I got bits and pieces of what Dr. Daniel Robinson said in the video presentation below, and I'll try to explain them briefly in my own understanding. :)
"Intellectual history presents us with a set of ideas that building on precedents, on past mistakes, past understandings, lead us, maybe, toward the light in progress."
This can be simply put as "We learn from our mistakes". Yes, we sure do. For example, if you tripped on a certain part of a street, you would be cautious enough next time to watch out for that part of the street. You learned to be cautious, to observe. And in some cases, mistakes and past understandings serve as motivations, for us to do better next time around which therefore leads us toward the light in progress.
"The developments in Philosophy are chiefly in the form of greater clarity, an ever more refined sense of just what makes the problem, problematic. If ignorance is not thereby overcome, at least it's exposed."
I totally agree that philosophy makes everything complicated. It's what makes the problem, problematic. But Philosophy makes people understand the problem, not just solve it. As what Seneca said, "What use is knowledge if there is no understanding?"
