I havn't been any more or less logical than arth1 has. He just has a world-view, a philosophy, the name of which is "Materialism" - you may heard the term. It's the view that all is matter and matter is all (pluse energy, space, time etc.)
A lot of people here have that worldview. Some worldviews are consistent. Some are inconsistent. You can tell the inconsistent ones because they lead you to absurd conclusions: such as a human life only has life if it's self aware, therefore it's justified to kill 1-hour old infants.
The question then is do you have the thoughtfulness to challenge the received wisdom? And say to yourself - "if this is my philosophy and this is where it has lead me, could it be that my philosophy doesn't have all the answers". But it takes a degree of intellectual humility to challenge one's self this way.
