Query: The author was quite biased and didn't think about the issue deeply enough

I read this book when I was trying to make a decision about whether or not to have kids, and it did not help me at all. I found that she did not give very many reasons why one would *want* children. She only gave reasons for why one wouldn't want children. I think it was because she had not reflected on the question enough. Reflecting on this now, I think one great reason is a spiritual one: you want to pass your values down to your children as part of the greater goal of the development of humanity.
