There ’s no consensus on the interrogation of what makes us special , or whether we even are . The biggest full point of contestation is whether our cognitive abilities differ from those of other animate being " in kind , " or merely in degree . Are we in a class by ourselves or just the smart ones in our class ?
Charles Darwin supported the latter hypothesis . He believed we are similar to animals , and merely incrementally more thinking as a solvent of our high evolution . But agree to Marc Hauser , manager of the cognitive evolution lab at Harvard University , in a recent article inScientific American , " jump on evidence indicates that , in contrast to Darwin ’s theory of a persistence of nous between humans and other metal money , a unplumbed gap separates our mind from the animal sort . "
Hauser and his colleagues have identify four ability of the human mind that they believe to be the essence of our " humaniqueness " mental trait and ability that describe us from our fellow Earthlings . They are : generative computation , promiscuous combination of estimation , the use of mental symbolic representation , and nonfigurative thought . [ Read : Top 10 Mysteries of the Mind ]
1 . Generative figuring
Humans can bring forth a practically unbounded mixture of discussion and concepts . We do so through two mood of surgery recursive and combinatorial . The recursive operation allow us to apply a learned dominion to create new expressions . In combinatorial functioning , we mix unlike learned elements to make a new construct .
2 . Promiscuous combination of thought
" Promiscuous combining of mind , " Hauser explained , " allows the mingling of different domains of knowledge such as artistic production , sexual urge , blank space , causality and friendship thereby generating raw laws , societal relationships and technologies . "
3 . Mental symbols
Mental symbols are our way of encoding sensorial experience . They form the basis of our complex systems of language and communication . We may take to keep our mental symbols to ourselves , or represent them to others using words or pictures .
4 . Abstract remember
nonobjective thought is the thoughtfulness of thing beyond what we can sense .
" This is not to say that our mental mental faculty sprang fully formed out of nowhere , " Hauser wrote . " researcher have found some of the construction blocks of human cognition in other species . But these building blocks make up only the cementum metrical unit mark of the skyscraper that is the human thinker . The evolutionary origins of our cognitive abilities thus persist rather hazy . clearness is issue from fresh insights and experimental technologies , however . "
