I am more interested in the physics Walter Russel has to offer.
Anone who is mainly interested in the "physics"-part I can just recommend the 3rd edition of the HSC and not the 4th. As the 4th is a remastered version of the 1st edition. And the differences in content is quite profound, especially the physics part, as a lot of his work in this direction has been done at the end of his life (e.g. the NORAD work). Also a lot of important drawings in this relation were drawn quite late and so are only in the 3rd edition.
I still wonder, why they made the fourth edition based on the first and not on the 3rd.
I don't really get it as "philosophy" though. To me, a philosophy has to include arguments that follow logically, with a premise and conclusion of some sort.
To me. I discovered, that you can get a "logical" argument for everything, as absurd as it sounds. So I realized that logic has an approvement for the truth of approximately 0%!
But what I also discovered is, that the truth lies within you. And that if you hear or read the truth you will get an inner feeling telling you, that this is the actual truth. Without any logical justification needed, which as I already mentioned would anyway mean nothing...
It would just be a justification for your brain to believe this argument. But you still wouldn't know if it's the actual truth. As the brain can never know it.
Real knowledge can only come from within. And all the books etc. can only help you discovering the truth that already lies dormant within oneself, ready to become discovered.
In this sense. I wish us all to discover the truth within oneself.
