"My life is full of meaning, purpose, hope..."<quoted text>
It's really a shame what they did to you. My life is full of meaning, purpose, hope, enthusiasm and vitality. You sound dead already.
BTW, you're utilizing a fallacy that I can't find a name for, so I call it the fallacy of scale. A life has meaning at a certain scale of space and time. At too small a size or for too short a time, life as no meaning. For particles decaying in nanoseconds, most of the qualities of our experience don't exist. There is no wetness there, and no glare. There is no humor and no fear.
Likewise, from too far away, or when looking at too large a volume of space, once again, there is no sign of life at all. And over deep time, no life time matters at all.
That's your argument - that in the grand scheme of things, considering the whole universe over trillions of years, my life doesn't matter. I agree.
But that's a fallacy to say that what is true at an extreme scale is true at all scales. We don't exist at the level of the grand scheme of things - just in a few square miles of the surface of one small planet for a few decades.
Why should my influence be expected to extend so far into time and space - or its failure to do so - constitute the basis of an argument against it having meaning? It shouldn't and it doesn't.
Notice that you're using the cosmological scale to negate the meaning in a life. More commonly, it's done at the microscopic level: "If we're nothing but chemicals,our lives cannot have meaning." It's as fallacious as calling Shakespeare meaningless if it is just so many letters, spaces, and punctuation marks. Yes, at that scale, Shakespeare is also pretty meaningless.
would you mind clarifying that 'hope' piece please?
how could anyone who believes in & promotes eternal extinction POSSIBLY have hope???
you're (relatively) vain existence is fix'n to come to screeching hault in a (relatively) short period of time!
