Three quotes for Today. Twain and Sagan quotes are quite similar, worth mentioning them both in this day and age. These are three of my favorite quotes:

“It’s easier to fool people than to convince them that they have been fooled”
– Mark Twain

“If we’ve been bamboozled long enough, we tend to reject any evidence of the bamboozle. It’s simply too painful to acknowledge, even to ourselves, that we’ve been taken. Once you give a charlatan power over you, you almost never get it back.”
― Carl Sagan

“It is difficult to get a man to understand something, when his salary depends on his not understanding it.”
– Upton Sinclair
