Our bodies โ€“ the physical, biological parts of us โ€” and our minds โ€” the thinking, conscious aspects โ€” have a complicated, tangled relationship. Which one primarily defines you or your self? Are you a body with a mind or a mind with a body? Maryam Alimardani investigates.

Caption:
Look at your hand. how do you know it's really yours . it seems obvious, unless you've. experienced the rubber hand illusion. in this experiment, a dummy hand is placed. in front of you. and your real hand is hidden. behind a screen. both are simultaneously stroked. with a paint brush. no matter how much you remind yourself. the dummy hand isn't yours,. you eventually start to feel like it is,. and inevitably flinch. when it's threatened with a knife. that may just be a temporary trick,. but it speaks to a larger truth:. our bodies, the physical, . biological parts of us,. and our minds, the thinking,. conscious aspects,. have a complicated, tangled relationship. which one primarily defines you. or your self . are you a physical body that only. experiences thoughts and emotions. as a result of biochemical interactions. in the brain . that would be a body with a mind. or is there some non-physical part of you. that's pulling the strings. but could live outside . of your biological body . that would be a mind with a body. that takes us to an old question. of whether the body . and mind are two separate things. in a famous thought experiment,. 16th-century philosopher . renรฉ descartes pointed out. that even if all our physical sensations. were just a hallucinatory dream,. our mind and thoughts . would still be there. that, for him, was the ultimate proof. of our existence. and it led him to conclude that. the conscious mind is something separate. from the material body. that forms the core of our identity. the notion of a non-physical consciousness. echoes the belief of many religions. in an immaterial soul. for which the body is only . a temporary shell. if we accept this, . another problem emerges. how can a non-physical mind have. any interaction with the physical body . if the mind has no shape, . weight, or motion,. how can it move your muscles . or if we assume it can, why can your mind. only move your body and not others . some thinkers have found creative ways. to get around this dilemma. for example, the french priest . and philosopher nicolas malebranche. claimed that when we think about. reaching for a fork,. it's actually god who moves our hand. another priest philosopher . named george berkeley. concluded that the material world. is an illusion,. existing only as mental perceptions. this question of mind versus body. isn't just the domain of philosophers. with the development of psychology. and neuroscience,. scientists have weighed in, as well. many modern scientists reject the idea. that there's any distinction . between the mind and body. neuroscience suggests that our bodies,. along with their physical senses,. are deeply integrated . with the activity in our brains. to form what we call consciousness. >from the day we're born,. our mental development is formed. through our body's interaction. with the external world. every sight, sound, and touch create. new maps and representations in the brain. that eventually become responsible. for regulating our experience of self. and we have other senses,. besides the typical five,. such as the sense of balance. and a sense of the relative location. of our body parts. the rubber hand illusion,. and similar virtual reality experiments,. show that our senses can easily. mislead us in our judgment of self. they also suggest that our bodies. and external sensations. are inseparable from . our subjective consciousness. if this is true, then perhaps descartes'. experiment was mistaken from the start. after all, if we close our eyes. in a silent room,. the feeling of having a body. isn't something we can just imagine away. this question of mind and body. becomes particularly interesting. at a time when we're considering. future technologies,. such as neural prosthetics. and wearable robots. that could become extended parts. of our bodies. or the slightly more radical idea. of mind uploading,. which dangles the possibility . of immortal life without a body. by transferring a human consciousness. into a computer. if the body is deeply mapped. in the brain,. then by extending our sense of self. to new wearable devices,. our brains may eventually adapt. to a restructured version. with new sensory representations. or perhaps uploading our consciousness. into a computer might not even be possible. unless we can also simulate a body. capable of delivering physical sensations. the idea that our bodies are part. of our consciousness and vice versa. also isn't new. it's found extensively . in buddhist thought,. as well as the writings of philosophers. from heidegger to aristotle. but for now, we're still left. with the open question. of what exactly our self is. are we a mind equipped with. a physical body as descartes suggested . or a complex organism . that's gained consciousness. over millions of years of evolution. thanks to a bigger brain and. more neurons than our distant ancestors . or something else entirely that. no one's yet dreamt up . .
