True... and that happiness is typically short lived...
Yes marital happiness is probably fleeting in many. However, I have the same feelings, and the rush of passion as I did as a teenager when my partner walks into the room. I met her in college 41 years ago. We've kept it alive, and even more so in the past 18months. ((Figure me this. I had low testosterone, and when we met back up again, I had it checked. I went from 239 ng/dl Testosterone level (at the HRT level) to well over 600 ng/dl after hooking back up with her (38 years later - we had lost touch). How can a person, or your brain seeing the person have such a dramatic effect. The doctors are stymied - they claim it's not possible.))
Because we don't understand the Brain (the most complex machine in the Universe thus far) doesn't mean it needs to have a supernatural explanation. (See Isaac Asimov's comments on technological 'magic'.)
The first sentence is not clear to me. The double negative may be the issue. Can you clarify?
I did, indeed use a double negative - (editing at 4am). Life has no innate 'purpose', imo. Its function or aspect or outcome is what you make of it. The function of my brain, operating fully, is that +I+ am driven to try to understand my nature, human nature, and to gain knowledge (that's what computational systems using heuristic algorithms do). I can take on a 'purpose' in a sociological sense, but there's no innate 'divine purpose' related to a supernatural cause that can be shown.
Consider Newcomb's paradox on free will. We can not know and have no terms to define things that happen outside our 'system' (the known Universe). Thus we can not know "God". The description of a 9th dimensional being is beyond us. Thanks for the correction.
