From G. K. Chesterton’s essay “The Ethics of Elfland” http://www.chosunjournal.com/ethics.html (please read as much of this astounding essay as you can, but at least this):
I wonder how people react to this approach towards developing a philosophy of life. Perhaps some do not identify with the five “feelings” Chesterton describes here. Perhaps some identify with the feelings but hesitate to take them as personal beliefs, as the basis for a personal philosophy on life.
I hesitate myself. I say “so what if it seems like the universe is a work of art, designed by a loving creator? It could still be the case that the universe simply is without explanation, regardless of your feelings. So don’t trust your feelings because you might be wrong, and that would be terrible. Best to stick only with what you know.”
The problem is, we don’t really know anything of significance. All I can say that I know right now is that I’m perceiving many things and thinking about these many things in terms of many categories (color, shape, size, letter, language, etc.) Do I really know if there is a computer screen in front of me? No, it could be an illusion, and no amount of science can eliminate that doubt. All I know about are perceptions. Even my idea that there is a sequence of perceptions ordered by something called “time” could be incorrect, because this idea relies on a perception which I call memory, and could be just as unreliable as the perception of a computer screen in front of me. My only undeniable, undoubtable knowledge is that of my current perceptions.
Given this immense poverty of knowledge, how can I decide how I will live, or what I will choose to do? The answer begins to emerge even from how I have asked the question: I have assumed that there is such a thing as “I” which can “choose” how to “act”, whatever all that means. I’ve assumed these things because my heart tells me to do so. I have no rational defense for these assumptions; it’s purely emotional and pre-rational. Someone could argue to me that I’d be better off not making those assumptions and I’d have no answer, except “listen to your heart; that’s what I do” (to quote the wise Napoleon Dynamite).
To understand why the heart is so important, ask yourself the following question: will you kill yourself right now? If so or if not, why? I think that there is no rational way to defend the decision either way. There are infinitely many and varied possibilities that killing yourself might bring – some you might consider desirable, some undesirable, some neutral. Perhaps by killing yourself you go to eternal torment, or perhaps to heaven. Perhaps by failing to kill yourself right now you eventually go to heaven, or perhaps to eternal torment. Perhaps it doesn’t matter in either case. Perhaps (after Nietzsche) you will live out your decision infinitely many times after this, or perhaps you will live out whatever decision you did not make infinitely times after this. And so on and so on ad nauseam. Clearly in the rational analysis of outcomes and pros vs. cons, there is an unbreakable tie here. But not in real life. In real life you choose one way or the other, and not based on reason but based on emotion. You follow your heart with ABSOLUTELY NO REASON OR JUSTIFICATION WHATSOEVER.
Now if such a momentous decision as suicide is decided without any reason or justification, can any of the mundane actions of our lives be considered truly rational or justified? Aren’t we all just following our emotions, our hearts, from moment to moment, using reason only as a handmaiden to whatever the heart seeks? I would say yes, everything we do (even using reason) we do because we’re following our emotions (which we DO know because we perceive/feel them, and perceptions/feelings are the little that we do know in life).
So if all I’m doing is following my heart and my emotions from moment to moment, how do I decide when I have conflicting emotions about something? For example, killing someone, or following a certain religion, or eating something fattening. Do I just try to feel out which emotion is the deepest, strongest, most essential to who I am? What am I doing?
And if you share Chesterton’s feelings above, is that enough of a basis for following those feelings by believing in a personal God or some such thing?
