All knowledge is provisional.

As a teacher over the years I've collected quite a few resources including text-books.
My thinking was that..."This is a good text. I'll use it with my own kids and grandkids."
I taught across the curriculum so I had books from a range of subjects.
Some have stood the test of time.
I could teach to the subject using most of the Maths texts despite some changes to the way that subject is now taught.
But the Science texts are pretty much redundant.
Even though a lot of the material is still accurate things like planetary info, periodic tables etc have undergone serious revision.
It would confuse the reader who wouldn't be sure what was right and what was inaccurate
History/Social Studies texts from the sixties and seventies have at their centre a UK/Empire bias.
Indigenous culture gets a page or two...if that.
Atlas and Geography texts have the same issues as Science. Yugoslavia and Czechoslovakia no longer exist, and despite Putin's 'valiant' attempts the Soviet Union is now several independent countries. There are many new countries in Africa and Asia.
Yep,...knowledge is only what's known and accepted at the time, and subject to change at a later date.
