Stoic Philosophy in a 5-Bullet Nutshell

The Roman emperor Marcus Aurelius is the most famous Stoic.  He is depicted here with kind eyes that convey the Stoic ideal of unconditional love.

So you’ve heard people talking a lot about Stoicism recently—an ancient Roman philosophy that supposedly has astonishingly relevant and well-developed advice to offer us today in the 21st century.

You’re not sure what all the fuss is about, but you’re skeptical.  You just want to learn a little more—quickly.  Why waste time on a set of 2,300-year-old Greco-Roman ideas if they’re just going to turn out to be weird and irrelevant?

Maybe you heard a really powerful quote attributed to an ancient Stoic teacher, or maybe you read about Stoicism’s modern revival in The Economist‘s new offshoot magazine or Massimo Pigliucci’s lovely New York Times op-ed, or maybe you came across Stoic Week on social media—an annual event where scientists at the University of Exeter teach people all over the world to practice Stoic mindfulness, and then analyze the impact that it has on their lives.  You’ve heard people calling Stoicism the Western counterpart to Buddhism, and saying it has all the same great ideas without the weird metaphysical baggage.

Somewhere in all of this, has something caught your attention?

Then without further ado, here are the five main pieces of Stoic philosophy.*

It’s perfectly okay if only one or two parts of Stoicism interest you.  Even people who call themselves “modern Stoics” are rarely fully committed to all five points.

Three Pillars of Practice

An infographic by Leah Goldrick, explaining the three pillars of Stoic ethics.

The Stoic’s practical world view is based on three highly idealistic beliefs about who humans are and who we can (and ought to) become.

  1. Tranquility: There is a rational component to our emotions.  By paying attention to our thoughts (which are the only thing we can really control), we can reduce anxiety and achieve consistent tranquility and joy.This “therapeutic” component is by far the most popular part of Stoicism—many people focus on it exclusively.


  2. Virtue Ethics: Being an excellent person is infinitely more important than pleasure, wealth, fame, etc.  Time is precious: we are all mortal, and our task on earth is to strive to be the best people we can be by embodying the four Socratic virtues as far as possible:
    • Self-Control
    • Courage
    • Justice and Benevolence
    • Wisdom

    The pursuit of virtue as the highest good tends to be emphasized by people who are more committed to Stoicism as a holistic world view.


  3. Love all Humanity: Human virtue finds its highest expression in fellowship with other humans: anger and revenge are irrational, but helping one another is good and natural.  We ought to practice extending the natural affection we feel for our family to all humanity (yes, even our enemies!), as the working out of justice and benevolence.The Stoics believed in the equality of all people, and they taught that even fools have the “seeds of virtue.”

The ancient Stoics did not believe that we could ever actually attain these ideals perfectly—mortals rarely or never become true Sages—but they found great value in pursuing their understanding of what a truly wise and virtuous person would look like.

Two Pillars of Theory

All schools of ancient philosophy, but especially the Stoics, saw ethics as the most important part of scholarship.  But they also recognized that your broader world view would have a big impact on the form your ethics takes.

Stoicism, then, emphasized the role that science plays in informing morality:

  1. Providence: Classical Stoic theory is rooted in the idea that we should “follow Nature,” because the universe is rational, and humans are created to pursue a particular kind of excellence.  They had a scientific notion of God that is somewhere in between atheism and theism as we know it today.For more on this, and to see how modern Stoics navigate what some would call outdated theological ideas, see my post on Zeus for Atheists.
  2. Physics: More generally, the Stoics saw all the branches of knowledge (logic, physics, and ethics) as deeply interrelated.  Our study of nature always has something to say about how we should live.

The Classical Texts

The reality is that few people would be excited about Stoicism today if they didn’t identify strongly with the Greek and Latin books that have survived from Stoic authors.  Stoic literature is full of rich metaphors, candid descriptions of daily life in the Empire, and heated debates with their philosophical rivals (especially the Epicureans).

Almost all the ancient Stoic literature has been lost.  The three majors books that survive (among many other fragments and essays), though, are chalked full of remarkably beautiful statements and sentiments.  While these books aren’t canonical scripture, contemporary Stoics love to quote these authors and discuss what their ideas mean for modern scenarios:

Seneca is my personal favorite—he is widely considered to be the best writer of the three, and his interpretation of Stoicism puts special emphasis on joy. Here’s a taste of his style:

Do this above all, dear Lucilius: learn how to experience joy.  Do you now suppose that because I am removing from you the sweetest of beguilements, I am taking away many pleasures?  Not at all: what I want is that gladness should never be absent from you.  I want it to be born in your own home—and this is what will happen if it comes to be inside you.  Other delights do not fill the heart; they are trivial feelings that merely smooth the brow.

Moral Letters, 23.3.

And here is a nugget from Marcus, whose poignant aphorisms are all targeted at calling our mind to a high standard of personal excellence and benevolence toward others:

We have come into being to work together, like feet, hands, eyelids, or the two rows of teeth in our upper and lower jaws.  To work against one another is therefore contrary to nature; and to be angry with another person and turn away from him is surely to work against him.

Meditations, 2.1.


So there is your taste of Stoicism! If you like what you see, there are lots of resources for learning more—starting with the excellent posts over at Stoicism Today. For some accessible, long-form reading, I’ve particularly enjoyed Irvine’s Guide to the Good Life: The Ancient Art of Stoic Joy (2008) and Donald Robertson’s Stoicism and the Art of Happiness (2013).

^Obligatory disclaimerStoicism was the preferred philosophy of a huge number of people across the ancient Roman world, and it survived as an active school for nearly 700 years. Any bullet-point summary will of course be a simplistic caricature!
