There certainly are dangers in science. Many men are all too willing to throw ethics 'under the bus' in order to get a bit of fame or money. The dangers seem particularly relevant in medicine where one is playing around with things far beyond one's understanding.

Look at where genetically modified organisms has taken us. Someone dreams up the idea of having the government grant patent rights to scientists and now there are few foods which are not the product of some mad scientist. Here in the USA, the government is fighting against the very reasonable need to require manufactures to state clearly what has been modified. What are they afraid of?
