Yeah, those unemotional Stoics.
"Whoever then understands what is good, can also know how to love", a statement by Epictetus combining the emotional commitment of justice with love towards others. Marcus Aurelius extended this to all that one meets: "Accept the things to which fate binds you, and love the people with whom fate brings you together, but do so with all your heart", and Seneca The Younger noted that "Joy comes to us from those whom we love even when they are absent".

There's a lot of love going around among these unemotional Stoics. Why is that?
