All of these ideas just came to my thoughtful mind that made me come to think of it. These could trigger some arguments. I may add further concepts that I thought of and append them to this archive. Meron pa kong nakalimutang iba.

1) If every human has a soul, then there are approximately 6 billion souls in this world plus the souls of the departed that are still wandering with us.

2) The number of souls is equal to the number of humans that lived throughout history, which is the summation of the population of human beings in a given time, say second, minus the intersection of the elements of the population in the two given seconds, multiplied by the number of seconds of the whole human history.

3) We have the belief that souls leave the human body as it dies, then it goes wherever it may want to, or supposed to. So we may deduce that the soul is part of the human body for it is included in the dying stage of a human which is biological, that is according to popular belief. I have the belief that our souls exist in the minds of other people who knows us. For example, if I would die, my soul will exist on your minds only and only in the minds of people who knows me. The people who never knew me thinks that i never existed, therefore my soul never existed for them.

4) If light travels, everything we see is the past. The light that comes from the object that we are looking at will have to travel to reach our eyes, which takes time. We never see the present. Absolute present time does not exist. We know that time is a concept, and every concept exists in our brain, which has lots of processes on its job queue. Processing in the brain takes time, no matter how fast your brain cells act, it will take time. So while thinking of when is the present, the present has just become a part of the past.

5) Abstract objects like concepts are relative. We have different interpretations of concept. Everything is relative.

6) History begins from the most primitive imagination a human can think of relative from today's situation and environment.

5) Measuring the height of civilization depends on its written history. The more its history was written, the more civilized it was. Nobody knows what was happening in the Philippines during the time of Alexander the Great, except for its inhabitants probably, who didn't know how to write then, which is a form of civilization.
