Extended mind

Extended mind is a theory in philosophy which says that your mind can be connected to things outside your body – like a computer, a smartphone, or notes written down on paper - and those things can help you to think and remember. So if you wanted to remember a lot of stuff, like phone numbers or list of things to do, you could use a notebook to write it down, and your mind would be “extended” beyond your body to that notebook to help you remember.
