2.024 Substance is what persists [besteht] independently of what is the case.

Ogden has ‘exists,’ Pears & McGuinness have ‘subsists.’ Ogden’s version seems to make the sentence paradoxical-sounding. Perhaps ‘endures’ would be best.

What is there independently of what is the case? Perhaps substance is possibility? Or should we say possibility and necessity? Perhaps we should say it is logic. Better yet, perhaps we should stick with 2.024 as it stands, and treat it as a definition of substance.
