I was thinking about this a few days ago :o
hmm.. What do you exactly mean by ghost?
I read meaning of 'Ghost' in my dictionary. It says ghost is: an apparition of a dead
person which is believed to appear to the living, typically as a nebulous image.
And i guess I can add some more to it based on the ghost stories I've heard:
it tends to show a few feelings too, like anger, hatred, compassion, sorrow and sometimes it does some bad or good
things based on those feelings.
an 'apparition'. So it must be a thing that can be 'seen'. So that means, it reflects/refracts/emit light. That should
mean that it certainly has a mass. So if ghosts exist and they can be seen(though it may for a limited time, at a
particular place) it must mean, they have mass, right? It might be possible that they're seen only at some places at
some times, because some physical phenomenon occurs only at that particular time and place.. some what like aurora
borealis. And coincidentally, those phenomenon appear to be of human shape.
Even if we allow this very difficult thing to happen, we can only call them a natural 'phenomenon'. But 'ghosts' also
have other qualities. They sometimes have voices, they can interact with things too, and that too not randomly, but with
a sense of purpose based on their(or their living self's) 'emotions'.
I don't know what 'consciousness' is.. I mean, what separates us from lower life forms? our ability to think? Like,
bacterias and viruses, are they any different that just some chemical reactions? But humans(and even other higher
animals, mammals, birds, etc.) are different, right? So.. Idk, what makes them different. But one thing is for certain,
all those beings who can feel, think, etc.. have a complex structure.. and a very complex organ: The brain! :O (some
people believe that even plants have emotions, and they too feel pain, etc.. But I don't know how they can ;-;)
But Ghosts, aren't so complex, they 'barely exist'. They can only be seen faintly, due to some physical phenomena. I
mean they are just like a big bunch of atomic particles, like dust, rocks, etc. >.<
I don't think they can perform complex operations like 'thinking', having emotions, changing quickly according to the
surroundings(like following someone running away). Even if these particles are possessed by the (inexplicable) things like soul/spirit, the soul won't have a capable
enough medium to enforce those actions, right? I mean, if souls could have controlled other such random relatively less
organised particles, we would have seen many non-living things doing things they can do) WE can move because our brain
orders(sends some signals) to our organs and then the organs act(reactions are caused on receiving those signals) These
things need a trigger signal right? And for that a 'brain' is required..
Tulip said that there have been some evidences of existence of 'ghosts' and their existence was detected by some
scientific instruments based on electromagnetism principles.. well... even if that's true, then doesn't it mean that
those things detected were so lowly that we had to detect them with the help of scientific instruments? Would those
things be able to do things like 'thinking'
It may be possible that those things are harmful to humans, but they don't do it purposefully! If they cause harm, then
it'll be only because of chemical reactions. e.g. if some poisonous gas leaks in the air and people are harmed, it's not
because the gas 'hates' people or is 'sad'. It'll always harm us. So it cannot be called as 'ghost'.
So, I think I don't believe in ghosts...
But Idk what this 'soul' thing is.. so I can believe in zombies xD
I mean, they've got braaaiiiins and other essential body parts, right? What does 'being dead' mean? If we somehow manage
to restore a dead body exactly as it was before(i know it's impossible), will it start thinking and walking? :O If it's
so, then there's no such thing as soul and everything is just chemical reactions >__>
But if it's not so, there might be a few weird things out there. o.O (but not ghosts)
ofc, my post was based on the definition of ghost written in my dictionary. Other kind of ghosts can exist ^^"
And my reasoning can be(probably is) flawed too. I just like to SPAM such discussion
threads once in a while ^^"
and btw, i haven't really read any articles on the internet about this thing, even the one I've linked. So, an in-depth
study can give a better answer.
edit: Whoa! BIG post! :O
