This idea is actually about 2,000 years old, but in our own time, some evolutionary psychologists have suggested that these six emotions -- happiness, sadness, fear, disgust, anger, surprise -- are expressed by everyone across the globe in exactly the same way, and therefore represent the building blocks of our entire emotional lives.
Esta idea data de hai 2000 anos mais, nos nosos días, algúns psicólogos evolucionistas  suxiren que estas seis emocións --ledicia, tristura, medo, noxo, ira e sorpresa-- son expresadas por todo o mundo  exactamente do mesmo xeito e, xa que logo, constitúen os piares de toda a nosa vida emocional.
