The statement can be interpreted as “the only duty a scientist has is to reveal the truth.” This means that a scientist should not have any other moral concerns or interests. A scientist’s primary duty is to uncover the truth behind natural events that occur around and within us. To do this, they need to carry out various experiments and researches which may involve some unethical procedures.

For example, animal experimentation could be considered immoral. Many pharmaceutical companies require animal experimentation to check the effects and side effects of drugs. Many people oppose animal testing as animals are exposed to cruel procedures and drugs which cause suffering and even death. However, without animal testing, we would not have discovered the medicines and treatments that we have today. For example, insulin was discovered when pancreases of dogs were extracted and studied. This discovery was critical to saving the lives of diabetics.

On the contrary, some may argue that scientists who work for the military often overlook the social impacts of their inventions. A prime example of this is Fritz Haber. He was a scientist in the German army. He proposed the use of toxic gas against enemy soldiers. Many chemicals were tested and then gaseous chlorine was used to cruelly kill the opposition. Soon, toxic warfare became famous around the world and different chemicals were introduced to aid the military. If Haber had thought about the consequences of his research, this would not have happened.

To conclude, it is important for scientists to reveal the truth. However, it is the humane duty of every scientist to consider the consequences of their researches. Science should be used for the betterment of humans and nature.
