About brains, hearts and gonads

Reading Gene expression of Razib Khan often gives opportunity to think things anew. Here are some new thoughts of mine about religion:

Humans have a brain, humans have a heart and humans have gonads. Scientists often forget that "thing between" - because THIS is a really complicated thing.

I think, it is too often overlooked today, that religion (and philosophical metaphysics of any sort) in former days had mostly to do with that "thing between". Both of the two other organs, people thought in former times, should be ruled by the heart. So - for example - in former days it was not so important for people to believe in a PERSONAL god (because this is mostly a theme of the brain), but it was important for them to have a good heart and to be a good person in everyday life and family life. And they were aware, that being a good person with a good heart HAS (often) very much to do with certain metaphysics. Because metaphysics can give you motivations to behave (very) altruistically.

Today we too often only take our brain, when we try to understand religion and metaphysics. And we forget the function of religions and metaphysics concerning hearts, and that means mostly: concerning feelings of love and hate. I think, this is a main function of deception and self-deception also. And deception and self-deception is not only a thing of individuals but also of communities, societies, even epochs.

If humans have too much (one-sided) gonads-activity, the "things between" will mostly be forgotten. And if humans have too much (one-sided) brain-activity the "things between" also will be forgotten.
