Animal experiments became an important method of science in the 1900s, marking the birth of experimental sciences. There were, however, guidelines that existed which restricted the conditions of experimentation. These early rules protected the animals. However, from the animals' View point, they would probably not agree considering the unwanted pain they felt, followed by their death. This ethical dilemma can be split into three issues; whether animals have the ability to rationalise, whether they feel pain, or whether these experiments really aim to explore new information. Bernard Rollin, an American philosopher, argues that comparing all differences between humans and animals when discussing this moral issue is ridiculous. He says it is comparable to a person with a full head of hair excluding all bald men from his moral deliberations as they are bald. The main point is whether these differences are moral in nature and, if so, which differences between humans and non-humans are significant?
