One could say 'the wisest sages know to value style and substance'

Or even: 'the wisest sages know that incorrect results can be based on some sound thinking and some muddled thinking, and correct results can be derived by tortuous thinking'

Or maybe: 'the wisest sages know that some things are neither objectively true nor objectively false, and can appreciate good arguments for positions they disagree with'
