All negroes are black. (i.e. The pot is calling the kettle black)
German: Ein Neger hat dem andern nichts vorzuwerfen. [op.cit.]
Comment:
Here de could be copula as well as aspect marker. Note that elsewhere a similar sentence occurs without de (see Example 185). The presence of de may have to do with emphasis (cf. the underlining of ein in Schumann's translation).
