Intelligent design and Natural Selection
I understand that darwin's theory of evolution must be true.
I also developed some insights by just thinking about evolution before.
But I feel that beleiving in it strongly makes us too strongly scientific, and less religious/spiiritual. And that this can have negative consequences, on the well being of our emotional lives and institutions.
I think it is good to give a mention to Intelligent Design in biology textbooks, saying that some people do beleive in such a theory.
This may leave some more place in their hearts to follow religion later in their lives.
