Okay, it's 10:30 PM at night, I should be doing my homework, and yet I am posting here...
I'm not going to read through all four pages, but I do have a few thoughts about life, consciousness, and existence.
How do you define life? How do you define consciousness? How do you define being alive?
To me, the human psyche is merely an unimaginably complex computer program running an infinite loop, until the hardware the program runs on (your body) fails, at which point the program is terminated, and you are dead. This program is able to take in input, such as the image of a tiger; then it gives output, telling you it's dangerous and run for your life. The human consciousness is simply an infinite loop of taking inputs, processing information, producing outputs, then repeat; it's nothing but a program. Death is simply the termination of the program due to hardware failure, so there is no logical place after death. Technically, "you" don't truly exist, because your thoughts are simply the program's inputs, calculations, and outputs. If there is one thing that defines your identity, it is the structure of how information is processed in your program; for each person the processes are different, because each person reacts differently in one situation (e.g. one person might panic when he sees a tiger, while another might stay perfectly calm). Thus, souls don't exist, because software cannot exist without hardware.
And I've often thought about the meaning of life, and the ultimate value behind the existence of consciousness and life forms. I tried, and I couldn't figure it out. So I decided to stop caring and live in ignorance... for now.
