What is emotion?

[The Feral Underclass]

Can anyone answer this question?

As far as I know, an emotion is an electrochemical response to external situations or internal thoughts.
For example, When I see a capitalist lose all his stock, that induces a state of mind called happiness in me.
And when I think of the antics of big oil companies, the state of mind induced is anger.

Hormones can also get involved, altering your responses to situations, making you overreact to situations.

If you mean in a philosophical sense, then I have no clue.

But I have noticed one thing, is that there seems to be a bridge between sensations and emotions in the orgasm: You feel it in your head as well as your body.

Emotions are sensations experienced in the head.

The sound that red makes is a funny taste.

If emotions are these chemical responses in the brain, how does your brain know to respond in such a way?

I'm just guessing here, but I reckon it's a combination of genetics and environmental conditioning, leaning more towards environment.
You have the capacity to be angry, and things that make you angry are at first things you can instantly see as detrimental and irritating.
As you get older you can make more tenuous connections, ie the activity of oil companies is harmful to the environment, therefore harmful to you, and their actions are deliberate, therefore you feel frustrated, as well as harbouring resentment against such organisations and people.

Similar things with fear happen, except the fact you see yourself as powerless make your body go into 'run mode' rather than 'fight mode'.

Happiness is pleasure assocation, you feel happy when things are going in a way percieved as benficial to you. How exactly benefits are defined is by your environment. (Upbringing influencing ideologies: A rich kid is more likely to be capitalist, as he has benefitted from the system, whereas poor kids are more likely to have a progressive atittude) Note that I am not allowing for the influences of propoganda.

Sadness is when the negativity that affects you poses no immediate danger, there is no way you can see of dealing with it, and you harbour no animosity.

I think.
