I read an interesting paper on this phenomenon years ago (that we use morality to justify, not reason). A summary (not written by me): According to Haidt's (2001) social intuitionist model (SIM), an individual's moral judgment normally arises from automatic 'moral intuitions'. Private moral reasoning—when it occurs—is biased and post hoc, serving to justify the moral judgment determined by the individual's intuitions. http://www.mc.edu/campus/academics/BIO/emotional%20dog%20rational%20tail.pdf http://www.mc.edu/campus/academics/BIO/emotional%20dog%20rat...
