Ten Leaky Buckets correct answer: presenting a series of severally unsound arguments as if their mere conjunction might render them collectively valid: something that needs to be distinguished carefully from the accumulation of evidence, where every item possesses some weight in its own right. Argument from Nature correct answer: The argument from Nature Stated baldly the argument from Nature boils down to the assertion: this is not natural, therefore this is morally wrong. Playing God c...
