No amount of common sense will ever prevail against a modicum of stupidity that is currently in fashion.

Your quote reminded me of this one:
"Only two things are infinite, the universe and human stupidity, and I'm not sure about the former."
Albert Einstein
I love Einstein quotes... he was a cracker! His humor and wit reminds me a lot of that of Mark Twain. Here are a few more good Einstein quotes:
"Gravitation cannot be held responsible for people falling in love. How on earth can you explain in terms of chemistry and physics so important a biological phenomenon as first love? Put your hand on a stove for a minute and it seems like an hour. Sit with that special girl for an hour and it seems like a minute. That's relativity."
-Albert Einstein
"I know not with what weapons World War III will be fought, but World War IV will be fought with sticks and stones. "
--Albert Einstein
In reference to his discoveries that led to the creation of the atom bomb...
"If I had only known, I would have been a locksmith."
--Albert Einstein
I thought many of you might find this one interesting:
"Nothing will benefit human health and increase the chances for survival of life on Earth as much as the evolution to a vegetarian diet. "
--Albert Einstein
"To punish me for my contempt for authority, fate made me an authority myself. "
--Albert Einstein
"The hardest thing in the world to understand is the income tax. "
--Albert Einstein, (attributed)
"The strongest force in the universe is compound interest."
--Albert Einstein, (attributed)
"If A is success in life, then A equals x plus y plus z. Work is x; y is play; and z is keeping your mouth shut."
--Albert Einstein, Observer, Jan. 15, 1950

Isn't that one a hoot?!!!
And one to leave you by:
"You see, wire telegraph is a kind of a very, very long cat. You pull his tail in New York and his head is meowing in Los Angeles. Do you understand this? And radio operates exactly the same way: you send signals here, they receive them there. The only difference is that there is no cat. "
--Albert Einstein, when asked to describe radio
