If you hired me to build you a house after I assured you I was the best house builder around, and after investing much of your hard-earned money and a lot of your time, the house I built fell in upon itself, would you hire me to build you another house? Even if it wasn't your house I did a shoddy job on, would any of you hire me to build your home with my track record of such a horrible mistake, even if it was only one horribly-built fiasco I was responsible for? I would be surprised if you did.
Try as one can, there is still no definitive scientific theory of "love" or "loyalty." What you folks are pointing out is not proving "love," but other things associated with what we call "love." If there is such a scientifically proven thing as "love," then what is its agreed upon scientific definition? Who defined the "theory of love" or discovered the "theoretic model of loyalty"? No one. You won't find a Newton or Einstein responsible for these discoveries. These aren't scientific notions, not in themselves.
I do not mean to insult anyone here who have different views than mine. You are no less a person because you are atheist or agnostic or theist. Forgive me where my words seem disrespectful. But at times we struggle to have or find answers when there are none. This is partially due to a characteristic some of us may have in common.
Some of us want very much to be right or have the true view of life and the world around us. Having been in the Watchtower form of religion that abused us with such a facade of truth, it is no wonder we strive for accuracy and realistic logic-based understandings instead of silly notions.
Yet for some of us (obviously not all) we have not moved past the view that we need to be right and that we need to have the truth once again. We had this view as Witnesses, and maybe for some, like me, it has been a character trait not easily dismissed or even recognizable in ourselves. Our desire to be in the "right" religion and have "the truth" is not one universal in the world of religion, though the JWs often left us with the impression that it is. It isn't as widely shared as some of us may have been taught.
Upon leaving the Watchtower we who have this trait may not have let it go. Again we think our current view, be it a new religion, atheism, or agnosticism is the "right" one, and we debate with others who do not share our "truth," even acting as hateful and disrespectful of others with views that conflict with ours similar in fashion to the Witnesses regarding other religions. We might close ourselves off to reasoning others may offer for their convictions, insult them for having these views different from ours, and then use our views as a panacea to supply us with "all the answers we need" in this world.
But it may be that we are just as scared to be without thinking we are "right" or have "the truth," since having "answers" gives us a feeling of control. No convictions, philosophies, or even science can give us all the answers. Just like there is not a religious answer to everything, there is not a scientific answer to everything either. We can't keep trading one "panacea" for another, as there is likely no one "right" way or "truth." That is just another lie of the Watchtower. We can't have the answers to everything. We can't find something that will make us "right" with the correct answers about everything, science included.
And, if we are ex-JWs, we are the last people who should be thinking or declaring we have the right answers, debating with others to prove them wrong and defend our new-found convictions as right. Like the house builder who made a horrible house, our track record with finding the "truth" and thinking we have all the answers is not very good. We should learn that we are not suddenly experts at knowing the right way to go in life just becuase we left one path that was clearly wrong. It doesn't work that way.
Science doesn't always have the answer. You can't always be sure you are right at this point in your life just because you're not a JW anymore and have found atheism or a new relgion or whatever. There may be no definitive right way. But that is no reason to be frightened nor an excuse to think we can't be wrong again where we now stand. We need to be humble because, in all truth, no one in their right mind is going to "hire us to build them a house" with our track record.
