Anything that is intelligible.
Theology
Yep. Anything intelligible is open to scientific inquiry, i.e. within the confines of scientific endeavor. Unless, of course, one is closed-minded and thus either opposed to free inquiry or dedicated to a particular philosophy. Last time I checked it was evolutionists who prefer to use the law to choke out any mention of intelligent design in association with organized matter that performs specific functions. I guess they'd like to give former creationist tactics a whirl. Have at it, fellas!
