Authorship is just one of the many challenges facing a deterministic worldview. Why give anyone credit for something they never chose to do? Source

Everyone at least acts as though they have the power to make their own decisions. Yet, when we reflect upon what we know about the natural world, it seems like this shouldn’t be possible. Instead, the thoughts you have should be cold, neurochemical reactions you have no control over. Similarly, chance must also be an illusion. If you win the lottery, the luck you perceive wasn’t really luck at all: turning the clock back would yield the same result over and over again.

Serious belief in the idea that “all things happen for a reason” is referred to in philosophical circles as Determinism. Determinism appears to be a natural consequence of the laws of nature and what we’re taught in physics. In this post, I’ll argue that from within a deterministic world — even one with trivial laws governing it — there’s no way to know if the world is truly deterministic. Along the way, I’ll also do a brief dive into why I don’t find the state of physics sufficient for figuring out if the world…
