Materialism, part 2

Regarding the passage from Wisdom, below, you don't hear many people say, "Let our might be our law of right, for what is weak proves itself to be useless." But that's materialism's logical conclusion. If it's true that there's no God, and reason is nothing but "a spark kindled by the beating of our hearts", then it isn't true that "all men are created equal, that they are endowed by their Creator with certain unalienable rights". Rights granted you by other humans rather than by God aren't unalienable at all-- they can be taken away for any reason that seems good. And who decides which reasons are good? Whoever has power to do so. "Let our might be our law of right." We see plenty of that in our country: the very old, the severely disabled, the unwanted unborn, Terri Schiavo, anyone diagnosed prenatally with a genetic abnormality, all are in danger of being put to death. Most of these people are killed on the theory that it's a kindness, that their lives are not worth living any more, or won't be worth living. ("What is weak proves itself to be useless.") So materialism leads to humans arrogating to themselves the right to decide which lives are worth living. The issues today are different but the underlying philosophies look the same as they did a few thousand years ago....
