What's beneath the layers of a human.

If you ever wanted to experience what it's like to be a human without any form of cultural inculcation... to strip back all the layers of identity- race, religion, gender, sex, etc and exist as a baby (essentially)- to see what parts of 'you' are culturally instilled, what parts are instincts and natural tendencies, and what is actually left after all that is removed... Then unfortunately you would need to break the law and eat some form of psychedelic substance, however it can and has been done, and is possibly well worth it. :)
