Perhaps measuring animal intelligence by comparing it to human intelligence isn't the best litmus test.
He was a friend to man, and lived in a house by the side of the road. HOMER There are hermit souls that live withdrawnIn the peace of their self-content;There are souls, like stars, that dwell apart,In a fellowless firmament;There are pioneer souls that blaze their pathsWhere highways never ran;But let me live by the side of the roadAnd be a friend to man. Let me live in a house by the side of the road,Where the race of men go byThe men who are good and the men who are bad,As good and as bad as I. I would not sit in the scorners seat,Or hurl the cynics ban;Let me live in a house by the side of the roadAnd be a friend to man. I see from my house by the side of the road,By the side of the highway of life,The men who press with the ardor of hope,The men who are faint with the strife. But I turn not away from their smiles nor their tearsBoth parts of an infinite plan;Let me live in my house by the side of the roadAnd be a friend to man. I know there are brook-gladdened meadows aheadAnd mountains of wearisome height;That the road passes on through the long afternoonAnd stretches away to the night. But still I rejoice when the travellers rejoice,And weep with the strangers that moan. Nor live in my house by the side of the roadLike a man who dwells alone. Let me live in my house by the side of the roadWhere the race of men go byThey are good, they are bad, they are weak, they are strong,Wise, foolish so am I. Then why should I sit in the scorners seatOr hurl the cynics ban?Let me live in my house by the side of the roadAnd be a friend to man.
Quotation... A writer expresses himself in words that have been used before because they give his meaning better than he can give it himself, or because they are beautiful or witty, or because he expects them to touch a cord of association in his reader, or because he wishes to show that he is learned and well read. Quotations due to the last motive are invariably ill-advised; the discerning reader detects it and is contemptuous; the undiscerning is perhaps impressed, but even then is at the same time repelled, pretentious quotations being the surest road to tedium.
