    The idea of progress started to flower in the 17th century． At that time， many wise thinkers believed that man liberated（解放） by reason would rise to greater heights of achievement． The many expressions of human nature would be the engines of progress： language， business， science， and moral sensibility （道德感）． Unfortunately， most of those engines have failed to bring the desired human progress．

The modern age has belonged to material progress and its main source has been science． Science gives people huge power to change the world． But can people be trusted to use it always for good？ Think of biotechnology and information technology． And it is not just that scientific progress does not deliver the emotional good． People also fear that mankind is failing to manage science properly． The forests are disappearing； the ice is melting； privacy is leaking； life is becoming a depressing march in an ugly world．

The point is not that science is harmful， but that scientific progress needs to be mapped tidily onto human progress． That relies on moral sensibility in its widest sense． This liberal force offers hope for a better future． The very idea of moral sensibility probably sounds out﹣of﹣date． Bur researchers find that people desire a sense of moral purpose which would give life dignity （尊严）． People want to determine how the world works， not always to be determined by it． Moral sensibility is why people will suffer from their beliefs， and why acts of noble self﹣sacrifice are so powerful．

It is admitted that our moral ideals will never be realized completely． But sometimes， however imperfectly， we can make progress． Human dignity requires the love of ideals for their own sake， but nothing requires that the love be returned．

Human progress is neither guaranteed nor hopeless． Instead， it is up to us．
