Petty is the mind which delights in earthly things: it should be led away to those things which appear everywhere equally, everywhere equally lustrous. There is this too to consider, that earthly things stand in the way of genuine goods through a wayward belief in false goods. The longer people extend their colonnades, the higher they build their towers, the wider they stretch their walks, the deeper they dig their summer grottoes, the more massively they raise the roofs of their dining-halls, so much the more will there be to cut off the sight of heaven.
— Seneca, “Consolation to Helvia,” trans. C.D.N. Costa.
