He believes that this idea justifies the use of infants and people who are mentally ill for painful and lethal scientific research instead of animals who are superior to such. ( Singer 2) Evidently, Singer does not know the purpose of scientific research. We spend millions perhaps even billions of dollars a year on scientific research for the benefit of humans. So it would be very contrary to use humans and risk harming them, when our ultimate goal is to save and benefit their lives. Steinbock agrees that, “If we can free human beings from crippling diseases, pain and death through experimentations which involves making animals suffer, and if this is the only way to achieve such results, then I think that such experimentation is justified because human lives are more important than animals lives,” a point which Singer fails to acknowledge.

Even though, Singer may not agree, intelligence is definitely a factor in how we treat others. Just take a look at society, anywhere that one tries to apply for a
