Sören Kierkegaard:
There is only one end: the genuine Good; and only one means: this, to be willing only to use those means which genuinely are good — but the genuine Good is precisely the end. In time and on earth one distinguishes between the two and considers that the end is more important than the means. One thinks that the end is the main thing and demands of one who is striving that he reach the end. He need not be so particular about the means. Yet this is not so, and to gain an end in this fashion is an unholy act of impatience. In the judgment of eternity the relation between the end and the means is rather the reverse of this. If a man sets himself a goal for his endeavor here in this life, and he fails to reach it, then, in the judgment of eternity, it is quite possible that he may be blameless. Yes, he may even be worthy of praise. He might have been prevented by death, or by an adversity that is beyond his control: in which case he is entirely without blame. He might even have been prevented from reaching the goal just by being unwilling to use any other means than those which the judgment of eternity permits. In which case by his very renunciation of the impatience of passion and the inventions of cleverness, he is even worthy of praise. He is not, therefore, eternally responsible for whether he reaches his goal within this world of time. But without exception, he is eternally responsible for the kind of means he uses. And when he will only use or only uses those means which are genuinely good, then, in the judgment of eternity, he is at the goal.
