I think love is something made up by society to explain to them their need and dependence of other humans. There are three major theories on love and the one I think is the most accurate is the attachment theory. The attachment theory was introduced by professor Bowlby and built on by Ainsworth. Basicly the attachment theory is saying that love is the continuation of the emotional bond between infants and their mothers. Shaver further conceptualized love as a combination of three biologically based behavioral systems: attachment, caregiving, and sexuality. Each has its own set of different behaviors and functions. All three systems can be mixed up by "non-optimal social-learning experiences." And they may take on different time courses, which may be the reason for love's different subtypes and developmental stages, as they are identified by others. For example, Hatfield's "companionate love" includes attachment and caregiving but not necessarily sexuality, whereas "passionate love" emphasizes only sexual attraction. In the last few years the Attachment theory has become one of the most popular perspectives currently influencing research in close relationships.
             I think most of society got the concept of love from religion, however, love is a word whose meaning has been spun around a lot in our time and in many ways it has lost connection with the divine meaning. In today's world, loving someone means making them feel good, emotionally or physically. But the way that the bible puts it across it's the fundamental idea of love binding a man and woman together for life, which is difficult work, so in a culture like ours that promotes self-gratification, we've chosen to overlook it.
