Excess
All the virtues by excess degenerate into vices.
Beware of excess.
Every excess becomes a vice.Latin.
Everything in excess is adverse to nature.Hippocrates.
He that exceeds the commission must answer for it at his own cost.German.
Nothing to excess.La Fontaine.
To gild refined gold, to paint the lily,
To throw a perfume on the violet,
To smooth the ice, or add another hue
Unto the rainbow, or with taper light
To seek the beauteous eye of Heaven to garnish,
Is wasteful and ridiculous excess.Shakespeare.
