“Morality can consist only in the courage to make a choice. » This quote from Léon Blum illustrates well what ethical judgment is. It is about making a choice between what is bad and what is good, and the choice that has been made affects subsequent activities. If the choice that the activity is good was chosen, then that activity would continue, but if the choice that the activity is bad was chosen, then the activity could not continue and so there would be no more knowledge production. It is humans who decide and make a choice because science and art are only a tool. But since there is no scientific method in the world to decide what is right or wrong due to the lack of a universal ethical code, what I consider ethical might not be ethical for another person. Thus, the process by which people perceive situations or their beliefs about what is ethical and unethical determines the emotions and therefore the actions that are ultimately taken. But to what extent should humans consider ethics when conducting experiments? This knowledge problem raised by the question would make it possible to explore the question of knowledge in the fields of knowledge: natural sciences and art. To generate knowledge in science, experiments must be conducted. But first it is important to know what knowledge is. Knowledge is anything that is supported by evidence and to support it, initial experiments must be conducted as proof. To gain knowledge about syphilis, the medical experiment called the Tuskegee Syphilis Experiment was conducted. Using reasoning as a means of knowledge, it seems logical for doctors to use black men as laboratory equipment because the causes and symptoms of syphilis can be known. It is actually beneficial to know about syphili... middle of paper ......the situation is extremely miserable? No, we wouldn't have time to think about ethics. For example, a nine-year-old girl named Kim Phuc fled her village naked after the Napalm attack. The photographer was faced with a dilemma whether to click the girls' photo and continue his career or go and help her as her entire body, skin and clothes were burnt. Not only the photographer, but also the editor. As there is an ethical issue behind the editor, he had to sacrifice the girl's privacy in order to publish the photo in the newspaper. However, ethical judgments did not limit the publicity of this Vietnam War photograph as it was taken and published in the newspaper. Indeed, this photograph was the most inspiring and by serving as proof, it changed the views of people living in the United States against the war..
