Close-minded

The difference between the atheists and the scientists is this: atheists can afford to be dogmatic or close-minded, but scientists cannot; their job or profession forbids them to be so. As scientists they have got some responsibility that the atheists do not have. As scientists they are supposed to provide explanation for all the events, phenomena or effects in nature and therefore they have to keep their mind open to the possibility that they may not always be able to explain everything purely naturally.
