Yes there is. He is just laying the groundwork. As with any book, you will not agree with everything. However, there is no doubting that a woman wants a man to be a balance of alpha and beta. I am the classic Mr. Nice guy. I have learned to become more assertive and take the lead in our home in many areas including sexually. I also think the whole idea of captain and first officer is spot on.
I think there is a lot of real obvious "well duh!" type stuff in many of the often referenced men's self help material.
That does not make it worthless however. I can only speak for myself, but I failed to see the obvious and even more so fail to act on the obvious. Many times I have/had to fix various disfunctions within myself in order to take some pretty obvious actions :scratchhead:
I must also say that it is important to understand the biological/hormonal reason for the concept. Since sex, alpha, and beta create different hormonal response, we need to know how our actions affect this response.
