What is the concept of unconditional love in Greek philosophy and how does it differ from other forms of love?

Unconditional love in Greek philosophy is known as "agape," which is a selfless, unconditional love that seeks the well-being of others without expecting anything in return. This differs from other forms of love, such as "eros" (romantic love) and "philia" (friendship love), which may involve desire or reciprocity. Agape is considered the highest form of love in Greek philosophy, emphasizing compassion, empathy, and altruism.
