Character

Though they had now been acquainted a month, she could not be satisfied
that she really knew his character. That he was a sensible man,
an agreeable man, that he talked well, professed good opinions,
seemed to judge properly and as a man of principle, this was all
clear enough. He certainly knew what was right, nor could she fix
on any one article of moral duty evidently transgressed; but yet she would
have been afraid to answer for his conduct. She distrusted the past,
if not the present. The names which occasionally dropt
of former associates, the allusions to former practices and pursuits,
suggested suspicions not favourable of what he had been.
She saw that there had been bad habits; that Sunday travelling
had been a common thing; that there had been a period of his life
(and probably not a short one) when he had been, at least,
careless in all serious matters; and, though he might now think
very differently, who could answer for the true sentiments of a clever,
cautious man, grown old enough to appreciate a fair character?
How could it ever be ascertained that his mind was truly cleansed?
