Julia does seem to be the most sensible character. I also wonder if she read the Prologue & Epilogue because her character got the least stage time of the female leads or perhaps because the actress was better at such long speeches.

Women are paid homage in the epilogue:

In female breasts did sense and merit rule,
The lover's mind would ask no other school;
Shamed into sense - the the scholars of our eyes,
Our beaux from gallantry would soon be wise;
Would gladly light, their homage to improve,
The lamp of knowledge at the torch of love!
