man always need a higher ideal to submit his mind and will.some have devoleped their own value system,some people borrow an already existing framework like religion or communism(yes party is more or less like a church).

you have people like gandhi,martin luthur,mother theresa who have so much good to humanity,and they were all religious people.

and one more thing,we always do not think using language,most of the time we think in terms of visuals,and some thoughts are very difficult to translate in to words thats why we have music,and visual art forms like painting,sculptring etc.Language has got its limit.i am not contradicting you ,just adding one more point.
