In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
Being concerned about other people is especially relevant in today's world. If we consider the complex inter-connected ness of our modern lives, how we depend on others and others depend on us, our outlook will change. We’ll begin to see 'others' not as somehow distant from us, but as people we are in touch with, people close to us; we will no longer feel indifferent to them.
Those persons are happiest in this restless and mutable world who are in love with change, who delight in what is new simply because it differs from what is old; who rejoice in every innovation, and find a strange alert pleasure in all that is, and that has never been before.
All things that we ordained festival
Turn from their office to black funeral--
Our instruments to melancholy bells,
Our wedding cheer to a sad burial feast;
Our solemn hymns to sullen dirges change;
Our bridal flowers serve for a buried corse;
And all things change them to the contrary.
When you get free from certain fixed concepts of the way the world is, you find it is far more subtle, and far more miraculous, than you thought it was.
