We believe what we wish to believe in religion, science or anything else. If I chose not to believe either Vort or Ov then it doesnt matter what they say. If I believe the world is my own creation then behold it is. Anyones debate or jabber on the subject is just for my entertainment since I know I created you as a hobby. I have set the boundries of my belief and you can say what you want. My beliefs will remain.
You may convince me I am wrong but it will be due to my feelings on what you say, not whether it is correct or incorrect.
Of course you are free to think I am wrong but that is just more entertainment for me if I refuse to feel your argument for separate existence is worthwhile considering.
Everything we believe is based on feeling and it doesnt matter if its science, religion or philosophy. Of course most people will give consideration to the views and beliefs of others if they are convincing or have convinced enough people to bring peer pressure to bear.
