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.

If a theory purports to explain everything, then it is likely not explaining much at all.

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.

I can't speak for others, but I find the fundamental idea that a life worth living is one during which one strives every day to become a better person to be compelling.

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.

I believe Stoicism can help anyone who takes it seriously and begins to practice it. It will help them flourish because it will provide them with a compass for navigating life, a general, flexible, framework to set priorities, and a set of techniques to achieve serenity and equanimity.

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.
