Remember that everything is just opinion and belief. This truth was clear to Monimus the Cynic. And it's just as clear how useful this insight can be, if you accept what is true and serious about it along with what feels good and pleasant.
Remember that all is but opinion and conceit, for those things are plain and apparent, which were spoken unto Monimus the Cynic; and as plain and apparent is the use that may be made of those things, if that which is true and serious in them, be received as well as that which is sweet and pleasing.
