A review by mveldeivendran
Astounding Science Fiction, October 1941 by John W. Campbell Jr.

4.0

How to confuse someone with the elemental time travel story?

This short story has its own closed über confused loops with some holes left by the author unanswered however backed by some epistemological notions. Read it if you want to experience such a possible life in the world of science fiction. Concepts of Free will, Retro causality, futuristic utopian visions and many more.

"If God created the world, who created God?
Who wrote the notebook? Who started the chain?" It's all bugging me.
