by hearing Phineas Gage’s story what did we learn?
the brain is the source of mental life and damage to the brain can have a profound effect on who we are and what we are.
who named the ‘Astonishing Hypothesis?
Nobel Prize-winning biologist, Francis Crick
what does Astonishing Hypothesis mean?
you, your joys and your sorrows, your memories and your ambitions, your sense of personal identity and free will, are no more than the behavior of vast nerve cells and their molecules.
where can Dualism be found?
every religion and philosophy
what are the parts of Duality for humans?
we are part material, spiritual, separate, mental, and psychological.
who was the most thoughtful and articulate defender of dualism?
philosopher, Rene Descartes

he argued that humans respond to environmental stimuli
who claimed that our behavior’s far too complicated for that and that we can’t be machines?
Rene Descartes and Noam Chomsky
what is a method of doubt?
the claim that we don’t feel like bodies
who said “There’s one thing you can’t doubt. You can’t doubt your own consciousness. You can’t doubt your own existence”
Rene Descartes

“I think, therefore I am”
what does Rene Descartes mean when he said “I think, therefore I am”?
that you could doubt that you have a body, but you can’t doubt that you have a mind.
what raises the possibility of dualism?
as people age their consciousness follows their bodies, if the mind and body are separate it raises the possibility of dualism
