It is the mark of a mean, vulgar and ignoble spirit to dwell on the thought of food before meal times or worse to dwell on it afterwards, to discuss it and wallow in the remembered pleasures of every mouthful. Those whose minds dwell before dinner on the spit, and after on the dishes, are fit only to be scullions.
