Letters 82.13

But, as I was going on to remark, you see that death in itself is neither an evil nor a good; Cato experienced death most honourably, Brutus most basely. Everything, if you add virtue, assumes a glory which it did not possess before. We speak of a sunny room, even though the same room is pitch-dark at night.
