That’s bs. Even just the preface to Phenomenology of Spirit is chock full of ideas that folks would be better off if they contemplated. Hegel can be considered a visual thinker (or visionary) whose ideas don’t need “measurement”. If folks understand his thoughts on the master-slave dialectic, for example, they would have an idea as to why we have such incompetent leaders like trump. His thought suffers from the same problem of any thinker who tried to be systematic, but it is still worth being inspired by.
