What looks like enjoyment is the sneer of contempt. That's not a smile.
It is remarkable by how much a pinch of malice enhances the penetrating power of an idea or an opinion. Our ears it seems are wonderfully attuned to sneers and evil reports about our fellow men.
The most insignificant people are the most apt to sneer at others. They are safe from reprisals. And have no hope of rising in their own self esteem but by lowering their neighbors.
A new idea is delicate. It can be killed by a sneer or a yawn it can be stabbed to death by a quip and worried to death by a frown on the right man's brow.
