Humans are the only species who are capable of considering their own existence - of forming a self-identity. Intuition has historically been the wellspring of notions which address rhetorical questions about our identity and purpose. These concepts are embodied in classical religion. However, Darwin's publication of Origin of the Species in 1859, profoundly changed the nature of our identity. Suddenly, we became "just another part" of the natural world. The theory of evolution is well founded but is denied by a majority of people the world over. The Human Identity Problem discusses the consequences which face humanity if we continue to misconstrue our own identity.
