When my mother died her world died with her. What she saw, how she saw it, and what it meant to her no longer exists. The same will happen when I die. The world that I take so seriously, that feels so real, will disappear when I do.
This is not solipsism, there is a “real” world of matter and energy out there. But what I experience and what you experience are fundamentally different. Sure there are broad overlaps, and these are what allow us to communicate and to co-exist, but the reality that we are each so convinced of, and so attached to, is made up.
Remember this the next time you get into an argument about whether that shirt is green or blue – you are both right.
Remember this the next time you get into a bigger argument about bigger stuff too…
