I like to think what Michael Stevens(VSauce) said in his video[1] as a continuation of Asimov's letter. "Susan Haack compares knowledge to a crossword puzzle. Old answers interweave with old one. They all reinforce one another. The clues are the question we ask. And the way the answers fall into a predetermined grid...well, that's our confidence that we are on the right track."
