“Morality can consist solely in the courage to make a choice.” This quote from Leon Blum conveys what ethical judgment is. It means making a choice about what is wrong and what is right and the choice made influences further activities. If one chose that the activity is right, then that activity would be continued, but if one chose the choice that the activity is wrong, then the activity could not continue, so there would be no further production of knowledge. It is human beings who decide and make a choice since science and art are just a tool. But since there are no scientific methods in the world to decide what is right and what is wrong due to the absence of a universal ethical code, what I consider ethical may not be ethical for another person. So, the process by which people perceive situations or their beliefs about what is ethical and unethical determines emotions and thus actions are ultimately taken. But to what extent should humans consider ethics when carrying out experiments? The question of knowledge raised by the question would help explore the question of knowledge in the areas of knowledge: natural sciences and art. To generate knowledge in science it is necessary to conduct experiments. But first it is important to know what knowledge is. Knowledge is anything that is supported by evidence and to support it you need to first conduct experiments as proof. To gain knowledge about the disease syphilis, the medical experiment called the Tuskegee syphilis experiment was conducted. Using reasoning as a method of knowledge, doctors would seem logical for them to use black men as laboratory equipment, since it is possible to know the causes and symptoms of syphilis. It's actually helpful to know about syphilis... middle of paper... is the situation extremely miserable? No, there would be no time to think about ethics. For example, a nine-year-old girl named Kim Phuc ran naked from her village after the napalm attack. The photographer was undecided whether to take the girl's photo and continue his career or go and help her as her entire body, skin and clothes were burned. Not only with the photographer, even with the publisher the situation was the same. Since there is an ethical issue behind it, the publisher had to sacrifice the girl's privacy to publish the photo in the newspaper. However, ethical judgments did not limit the publicity of this Vietnam War photograph since the photograph was taken and was published in the newspaper. Indeed, this photograph was the most inspiring and, acting as evidence, changed the view of people living in the United States against the war.
