The Stoic discipline of action, which is connected to the virtue of justice, says that we ought to treat others fairly and we should engage in social and political activity. This is further supported by the Stoic idea of cosmopolitanism, and by the famous "circles of concern" identified by Hierocles, who counseled that we should refer to other people as brothers and sisters, to constantly remind ourselves that we are members of the same human family.

In my mind, there is no reason why Stoicism shouldn't become as popular as Buddhism, especially in the Western world, where the dominant culture, Christianity, itself absorbed a large number of elements from Greco-Roman Stoicism.

If you are a Christian, you can still practice Stoicism and think of the Logos as the Word of God. If you are a secular person, an agnostic or an atheist, you may treat the Logos as "Einstein's god," that is the factual recognition that the cosmos is ordered according to rational principles, without which science itself wouldn't be possible.

"Fate permitting" is a standard Stoic phrase meant to remind ourselves that planning things is up to us, but the ultimate outcomes are not under our control. It helps us to develop an attitude of equanimity toward the universe. We should very much try to change things for the better, that's the whole point of the Stoic discipline of action.

The Stoics thought that a fundamental insight into human life is that some things are up to us and others are not, the famous dichotomy of control. Up to us are our judgments, decisions, and actions; everything else is not up to us, because it is influenced by external factors.

What the world needs is more compassion; love in the broad sense, and use of practical reason to solve human problems. What it needs less is ideological and religious fanaticism, of which, unfortunately, there currently is aplenty.

We still live in a world of such gross injustice and inequality, that only privileged people like ourselves can afford to think of eros and art as top concerns in life. They are important, for sure, but I think it's high time to shift priorities around, away from selfish indulgence, and toward more concern for the wellbeing of so many others who suffer atrocities, injustice, and famine, all over the planet.
