People generally quarrel because they cannot argue.

This seems to be true in many cases. Arguing for me is an art which leads to stating your point clearly when they contradict with the other. I believe that a quarrel only starts when one is not able to explain to the other what he really wants or when one is not able to understand the true idea of the argument.

Well quarrels are generally the bad side of an argument. One knows that he has no chance of winning/ having a argument so he starts fighting. It is human nature to throw stone for a stone [I also remember a story involving monkeys and a cap seller.]

But what the point in fighting when the outcome always turns out to be worst than before? Why don’t we learn the art of having a healthy argument?

Heart is just a Pump

I don't understand why we put so much emphasis on the Human Heart when it comes to emotions. Since ages the poetic heart has been given importance when it is nothing but a pump. 

As far as I know all our emotions arise from our brain. It is the brain which is the supreme commander which tells which part to function in which way.

Then let us consider a case of a very special person, someone you like very much but are scared to talk with. But when that person comes in front of us then, why does our heart beat rise? Why do we forget half of the things we were going to say? Why do we go about being happy or sad according to that person’s responses? There is a feeling of heaviness around your heart when you are sad. There is a feeling of extreme joy when you achieve what you want.

Everything arises from our brain. How we react to every situation is what we perceive of the world around us. Think about it, why we fall in love with only that special person. Is it because your heart says so? NAAH!!! It is only because your brain has selected that person to be special to you.

Many times we say I am stuck between my heart and my mind while making a decision. Think again you are only stuck between your analytical self and emotional self. Human heart has only one function i.e. pump blood. Emotions are all the state of mind and perhaps these emotions are the ones that make human being the most dominated species on this planet.
