Introduction: “You have to believe in free will. You have no choice”. Seriously, if our Universe is a clockwork Universe, where causality rules absolutely (as both Newton
I will argue that if causality means anything, then everything is predetermined and therefore there is no free will. Causality rules – a cause causes an effect which in turn becomes the cause for a later effect which is hence the cause for an even later effect, and so on down the line. It’s an unbroken causality chain starting from an initial set of fixed conditions. The past determines the present which determines the future. If you knew the past to an absolute infinite amount of detail, then you know the future to that same degree of infinite detail, and free will doesn’t enter into things.
Continued from yesterday’s blog…
Now let’s take the case of human conception, through to blastula, embryo and foetus. I think one can agree that a human doesn’t need to make any decisions for the first nine months, while still in the womb. Ditto the nine months following birth, and probably another nine months after that. But sooner or later, that baby or infant will make its first decision that’s not based on fundamental body needs like ‘deciding’ to go to sleep or wet it’s diapers.
The question is what is fundamentally different about the nature of the infant before it can make its first free will choice or decision and just after? The brain, the brain chemistry, the neural nets and pathways, would be seemingly identical. The only thing I can think of is that the infant and infant’s brain/mind is receiving an ever steady input of sensory data, ultimately enough to allow the infant to make decisions – the baby wants scrambled eggs, not soft-boiled eggs.
The ever increasing absorption of external stimuli may provide the ultimate need or desire to make choices, but it doesn’t provide the mechanism. Ultimately I don’t think there is a free will mechanism as everything is predetermined, like the computer simulation of “Life”. But does it really matter whether or not you have actual free will or the illusion of free will? It doesn’t alter how you live your life and the expectations of those unknown choices you’ll make between now and when Mother Nature makes that final choice on your behalf!
So far I’ve been muttering on as if you came to a metaphorical fork in the road and had some sort of free will to pick one path, or the other path; maybe neither path - or maybe not, if causality rules the universal roost.
There’s no free will solace in the Many Worlds Interpretation of reality; in coming to that fork in the road, because all paths, all possible choices, are enacted as the universe splits to cater for each and every one. You may think you picked one path – the high road, the low road, or the path least travelled, it makes no difference – and thus could pat yourself on the back for having free will and acted upon it, but in actual fact it was, ditto, an illusion. All paths were taken, in one world you took the high road, in another the low road, in a third world the road in-between, so no cigar, you do not pass ‘go’, you do not collect $200 free will dollars as there was no free will exhibited.
I do have some unanswered questions. Say you have to decide between wearing that green dress or that red dress to – whatever. You set those thought chemical/physical wheels in motion. I’m not quite sure how the chemical/physical processes stay focused on the issue at hand. I mean, what if you hence decide to make scrambled eggs – nothing to do with the original green dress/red dress decision! Perhaps that’s a part of the ‘disease’ we collectively call mental illness.
Then there’s the old hairy chestnut of if there is no free will, can people, should people, be held accountable for their behaviour? The fact that people are, obviously suggests that society as a whole has voted for the concept of free will. Whether that has ultimately a religious base (God gave us free will) I know not, but I’d bet - probably.
Quite apart from that deterministic clockwork Universe scenario – what was set in motion at the Big Bang event 13.7 billion years ago, those initial fixed conditions, the set of particles and the laws and relationships that governed their interactions and evolution past to present to future – there are other slightly less plausible scenarios that also limit your free will if they reflect true reality.
For example, if you appear in your dreams as a character, or as a character in someone else’s dreams, your (or someone else’s) dream world representation of you, if questioned (not that that’s possible of course) about your free will, well you would reply that within the dream you were a part of (not that you would know you were a participant in a dream) that you were exhibiting free will. But of course it’s actually the dreamer’s mind that’s pulling the strings, and thus the characters (such as you) in a dream just dance to whatever tune is played out for them. No free will.
Dreams (wetware) aren’t the only form of virtual reality. There’s software, and computer generated simulations, like, say video games. The characters within, as per the dreams scenario, would tell you if they could that their actions exhibit their own free will. But of course that’s not true; the programmer and ultimately the player dictate the action and tell the character what to do. Again, there’s no free will actually exhibited by the characters.
Now, ask yourself what if our reality is actually the product of a higher reality wetware or software? That is, we’re dreamed or simulated but ultimately generated beings akin to the beings we dream about or we create via our software. We’re actually characters in someone else’s dream (let’s hope they don’t have an alarm clock set) or the product of someone (something) else’s software (let’s hope they don’t hit the delete key). If that’s so, then, we got no free will. We waltz to their wetware or software tune.
Lastly, although according to legend God gave us free will, let’s say for argument’s sake that there’s an afterlife and that we go to Heaven. Do you have free will in Heaven? That is, could you, of your own free will, commit a sin in Heaven?
Conclusion – Regardless of what society believes, I believe free will is an illusion. Everything is preordained, much like that next scene in the movie you’ve already seen a half-dozen times before. You know what’s coming next and the characters you’re observing have no choice in the matter – no free will. Well, maybe that’s what life, the Universe, and everything is – something already recorded and set in stone. Or, like that example I gave above, “Life”, perhaps we’re a computer program or simulation with relationships and rules all set in motion, perhaps for the edification or amusement of that extraterrestrial computer programmer in the sky!

As a result he suffered a ruptured bladder and snuffed it, getting a Darwin Award in the process. That was a hell of a way to die for king and country!
