Chemical Analysis

I've been thinking a lot about how one could take the view that our human behaviors could be empirically explained by chemical analysis. For example, the amount of stress we feel has been shown by studies to be correlated to the amount of cortisol levels in the body (see here).

If one were to take the view that our behaviors and feelings were all simply (putting this lightly) the result of the chemical processes in our bodies, how incredibly dull and vapid our existences would be, that we are all just a result of reactions to stimuli, that, like the glory of sciences, we could actually model our experiences based on independent and dependent variables, correlated factors, and internal and external validities. The feeling of love, therefore, would just be based on a determination of finite factors leading to a wanted result -- it would be that easy... or easier, considering it is a complex result of multidimensional analysis, than actually finding a soulmate (which is arguably difficult, lol).

This isn't a mockery of scientific power. I'm a proponent for scientific innovation.  However, does this chemical analysis sound too... business-like? Perhaps.

Then the stars don't even matter
Now I'm filled to the top with fear
That it's all just a bunch of matter"
