Freud. Few people are as well known, notorious, and iconic as early 1900's theorist and psychologist Sigmund Freud. The notoriety of the man who created Fruedism is undeniable, but is the validity of his theories as substantial as the man's popularity? Arguably the most well known development of Freudism comes from Freud's theory that one's personality is bifurcated into three parts: the id, the reservoir of our personality that craves instant pleasure and gratification, the ego- which serves as the personality's decision maker-and the superego, our sense of mortality containing right and wrong. Although the theory is well known and well developed, the idea does is not a certainty. Those who refute Freud's postulates feel that one's mind is not as separated as Freud proposes, rather, the personality of a given person has a strong sense of continuity and consistency. To some, the idea of a personality being split between an "angel" and "devil" is far-fetched and illogical, but the psychoanalytical advocates of Freud's theory vouch for the idea's portrayal of the conflict amongst a person's conscious and subconscious. Regardless, no matter what direction a person approaches Freud's philosophy, the idea is revolutionary and stirs curiosity as to how a person's personality functions. Like it or love it, thanks to Sigmund Freud, people are left learning or questioning more about the human personality, which can only lead to more knowledge of the mind.
