Cattle are terrestrial and bent towards the earth.  Man, a celestial growth, rises superior to them as much by the mould of his bodily conformation as by the dignity of his soul.  What is the form of quadrupeds?  Their head is bent towards the earth and looks towards their belly, and only pursues their belly’s good.  Thy head, O man! is turned towards heaven; thy eyes look up. Arist., Part. An. iv. 10, 18.  μόνον ὀρθόν ἐστι τῶν ζῴων ὁ ἄνθρωπος.  When therefore thou degradest thyself by the passions of the flesh, slave of thy belly, and thy lowest parts, thou approachest animals without reason and becomest like one of them. cf. Ps. xlix. 12.  Thou art called to more noble cares; “seek those things which are above where Christ sitteth.” Col. iii. 1.  Raise thy soul above the earth; draw from its natural conformation the rule of thy conduct; fix thy conversation in heaven.  Thy true country is the heavenly Jerusalem; cf. Phil. iii. 20. thy fellow-citizens and thy compatriots are “the first-born which are written in heaven.” Heb. xii. 23.
