You should try to write about what the characters in the book Symposium by Plato think about love in general. But you don't have to go into detail about every single perspective of love. You should also write about what love meant in their society at that time. Try to connect to important historical terms etc. Try not to make a summary of the book. Try instead to pick one or a few ideas and really expand upon them. Use formal language. No footnotes are needed because the only sources that is needed is the book Plato - Symposium
