"With hindsight, we see that the Soviet Union never had a chance of world domination, but we didn't know that then"

This quote by Ken Follett speaks to the idea that hindsight is 20/20. In the past, it seemed as though the Soviet Union had a possibility of world dominance, but in hindsight, we can see that this was never ever a sensible possibility. This quote works as a pointer that we can never genuinely know what the future holds, which our existing understanding of a situation might not be the same as our understanding of it in the future. It likewise speaks with the idea that our present understanding of a situation is typically restricted by our own biases and presumptions. We might think we know what will happen, however in truth, we can never make sure. This quote acts as a reminder to be unbiased and to consider all possibilities prior to deciding.
