A companion of a sort to last Friday’s post: In the 19th century, the linear idea of time became dominant. As Emily Thomas explains, that has had profound implications for how we experience the world…
‘It’s natural,’ says the Stanford Encyclopedia of Philosophy, ‘to think that time can be represented by a line.’ We imagine the past stretching in a line behind us, the future stretching in an unseen line ahead. We ride an ever-moving arrow – the present. However, this picture of time is not natural. Its roots stretch only to the 18th century, yet this notion has now entrenched itself so deeply in Western thought that it’s difficult to imagine time as anything else. And this new representation of time has affected all kinds of things, from our understanding of history to time travel.
Let’s journey back to ancient Greece. Amid rolls of papyrus and purplish figs, philosophers like Plato looked up into the night. His creation myth, Timaeus, connected time with the movements of celestial bodies. The god ‘brought into being’ the sun, moon and other stars, for the ‘begetting of time’. They trace circles in the sky, creating days, months, years. The ‘wanderings’ of other, ‘bewilderingly numerous’ celestial bodies also make time. When all their wanderings are ‘completed together’, they achieve ‘consummation’ in a ‘perfect year’. At the end of this ‘Great Year’, all the heavenly bodies will have completed their cycles, returning to where they started. Taking millennia, this will complete one cycle of the universe. As ancient Greek philosophy spread through Europe, these ideas of time spread too. For instance, Greek and Roman Stoics connected time with their doctrine of ‘Eternal Recurrence’: the universe undergoes infinite cycles, ending and restarting in fire.
Such views of time are cyclical: time comprises a repeating cycle, as events occur, pass, and occur again. They echo processes in nature. Day and night. Summer to winter. As the historian Stephen Jay Gould explains in Time’s Arrow, Time’s Cycle (1987), within the West, cyclical conceptions dominated ancient thought. It’s even hinted at in the Bible. For example, Ecclesiastes proclaims: ‘What has been will be again … there is nothing new under the sun.’ Yet, Gould writes, the Bible also contains a linear conception of time: time comprises a one-way sequence of unrepeatable events. Take Biblical history: ‘God creates the earth once, instructs Noah to ride out a unique flood in a singular ark.’ Gould describes this linear understanding of history as an ‘important and distinctive’ contribution of Jewish thought. Biblical history helped power linear ideas of time.
Cyclical and linear conceptions of time thrived side by side for centuries, sometimes blurring into one another. After all, we live through natural, cyclical seasons and unrepeatable events – birth, first marriage, death. Importantly, medievals and early moderns didn’t literally see cyclical time as a circle, or linear time as a line. Yet in the 19th-century world of frock coats, petticoats and suet puddings, change was afoot. Gradually, the linear model of time gained ground, and thinkers literally began drawing time as a line…
[Thomas explores four key developments that fueled the shift, chronography (the development of timelines), Darwin and the emergence of the concept of evolution, chronophotography, and theories in math and physics of a “fourth dimension” (then explored by Einstein and Bergson, Mary Calkins and Victoria Welby, Bertrand Russell, H. G. Wells, and so many others…]
… Today, conceiving of time as a line remains widespread. Timelines are everywhere: in the history of evolution, the history of video games, and the history of chocolate. There’s even a timeline of timelines. And the effects of this line of thought (pun intended) are still with us. Philosophers continue to debate the reality of past and future: just check out this bumper encyclopaedia article on ‘Presentism’, ‘the view that only present things exist’. Time-travel stories run rife. Back to the Future. Groundhog Day. The Time Traveler’s Wife. Historians have largely dropped Victorian faith in the progress of humanity, yet progress stories about particular areas remain. For example, take this timeline: it straightforwardly depicts technological progress over time. All these ideas are powered by the notion that time is a line. Were we to reshape our idea of time, perhaps these other ideas would also find themselves bent into new forms…

As we wonder at Yeat’s widening gyre, we might send echoing birthday greetings to Charles Louis de Secondat, baron de La Brède et de Montesquieu; he was born on this date in 1689. Better known simply as Montesquieu, he was a French judge, historian, and political philosopher.
Montesquieu is the principal source of the theory of separation of powers, which is implemented (if not always observed) in many constitutions throughout the world. He is also known for doing more than any other author to secure the place of the word “despotism” in the political lexicon. His anonymously published The Spirit of Law (De l’esprit des lois, 1748; first translated into English in 1750) was received well in both Great Britain and the American colonies, and influenced the Founding Fathers of the United States in drafting the U.S. Constitution.
