what are we doing here?

some kind of caffeine fueled existential crisis might or might not have led me to this website and this quote below:

Leading neuroscientist Susan Greenfield believes humans are intrinsically individual.
Chimps can use rudimentary tools, eat, sleep and copulate - but they don't wear jewellery or any other kind of adornments. Why? Because humans can see a metaphor - view things in terms of something else - while animals cannot.That leads to the creation of status symbols like crowns and jewels, which are not in an animal's nature.

(emphasis my own) 

we enjoy metaphor, hence our fascination with stories and poems but i wasn't exactly thinking about metaphor; i was wondering about absurdity in our lives. the merriam-webster dictionary defines absurd as 

"1: ridiculously unreasonable, unsound, or incongruous absurd

argument>"

it defines incongrous as:

: lacking congruity: as

a : not harmonious : incompatible <incongruous colors>

b : not conforming : disagreeing incongruous

with principle>

c : inconsistent within itself incongruous story>

d : lacking propriety : unsuitable <incongruous manners>

(emphasis, again, my own)  

 

hence i was thinking about the inconsistency within our lives - and i was wondering which of the other words would be more suitable: disharmony (a) or unsuitability (d)? whether the two of those words explain the extremes of our human behaviour? if the first explains cruelty and selfishness; and the second explains everything funny? 

 

hence, our human experience is basically characterised by not only our ability to see metaphor, ie, view things in terms of something else; but also do that with inconsistency within itself... and suddenly the human experience seems a whole less desirable than it did before. but none of the words above explain kindness - the most uniform of all our experiences and i think there might be some more words i might need to dig for, and something still worth being a human for.
