In the Soc 101 class, we were required to read Civilization and Its Discontents by Sigmund Freud. While studying for my final, I came across a very interesting idea he quotes. He believes that the necessities in life are food and love.
Freud describes the importance of love and states the only thing that causes "social anxiety is the loss of love" (85). Love is the only thing that a man opens his heart to and it is the worst thing he can loose for it can do the most damage!
Freud even believed that love was just as necessary as nourishment was! Just thought I would share my findings :)
