Taoism and Existentialism

Taoism and Existentialism are very different philosophies that spawn ironically similar attitudes. As I an example, I will use the Stranger. In the Stranger, Meursault exhibits an equanimity to which there is no equal. Nearly nothing really phases him, other than being physically uncomfortable, and a lot of things fascinate him. He likes to sleep and pass his time relaxing. Nothing gets him down. Taoism preaches a great equanimity as well. It seems to support inquisitive but gentle minds, and revels in relaxation and satisfaction. It is ironic to me, that two philosophies founded on very different ideas at very different times, have created such similar attitudes towards life. A true existentialist has great equanimity because he feels that life is absurd, and there is nothing after it. Life has no meaning, emotion has no meaning, and morals have no meaning, so why let the little things get you down, or become overly emotional about day to day life? In contrast, a follower of the Tao does his best to manifest the Tao through equanimity because peace and harmony are the way of the world. He does not become upset because gentle and steadfast behavior beget steadfast and gentle results. He relaxes to enjoy the day, he is satisfied because life is full of satisfaction and happiness, if you only stop to enjoy it. Completely different motives spawn incredibly similar attitudes. The attitudes are not the same, there are differences. An existentialist has no problem with immorality or greed, while a Taoist does. The only way you might confuse the two really, is if you only examined their everyday habits and demeanors. So really, in either case, do the ends justify the means?
