In modern times, human beings have become susceptible to psychological illnesses. Nietzsche and Freud both give different explanations for the origin of diseases. Freud blames it on our libido and its erotic appetite which goes against current standards as a disease. While Nietzsche accuses the revolt of the slaves of morality of preventing us from acting according to our animal impulse. Both diseases are quite similar as they appear to have the same origin from each other. Freud presents an interpretation of how individuals become ill. It states that when individuals have an unpleasant idea, they repress these ideas in their subconscious. Here the idea grows, festers and can lead to neurotic behavior. Through psychoanalysis Freud was able to alleviate these problems but he also came to the conclusion that these repressed ideas were actually not the root of the problem but in fact the real cause is the sexual frustration of the patient's childhood or adolescence. Individuals then become ill when the libido is unsatisfied and refuses to accept that reality can offer them satisfaction. The result is that individuals fall into fantasies to adequately achieve wish fulfillment as they cannot seem to find satisfaction in the real world. You can avoid becoming neurotic by channeling these desires into works of art. But if they fail, they will fall into a neurotic state. While we are in this neurotic state we begin to regress to our childhood, when obtaining pleasures was easier. Therefore, escape into illness is the easiest way out as it allows an individual to simply bypass society's problems, moving to a state where he can immediately gain pleasure. The disease Nietzsche writes about is bad conscience. Nietzsche states that human beings... in the center of the paper... fall into these diseases because they desire to obtain pleasure. Freud's neurosis is easier to see in this light. He states that the reason individuals fall into neurosis is that, unable to satisfy their libido, individuals withdraw from society and focus on their fantasies. This allows them to achieve pleasure. For Nietzsche, individuals choose to contain themselves, because they are unhappy on earth and are told that by limiting themselves they will be able to obtain salvation in heaven. Although the stories are different, modern society has made it difficult for people to achieve pleasures, so they get sick trying to achieve them. Both philosophers identified diseases that appear in modern society. Although each philosopher has a different story about the origin of the disease, both bad conscience and neurosis seem to be described as the same disease.
