Question: Can the non-existence of God be proven? I see how a person could believe – purely based on rational argument – that God's existence cannot be proven, thereby becoming an agnostic. On the one hand, many non-theists criticize theists for believing in a deity strictly on faith, claiming that there's no rational reason to believe in a deity. Most theists, however, would probably reject that, saying that they have rational reasons for their beliefs too. On the other hand, atheism seems just as unproveable as theism. Yet atheists claim that their beliefs are based on reason, rather than emotion or faith. As a result, aren't the atheists covertly relying on faith? Or can atheism be proven purely based on reason? Why not just admit that we don't know? Also, practically speaking, isn't the agnostic basically the same as an atheist?
Question: Does being rational mean having faith in reason? I'm a high school student in a religious school. Many of my classmates claim that my belief in a knowable reality, science, and reason is merely a form of faith. So how can a person validate his own reason and senses? How can a person know that they are reliable means of knowing reality – unless he uses them and thereby engages in circular reasoning? My classmates claim that God is the only way out of this puzzle: God checks our reasoning by verifying and opposing our various conclusions. How can I respond to their arguments effectively?
Question: Is philosophy deduced from axioms? Often, I hear people claim that philosophy – particularly Ayn Rand's philosophy of Objectivism – is deduced from axioms. Is that right? Personally, I don't see how that can be: How can anything be deduced from "existence exists"? But in that case, what's the purpose of the axioms?
