Emotions seem to have always had alot of value placed on them. History, in fact, has struggled with where exactly emotions should be placed on the significance scale. Stoics vs. Romantics, Men vs. Women, X vs. Y. In short, regardless of how 'significant' one so chooses to view emotions as, the whole idea of thought and action united contributes to the very essence, indeed, of what seems to make us human--capable of the greatest acts of mercy and the cruelest of injustices. Sponteneity, as it were, is the spice of life, non?

Seems like pharmaceutical companies, however, contribute a wide gamut of emotions to physio-chemical reactions of the brain and blood stream. Even if this were proven to be the case, I believe, given the history of emotions, that it would upset a great many people. Rapes us of our mystery; our individuality, and what else really do we have to call our own?
