Who has the monopoly on truth?

Lately I have been curious about the increasing ambiguity of truth. It seems that the more we discover, probe and theorize, the less we are willing to quantify and make objective statements.

Sure there are those questions which have never (and can seemingly never be) answered: Is there a god - big or little g?

There are questions which seem teasingly within our intellectual grasp: Is organized religion, ultimately, harmful to humanity in our increasingly global community?

And, then those which seem fairly certain, if not absolute: What is the best form of government? Does the possiblity of life on other planets exist?

What I seek to do is find connections between these categories. Like buidling blocks of truth, using what we know to uncover what we think we know, or what we simply don't know, is the most obvious (useful) method. However this technique has been curiously absent from the encompassing world of religion.

Certainly, I am only one of many who have had this thought - how can seemingly logical, rational throngs of people who label themselves believers continue to convince themselves of the existence of a personal god? What are the rational ramifications - how much must they ignore in order to sustain this belief? Are personal faith and rationalism mutually exclusive?

Feedback always welcome.
