All mammals know they exist. The brain inside of a brain. Who am
I? I figured it out - although I'm sure I'm not the first. Well,
here you go. You know when you get a ''gut'' feeling or you just
''know'' something - like, ''I know I exist''?
The sense of taste and ''gut'' feelings (deep emotions) are
literally located DEEP within your brain. You deeply feel that
you exist because, just like a deep craving for your favorite
food (or drug or perhaps certain emotional states) - are all
happening together in the Insular Cortex - the brain within your
brain.
''I exist'' is about as much of a gut feeling as anything else.
it's hard to shake it.
Since all mammals have an insular cortex, this means that all
mammals have self-awareness. They know they exist.
