If a man insisted always on being serious, and never allowed himself a bit of fun and relaxation, he would go mad or become unstable without knowing it.
HerodotusThe man of affluence is not in fact more happy than the possessor of a bare competency, unless, in addition to his wealth, the end of his life be fortunate. We often see misery dwelling in the midst of splendour, whilst real happiness is found in humbler stations.
HerodotusThe Persians are very fond of wine ... It is also their general practice to deliberate upon affairs of weight when they are drunk; and then in the morning, when they are sober, the decision to which they came the night before is put before them by the master of the house in which it was made; and if it is then approved they act on it; if not, they set it aside. Sometimes, however, they are sober at their first deliberations, but in this case they always reconsider the matter under the influence of wine.
