So I've wrote this book that explains how the external world; the existence of an objective reality outside of our perceptions; is a logical impossibility. In other words, it's not like what Leo does; I'm not merely arguing and presenting evidence for why we are unjustified in assuming such a reality - no, this is something different. I'm actually showing you, logically, why there can't even exist a possibility of such a reality. Now, I'm posting here because for the next 5 days, the book is FREE in the kindle store, and I thought, given how much weight Leo has given this idea of no objective reality, that you might be interested. https://www.amazon.com/Refuting-External-World-Goran-Backlund-ebook/dp/B00NOXW8QE I hope it's helpful to somebody.
