The neophyte scientist can be as dogmatic about unbelief as any believer can be about belief.
Yes that is true. However, I think this whole matter can be further simplified by looking at the nature of belief. Rather than arguing about God or any particular type of belief, the obvious and yet seldom considered fact is belief is just something in the mind, and that goes for non-religious ones too, not to mention belief is also just one type of mental activity.
The relationship between belief and experience no doubt comes from the desire to interpret the experience, so you either try to interpret everything in a simple way that is fairly rigid, or you go with any number of interpretations for simple experiences, or somewhere in between. I would not say to stop interpreting your experience, but atleast recognize when you are coming up with an interpretation, and why. This is where people get lost.
Just because a particular way of organizing the information has proved to be useful and relatively consistent, it doesn't mean it is set in stone. So I think the point about being dogmatic is more or less on the same page, I simply view it as limiting yourself to a certain way of thinking, a particular corner of your mind that you actually created yourself - whether you realize it or not.
People consider the matter of mind control under an external entity, they never consider it on the level of their own mind. This is why I don't really see the need to argue specifics, if someone is aware of their own thought process and is honest, the truth will naturally come through. On the other hand, it doesn't matter if you get very specific with the facts of a particular issue, if the way you think is limited in this way you're bound to be stuck in confusion. You may get very good at arguing a specific point of view, and there may be a lot of people who agree with you, (who are stuck in the same way) but how clear your thinking process is (and therefore how true it is) is another matter.
And even if it is very clear, your thinking and your experience is only that, your own. Of course this doesn't mean there's no truth in it, (wish I had a nickel everytime someone whined "That's YOUR truth!" as if that actually addressed the topic at hand in any way) but to put things in perspective its just what happens in this mind in response to reality at large. Most arguments are really not about what people think they are - they're really about ways of thinking (or who is right, so who should follow who) rather than what those thoughts pertain to. People are in effect talking about themselves, and nothing more. In other words, the topic becomes an excuse for one ego to combat another. Regardless of whose information is better or more complete, its really all about "me."
