Light is reflected from a rose in my garden. Focused by the lens in my eye, this forms an image on the retina, which in turn sets off a neural impulse along my optic nerve. This in turn travels to the visual cortex at the back of my brain, where a mental image is formed. I then see the rose. Activity arises in my pre-frontal cortex. Motor neurons in my spinal cord and arms activate the muscles needed to point the hose I am holding in the direction of the pot in which the rose is planted. The movements necessary to water the rose are coordinated by activity in the cerebellum which sits at the back of my skull just behind my brain stem. A swarm of bees approaches me. After my visual cortex registers this fact, the limbic system deep inside my brain activates the sympathetic branch of my autonomic nervous system, producing the ‘fight or flight’ response. My heart rate increases, I feel fear, drop the hose and run away.
Everything we do, experience, feel or think seems to either come from the brain or end up in the brain. Unsurprisingly, there is a strong temptation to claim that for all intents and purposes we are our brains, and this seems true to such an extent that philosophers have envisaged the possibility that for all I know I might be no more than ‘a brain in a vat’. They mean by this that a brain immersed in suitable nutrient fluid and connected up to a super computer feeding it appropriate neural stimulation could create all the ordinary experiences of everyday life: a world created within a brain. The story told above about the rose and the bees suggests that, provided I have the right inputs and they are coordinated with the outputs produced by the decision-making in my pre-frontal cortex, I could never know I was not simply a brain in a vat. (This of course is the basis for the film The Matrix)
Putting the brain in a vat hypothesis aside, it’s worth noting that neuroscientists and cognitive psychologists are quite happy to talk as if the brain produces ‘representations’ or ‘models’ of reality, suggesting that we come to know the world secondhand in the brain rather than in the world itself. To go back to the rose example, the account I gave indicates that I see the rose in my brain rather than in my garden, or at least that the only experience I can have of the rose is the representation produced in my visual cortex.
Something has gone seriously wrong here but it’s not immediately obvious exactly what it is. Two errors initially stand out. Read more »

The TV show Heated Rivalry arrives on cinema screens this week, transforming it from a short six-episode TV season into a 5-hour cinematic experience. I for one can’t wait to sit with an audience in a darkened theater and share in Shane and Ilya’s steamy romance. For those of us who love the show, it has always been an epic, monumental narrative, taking an outsized role in our lives. But why? The success of the show has created a kind of mystery—what about this story made it such an undeniable cultural force? Let us compare it to another cultural force which has recently entered the public imagination: Homer’s Odyssey. I am setting aside Christopher Nolan’s version of the story (which I found disappointing) to look instead at Homer’s text, which offers some surprising parallels with our favorite TV hockey romance.

I. The Practical Dilemma
Can you be betrayed by Donald Trump? If the Republican party indeed pays in seats for the war it watched its leader wage, it appears the reason is not the principled refusal of the American public to put up with authoritarian politics, but the perceived violation of its natural right to low fuel prices – the breaking of the president’s sacred promise to use his awesome powers only to hurt others. To call that a betrayal would be melodramatic; that concept derives all its force from a plausible prior belief in someone’s faithfulness or minimal ability to honor agreements, contracts, or oaths of office.
