Existential intelligence can be defined as the ability to be sensitive to, or have the capacity for, conceptualizing or tackling deeper or larger questions about human existence, such as the meaning of life, why are we born, why do we die, what is consciousness, or how did we get here.
There are many people who feel that there should be a ninth intelligence, existential intelligence (A.K.A.: "wondering smart, cosmic smart, spiritually smart, or metaphysical intelligence"). The possibility of this intelligence has been alludedto by Gardner in several of his works. He has stated that existential intelligence might be manifest in someone who is concerned with fundamental questions about existence, or who questions the intricacies of existence. And while Professor Gardner has offered a preliminary definition as: "Individuals who exhibit the proclivity to pose and ponder questions about life, death, and ultimate realities," he has not fully confirmed, endorsed, or described this intelligence.
