I read the following phrase today (will not state where as I do not want to cloud the issue)
Phrase: Atheism is the philosophy of death.
I guess the cat's out of the bag. I might as well confess all at this point - there's no use in continuing the lies.
Yes, we atheists follow a philosophy of death. We believe that death is the end of your existence, forever. This being the case, you should try to live every day to the fullest and try to be "in the present" - to experience and enjoy life, day-to-day.
Also, since this is your one shot, make the most of it. Since we don't believe in a magic afterlife paradise, we don't feel you should give in to circumstances and live out the remainder of your life in misery, because there is no big relief or reward at the end. If you want to make life better for you and yours, then get up off your butt and do something about it. If something in life is causing you misery, then change it.
Death is waiting for all of us, and you only get one life, so make sure that you make it count. This is our macabre philosophy of death.
