I. Thinking about Thinking

Are animals conscious?

Is intellectual aptitude more closely related to brain structure or experience?

Is cultural behavior unique to humans or does it have a biological heritage?

Do men and women have the capacity to think in the same way?

Can thought be independent of the body?

Is mind a unity or a compilation of independent processes?

Is our consciousness independent of our language?

Can we find commonalities in the Eastern and Western approaches to consciousness?

Is consciousness unique to the human brain or can it be created in machines?
