So I bought this book written by a philosopher by the name of Edward Feser. His book is called "Five Proofs for the Existence of God". It can be found here: https://www.amazon.com/Five-Proofs-Existence-Edward-Feser/dp/1621641333
Anyhow, I read a few pages of it and generally he doesn't seem to be arguing for any specific religion simply for the concept of philosophically proving monotheism. However, when I told my Dad about this book he had strong objections because the book was written by a Catholic so he says that a Jew is not supposed to read such books. His objections mainly stem from the fact that he uses Greek philosophers arguments such as Aristotle and Plotinus and claims that Jews do not use Greek philosophy because it is pagan and foreign to us. To my knowledge this is not true because Rambam used Aristotle in his "Guide for the Perplexed", when I told him this he claims that Rambam had a special mind to separate the good from the bad (not sure what kind of argument that is) and that I don't have the mind for it and will get brainwashed and become a heretic by reading this book. He also objects because the author uses arguments put forth by Aquinas who was a Catholic and Augustine who was also Catholic. Lastly the author uses Leibniz who I believe was also a Christian.
My dad tells me that I should look for specifically Jewish philosophers who philosophically argue for the existence of G-d, problem is a lot of the arguments were effective in the time they were living and not as relevant today. This book was published rather recently and is considered some of the best proofs of G-d we have today. So yeah, should I listen to my dad and toss the book away?
