When you swear, swear seriously and solemnly, but at the same time with a smile, for a smile is the twin sister of seriousness.
PlatoFor neither does wealth bring honour to the owner, if he be a coward; of such a one the wealth belongs to another, and not to himself. Nor does beauty and strength of body, when dwelling in a base and cowardly man, appear comely, but the reverse of comely, making the possessor more conspicuous, and manifesting forth his cowardice.
Plato
