I think before you can determine what is alive/conscious in external objects, you must first define what makes you "alive". Imagine having your
entire memory erased and being sent to a deserted, earth-like planet. No knowledge of language, communication, or prior conditioning, and the only
thing that you have at your disposal are your primitive instincts such as pain/pleasure and flight/fight responses. You would live amongst the trees,
grass, and rocks and be at one with everything, watching a trees leaves blow in the wind for hours without ever getting bored. The trees bear the
fruit that make your unpleasant stomach settle and the rocks outline the stream that quenches your thirst.
For years this goes on until one day you come across a pale hairy figure. It moves like you, it has the same arms as you, and can make the same
noises. And then all of a sudden the creature points at you and then himself and says, "We alive". Then he points at the trees and ground that have
been the bane of your entire existence until this point and he grunts, "They not alive".
The word "life" is just a sound that emulates a certain grouping of things. All language does is separate "yourself" from "them". The entire
time you are talking to someone all your doing is classifying if they are worthy of being befriended and trusted or not. If they will be more of a
pleasure instead of a pain.
Your next door neighbor exists just the same as any tree or rock. They could be a figment of your imagination for all you know...there is no way to
set way to classify what's alive and what isn't. The only thing we can do obey society and trust the pale, hairy figure that looks like us because
they have the most potential to harm us, much like they have the greatest potential to cause us pleasure through sex. Relationships are just
constructs of conditioning...in theory I could love a rock just as much as my mother if I was raised to believe that.
And then your going to have another human come up to you and tell you, "Life is classified as an object that reproduces, maintains homeostasis,
adapts to environment, whatever the other 2 are, blah, blah" But then they are going to say that all living things are composed of cells:
"But what's a cell?"
A collection of atoms.
"But aren't rocks a collection of atoms as well?"
Yes, but they don't function the same way
"Well plant cells don't function the same way as animal cells, does that mean they aren't alive?"
Well no.
"And a dog doesn't appear to be similar to myself, so does that make him less alive than you?"
....No
Sorry about all that writing. But all I'm trying to get across is the point that humans tend to devalue something that isn't similar to us. We write
biased laws in order to protect the wealthy and create a morale code that everyone is supposed to live by. But the sad truth is I have no idea what
you are or what this thing in front of me is, or how it works. I just assume that I understand it and that it's correct because that's what I've
been conditioned to believe. We ask what the "meaning of life" is but we have no idea what life even is, we just assume we have experienced all
there is to experience already. Sorry, I'm going to quit rambling...I don't want to get all into the self-refuting fallacies of these seemingly
impossible questions.
Cheers
