Biopsychism supposes that every living being from bacteria up has sentience of a sort.
Plants don’t have a nervous system, or even neurons. But their cells, like many non-neural cells, do communicate with one another electrically, and there’s evidence that cellular channels in plants called phloem can transport not only sugars but also electrical pulses. Some plants show distinctly animal-like behaviour: witness the carnivorous jaws of the Venus flytrap, which even displays a primitive ability to “count” the number of impulses it senses before closing on an insect.

MORE IDEAS ON THIS
Lars Chittka of Queen Mary University of London and his colleagues have trained bees to manipulate a small ball into a hole at the centre of the “pitch” for a sugary reward. Bees can train one another in the task, and can find better solutions than their demonstrator: they don’t blindly follow r...

Plants can sense and respond to stimuli, as when flower heads move to track the progress of the sun across the sky. The South American “sensitive plant” Mimosa pudica, a member of the pea family, folds its leaves when touched and displays a kind of learning called habituation, where it eventually...

Conceiving a universe of possible minds can discourage human hubris, and advises erring on the side of generosity in considering the rights and dignity of other beings. But it also enables a literally broad-minded view of what other minds could exist. Mindedness needn’t be a club with rigorously ...

The challenge, then, becomes finding a way of thinking about animal minds that doesn’t simply view them as like the human mind with the dials turned down: less intelligent, less conscious, more or less distant from the pinnacle of mentation we represent.
We must recognise that the mind is ...

Until rather recently, philosophers and scientists have been reluctant to grant a mind to any nonhuman entity. Feelings and emotions, hope and pain and a sense of self were deemed attributes that separated us from the rest of the living world.

If other animals behave like us, that’s no basis to assume that they do so for the same reasons and with the same experiences and mental representations of the world. But as countless careful experiments like this study of pigs reveal ever more about the inner world of animals, there comes a poi...

We award pride of place in the hierarchy of bird minds to tool-using species, especially corvids (crows, ravens, rooks). The most masterful of them is the New Caledonian crow of the south Pacific, which will design and store custom-made hooks for foraging, and even make tools with multiple parts....

Bees can be trained to feel good or bad using flowers: blue ones carry a sugar reward, green ones don’t, but will a bee interpret an ambiguously blue-green flower optimistically or pessimistically? Again, behaviour seems to be coloured by experience: bees that have just been given an unexpected s...

The octopus is “probably the closest we will come to meeting an intelligent alien.” Octopuses interact with us, apparently with neither fear nor aggression. But in contrast to a dog or a chimpanzee, it’s hard to fathom what the agenda might be. They are great problem-solvers: they unscrew jars, n...

The octopus has a similar number of neurons as a dog, but instead of being mostly collected in a central brain they are distributed throughout the body in a ladder-like network. There is a centralised brain in the head, but more than half of the nervous system is in the arms, gathered into cluste...

To suppose that something like artificial consciousness will emerge simply by making computer circuits bigger and faster is, as one AI expert put it to me, like imagining that if we make an aeroplane fly fast enough, eventually it will lay an egg. Computers and AI are taking off in the “intellige...

Birds’ minds are scattered widely in mind-space, their differences and specialities tremendously varied. Some birds excel at navigation, others at learning complex songs or making elaborate nests.
Scrub jays are expert food storers, able to stash hundreds of caches around their habitat and...

It was long assumed that the anatomy of the bird brain (lacking a neocortex) is too different from ours to support any conscious experience, but recently those differences have been found to be less pronounced. How do you test, though, if another animal has a sense of self? One approach is to see...

Most of our fantasies about advanced alien intelligence suppose it to be like us but with better tech. That’s not just a sci-fi trope; the scientific search for extraterrestrial intelligence typically assumes that ET carves nature at the same joints as we do, recognising the same abstract laws of...
