Thanks. I don't think external reality is subjective, but our understanding of it is always partly subjective, according to my pragmatic view of knowledge (link below). And even our concept of objectivity is social and practical. We objectify things as a prelude to controlling or enslaving them. We conquer by dividing things up.
