imagine a human without qualia and other mental states. Such a being cannot have conscious experience. I call them a philosophical zombie.

[David Chalmers @DavidChalmer]

A Philosophical zombie is physically identical to a normally functioning person on the outside and the inside.

[David Chalmers @DavidChalmer]

Philosophical zombies can’t experience qualia. it screams when stepped on but wouldn’t feel pain.There’s nothing ‘it is like’ to b a zombie.

Property dualism is the concept that we are made of one substance but ther exists different properties.
Mental and physical properties

[David Chalmers @DavidChalmer]

Physical properties are the likes of wetness, softness and pain.
Mental properties are the likes of beliefs and emotions.

[David Chalmers @DavidChalmer]

Qualia are phenomenal properties of experience.
In smart words it’s the experiential quality of what it is like to be you.
