In the sentence "Auch in dieser Rücksicht zeigt sich die Stellung zu vergangenen Systemen gewissermaßen günstiger", is "Stellung" here referring to "Einstellung" (towards the systems) or rather to the "Position" (of the systems)?
"Einstellung" is a point of view or way of thinking, so it usually applies to a person. "Position" can refer to the place of an object, but also to the place of a person in a hierarchy. Unfortunately, the fragment doesn't show whether it refers to a person or an object.
Also "Rücksicht" in this context, especially with "vergangene" (past), almost certainly means "looking back (into the past)".
