Symbolic Interactionism, By George Herbert Mead And...

Symbolic interactionism is a sociological perspective that is influential in many areas of the sociological discipline. It is particularly important in microsociology and social psychology. Symbolic interactionism is derived from American pragmatism and particularly from the work of George Herbert Mead. Herbert Blumer, a student and interpreter of Mead, coined the term symbolic interactionism and put forward an influential summary of the perspective: people act toward things based on the meaning those things have for them, and these meanings are derived from social interaction and modified through interpretation. Sociologists working in this tradition have researched a wide range of topics using a variety of research methods. However, the majority of interactionist research uses qualitative research methods, like participant observation, to study aspects of social interaction and/or individuals selves. History Symbolic interaction was invented by George Herbert Mead and Charles Horton Cooley. Mead argued that people s selves are social products, but that these selves are also purposive and creative, and believed that the true test of any theory was that it was useful in solving complex social problems . Mead’s influence on symbolic interactionism was said to be so powerful that other sociologists regard him as the one â€Å"true founder† of the symbolic interactionism tradition.

His work has made a lasting impression on the world and our society. Wolfgang Amadeus Mozart was brought into this world on January 27, 1756 by his parents Leopold Mozart and Anna Marl Pertly In Salisbury, Austria.Mozart was the last to be born out of seven children, but unfortunately he and his older sister, Maria Anna, were the only two who survived in birth.

His sister was a gifted piano player by getting lessons from her father and Mozart learned how to play the piano as well by listening to Marias lessons, he also learned the violin by his father.Mozart accomplished these greats by the age of six and at that same age he and his family went on a concert tour. Mozart, his father, and his sister were on this tour together and at the end of their tour the family worked for an archbishops concert. Mozart wanted to escape from the archbishop but couldnt leave. His family went to Vienna and there was where he could finally be free from the archbishop. He moved to Vienna and instantly became a success. Mozart went on tour with his mother and later met a man, Fourfold Weber, and his starters, Alias, Constance, Sophie, and Josephs.Alias was a singer at the opera and she had a beautiful voice and had a natural sense of music. When Mozart saw Alias, who was 15, he Instantly fell In love with her and vowed to write arias that will make her famous. After he made that vow Anna Marie, his mother, became ill and It grew worse until July 3, 1778, when she passed away. Mozart later found out that Alias became famous and she ended all communication with him. After this ordeal to show his love for his crush it caused the family to go into debt. Mozart was forced o accept a position under the Archbishop to relieve the debt.Shortly In November of 1 780 he was asked to write an opera for the Munich carnival and he left his job at the Archbishop to write it. He was gone too long so they fired him. He later moved into the Weber familys house. His father didnt approve Mozart living quarters and wanted him to move out but something was stopping him from doing that the younger sister of Alias, Constance Maria Weber, stolen Mozart heart and he fell deeply in love with her. Constance was a singer like her sisters but was did not come famous like Alias because she was far from a diva.He found Joy in the love he had with Constance and they married In August 1782. In the later centuries people have called Constance mindless, a sex kitten, and a murderess. Despite all of these assumptions the only person that really knows how Constance was as a wife is 1 OFF having children like Mozart parents. The couple had six children but only two have survived after birth, two sons Karl Thomas and Franz Xavier Wolfgang. Mozart was ere ill in the year 1791 and later died in Vienna on December 5, 1791 at the age of hairy- five.He became ill so quickly that rumors started spreading that he was poisoned until a physician analyzed Mozart body and concluded that he died of heart failure caused by rheumatic fever and excessive bleeding. He was buried in a paupers mass grave along with other peoples bodies nobody knows where his body is now. Mozart had a short life and within his short life he managed to write 41 symphonies, 21 concertos, 13 serenades, 23 divertimento, 35 sonatas, and 12 duets. Nothing that one short lifespan Mozart had time to write and compose all of those pieces of music.He started his early work at the age of six when he wrote his first symphony. He wrote different symphonies for different instruments like the piano, Olin, French horn, clarinet, and bassoon. The orchestra was the main music group he wrote for. His music was sometimes accepted by society in different phases. When he wrote a new symphony it became popular but it wasnt memorable so the symphony stayed at the arena. Unfortunately, it took his death to make his music famous and popular. His wife continued to fight for his music to be in society and also other artists used is music as an influence for their work.Countless of composers and performers have played his symphonies and has given him credit for his masterpieces. In the 21st century his work is still being played and appreciated by countless orchestras and composers. Mozart will always be in music no matter Nat century and time. The new generation needs to be introduced Classical music ranging from Mozart to Beethoven. This kind of music can help expand a persons mind and cultural because of the way it was composed. I personally never paid attention to Mozart and all of the other famous composers until I took music appreciation in college.

Hamlet Soliloquy Reflection Essay Example

Hamlet Soliloquy Reflection Paper Hamlet, is a classic play still read throughout the world to this day. Starring the character Hamlet, and the royal family of Denmark, the play includes everything from murder, betrayal, Incest, love and turmoil. Shakespeare Is renowned for his writing, in Hamlet specifically the seven soliloquies. Soliloquies are monologue type speeches spoken by Hamlet generally and give the sense of the situation and feelings of Hamlet at the time. After carefully annotating the seven soliloquies, one can see the different states of mind, situations and characterizations of Hamlet. The deader can relate to the feelings Hamlet experiences regardless of the fact most readers have never been In situations as extreme as Hamlet. In the first soliloquy titled, O that this too too sullied flesh would . 2), Hamlet speaks about his fathers death and how he is feeling about his mothers new relationship with his Uncle.

However, to an extent I can relate because I can see from his point of view how awkward the situation is. I can relate in the aspect however of grief. Less than two months after his fathers untimely death, Hamlet still mourns his loss. However, Hamlet is crudely advised by his mother to Just get over it. She hopes that he can move on and I can relate to that. It Is hard to relate to a parent dying to breaking up with someone, but on a much smaller scale It seems very similar. Last year after I had a year relationship end, I was heartbroken, however he situation only became worse when after a few weeks; I felt a lot of pressure from my friends to just get over the situation. To put it like Shakespeare I am not a beast and I need time to mourn situations like these, time heals all wounds. The second soliloquy Is In Act 1, Scene 5 and Is again a monologue by Hamlet. The section Immediately follows the return of the newly dead king In the form of a split or ghost. This particular passage demonstrated the several emotions Hamlet was experiencing in this state of turmoil. The situation surrounding his fathers death has omen to light and Hamlet is faced with a decision of believing the ghost and avenging his fathers murder or forgetting the ghost ever spoke to him at all and sparing his uncle his life. Although I have never had to (seriously) debate killing someone I can certainly relate to the distress of having no Idea what to do In certain situations and contemplating a decision for hours before making one. Life Is full of compromises and I dont believe there is anyone out there who cant relate to having trouble making an important decision at least once in their lifetime that will have enormous mummifications for everyone around them. Whether it be, should I avenge my fathers murder and kill my uncle or something like should I stop being friends with someone or try and forgive them. These decisions could prove to haunt you In your future or your family as well as prove to be Instrumental In deciding your future character and The third soliloquy happens in Act 2 Scene 2. Hamlet at this point has decided he wants to avenge his fathers death and kill Claudia, but is having trouble and is getting frustrated at the fact that he cant plan and execute the killing as decisively as is father would have wanted. Hamlet is an interesting character because in no way is he either a hero or a villain. He has only the best intentions but regardless he still becomes determined to kill other. Regardless of what he does to convince himself to kill his uncle he cant and deep down I believe that shows that Hamlet truly is a moral person. Both Hamlet and myself are not perfect people. Neither of us are horrible people either, we strive to be the best and most responsible person we can possibly be and I think that is what makes his character so historically and emotionally appealing. In most literature you can see your protagonist as a clean-cut good guy. The fact that Hamlet breaks that stereotype and makes some decisions that many would see as immoral, makes the book that much more interesting. The Fourth of Shakespeare soliloquies begins with To be, or no to be: that is the question. As probably one of the most famous lines of the play, it truly is a great philosophical question about the decisions we make everyday. The quote itself found in act 3 scene 1 accurately describes Hamlets state of mind throughout the scene. Hamlet strongly debates the meaning of his existence at this point in time and whether it would be easier if he Just didnt exist, or if he were to commit suicide if that would simplify everything. Torn between making a decision, he decides he is a coward and that is why he cant kill himself. This whole concept is fairly relatable to the reader because, of course, sometimes its easier to Just want to disappear or die rather then face with the worlds challenges. However, like Hamlet discovers he must keep living because there is a purpose to his life we each resolve to plod on each day attempting to resolve or conflicts and struggles. The following two soliloquies come from the same section(3. 3). In this scene Hamlet definitively decides how he will handle the situation. First by addressing his mother in a cruel, not unnatural way about the situation and second by plotting the murder of his uncle Claudia. In the pursuit of vengeance Hamlet, postpones his killing until after he is done praying, so that rather than go to heaven his uncle can suffer as much as possible for what he has done. Vengeance is a strong emotion and everyone fantasize what it would be like to even the score once in a while, but as Hamlet will later learn, what goes around comes around. The last Hamlet soliloquy is the final act of vengeance for Hamlet. In an epic dual with his uncle, not only does he fatally wound Claudia, but also tragically himself. In the process his mother, the queen also becomes poisoned and essentially the entire royal family dies. At this point Hamlet sees the cost of vengeance. It is a moral we can all relate. For as it seems attractive to aggressively pursue an emotionally satisfying path to rectify a wrong, however, those paths often lead to repercussions one couldnt possibly imagine.
