"There is something more truthful to the feeling of love than all the rationality. Love makes decisions for us far more often than logic. It has a potent effect on most people."

This is what logic refers to as a Post Hoc fallacy, or post hoc ergo propter hoc. It basically means that because B comes after A or is somehow associated with A, A is still not necessarily the cause of B. To say that it is without evidence an assumption and is logically unsound reasoning. Events that are unrelated functionally can still occur together within a single framework.

A correct statement would be: "We make decisions based on our feelings of love." But love does not make decisions. Love is an emotion originating in limbic region of the brain, and the limbic region has no capacity for thought or decision making.

Here's what has been proven to happen in the brain through current mapping technology:
  1. A thought evolves in the frontal lobe.
  2. A reaction to that thought is cued when a signal is sent to the limbic region.
  3. The limbic region transmits an impulse to the body and the frontal lobe (feelings of love).
  4. The frontal lobe modifies behavior and memory as a reaction to emotional impulses emerging from the limbic region.
Depending on how strong a grip on reason the individual has, the reaction of the thinking brain in the frontal lobe to the love impulse will either be rational, irrational, or somewhere in between.

Logic and reason is the only way the human brain has to make a decision. Barring logic, a human being relies on instinct and intuition instead. Instinct and intuition aren't thinking, they are the default choices left to the brain when the brain fails to use reason. Such as reflex moves when your skin touched by the fire.

"Feelings/emotions impact everything, that’s why we have biases."

There is no such thing as decision-making without thinking. You can make a choice without thinking by simply following your instinct. But you aren't making a decision. You are just allowing an action to occur. Hunger and sexual desire are instinct, but to look for food and sex, the actions come only from "the thinking part" or the "instinct part" of the brain. There are some people who think to get a job, and others think to rob and steal. There are some people who think to masturbate, and others think to rape.

Yes. Frontal lobe can modifies behavior and memory as a reaction to emotional impulses emerging from the limbic region. We have biases from emotion and feelings, but at the end of the process, our frontal lobe (thought / logic / thinking) is the only one who come up with actions-making.

"Haven't you ever made a decision and been surprised that you made that decision? And how is instinct different than feeling?"

We've made decisions that in retrospect were the wrong ones. But we've never made a decision without some form of thought first. Decisions are always the product of thought. When we made bad decisions, at current moment, our logic / thought is not that good. Period.

Instincts are different from emotions and feelings, in that: 1) They come from a different part of the brain, and 2) Instincts can cause actions, emotions and feelings cannot cause actions on their own. When you are angry and kill someone, the action did not comes from the part of the brain that regulate emotions / feelings, but comes from the part that regulate logic/ thought. When you kill someone, it is only possible for instinctive mechanism (survival / self defense) or thinking mechanism (logic), it is never about emotions.

I repeat, emotions can influence the thought, but emotions can not cause actions. “Men often use the logic portion larger than the feeling” is a tricky statement, because all human, men or women, with healthy brains, always use the logic portion at the end of their actions. It doesn't matter how great you use a portion of feelings, all human’s actions depend on frontal lobe; the quality of your thoughts.

"Emotions cannot cause actions on their own? So, where does self-sacrifice come in then?"

Self-sacrifice is a part of the survival instinct. That is a function of the thinking brain, not the emotional brain. The problem is, we have a very long history of emotion being romanticized as some form of thought in culture and literature. And although science has already proved this notion to be false, it is a difficult one to let go on when we have basically been programmed by society to think in these terms.

"You have to think with your heart, and not your head." Sound familiar? Neither thought nor emotion comes from the heart muscle.

I’m not discarding emotion. I am putting emotion in its place by defining it correctly. For the average person, it doesn't matter. You can drive a car without knowing how the engine works. However, one day you may need to know how the engine works if you want to fix your car. Logic is mechanic in a way. It is necessary to know how things really work, not how we think or hope they work.

Neurologically speaking, there is no time when a person has an emotional impulse that is not triggered by activity in the frontal lobe (the thinking brain). That's how our brains work. Even when the cause of emotion comes from external stimuli, that stimuli always passes through the thinking brain first. If a person is having emotional impulses without a cause from the thinking brain, then they have something organically wrong with their brain and are probably in need of treatment of some kind. Because its not normal that a human brain would be doing that.

Recently, scientists (Joseph Parvizi) have used electromagnetic impulses to artificially trigger emotion in the brain that would otherwise require a thought trigger. It's yielded some interesting results.

Artificially triggering neurons in the brain does not reproduce what naturally occurs in the brain. It’s a bypass procedure. You can’t conclude that anything that occurs as a result is normal brain function.

Example: Mice can have their hunger impulse triggered artificially even though they just ate and still full. That does not occur normally, so we cannot conclude that hunger occurs in mice even when they aren't hungry.

Divine love is worth cultivating. Unfortunately the only thing here in this world that even comes close, is the love of a mother for her child. All other love is driven by greater or lesser degrees of ulterior motive / passion / desire / lust.

Sex without love is just a mechanical process of release of energy, a temporary stress-buster. Sex with love is a spiritual expression of two bodies uniting together to realize godliness. However, attachment to such kind of love may bring obstacles as the pressure of commitment will put aside freedom to live independently.

How fast do you fall in love? Depends on the amount of oxytocin you have stored and its release rate. Depends on how well my neural connections in my brain is firing and if there are connections made and being made through shared interests, attractions, and similarities.

But, then again. The number of girls who cried a lot when I was in high school compared to the number of boys is enough scientific proof for me that "men use large portion of logic and women use large portion of feelings."
