A very simple philosophical question that can trigger an existential crisis. Do not sue me if you do get an existential crisis, that was probably a pre-determined event… or is it?

I mean I personally don’t see why the universe is non-deterministic, every time you flip a coin, or roll a dice, if you knew the initial conditions and the forces applied to the coin/dice, the atmosphere, wind, etc., you could predict the results with absolute certainty. And free will does not exist. But that’s just my view on this matter, who knows what the universe really is.
Now see, if you’re looking at things from a biological point of view, it’s important to recognize the forest from the trees. A few trees are, well, just a few trees. But a great many trees together constitutes a forest, and becomes more than the sum of its parts. I feel the same way about the human brain. Yes, it’s a series of electrical and chemical impulses, but there are so many of these working in tandem that it becomes exponentially more complex, akin to ever-advancing computer technology. It’s complex enough that we think, we talk, we make decisions. And those decisions aren’t based solely on instinctional drive, and can even be made in opposition to them.
It’s true that human behavior can be accurately predicted based on an individual’s natural tendencies, but there are never any guarantees. There’s always a choice, a chance to veer off course. Decisions can be prudently made after careful research, or made on a frivolous impulse. Maybe you even realize that you would ordinarily take one action in a given situation, but do the exact opposite. You consciously chose to ignore your first impulse. If free will is an illusion, it’s a damned convincing one.
