Here 'it' seems to mean 'to live an upright life'; rather a harsh construction. It is not likely that the poet used 'mean' in the sense of mener Fr., yet it seems to be used so sometimes in Piers Ploughman.

Sc. 1.
"Cannot contain their urine; for Affection,
Masters of passion, sways it to the mood
Of what it likes or loathes."
The original editions all read "Cannot contain their urine for affection;" but that this cannot be right is proved by the context. The only question then is, should we read Master with Thirlby, or Mistress with the same and Capell. Nothing (see Introd. p.

In the last line I read she for 'it,' evidently caused by that in the preceding line. For the meaning of 'affection,' see [Index] s. v.
"Why he a woollen bag-pipe."
