"Purity of Heart is to will one thing." (Søren Kierkegaard)
True, false, good, bad, useful, not so useful, etc.? Discuss.
My thoughts:
The aphorism is also the title of the work from which it's taken; that essay is about single-mindedness and total devotion to "the good" (which to Kierkegaard meant God), as opposed to attempting to "serve two masters."
Interesting, but there are really two ways to approach it, because we all have to eat.
One of those ways is to take a vow of poverty and intentionally adopt an ascetic, devotional lifestyle even at the price of possible starvation, etc.
The other is to be born into, and for life enjoy, a certain degree of affluence that leaves one free to express and act on such devotion without worry as to where the next meal will come from.
Kierkegard was in the latter category, and while I find his writings quite interesting in general, I perceive a bit of "let them eat cake" naïveté in this particular aphorism.
