more pernicious than the one it replaced. Science and rationality were the new "God," but instead took the form of a deity that was colder and less comforting than before. Nietzsche exerted a significant impact on the development of psychology in general, but he specifically influenced an approach that emphasized an understanding of life from a personal perspective. In exploring the various needs of the individual about the ontological conditions of being, Nietzsche asserted that all things are in a state of "ontological privation," in which they long to become more than they are. This state of deprivation has major implications for the physiological and psychological needs of the individual. Edmund Husserl (1859–1938) While Kierkegaard and Nietzsche drew attention to the human issues that needed to be addressed, Edmund Husserl's phenomenology (Husserl, 1960, 1962; Moran, 2000) provided the method to address them rigorously. He contended that natural sciences assume the separateness of subject and object and that this kind of dualism can only lead to error. He proposed a whole new mode of investigation and understanding of the world and our experience of it. He said that prejudice has to be put aside or 'bracketed,' for us to meet the world afresh and discover what is absolutely fundamental, and only directly available to us through intuition. If people want to grasp the essence of things, instead of explaining and analyzing them, they have to learn to describe and understand them. Max Scheler (1874–1928) Max Scheler (1874–1928) developed philosophical anthropology from a material ethic of values ("Materielle Wertethik") that opposed Immanuel Kant's ethics of duty ("Pflichtethik"). He described a hierarchical system of values that further developed phenomenological philosophy. Scheler described the human psyche as being composed of four layers analogous to the layers of organic nature. However, in his description, the human psyche is opposed by the principle of the human spirit. Scheler's philosophy forms the basis of Viktor Frankl's logotherapy and existential analysis. Martin Heidegger (1889–1976) Martin Heidegger (1889–1976) applied the phenomenological method to understanding the meaning of being (Heidegger, 1962, 1968). He argued that poetry and deep philosophical thinking could bring greater insight into what it means to be in the world than what can be achieved through scientific knowledge. He explored human beings in the world in a manner that revolutionized classical ideas about the self and psychology. He recognized the importance of time, space, death, and human
