If the same cause has the same effect, what's the point in even trying? Everything that is happening now has already happened the same way an infinite number of times before, and will happen an infinite number of times again. If an instigating factor will have the same effect everytime it happens, aren't we all reliving our own histories? I am a big believer in the perpetual big bang - big crunch - big bang theorum. And if the big bang is the event that sets all events in motion, then surely if it happens again, the universe will repeat itself in the exact same way all over again. How many times would I have battled depression in the past? And how many more times will it repeat itself? Infinitely! Thus, I am an infinite failure. I have no free will, because I am simply repeating every choice that I have already made in the past. My life is a predetermined black hole of loneliness and despair, and if this has caused me to kill myself in a previous itteration of the universe, how can I change that? My intelligence is my curse; it leads me to conclusions of perpetual cycles of a depressing life, and seeing as all that will happen, has already happened, I am depressed to know that my thoughts and my actions are just recycling of cosmic energy. These days I do not see the point in trying if I cannot affect my life, as it has already been set in motion by the same cause that created the universe we know today.
