which is the best SCIENTIST or PYSCHOLOGIST??

For me, I think one of the best Psychologist is Abraham Maslow. He is known for his conceptualization of a "hierarchy of human needs" and has been said to be the father of humanistic psychology. His fundamental contribution on putting human needs in a hierarchy has given him a lot of rewards and recognition. He contended that humans have a lot of needs that are instinctoid, that is, innate and even postulated in arranging these needs chronologically according to their potency and in such a way that one is necessary for the other. Abraham Maslow has just a great mind to realize as basic yet fundamental as this.
