Why do we always want what we can't have?
I've been wondering this a lot lately. Humans tend to desire things that they weren't intended to have, or simply cannot obtain, for reasons unknown. One of my questions is, why do we want what isn't available to us?
It's seen throughout these forums. People who want <blank> item, even though they know they cant. Very good example is flames. Only a few people have them, and in the Market thread, you can see people desperately bidding away on the few flames that are in existence. I am one of these, I'm not denying it.
However impossible some things seem though, they can be seen as the cause of many improvements (so called) to society. Humans wished to move faster than their legs would carry them, so they used horses, and later cars. Humans wished to travel over water, boats were made. Humans wished to fly, thus planes were created. These are but a few items that have been invented that have contributed to the forward movement of society. Guns, computers, cameras, all of these have been created out of some impossible human dream.
Does this odd desire for the impossible, prove to be vital to our progression as a race? Why does this desire exist in the first place? Discuss
