3. A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.

Metaphysics is the fundamental principles of the nature of things. One of the philosophers who wrote on metaphysical theories was Thomas Hobbes. Hobbes" philosophy on this subject in known as Materialism and this theory says that physical objects in space are all there is, even the mind. He tried to describe the universe as consisting of numerous constantly moving atoms. These moving atoms create thought and movement in humans and determined will or desire. The other two ideas of metaphysics are idealism and dualism. Dualism states that the mind is made of one substance and the body another. Dualists believe the mind and body work independent of one another.
