Freud once saw his father walking through the street when a man came up to his father, cursed him, and pushed him into the mud. Freud's father quietly stood up, picked up his hat and walked away without doing anything about the situation.

Freud was unsure of exactly which area he wanted to study in, but he knew from reading Darwin that he wanted to know more about the world around him. Along with Darwin's work, Freud heard an essay written by Wolfgang von Goethe that made him strive to study medicine. The essay described how nature allows its children to discover and explore its mysteries (Klagsbrun 22). Sigmund Freud took that to heart because in his time era, there was more mysterious than knowledge of science. Another influence, or idol, to Freud was Ernst Bruke, a professor of physiology.

Without fully knowing a subject, it is not as easy to thrive in the matter. The most important lesson that Bruke taught Freud was to seek scientific truth for himself and not for fame (Klagsbrun 5). Fame could have set Freud off track if would have let it go to his head. Freud then followed Bruke's words, and simply accepted the fam...
