The Perfect Cup of Coffee

Black as the Devil,
Hot as Hell,
Pure as an Angel,
Sweet as Love.

That’s the recipe for a perfect cup of coffee, according to the French statesman Charles Maurice de Talleyrand (1754-1838).
... and yes you're right, he forgot the most important ingredient - a good quality coffee beans.

Men Are Four (Arabic Apothegm)

He who knows not and knows not he knows not, he is a fool -- shun him;
He who knows not and knows he knows not, he is simple -- teach him;
He who knows and knows not he knows, he is asleep -- wake him.
He who knows and knows he knows, he is wise -- follow him.
