/ˈpænθiɪzəm/
[noun] The belief that God and the universe are the same thing — that God is not a separate person or being, but is present in all things, all places, and all of nature.
The word 'pantheism' was invented in 1705 by an Irish writer who needed a label for a belief so old it had never had one.
The story of 'pantheism' begins not in ancient philosophy but in a pamphlet war in early eighteenth-century London. The Irish freethinker John Toland coined the English word in 1705, assembling it from two ancient Greek pieces: 'pan', meaning 'all' or 'everything', and 'theos', meaning 'god'. He joined these with the suffix '-ismos', a Greek word-ending used to describe systems of belief or practice, which passed through Latin as '-ismus' and into English as '-ism'. So the word means, quite literally, 'the belief that everything is god'.
The Greek root 'pan' is one of the most productive roots in the English language. It appears wherever we want to suggest totality or universality. The same root gave us 'pandemic' — via Greek 'pandemos', meaning 'of all people', from 'pan' plus 'demos' meaning 'people' — as well as 'panorama', from 'pan' plus 'horama' meaning 'view', and 'panacea', from 'pan' plus 'akos' meaning 'remedy'. In each case, the root carries its ancient promise of completeness and all-encompassing scope.
The root 'theos', meaning 'god', is equally ancient and equally busy in English. From Greek 'theos' came Latin 'theologia', which passed into Old French as 'theologie' and into Middle English as 'theology'. The same root gives us 'atheism' — from Greek 'atheos', meaning 'without god', formed from the prefix 'a-' meaning 'not' plus 'theos' — and 'monotheism', combining 'monos' meaning 'single' with 'theos'. Even the name 'Dorothy' carries it: from Greek 'Dorothea', meaning 'gift of god', from 'doron' meaning 'gift' plus 'theos'.
Although Toland invented the word, the idea itself is ancient and spans many cultures. The philosophy of the pre-Socratic Greek thinker Heraclitus, who believed a single divine fire permeated all things, has pantheistic qualities. The Hindu concept of Brahman — the ultimate reality that underlies all existence — resonates deeply with pantheistic thought. And the great seventeenth-century philosopher Baruch Spinoza, writing in Latin in his work 'Ethics', argued that God and Nature were one and the same substance, a position later thinkers would recognise as pantheism even though the word did not yet exist.
When Toland introduced 'pantheism' into English, it was initially used as a term of criticism — a way of accusing someone of dissolving God into the impersonal machinery of nature. Religious traditionalists saw it as barely different from atheism. But over the following century, particularly during the Romantic movement of the late 1700s and early 1800s, the idea gained admirers. Poets such as William Wordsworth and philosophers such as Friedrich Schelling found something deeply moving in the vision of a divine presence woven through rivers, mountains, and forests. The word shifted from an insult into a serious philosophical position.
Today, 'pantheism' sits comfortably in discussions of religion, ecology, and philosophy. Its appeal has only grown in an age when many people feel spiritual connection to nature without belonging to an organised religion. The word carries within it that original Greek architecture — 'all' plus 'god' — and in just three syllables manages to express one of humanity's oldest and most persistent intuitions: that the sacred is not somewhere above the world, but is the world itself.
