This perception comes from a combination of personal experience and social integration. Kurtz argues that there are “two kinds of values ​​within human experience […] values ​​rooted in unexamined feelings, faith, customs, or authority […] and values ​​that are influenced by cognition and informed by rational inquiry” (73 ). He reveals that one can base one's values ​​on both immaterial beliefs and logical exploration, and suggests that the latter is more correct. However, what is right or wrong is a matter of cultural interpretation, and what is wise today may not be wise tomorrow. Consequently, it is how we use scientific results that matters more than what those results actually are. In the cloning example, the only reason why safety was considered an issue is the belief that we should not harm a human being, since we perceive our life as special. Despite this, Galileo was persecuted and Giordano Bruno was burned at the stake for suggesting that the earth revolves around the sun and not vice versa. This is now common knowledge, as our notions have evolved with science, but it does not change how the two of them, along with many others, were treated for going against the doctrine of their time. This shows that science influences how we actually look at things (eventually), but that we still use it according to our deeply held beliefs, creating divisions and tensions among our own individuals.
