What is the purpose of life? - To survive, to love life, to gain wisdom, to create things of value. And finally, to transcend our biology.

What are feelings? - A transcendent measurement between our personal aesthetics and our external social environment as reflected by our thoughts. The resulting emotions drive our will to act guided by our level of wisdom.

What is our destiny? - To raise our level of consciousness through a deeper knowledge of truth, aesthetics and wisdom.

What are we? - Machines based on biological technology - a 'natural' form of nanotechnology. We have bodies that can animate in the world and senses that can guide us. Between the muscles and senses is an information processing system that discovers sufficient meaning from the sensory patterns to coherently guide our muscles to survive & begin acquiring wisdom.

How should we live? - We should balance (according to our aesthetics) the processes of survival, creating values for ourselves and others, acquiring wisdom and loving life.

What is truth? - Physical reality as it traveled through what we understand as 'time' from the past to the present moment. see here
