This doesn’t claim the status of definitive opinion. I’m just throwing it out as an idle muse.
I have a series of classic novels that were released under the generic title Books That Have Changed Man’s Thinking, and I wonder just how much books are capable of changing the development of human culture and behaviour. It seems to me that books are capable of influencing attitude, and attitudes are certainly different now than they were fifty or five hundred years ago. But it further seems to me that when the chips are down, what comes to the fore isn’t attitudes but human nature; and that doesn’t seem to have changed in all the centuries of known history, in spite of all the books.
I’ll muse on.
