Vulgar Eros or earthly love and Divine Eros or divine love

Socrates, in Plato's "Symposium", explained two types of love or Eros—Vulgar Eros or earthly love and Divine Eros or divine love. 

1. Vulgar Eros is nothing but mere material attraction towards a beautiful body for physical pleasure and reproduction. 
2. Divine Eros begins the journey from physical attraction i.e. attraction towards beautiful form or body but transcends gradually to love for Supreme Beauty.  

This concept of Divine Eros is later transformed into the term Platonic love.
