The Nature of Good and Not Good

Six a four and six a five get into this external versus internal thing It's a weird section because I feel like menshes his position against this guy gao zi is just that Your distinction between internal and external doesn't make any sense So let's go ahead and lay it out and maybe we'll have our own version of what this means. In six a two human nature does not distinguish between good and not good Anymore than water distinguishes between east and west According to the opponent sorry pwng so I gave two different theories for this, but there's a third which is just that there's no internal propensity towards either Right, but mensius is reply, right?
