דֶּ֤רֶךְ הַנֶּ֨שֶׁר ׀ בַּשָּׁמַיִם֮ דֶּ֥רֶךְ נָחָ֗שׁ עֲלֵ֫י צ֥וּר דֶּֽרֶךְ־אֳנִיָּ֥ה בְלֶב־יָ֑ם וְדֶ֖רֶךְ גֶּ֣בֶר בְּעַלְמָֽה׃
o caminho da águia no ar, o caminho da cobra na penha, o caminho do navio no meio do mar, e o caminho do homem com uma virgem.

Aristotle, in his Ethics describes the difference between animalistic life and human life as the difference between life governed wholly by the senses and life governed by a combination of the senses and the intellect. The former, being governed wholly by his senses, may, when hungry, eat something poisonous because its sense of hunger dominates it. Man, when in possession of his intellect, would first examine the food to ensure it is wholesome. When man ignores his intellect, he becomes beast-like, a slave to his instincts. Such surrender to his senses hastens his ultimate destiny, death. When the mating urge overcomes an animal, it will mate with the first available mate, irrespective of compatibility. Humans, when guided by their intellects, would display circumspection when choosing mates as life partners.
