about both ---and

ignoring the actual 'meaning of the text which is confusing at best, first leave out the 'the' before 'advantage', and either will do, but the comparison is somewhat mute since in both cases the style is poor, and it is 'wordy'.

i suggest:
"Wise people will find advantage in adhering to adequate beliefs and by compromising undue ones, while fools often fall into trouble from untimely persistence or inappropriate compromise."

you are right, Bogowo, i am trying to make my writing more terse and incisive. thank you.
