Suppose you had some undeniable proof of the Everettian or Many-Worlds Interpretation (MWI) of quantum mechanics. You would know, then, that there are very many, uncountably many, parallel worlds and that in very many of these there are many, many nearly identical versions of you – as well as many less-closely related “you’s” in still other worlds. Would this change the way you think about yourself and your life? How? Would you take the decisions that you make more or less seriously?
Consider Larry Niven’s 1971 take on that question. In a fitting contrast to the infinite multiplication of actions implied by the existence of a quantum multiverse, his story, “All the Myriad Ways”, consists entirely of a solitary police detective sitting alone and trying to puzzle out why a rash of unexplained suicides has accompanied the discovery of multiple, parallel universes. He begins to think that people see the existence of a world corresponding to every possible choice they might make as undermining the idea that they have any choice at all. In the end, he puts his own gun to his head – and all of the possible outcomes of that occur at once. I think there is more than one way of understanding this story. It’s not necessarily that people are inspired to take a fatalistic attitude by the knowledge of other worlds, it’s that just by recognizing that suicide is one of the possible outcomes, it becomes one of the things that will happen in some world or another.
But there may be a basic misunderstanding about quantum parallel universes lurking there. The splitting of universes has nothing to do with you and your decisions. Subatomic quantum events cause the universe to split, not you. You can, however, cause the universe to split whenever you make a decision by tying that decision to a quantum event. There’s an app for that. (Warning! This app only works if the MWI of Quantum Mechanics is correct.) Anyway, in the end, it’s not clear that it matters what causes the universe to split since it is splitting so often and so fast that it should create plenty enough parallel universes to cover all the decisions you could possibly make.

He released 33 albums and recorded over 400 of songs, earning two Grammys among seven nominations. Yet you probably don’t know who Leon Russell was. For some people he’s a vaguely familiar name they have trouble putting a face or a tune to. Many more have never even heard of him. Because despite his prodigious output, Russell also had a way of being there without letting you know. He was the front man whose real impact came behind the scenes. He was very present, but just out of sight.



Despite Vonnegut’s strong counsel to babies entering the world, kindness seems to be in short supply. Little wonder. Our news media portray to us a world of power politics, corporate greed, murders, and cruel policies which are anything but kind. Our popular forms of entertainment, much more often than not, are stories about battles that shock and thrill us and gratify our lust for bloody vengeance, leaving no room for wimpy, kind sentiments. Success is advertised to us as requiring harsh discipline, dedication, and focus, and kindness, it appears, need not apply. Even though we all like to give and receive kindnesses, they seem to play no role in our political, social, and cultural economies.

A few tall, dreamy-eyed Sikh men were on my plane to Lahore. 

I never met Jeremy Spencer, so I can only guess. I suspect he was searching for something. Only 23 years old, perhaps he was unhappy with himself, or the world around him. Perhaps he was scared and craving shelter from the storm. Perhaps he dreamed of what could be, or pined for a grand voyage. Maybe he just got lost.
In Homo Deus, the 2017 follow-up to his widely read Sapiens, Yuval Noah Harari dismisses the idea of free will in cavalier fashion. Contemporary science, he argues, has proved it to be a fiction. In support of this claim, he offers several arguments.
Once upon a time, in a beautiful but endangered forest far far away a prince and princess met, fell in love and married. They were blessed with a hundred children. “I wonder,” said the princess, somewhat exhausted from her exertions, “how best to raise our dear ones to care for each other and their beautiful forest home?” “I have heard,” replied her husband “that reading to children matters.”
