Arun Laskar

A scientific man ought to have no wishes, no affections, - a mere heart of stone. A moral being is one who is capable of reflecting on his past actions and their motives - of approving of some and disapproving of others. In the long history of humankind (and animal kind, too) those who learned to collaborate and improvise most effectively have prevailed. It is not the strongest of the species that survives, nor the most intelligent that survives. It is the one that is the most adaptable to change. --Charles Darwin
