There is nothing coherent about you.
You are nothing more than what my senses make available to me, and believe it or not, senses are not reliable.
What is a person? There are senses (touch, sight, taste, smell, etc.), there are emotions, and there are memories. There is nothing that I can be certain about, nothing.
Science at the level of the brain suggests that happiness is manufactured in the brain. There is a chemical called brain seratonnin that is responsible for happiness, or the lack of it could be called clinical depression. Things like sunlight, exercise, and certain foods help with production.
Eyewitness accounts are extremely fragile in courtrooms for good reason, because all memories are distorted. You take images from various regions of the brains, and you through cognitive processes force those images together. Think of those images as various shards of class; there are going to be cracks and spaces between them, and the brain fills them in with a variety of things.
Books have published from various academic departments to trouble our easy certainties.
Ideas make their way through the academic arena. This is when the contest of peer review begins; those ideas are harshly criticized, humiliated, strangled, and well, the good ones might stand for a couple years, a couple decades, or a couple centuries. The bad ones will show up in a science journal as a mangled corpse, and consequently, swept from the floor.
This is the best man can do. Ask a scientist.
"...there is not a single law of nature which we know to be valid; the laws of nature are hypotheses which we assert tentatively." Hans Hahn
And how does this relate to his question? It seems you're rambling about nothing in particular.
