Langer states that the only reason humans have a higher intelligence then animals is that be use symbols to mean multiple things. this ability to imagine the metaphysical and metaphorical meanings of symbols and act on this perceived knowledge is why humans are unrealistic. this article seems to be be focusing heavily on religion as a symbol the article is called "the lord of creation" this could be in reference to God, however i think it is in referring to man's ability to make symbols have multiple and diverse meanings. in the lives of animals religion would be a hindrance to their survival, it doesn't give them an advantage. yet, in human society the spiritual aspect of life is considered one of the most important things to being human. As stated in the article " sheep in the pasture do not seem to fear phantom sheep beyond the fence...birds do not worship a divine thunderbird." i think it can be best described as animals live to fulfill basic needs: food,shelter, and water. whereas humans also do that, but we are dissatisfied by not being able to know everything. a horse might run really fast in a race, and it most likely understands that if it dose what its been trained to do it will get a feed bag. the race horse will not wonder why it runs against other horses nor will it refuse to race because that would mean it doesn't meet a basic need of food.
Humanity might be the only living organism that fears unseen enemies and prays to a deity, yet we are the only ones who take joy in the concepts like beauty, self-actualization, love, and many others. this allows humanity to experience a vast pool of endeavors. Langer also mentions how humans are also the only ones that are cruel for cruelty sake this another alienating factor between humans and animals.
