What is the significance of agape in Greek love and how does it differ from other types of love?

Agape is a type of love in Greek philosophy that is selfless, unconditional, and focused on the well-being of others. It is often seen as a higher form of love compared to other types like eros (romantic love) or philia (friendship love) because it transcends personal desires and expectations. Agape is characterized by compassion, empathy, and altruism, and it is considered to be a more spiritual and universal kind of love that extends to all people, regardless of their relationship to the individual.
