In this paper, authors opine that Islamic economics literature exclusively attributes pure altruism to Muslims. It contrasts homo economicus with homo-Islamicus. Authors try to show through empirical evidence that giving behaviour is not much different among Muslims and non-Muslim in Europe.
The doctors and nurses who have risked their lives to treat patients have defied these explanations and proved that altruism can be genuine. The idea of selfish self-interest needs revision. John Nash gave the idea that everybody does what’s best for him and the group. Referring to humans as a group, Dawkins think that Selfish Gene has no inherent morals and only has survival instincts. Morality is then just an instrument to achieve survival of the fittest.
