Chapter 15
Science in the 19th century challenged the faith of the enlightenment. Charles Darwin argued that life was a constant change and a struggle for survival. He believed evolution occurred through natural selection which created conflict with Christians. Karl Marx also highlighted pain and struggle in life and human civilization and in turn the start of socialism. Sigmund Freud concentrated on human emotions and thought that our conscience influences human sexuality and behavior such as aggression. In the 20th century, physics created a new view of science. Findings such as light bending, matter, and energy are equivalent and space can warp light. All of these scientists formulated the birth of our modern science today.
