If you read Hegel (or read someone interpreting him, I don't recommend reading Hegel unless you're a masochist), you'll find a key part of his approach was the limitations of observation. And Hegel wasn't even first to the gate on that one - philosophers have been questioning the value of observation relative to a comprehensive understanding of reality since the ancient Greeks (and the ancient Chinese, if you bring Taoism into it). There's a lot more to it than "meaningless unfalsifiable piffle".
