Who wrote ' Crisis In Civilisation' ?

Answer 1

Rabindranath Tagore wrote an essay titled "Crisis in Civilisation" (link 1).

Of course, some people would spell that last word with a 'Z' instead of an 'S'. There is another books with the title "Crisis in Civilization" (link 2) by Singh Sawraj.

And if you accept further variations of that title, you're going to run into dozens of options...
