What is Thomas Aquinas' definition of love and how does it differ from other philosophical perspectives on the concept?

Thomas Aquinas defines love as "to will the good of another." This differs from other philosophical perspectives on love, such as those of Plato or Aristotle, which may focus more on desire or attraction. Aquinas emphasizes the selfless aspect of love, where one's actions are directed towards the well-being and benefit of others rather than personal gain or pleasure.
