The Stoic revival has picked up pace in recent years, with people looking for something more substantial than the material hedonism that has come to fill the space vacated by the retreat of organised religion. Indeed, although more expressly rational, Stoicism has been compared to Buddhism, particularly Zen Buddhism, for being based on fluids concepts and flexible principles rather than blind faith and rigid dogma. But the similarities do not end there.

Desire and Attachment

According to the Buddha’s Four Noble Truths, the cause of all suffering is desire, and the natural way to eliminate this suffering is the Noble Eightfold Path. The first division of the Noble Eightfold Path is “right view”, or maintaining perspective on reality.

Similarly, the Stoics taught that we ought at every moment to be rational. Unfortunately, we are too readily waylaid from reason by unwise attachments and the destructive emotions to which they give rise. These attachments dangle the promise of pleasure or happiness but really offer only slavery—whereas, if only we could see it, nothing leads to pleasure and happiness as surely as reason and self-control.

In the words of Marcus Aurelius, which are all the more remarkable for coming from an emperor:

Keep in mind how fast things pass by and are gone—those that are now, and those to come. Existence flows past us like a river… Nothing is stable, not even what’s right here. The infinity of past and future gapes before us—a chasm whose depths we cannot see. So it would take an idiot to feel self-importance or distress. Or any indignation, either. As if the things that irritate us lasted.

God, Fate and Evil

Stoic physics is indebted to Plato’s Timaeus, in which the philosopher Timaeus claims that God’s creation is itself a god. Human souls, being fashioned from the inferior residue of the world soul, are aligned with the will of God. But once implanted into a body, they are overwhelmed by sensations and affections, which they can only overcome through appropriate nurture and education.

Like Buddhism and Advaita Vedanta, Stoicism rejects a separate divine sphere, arguing instead that God is infused in all things, including in us, who therefore share in His nature. We are, as Epictetus often reminds us, a part or extension of God:

In conversation, exercise, discourse—do you remember that it is God you are feeding, God you are exercising? You carry God around with you and don’t know it, poor fool.

The Stoics were essentially pantheists, like Baruch Spinoza, who thought of God and creation as one and the same thing. And like that other great 17th century philosopher, GW Leibniz, they believed that the universe is a rationally ordered whole, and that everything that happens within it, if only we could see it, happens for the best of possible reasons.

Hence, our fate has already been determined: instead of rebelling against it, we should be content to play the role that has been assigned to us. We are, said Zeno [the founder of Stoicism], like a dog tethered to a cart: the wise person runs smoothly alongside, whereas the fool struggles and strains but is dragged along anyway.

This echoes the Hindu concept of dharma, which can be translated, loosely, as “duty”. When Krishna addresses Prince Arjuna in the Bhagavad Gita, he is not persuading him to fight so much as telling him that he is going to have to fight regardless:

Fettered by your own task, which springs from your nature, you will inevitably do what you in your folly do not want to do.

Chrysippus, who succeeded Zeno and Cleanthes at the head of the Stoa, argued that evil is the inevitable consequence of nature’s goodness. For instance, many of the bones in the human skull are light and thin, improving it overall but by the same token leaving it vulnerable to blows. Evil presents us, as it did the hero Hercules, with opportunities to test and hone ourselves—and also a motive, for what would it mean to be good in a world without evil?

In Samkyha-Yoga, the world was created to purify souls by providing them with experience, and, in time, with liberation. To put this more poetically, the world was created to show consciousness to itself. The doctrines of karma and moksha[liberation] could not hold in a world without evil.

Salvation, for the Stoic as for the Hindu, is to embrace life to the point of accepting fate, and so to become as one with the world. In Indian terms, it is to achieve moksha, that is, liberation from maya [illusion], dukkha [suffering], and samsara [the cycle of death and rebirth].

In the Encheiridion, the Stoic Epictetus compares life to a landfall during a much longer sea voyage back to our homeland, and warns us not to get so caught up by the fruits and flowers as to forget about the ship.

Cosmopolitanism

Philosophers debate whether karma theory is a firm basis for morality, or just an appeal to naked self-interest.

One way around this problem is to broaden the scope of karma to include thoughts as well as actions, so that the system becomes impossible to game. Doing the right thing for the wrong reason is not the same, and does not feel the same, as doing it for the right reason. According to the Great Forest Upanishad, the truly virtuous act is the one that is desire-less. Like the Stoic archer, one must concentrate on doing the right thing, to the best of one’s ability, without being attached to the outcome. For it is from attachment that life and misery arise.

The Buddha had another way around the problem, which is to deny the metaphysical distinction between the self and others so that helping others is the same as helping oneself. The Stoics, too, believed that all human beings form part of a single organism. Just as our eyes, ears, and teeth each have a role to play in our body, so we too each have a role to play in society, even if it is only to serve as a warning to others. “Remember” says Seneca, “that he whom you call your slave sprang from the same stock, is smiled upon by the same skies, and on equal terms with yourself breathes, lives, and dies.”

To live selfishly is fundamentally self-defeating. To feel alive and happy, we need to have a sense of working with others, for others—because, like ants and bees, that is the kind of creature that we are. If we do not contribute to our community, we will feel disconnected and depressed. In a word, we will feel dead—and, in truth, might as well be.
