The custom of festive gatherings probably originated in motives of conviviality and religion; these motives are also present in the later development, but they do not continue to be the sole motives. The latter-day leisure-class festivities and entertainments may continue in some slight degree to serve the religious need and in a higher degree the needs of recreation and conviviality, but they also serve an invidious purpose; and they serve it none the less effectually for having a colourable non-invidious ground in these more avowable motives. But the economic effect of these social amenities is not therefore lessened, either in the vicarious consumption of goods or in the exhibition of difficult and costly achievements in etiquette.
