WWW.uga.edu/ovpi/academic_honesty.htm WWW.uga.edu/ovpi/academic_honesty.htm Why Study Biology? Why “Perhaps the most fundamental value of a liberal Perhaps education is that it makes life more interesting…. It allows you to see things which the undereducated do not see. It allows you to understand things which the untutored find incomprehensible. It allows you to think things which do not occur to the less learned. In short, it makes it less likely that you will be bored with life and less likely that you will be a bore to those around you”. bore Kingman Brewster Jr., former President, Yale University.
