer may no man doute . þat þer nys som blisfulnesse þat is sad stedfast and perfit.’
(bk. iii. pr. 10, [p. 89].)
Omne enim quod imperfectum esse dicitur, id deminutione perfecti imperfectum esse perhibetur. Quo fit ut si in quolibet genere imperfectum quid esse videatur, in eo perfectum quoque aliquod esse necesse sit. Etenim perfectione sublata, unde illud, quod imperfectum perhibetur, extiterit, ne fingi quidem potest. Neque enim ab diminutis inconsummatisque natura rerum cepit exordium, sed ab integris absolutisque procedens in hæc extrema atque effœta dilabitur. Quod si, uti paulo ante monstravimus, est quædam boni fragilis imperfecta felicitas, esse aliquam solidam perfectamque non potest dubitari.
