From a purely biological viewpoint, there is little difference between the citizens of a republic and the subjects of a king. And what about ‘happiness’? So far biological research has failed to come up with a clear definition of happiness or a way to measure it objectively. Most biological studies acknowledge only the existence of pleasure, which is more easily defined and measured. So ‘life, liberty, and the pursuit of happiness’ should be translated into ‘life and the pursuit of pleasure’.
