“Good” and “evil” are very ambiguous terms and can only be personally defined by an individual's beliefs and values. It's said that our values ​​are defined primarily by our upbringing, but what if they were more neurologically rooted than we thought? Neurophysiologist Dr. Roger Wolcott Sperry won the Nobel Prize in 1981 for his discoveries on the functional specialization of the cerebral hemispheres, in which he studied the cognitive effects caused by cutting the longitudinal fissure that divides the two hemispheres of the brain. In the region of the longitudinal fissure, neural tissue, called the corpus callosum, connects the two hemispheres of the brain and allows communication between the hemispheres. His studies gave rise to the theory that individuals, even though they need both hemispheres connected to function properly, could be classified as being "right brain" or "left brain" dominated, referring to to their respective hemispheres. Additionally, his findings suggest that certain functions and abilities are controlled primarily by one side or the other of the brain. The right hemisphere is said to be creative, reflective, intuitive and more spiritual; while the left hemisphere is considered objective, analytical and motivated by hard facts and science. Neither way of thinking is wrong, just different. In Oryx and Crake, by Margaret Atwood, the protagonist continually asks the question of whether science has gone too far. Given the uncanny similarities and parallels between Jimmy's world and our current world, the question was not only for the characters, but also for the reader. What is the limit, how much is too much? Based on one's core values, an individual can decide...... middle of paper ...... capable. At the same time, be aware of your impact and don't let your thirst for knowledge force you to neglect its effects on humanity and nature. It's not wrong to have either mindset, but we need both to maintain a balance. Works Cited “10 reasons to avoid GMOs”. - 10 reasons to avoid GMOs. Institute for Responsible Technology, nd Web.
