Maslow Knows Your Needs
"Abraham Maslow is known for establishing the theory of a hierarchy of needs, writing that human beings are motivated by unsatisfied needs, and that certain lower needs need to be satisfied before higher needs can be satisfied."

Maslow initially appears to combine creativity with spirituality as a single need.
