This is one of the most difficult questions for mankind. Centuries have passed by, relationships have bloomed and so has love. What is love? But no one can give the proper definition of love. To some, Love is friendship set on fire, for others, Maybe love is like luck. You have to go all the way to find it. No matter how you define it or feel it, love is the eternal truth in the history of mankind. Love is patient, love is kind, it has no envy, but the over all question remains, what causes it? Through case studies and informational journals, we will be able to attempt to understand the causes of this love. This literature review will examine three sources: The Physics and Chemistry of love by Kanika Gswami, Sexual arousal ‘very different’; confirmation of questionnaire methods by the American psychological society, to help in the further understanding of this topic. It is found that love is closely related to the chemistry of the brain but it is still fair to believe that love is a feeling that comes from the heart.
In The Physics and Chemistry of love, Kanika Goswami speaks of how the common symptoms of love; such as, sweaty palms, shaky knees, and the occasional restlessness; are caused by a chemical found in the brain called Phenylethylamine. This specific chemical is released through simple actions such as the meeting of the eyes or holding hands. She finds that the discovery of this molecule is an important feat for all humanity as now chemists can truly create “love potions”, which would allow us to fall in love with the next person we see upon taking it. Now, some people may agree that the moral issues presented with this new discovery can be disputed against. For example, some may argue that the purpose of falling in love would loose all meaning. Others would see it as a simple and quick way to find happiness. In her article, Gswami states, “Love, like all things bound to the universe, is non existent without some amount of physics and chemistry...
