Why are you still trying to convince us, when it's obvious that none of us find anything compelling about your claims? Plus, you never tell us how this magical idea of your father's is supposed to work or what it has to do with how long it takes light to reach our eyes. Why does that keep coming up? What is the correlation between the speed of light and world peace? Did I miss something?
If you honestly believe his ideas can bring about world peace, why aren't you explaining that instead of trying to get people to read what appears to be a long, boring book. Why did he have to write over 500 pages to explain the dynamic discovery you claim he made regarding determinism?
There is a disorder called Reading OCD. The symptoms include reading a book in a certain way and/or reading the details over and over again, while trying to make sense of every word. What reminded me of this is that you told us you had just read the book your father wrote once again, looking for any little errors. While this type of OCD doesn't usually include just one book, perhaps it can, or perhaps you have some symptoms of something similar to what I mentioned. You say you aren't obsessed but it's very obvious to me based on all the time you've spent reading the book and trying to convince others to read the book over a period of many years that you are obsessed with this book. Aren't you the one who organized and put the book together for publication as well? I'm not trying to diagnose you with some type of OCD disorder, but your symptoms are a bit similar to OCD in some respects. If not OCD, you at the very least suffer from an obsession. I honestly feel bad for you. It must be awful to be so frustrated over an obsession with a book that very few people want to read.
My comment regarding this isn't meant to be the least bit insulting. It's meant to be helpful, an effort to encourage you to at least speak to a mental health counselor about how many years you've tried to convince people to read the book, how much time you've spent here and in other places trying to convince others to read the book, and how many times you've read the book yourself etc. To me, it appears like an obsession that is robbing you of some better ways to live. Let someone know about this and then ask if it's a healthy way for you to be spending your time. It's not a weakness. It's not something you chose. I guess your father and his work influenced you to be obsessed with his writings, so of course it's not your fault that you're stuck with this obsession.
You don't need to respond to this post as I'm just trying to help you understand how I think you come across to others. All I'm doing is giving you my perspective on what seems like an unhealthy obsession over a book.
I actually read about 60 pages of the book yesterday, as I found the first 3 chapters online in an easy to read format. Your father was obviously an intelligent man, but he was also extremely wordy, often repeating himself over and over, while never getting to the point, imo. He criticized academics for not taking him seriously due to his lack of formal education, but a few of them at least tried to listen to him. I agree that a lot of highly educated people aren't nearly as smart as they think they are and some look down on those with less education. Having lots of letters after one's name doesn't always equate with intelligence, but believing you've unlocked the secret to world peace is also quite an arrogant claim.
Some of it reminded me of the book I read a few years ago called, "The Cruelty of Free Will". That author discussed how Bill the thief couldn't help himself, unless something stood in his way and that we should understand that, but that book never suggested there was some great discovery that would end violence etc. He just said we shouldn't judge people as they are unable to help who they are. Other than prison reform so that these people are treated more humanely, I don't think there is a thing we can do to keep society safe from violent people.
Plus, do you or did your father have any understanding of brain disorders like PTSD, psychopathy, schizophrenia or bipolar disorder? These brain malfunctions have no effective treatment at this time and while most people who suffer from them with the exception of psychopaths are harmless, some commit violent acts. How is your father's discovery, which you haven't explained going to cure these people of these brain diseases? This is all part of science. Do you not believe in medical science? Medical care changes as new research comes up with more effective treatments, as I mentioned before. We have vaccines that despite the anti vaccine fools, have prevented a massive number of deaths and disabilities since the beginning of my life. The polio vaccine came out when I was in grade school and we couldn't wait to get it. You father criticized education in his book, but without higher education, we'd have no progress when it comes to things like vaccines and cures for diseases. Sadly, mental illness has been neglected and so we still don't do a good job of helping those who suffer with brain disorders, which is how I prefer to refer to mental illnesses.
And, btw, it's not the price of the book that prevents me from reading it, if I felt it was worth my time, I'd buy it and read it. I could barely read the 50 or so pages without getting a headache due to the repetitious nature of the book and how it was beginning to sound very irrational. Plus I currently have enough Amazon digital dollars to get the book for free, but there are other books I'd rather use them on.
I know you mean well, but your father did not discover the secret way to bring about world peace, anymore then the Baha'i religion did. The prophet of that religion seemed to mean well too, especially considering it was started in Persia as, imo, a way to make the Muslim religion more gentle and reasonable. Sadly, to this day Baha'is are subject to persecution in Iran. Humans have a long history of persecuting those who don't believe what they do when it comes to religion. So, the Baha'i prophecies didn't work out so well and however well your father's intentions were, there is no way he found a valid way to make the world a better place including establishing world peace, an end to violence and even according to his book, an end to careless driving.

Those are all irrational claims. Sorry you don't see it.
I hope you can get some help with this obsession and live a more enjoyable productive life. As we used to say back in the idealistic hippy days of my youth, Peace, love and happiness to you. Yeah. We thought we could establish world peace too, but we were just idealistic kids who didn't understand human nature that well. I will do my best to leave this discussion and I hope the other posters will be charitable to you if they feel they must continue engaging with you. Better yet, I hope you will find a better way to spend your time.
