Peace does not mean an absence of conflicts; differences will always be there. Peace means solving these differences through peaceful means; through dialogue, education, knowledge; and through humane ways.
After Darwin, God's role changes from being the designer of all creatures great and small to being the designer of the laws of nature, from which natural selection can unfold, to being perhaps just the chooser of the laws. By the time God's role has been so diminished, he becomes a bit like a constitutional monarch, presiding ceremonially but not having any more work to do. That's a place for God if it makes people comfortable to keep God as the presider over the universe. I suppose that is satisfying for many.
I think of consciousness as a bottomless lake, whose waters seem transparent, yet into which we can clearly see but a little way.But in this water there are countless objects at different depths; and certain influences will give certain kinds of those objects an upward influence which may be intense enough and continue long enough to bring them into the upper visible layer. After the impulse ceases they commence to sink downwards.
Just as we cannot think of spatial objects at all apart from space, or temporal objects apart from time, so we cannot think of any object apart from the possibility of its connexion with other things.
There are two types of people who will tell you that you cannot make a difference in this world: those who are afraid to try and those who are afraid you will succeed.
