If you think about what we normally take as giving life a lot of its meaning -- music, humor, eroticism, spirituality, aesthetics, nurturing and caring, gossip, chatting with people -- all of these, very likely, are enabled by a special circuitry that we humans have, but that you could have another intelligent life form that lacks these.
Se pensarmos no que normalmente dá sentido à vida... música, humor, erotismo, espiritualidade, estética, carinho e atenção, fofoca, bate-papos. Tudo isso, provavelmente, faz parte de um circuito que nós humanos temos, mas outras formas de vida inteligente não possuem.
