Everything is Mutable

We often have this silly notion of “immutable facts”. But what does this mean? What is the significance of this thought? My thoughts:

Immutable

Mutare: to change, to move, to mutate. From “mew” which means “to move”.

Thus from a very basic perspective:

To move is to change.

And to change things is to move things.

Why do we desire an immutable world?
