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.
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.
Nevertheless if any skillful Servant of Nature shall bring force to bear on matter, and shall vex it and drive it to extremities as if with the purpose of reducing it to nothing, then will matter (since annihilation or true destruction is not possible except by the omnipotence of God) finding itself in these straits, turn and transform itself into strange shapes, passing from one change to another till it has gone through the whole circle and finished the period.
Society is an organism which obeys the immutable law of progress; and change, judicious and cautious change, is necessary for the well being, and indeed the preservation of the social system.
