Man usually avoids attributing cleverness to somebody else unless it is an enemy.

Now that cleverness was the fashion most people were clever – even perfect fools; and cleverness after all was often only a bore: all head and no body.

When you are without friends, the next best thing is an enemy who knows you well.

I sometimes think that 'friend' is just a word I use for all the people I haven't murdered yet.

Don't make the mistake of underestimating your enemies.

There’s a difference between a clever person and a smart one. Smart people make their own ways, and clever people use their minds to usurp opportunities to walk on the paths made by others.
