Sometimes we get lost in the philosophy, and the arguments, and the justifications, and we lose sight of the fact all of these things have to be filtered through our own personal experience. Yes, we all share a great deal of commonality with every other person on the planet, but none of those other people will ever be *you*. It's all well and good to understand the arguments against God's existence, but what do they mean to you, personally, uniquely? Alone in your mind, how do you deal with the fact that we are accountable to nobody but ourselves and those we share this planet with? I will readily admit that such questions can be overwhelming, at times. Questions of meaning and purpose aren't easy, and shedding the false comforts of religion offers no guarantee that things will be any easier.
The point that I liked best in Savulescu's essay is a simple one, though: Life can be a bitch, and you will certainly not make it out alive. You may live to be 100, surrounded by material wealth and persons that you love. Or, you may get hit by a bus crossing the street this afternoon. Or, you may contract a debilitating disease that promises a slow and agonizing death. Such is the way of life in a cold, random, uncaring universe. There are no guarantees, so make the most of this life while you have the opportunity to do so. Seize the time you have, because you have a finite amount of it.
