The Answer to the Agony location (Origins of Stern)

Clue

"Greetings! I am a scientist who gave up his body a long time ago in order to surpass the limits of humanity. I have lived for several hundred years. You may doubt that a floating brain could be of any help, but my understanding of the world exceeds that of any other living person. Don't you want to go beyond the limits of Human knowledge? If you do, then bring me the Knowledge Logs spread across Stern. They will clear all of my lingering doubts!"

Story

After I have collected all the fragments of knowledge, I went to visit the scientist's brain. Is he supposed to reach a higher level of understanding once he gains all this knowledge? "What should I do? My kid mistook the ketchup bottle... and the great-great-grandfather unfortunately... Well, actually... He was not functioning properly anymore, so maybe it's time."
