Subjective knowledge that cannot be made objective but where we have gone through the process of communicating details about this knowledge with others and from this we are able to reasonably conclude that others have similar subjective knowledge. Intersubjective knowledge can be created through a three step process. First, someone engages in introspection and then from this is able to better understand their own experiences. Second, this person explains to others how they can also introspect and better understand details about their own experiences. Finally, these people discuss their experiences and each of them is able to understand how other’s experiences relate to their own.
In my view, intersubjective knowledge includes phenomenal consciousness, free will, and a sense of morality.
