Walt Whitman’s poetry frames scenes from 1920s New York in this film classic

Numberless crowded streets, high growths of iron, slender, strong,
light, splendidly uprising toward clear skies …

Billed as ‘a study of the modern Babylon-on-the-Hudson’, the short film Manhatta (1921) captures the rapidly developing cityscape of New York in the early 1920s. Made in collaboration between the US photographer Paul Strand (1890-1976) and the US painter Charles Sheeler (1883-1965), the piece is widely regarded as the first American avant-garde film, as well as the first of the non-narrative urban documentaries known as ‘city symphones’. The influential work traces the rich contours of a modern metropolis via a series of dramatic vignettes, as guided by Walt Whitman’s poem ‘Mannahatta’ from his collection Leaves of Grass (1855-1892). This version of Manhatta features a 2k digital restoration of the original 35mm film print, as well as a new score from the Illinois-based composer William Pearson commissioned by Aeon, with movements inspired by the film’s symphonic structure.

‘I hate giving you bad news’: when a daughter with breast cancer calls her mother

Danielle Hernandez is 30 and has Stage 4 breast cancer. As she calls her mother Violeta in Florida to deliver an update on her treatment from her home in Los Angeles, she oscillates between medical jargon and silver livings, with the more difficult pieces of information hidden in the subtext, only occasionally bubbling to the surface. This intimate conversation is captured by her roommate, the US filmmaker Lizzy Hogenson, in the short film Dani. Using a stop-motion technique that combines felt figures and claymation, Hogenson places her own veneer on the discussion, which is pierced by intermittent cracks of raw emotion, hard truths and silence. The result is at once affecting and distressing, as small moments of love, courage and pain spark and fade into uncertainty.

Creeping through mazes, repelling adversaries – the slow-motion smarts of slime moulds

To the naked eye, the organism Physarum polycephalum – commonly referred to as ‘slime mould’ – might seem an unexceptional creature, despite its bright-yellow glow, as its acellular existence is dedicated to tracking nutrients at a speed of 1mm per hour. But this protist’s surprising computational cunning becomes apparent when viewed in time-lapse, revealing a life form that seems to possess intelligence despite lacking a nervous system. Between 2009 and 2018, the UK artist and researcher Heather Barnett conducted a series of clever experiments in which she probed slime moulds’ capacities for forming complex tube networks and adjusting to obstacles. For this short film, Aeon Video compiled Barnett’s ‘creative collaborations’ with P polycephalum into a montage that builds in complexity, emphasising the slime moulds’ surprisingly sophisticated capacities for problem-solving.

Want to think for yourself? Start with an agonising state of doubt, says Kierkegaard

Influenced by Socrates’ sense of irony, the Danish philosopher Søren Kierkegaard (1813-55) came to believe that a state of doubt – disorienting and horrifying as it could sometimes be – was the cornerstone of a sound philosophical practice. This scepticism of objective truth and ardent belief in thinking for oneself is omnipresent in his pseudonymous works, in which his assumed names sometimes even spar with one another. While amusing, the peculiar literary device also undercuts any sense that the works were written by a voice of authority. In this video from the London Review of Books, the British philosopher and historian Jonathan Rée traces the theme of doubt in Kierkegaard’s life and work using his unfinished, posthumously published novel Johannes Climacus: Or a Life of Doubt as a starting point.

A handful of executives control the ‘attention economy’. Time for attentive resistance

From fitness tracking devices to search engines, it’s easy to think of personalised technologies as convenient shortcuts and useful tools for working towards goals. But, argues James Williams, a doctoral candidate at the Oxford Internet Institute and a former Google employee, the primary aim of personalised tech is to keep users coming back by any means necessary – and often in a way that encourages empty distraction. In this brief animation featuring audio from a 2017 lecture at the RSA (Royal Society for the encouragement of Arts, Manufactures and Commerce) in London, Williams makes the case that the consolidation of the ‘attention economy’ to just a handful of companies is an unprecedented and deeply fraught human experiment – and one that demands active, attentive resistance.
