a later quote of Pechstein; as quoted in Brücke und Berlin: 100 Jahre Expressionismus, ed. Anita Beloubek-Hammer; Nicolaische Verlagsbuchhandlung, Berlin 2005, p. 266 (transl. Claire Albiez)
about the cause of the break-up of Die Brücke group in 1913: the harsh city-life of Berlin. Pechstein himself already was removed from the Brücke group in 1912 (one year before the definite break) because he went against the self-imposed rule of die Brücke to only exhibit together - when he decided to show also his art at the 'Berliner Secession'.

Context: Speciesism is an attitude of prejudice towards beings because they're not members of our species, so just as racism means that you're prejudiced against beings who are not members of your race and sexism means you're prejudiced against people of the other sex. So we humans tend to be speciesist in we think that any being that is a member of the species homo sapien just automatically has a higher moral status and is more important than any being that is a member of any other species, irrespective of the actual characteristics of those beings.
