Epicurus, the great teacher of happiness, has correctly and finely divided human needs into three classes. First there are the natural and necessary needs which, if they are not satisfied, cause pain. Consequently, they are only victus et amictus [food and clothing] and are easy to satisfy. Then we have those that are natural yet not necessary, that is, the needs for sexual satisfaction. … These needs are more difficult to satisfy. Finally, there are those that are neither natural nor necessary, the needs for luxury, extravagance, pomp, and splendour, which are without end and very difficult to satisfy.
