He's talking about when people have experienced something and then someone tells them their experience wasn't what they knew it was but different. He's talking about when people go with that and take one someone else's words, contrary to what they know from experience, as truth. He calls it "the voluntary acceptance of other people's errors."

That's in "The Cancer Ward" by Alexander Solzhenitsyn, chapter 31, "Idols of the Marketplace." He's talking that way because he's getting operated on for colon cancer tomorrow. Usually he just thinks like that and stays quiet. He is of the opinion that he has gone along too much and it therefore full of shit.
